“Patient Five” was in his late 50s when a trip to the doctors changed his life.
He had diabetes, and he had signed up for a study to see if taking a “statin” – a kind of cholesterol-lowering drug – might help. So far, so normal.
But soon after he began the treatment, his wife began to notice a sinister transformation. A previously reasonable man, he became explosively angry and – out of nowhere – developed a tendency for road rage. During one memorable episode, he warned his family to keep away, lest he put them in hospital.
Out of fear of what might happen, Patient Five stopped driving. Even as a passenger, his outbursts often forced his wife to abandon their journeys and turn back. Afterwards, she’d leave him alone to watch TV and calm down. She became increasingly fearful for her own safety.
Then one day, Patient Five had an epiphany. “He was like, ‘Wow, it really seems that these problems started when I enrolled in this study’,” says Beatrice Golomb, who leads a research group at the University of California, San Diego.
... Over the years, Golomb has collected reports from patients across the United States – tales of broken marriages, destroyed careers, and a surprising number of men who have come unnervingly close to murdering their wives. In almost every case, the symptoms began when they started taking statins, then promptly returned to normal when they stopped; one man repeated this cycle five times before he realised what was going on.
Golomb first suspected a connection between statins and personality changes nearly two decades ago, after a series of mysterious discoveries, such as that people with lower cholesterol levels are more likely to die violent deaths. Then one day, she was chatting to a cholesterol expert about the potential link in the hallway at her work, when he brushed it off as obviously nonsense. “And I said ‘how do we know that?’,” she says.
Filled with fresh determination, Golomb scoured the scientific and medical literature for clues. “There was shockingly more evidence than I had imagined,” she says. For one thing, she uncovered findings that if you put primates on a low-cholesterol diet, they become more aggressive.
Golomb remains convinced that lower cholesterol can cause behavioural changes in both men and women
There was even a potential mechanism: lowering the animals’ cholesterol seemed to affect their levels of serotonin, an important brain chemical thought to be involved in regulating mood and social behaviour in animals. Even fruit flies start fighting if you mess up their serotonin levels, but it also has some unpleasant effects in people – studies have linked it to violence, impulsivity, suicide and murder.
If statins were affecting people’s brains, this was likely to be a direct consequence of their ability to lower cholesterol.
Since then, more direct evidence has emerged. Several studies have supported a potential link between irritability and statins, including a randomised controlled trial – the gold-standard of scientific research – that Golomb led, involving more than 1,000 people. It found that the drug increased aggression in post-menopausal women though, oddly, not in men.
In 2018, a study uncovered the same effect in fish. Giving statins to Nile tilapia made them more confrontational and – crucially – altered the levels of serotonin in their brains. This suggests that the mechanism that links cholesterol and violence may have been around for millions of years.
Golomb remains convinced that lower cholesterol, and, by extension, statins, can cause behavioural changes in both men and women, though the strength of the effect varies drastically from person to person. “There are lines of evidence converging,” she says, citing a study she conducted in Sweden, which involved comparing a database of the cholesterol levels of 250,000 people with local crime records. “Even adjusting for confounding factors, it was still the case that people with lower cholesterol at baseline were significantly more likely to be arrested for violent crimes.”.
The mean consumption of 62 food items from the FAOSTAT database (1993–2008) was compared with the actual statistics of five CVD [CVD=Cardio-Vascular Disease] indicators in 42 European countries. Several other exogenous factors (health expenditure, smoking, body mass index) and the historical stability of results were also examined.
...
The most significant dietary correlate of low CVD risk was high total fat and animal protein consumption.
Additional statistical analyses further highlighted citrus fruits, high-fat dairy (cheese) and tree nuts. Among other non-dietary factors, health expenditure showed by far the highest correlation coefficients.
The major correlate of high CVD risk was the proportion of energy from carbohydrates and alcohol, or from potato and cereal carbohydrates. Similar patterns were observed between food consumption and CVD statistics from the period 1980–2000, which shows that these relationships are stable over time.
...
Our results do not support the association between CVDs and saturated fat, which is still contained in official dietary guidelines. Instead, they agree with data accumulated from recent studies that link CVD risk with the high glycaemic index/load of carbohydrate-based diets. In the absence of any scientific evidence connecting saturated fat with CVDs, these findings show that current dietary recommendations regarding CVDs should be seriously reconsidered.
...
Low cholesterol levels correlate most strongly with the proportion of plant food energy in the diet (r=−0.87, p less than 0.001 in both sexes) and with sources of plant carbohydrates represented by items such as % PC CARB energy (r=−0.87 in men, r=−0.83 in women; p less than 0.001) (Fig. 2), % CA energy (r=−0.85 in men, r=−0.81 in women; p less than 0.001), and cereals (r=−0.74 in men, r=−0.73 in women; p less than 0.001). Smoking correlates quite strongly with lower cholesterol as well, but in men only (r=−0.62, p less than 0.001).
Remarkably, the relationship of raised cholesterol with CVD risk is always negative, especially in the case of total CVD mortality (r=−0.69 in men, r=−0.71 in women; p less than 0.001)
Discussion
Raised cholesterol correlates negatively with CVD risk
The results of our study show that animal fat (and especially its combination with animal protein) is a very strong predictor of raised cholesterol levels. This is in accordance with the meta-analyses of clinical trials, which show that saturated animal fat is the major trigger of raised cholesterol (6, 16). Interestingly, the relationship between raised cholesterol and CVD indicators in the present study is always negative. As shown in Figs. 3 and and Supplementary Figs. 1 and 2, this finding is visually less persuasive in the case of CVD mortality, where factors such as the quality of healthcare come to the foreground, but it is quite unambiguous in the case of women's raised blood pressure.
The negative relationship between raised cholesterol and CVD may seem counterintuitive, but it is not at variance with the available evidence. The largest of the recent worldwide meta-analyses dealing with cholesterol and CVD risk (17) observed a positive relationship between raised cholesterol and CVD mortality at younger ages, but this association gradually started to reverse in seniors, where the number of deaths is the highest. In fact, the relationship between raised cholesterol and stroke mortality in seniors was slightly negative. Both this study and other studies dealing with blood profiles of patients hospitalised with CVD events (18–22) demonstrate that low HDL (high-density lipoprotein associated) cholesterol (around ~1.0 mmol/L), or high total cholesterol: HDL-cholesterol ratio are the best indicators of CVD risk. Total cholesterol is usually normal or slightly elevated (4.5–5.5 mmol/L), and hence it cannot serve as a predictor of CVD events. Some other authors also point to high plasma triglycerides (which correlate with low HDL-cholesterol levels) (23), or to the ratio between triglycerides and HDL-cholesterol (24) as another useful risk indicators.
In this context it is important to note that saturated fat is not only the key trigger of high total cholesterol, but even high HDL-cholesterol and LDL (low-density lipoprotein associated)-cholesterol (16). Saturated fat also decreases triglyceride levels, but the total cholesterol: HDL-cholesterol ratio remains stable. The main sources of saturated fatty acids are red meat and milk products (whole fat milk, cheese, butter) (see Supplementary Table 1). Therefore, in Europe, where the consumption of animal products is the highest in the world, we can assume a strong connection between total cholesterol and HDL-cholesterol. Understandably, this relationship may not be so strong outside Europe and it may also vary depending on the individual diet. This could explain regional and individual differences in the relationship between total cholesterol and CVD risk.
Although the concurrent increase of LDL-cholesterol levels is often taken out of context and used as an argument against the intake of saturated fats in dietary recommendations (25), saturated fat is primarily tied to the less dense, large LDL particles (26), whereas cardiovascular risk is connected with the denser, small LDL particles (27), which accompany carbohydrate-based diets. There is also no evidence that the reduction of saturated fat intake (on its own) would decrease CVD risk (28). On the other hand, it is true, that so far, there is no clear evidence that saturated fat would be beneficial for the prevention of CVD. The only possible exception among the sources of saturated fat is dairy (29–31).
Major correlates of high CVD risk
Carbohydrates
The results of our study show that high-glycaemic carbohydrates or a high overall proportion of carbohydrates in the diet are the key ecological correlates of CVD risk. These findings strikingly contradict the traditional ‘saturated fat hypothesis’, but in reality, they are compatible with the evidence accumulated from observational studies that points to both high glycaemic index and high glycaemic load (the amount of consumed carbohydrates × their glycaemic index) as important triggers of CVDs (1, 32–34). The highest glycaemic indices (GI) out of all basic food sources can be found in potatoes and cereal products (Supplementary Table 2), which also have one of the highest food insulin indices (FII) that betray their ability to increase insulin levels.
The role of the high glycaemic index/load can be explained by the hypothesis linking CVD risk to inflammation resulting from the excessive spikes of blood glucose (‘post-prandial hyperglycaemia’) (35). Furthermore, multiple clinical trials have demonstrated that when compared with low-carbohydrate diets, a low-fat diet increases plasma triglyceride levels and decreases total cholesterol and HDL-cholesterol, which generally indicates a higher CVD risk (36, 37). Simultaneously, LDL-cholesterol decreases as well and the number of dense, small LDL particles increases at the expense of less dense, large LDL particles, which also indicates increased CVD risk (27). These findings are mirrored even in the present study because cereals and carbohydrates in general emerge as the strongest correlates of low cholesterol levels.
Discrepancy in the old statistics: The root of the ‘saturated fat hypothesis’?
The paradoxical results of our historical comparison (men's statistics from 1980 and 1990) have an interesting analogy in the ‘Seven Countries Study’, which stood behind the current ‘saturated fat paradigm’. The authors of this longitudinal ecological research, finished in the early 1980s, concluded that men's CHD [CHD=Coronary Heart Disease] mortality in seven countries correlated positively with high blood pressure, high cholesterol, and high saturated fat intake, but the relationship of high blood pressure and high cholesterol with men's stroke mortality (in 12 cohorts from six countries) was strongly negative (54). Because CHD mortality was the central CVD [CVD=Cardio-Vascular Disease] indicator in this study, we think that the authors did not pay sufficient attention to this discrepancy and they contented themselves with the fact that stroke mortality was positively associated with high blood pressure at the individual level. Ironically, in the following decades, the ecological relationship of CHD with risk factors completely reversed.
...Second, the effect of increased longevity in highly developed countries, after the eradication of serious infectious diseases after World War II, led to a temporary epidemic of CVDs, which also coincided with rapidly improving living standards and the increasing consumption of animal food. Because of the chronic nature of CVDs, this dietary change may have brought health benefits only after several decades and as a result, the relationship of CVD indicators to animal products has reversed with a certain delay (Supplementary Figs. 42–47). In the eastern half of Europe, this phenomenon started to fully manifest only very recently (possibly in combination with heavy alcohol drinking), which led to the increase of CVD rates.
The obvious fallacy of the ‘saturated fat hypothesis’ can be demonstrated by the example of France – a country with the highest intake of animal fat in the world and the second lowest CVD mortality (after Japan) (56). In fact, if we use a limited sample of 24 countries (without the former republics of USSR, Czechoslovakia and Yugoslavia, and Luxembourg), a summary mean of food consumption from the last half-century (1961–2008) produces very similar results like the mean for the period 1993–2008 (Table 4), reaching r=0.82 between % CA [CA=carbohydrates] energy and raised blood pressure in women.

UCLA scientists have identified specific gut bacteria that play an essential role in the anti-seizure effects of the high-fat, low-carbohydrate ketogenic diet. The study, published today in the journal Cell, is the first to establish a causal link between seizure susceptibility and the gut microbiota—the 100 trillion or so bacteria and other microbes that reside in the human body's intestines.
...
In a study of mice as a model to more thoroughly understand epilepsy, the researchers found that the diet substantially altered the gut microbiota in fewer than four days, and mice on the diet had significantly fewer seizures.
To test whether the microbiota is important for protection against seizures, the researchers analyzed the effects of the ketogenic diet on two types of mice: those reared as germ-free in a sterile laboratory environment and mice treated with antibiotics to deplete gut microbes.
"In both cases, we found the ketogenic diet was no longer effective in protecting against seizures," said lead author Christine Olson, a UCLA graduate student in Hsiao's laboratory. "This suggests that the gut microbiota is required for the diet to effectively reduce seizures."
The biologists identified the precise order of organic molecules known as nucleotides from the DNA of gut microbiota to determine which bacteria were present and at what levels after the diet was administered. They identified two types of bacteria that were elevated by the diet and play a key role in providing this protection: Akkermansia muciniphila and Parabacteroides species.
...
How do the bacteria do this? "The bacteria increased brain levels of GABA—a neurotransmitter that silences neurons—relative to brain levels of glutamate, a neurotransmitter that activates neurons to fire," said co-author Helen Vuong, a postdoctoral scholar in Hsiao's laboratory.
"This study inspires us to study whether similar roles for gut microbes are seen in people that are on the ketogenic diet," Vuong said.

Why It’s now time for a full public parliamentary inquiry into the controversial drug and fully expose the great cholesterol and statin con
Earlier this week, the Chair of the British Parliament Science and Technology Committee, Sir Norman Lamb MP made calls for a full investigation into cholesterol lowering statin drugs. It was instigated after a letter was written to him signed by a number of eminent international doctors including the editor of the BMJ, the Past President of the Royal College of Physicians and the Director of the Centre of Evidence Based Medicine in Brazil wrote a letter calling for a full parliamentary inquiry into the controversial medication[1]. It’s lead author Cardiologist Dr Aseem Malhotra makes the case for why’s there’s an urgent need for such an investigation in European Scientist.
A few weeks ago, an alarmed and confused patient in his late forties, who I shall call Mr Smith, came to see me for a consultation. Four years earlier he suffered a heart attack where severe blockages were found in his right coronary artery. These were opened up and kept open with metal stents.
He was prescribed atorvastatin, which is standard practice for heart attack patients regardless of cholesterol levels. Unfortunately, the atorvastatin caused severe muscle pains on exercise. Fortunately, his symptoms disappeared within a week of stopping the drug.
As an alternative to his statin, he decided to adopt an ultra-low fat vegan diet which he believed may halt, even reverse heart disease through lowering cholesterol. Within months he dropped his total cholesterol by 40% from 5.2mmol/L to 3.2, now placing his levels in the bottom five per cent of the population.
Despite sticking religiously to the diet, he began to develop chest pain when he did exercise, and a repeat heart scan showed a seventy per cent blockage in another artery, one that had been completely clear four years before. “How is this possible?” he asked me, clearly upset. ‘How could I develop more heart disease in such a short space of time with such low cholesterol?’
I explained to him his case was not unusual, nor inexplicable.
...
Rather than accept greater scrutiny, highly influential cardiologists are attacking those who question the benefits of statins. Those who believed that side effects are much more prevalent are denounced as peddlers of “fake news” or “fake science”. They are compared to “anti – vaxxers”.One Cardiologist, Ana Navar even wrote in a recent editorial in JAMA Cardiology that inappropriate fears about statin side effects are coming from social media wellness bloggers and that “lives lost from inappropriate concerns about statins may number in the millions” but this is not evidence based. The side effect literature and remarkably high discontinuation rate comes from very credible sources[21].
The largest statin survey in the United States exposes 75% of those prescribed the medication stop it within a year of prescription with 62% of those stating side effects as the reason
Even as far back as 2002 when there was no social media or public awareness of statin side effects a paper in JAMA of over 40,000 patients reveals that 60% of heart attack patients aged over 65 will stop the drug within 2 years (ref)
...
So how effective are statins in preventing and treating heart disease?
When one removes the industry funded PR and hype, the results are pretty underwhelming.
In 2015, new research published in BMJ Open revealed that despite tens of millions more people being prescribed statins across many European countries there was no evidence that this had any effect on cardiovascular mortality, over a twelve year period[24].
If you strip down the statin trials to their moving parts, the data actually reveals that, even in those who have established heart disease, the benefits are very small. Even in this high risk group, the average increase in life expectancy from taking the drug religiously for five years is a meagre four days[25].
...
We continue to have an epidemic of misinformed doctors and misinformed and unwittingly deceived and harmed patients. In large part this has been driven by a multi-billion-dollar food and drug industry that profits from the fear of cholesterol.
It’s now time for a full public parliamentary inquiry to push for the raw data on statins find out who really benefits, and to determine who has been manipulating and hiding data on the debilitating side effects that appear to possibly affect almost half taking the drug. Until then it’s better we focus healthcare resources in tackling the real root cause of heart disease through prioritising lifestyle changes. It’s finally time to stop falling for the great cholesterol and statin con.

Diets high in refined starches such as breads and cereals increase insulin levels. This affects the development of the eyeball, making it abnormally long and causing short-sightedness, suggests a team led by Loren Cordain, an evolutionary biologist at Colorado State University in Fort Collins, and Jennie Brand Miller, a nutrition scientist at the University of Sydney.
The theory could help explain the dramatic increase in myopia in developed countries over the past 200 years. It now affects 30 per cent of people of European descent, for example.
“The rate of starch digestion is faster with modern processed breads and cereals,” says Brand Miller. In response to this rapid digestion, the pancreas pumps out more insulin. High insulin is known to lead to a fall in levels of insulin-like binding protein-3, the team points out.
That could disturb the delicate choreography that normally coordinates eyeball lengthening and lens growth. And if the eyeball grows too long, the lens can no longer flatten itself enough to focus a sharp image on the retina, they suggest.
...
But while reading may play a role, it does not explain why the incidence of myopia has remained low in societies that have adopted Western lifestyles but not Western diets, says Cordain.
“In the islands of Vanuatu they have eight hours of compulsory schooling a day,” he says, “yet the rate of myopia in these children is only two per cent.” The difference is that Vanuatuans eat fish, yam and coconut rather than white bread and cereals.
The theory is also consistent with observations that people are more likely to develop myopia if they are overweight or have adult-onset diabetes, both of which involve elevated insulin levels. The progression of myopia has also been shown to be slower in children whose protein consumption is increased.

Findings
This cohort study included 146152 individuals from the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial and found that aspirin use 3 or more times per week was associated with reduced risk of all-cause, cancer, gastrointestinal cancer, and colorectal cancer mortality.
Results
A total of 146152 individuals (mean [SD] age at baseline, 66.3 [2.4] years; 74742 [51.1%] women; 129446 [88.6%] non-Hispanic white) were included in analysis. The median (interquartile range) follow-up time was 12.5 (8.7-16.4) years, encompassing 1822164 person-years. Compared with no use, aspirin use 1 to 3 times per month was associated with reduced risk of all-cause mortality (HR, 0.84; 95% CI, 0.80-0.88; P less than .001) and cancer mortality (HR, 0.87; 95% CI, 0.81-0.94; P less than .001). Aspirin use 3 or more times per week was associated with decreased risk of mortality of all causes (HR, 0.81; 95% CI, 0.80-0.83; P less than .001), any cancer (HR, 0.85; 95% CI, 0.81-0.88; P less than .001), GI cancer (HR, 0.75; 95% CI, 0.66-0.84; P less than .001), and CRC (HR, 0.71; 95% CI, 0.61-0.84; P less than .001).
.
The idea behind the hypothesis occurred to Esme Fuller-Thomson, professor at the University of Toronto’s Factor-Inwentash Faculty of Social Work (FIFSW) after learning about recent research conducted in South India. This study newly identified a link between schizophrenia and a variant of the gene NAPRT1, which lowers the body’s ability to use niacin, or Vitamin B3, which naturally occurs in meat, poultry, fish, and eggs.
“When I read this study a light bulb went on in my head,” says Fuller-Thomson, who published the hypothesis in the journal Schizophrenia Research this month with doctoral student, Rukshan Mehta. “This seems to be the missing link that explains all these medical mysteries.”
The researchers speculate that there is a critical interaction between an expectant mother’s prenatal niacin deficiency due to malnourishment and the NAPRT1 variant that impedes the fetus’ ability to use niacin. This interaction between the gene and the prenatal environment may predispose the offspring to develop a psychotic disorder.
Several studies indicate that the offspring of mothers who experience famine in their first trimester of pregnancy have double the chance of developing schizophrenia. Most researchers assume nutrient deficiency must be playing a role, but the particular nutrient has yet to be identified. Fuller Thomson now speculates that niacin may be the key nutrient involved.
Results: Prostate cancer and BPH patients presented higher total, fT and bT levels than CG. IGF-1, insulin and HOMA index were higher in BPH than in the other two groups.

Abstract
It has been established that there is a correlation between Alzheimer's disease and apolipoprotein E, specifically the ApoE4 genetic variant. However, the correlation between Apoe4, insulin resistance and metabolic syndrome (MetS) pathologies still remains elusive. As apolipoprotein E has many important physiological functions, individuals with the ApoE4 allele variant, also known as the Alzheimer's disease gene, are primarily at a greater risk for physiological consequences, specifically cognitive impairment (Chan et al., 2016). In this case study, a 71-year old female, heterozygous for ApoE4 with a family history of Alzheimer's Disease (AD) and the dual diagnosis of mild AD/metabolic syndrome (MetS) was placed on a 10-week nutrition protocol purposed at raising plasma ketones through carbohyrdrate restricted, high fat ketogenic diet (KD), time- restricted eating and physical/cognitive exercise. Primary biomarkers for MetS were measured pre/mid-/post intervention. The MoCA (Montreal Cognitive Assessment) was administered pre/post intervention by a licensed clinical therapist. The results were statistically significant. The HOMA-IR decreased by 75% from 13.9 to 3.48. Triglycerides decreased by 50% from 170mg/dL to 85mg/dL. VLDL dropped by 50% from 34mg/dL to 17mg/dL, and HgA1c decreased from 5.7% to 4.9%. The baseline MoCA score was 21/30; post treatment score was 28/30. The significant results in both MetS biomarkers and the MoCA score suggest that a ketogenic diet may serve to rescue cognition in patients with mild AD. The results of this case study are particularly compelling for ApoE4 positive (ApoE4+) subjects as ketogenic protocols extend hope and promise for AD prevention.

Long-term, high nut consumption could be the key to better cognitive health in older people according to new research from the University of South Australia.
In a study of 4822 Chinese adults aged 55+ years, researchers found that eating more than 10 grams of nuts a day was positively associated with better mental functioning, including improved thinking, reasoning and memory.
Lead researcher, UniSA’s Dr Ming Li, says the study is the first to report an association between cognition and nut intake in older Chinese adults, providing important insights into increasing mental health issues (including dementia) faced by an ageing population.
“Population aging is one of the most substantial challenges of the twenty-first century. Not only are people living longer, but as they age, they require additional health support which is placing unprecedented pressure on aged-care and health services,” Dr Li says.

...A year later, the man’s condition worsened. He developed fatigue, fever and shortness of breath, and it turned out he had a cancer of the blood called acute myeloid leukemia. He’d need a bone-marrow transplant to survive. After the procedure came the miracle. The man’s delusions and paranoia almost completely disappeared. His schizophrenia seemingly vanished.
Years later, “he is completely off all medication and shows no psychiatric symptoms,” Dr. Miyaoka told me in an email. Somehow the transplant cured the man’s schizophrenia.
A bone-marrow transplant essentially reboots the immune system. Chemotherapy kills off your old white blood cells, and new ones sprout from the donor’s transplanted blood stem cells. It’s unwise to extrapolate too much from a single case study, and it’s possible it was the drugs the man took as part of the transplant procedure that helped him. But his recovery suggests that his immune system was somehow driving his psychiatric symptoms.
...
In the late 19th century, physicians noticed that when infections tore through psychiatric wards, the resulting fevers seemed to cause an improvement in some mentally ill and even catatonic patients.
Inspired by these observations, the Austrian physician Julius Wagner-Jauregg developed a method of deliberate infection of psychiatric patients with malaria to induce fever. Some of his patients died from the treatment, but many others recovered. He won a Nobel Prize in 1927.
One much more recent case study relates how a woman’s psychotic symptoms — she had schizoaffective disorder, which combines symptoms of schizophrenia and a mood disorder such as depression — were gone after a severe infection with high fever.
...
Indeed, in the past 15 years or so, a new field has emerged called autoimmune neurology. Some two dozen autoimmune diseases of the brain and nervous system have been described. The best known is probably anti-NMDA-receptor encephalitis, made famous by Susannah Cahalan’s memoir “Brain on Fire.” These disorders can resemble bipolar disorder, epilepsy, even dementia — and that’s often how they’re diagnosed initially. But when promptly treated with powerful immune-suppressing therapies, what looks like dementia often reverses. Psychosis evaporates. Epilepsy stops. Patients who just a decade ago might have been institutionalized, or even died, get better and go home.
...
Dr. Robert Yolken, a professor of developmental neurovirology at Johns Hopkins, estimates that about a third of schizophrenia patients show some evidence of immune disturbance. “The role of immune activation in serious psychiatric disorders is probably the most interesting new thing to know about these disorders,” he told me.
Studies on the role of genes in schizophrenia also suggest immune involvement, a finding that, for Dr. Yolken, helps to resolve an old puzzle. People with schizophrenia tend not to have many children. So how have the genes that increase the risk of schizophrenia, assuming they exist, persisted in populations over time? One possibility is that we retain genes that might increase the risk of schizophrenia because those genes helped humans fight off pathogens in the past. Some psychiatric illness may be an inadvertent consequence, in part, of having an aggressive immune system.
...
Another case study from the Netherlands highlights this still-mysterious relationship. In this study, on which Dr. Yolken is a co-author, a man with leukemia received a bone-marrow transplant from a schizophrenic brother. He beat the cancer but developed schizophrenia. Once he had the same immune system, he developed similar psychiatric symptoms.
...
And there may be other, softer interventions. A decade ago, Dr. Miyaoka accidentally discovered one. He treated two schizophrenia patients who were both institutionalized, and practically catatonic, with minocycline, an old antibiotic usually used for acne. Both completely normalized on the antibiotic. When Dr. Miyaoka stopped it, their psychosis returned. So he prescribed the patients a low dose on a continuing basis and discharged them.
Minocycline has since been studied by others. Larger trials suggest that it’s an effective add-on treatment for schizophrenia. Some have argued that it works because it tamps down inflammation in the brain. But it’s also possible that it affects the microbiome — the community of microbes in the human body — and thus changes how the immune system works.
...
The study is preliminary, but it suggests that targeting immune function may improve mental health outcomes and that tinkering with the microbiome might be a practical, cost-effective way to do this.
...epidemiological and pathophysiological studies suggest that hyperglycemia may be largely responsible for CVD. Blood glucose has been reported as an independent predictor of atherosclerosis and blood glucose level greater than 90 mg/dl can lead to atherosclerosis in the carotid artery [125]. Long-term follow up data from patients with type 1 and type 2 diabetes suggest that hyperglycemia is a risk factor for diabetes related diseases and CVDMoreover, it has been suggested by Salvin et al. [126] that a 1 unit increase in the total glycosylated hemoglobin or HbA1C, can increase the risk of CVD by up to 18%. Even in the absence of overt diabetes, impairment in the glucose homeostasis can affect the cardiac autonomic function leading to high risk of cardiac diseases [127].
...
In this sense, recently it has been shown that cyclic ketone bodies preserve “young cardiac phenotype” in old mice [167]. On the other hand, it has been reported that isocaloric ketogenic diet (very low in carbohydrates and high in fats and/or proteins) increases lifespan [168].
Overall, insulin resistance contributes to generate CVD via two independent pathways: (1) atheroma plaque formation and (2) ventricular hypertrophy and diastolic abnormality.

In their study, the research team explores the link between calorie restriction (eating less or fasting) and delaying aging, which is unknown and has been poorly studied. The findings are published in the journal Molecular Cell.
The researchers identified an important, small molecule that is produced during fasting or calorie restriction conditions. The molecule, β-Hydroxybutyrate, is one type of a ketone body, or a water-soluble molecule that contains a ketone group and is produced by the liver from fatty acids during periods of low food intake, carbohydrate restrictive diets, starvation and prolonged intense exercise.
The researchers reported that β-Hydroxybutyrate delays vascular aging by providing a chemical link between calorie restriction and fasting and the anti-aging effect.
This compound can delay vascular aging of the endothelial cells, which line the interior surface of blood vessels and lymphatic vessels, preventing a type of cell aging called senescence, or cellular aging.
Senescent cells can no longer multiple and divide. The researchers found β-Hydroxybutyrate can promote cell division and prevent these cells from becoming old. Because this molecule is produced during calorie restriction or fasting, when people overeat or become obese this molecule is possibly suppressed, which would accelerate aging.
In addition, the researchers found when β-Hydroxybutyrate binds to a certain RNA-binding protein, this increases activity of a stem cell factor called Octamer-binding transcriptional factor (Oct4) in vascular smooth muscle and endothelial cells in mice.
Stem cell factor Oct4 increases a key factor against DNA damage-induced senescence, which can keep blood vessels young.

Results
During 23,196 person-years of follow-up (median per person, 7.5 years), 1059 (34.3%) participants died. Compared to normal total cholesterol (<5.18 mmol/l), borderline-high (5.18-6.21 mmol/l) and high (≥6.22 mmol/l) total cholesterol were associated with a decreased risk of all-cause mortality, with the multiple-adjusted hazard ratio (95% confidence interval, CI) of 0.71 (0.61–0.83) and 0.68 (0.57–0.80), respectively (P for trend <0.001). The competing risk regression models revealed that the reduced all-cause mortality associated with high total cholesterol (≥6.22 mmol/l)) was mainly due to the reduced risk of non-cardiovascular mortality (hazard ratio = 0.67, 95% CI = 0.51-0.88). These associations were statistically evident only among individuals without use of cholesterol-lowering medications.
Conclusions
The inverse association between high total cholesterol and reduced all-cause mortality in older adults is primarily due to non-cardiovascular mortality, especially among those who are not treated with cholesterol-lowering medications.
The new research uses a double mutant in which the insulin signaling (IIS) and TOR pathways have been genetically altered. Because alteration of the IIS pathways yields a 100 percent increase in lifespan and alteration of the TOR pathway yields a 30 percent increase, the double mutant would be expected to live 130 percent longer. But instead, its lifespan was amplified by 500 percent.

An 82 year old woman with chronic paranoid schizophrenia since age 17
The first patient documented in the Schizophrenia Research article is a woman who spent nearly her whole life suffering chronic, treatment-resistant schizophrenia. For more than 50 years, she endured paranoia, disorganized speech, visual and auditory hallucinations. By the time she was 70, she was suicidal and had been hospitalized repeatedly for psychosis or suicide attempts. She had been treated with over ten different antipsychotic and mood stabilizing medications, including regular antipsychotic injections. None of them helped her symptoms. She was unable to care for herself and had a court-appointed guardian and home health services.
At the age of 70, weighing 330 pounds, she went to a medical weight loss clinic and was started on a ketogenic diet. Within two weeks of starting the diet, she reported a noticeable reduction not only in her weight but also her psychotic symptoms. Within several months, she started to feel so much better that she was able to stop taking her psychiatric medications while remaining on the diet. Over time, her mood stabilized, and her hallucinations and paranoia remitted completely. She was no longer suicidal. Her case was first reported in 2009.
Today, 12 years later, she has lost a total of 150 pounds and remains on the ketogenic diet. She takes no medications and remains symptom-free. She was able to regain her independence, no longer requiring the guardian and the home health care team. When I recently spoke with her, she recalled her decades of suffering and hopelessness, and said that since starting the diet, she has had a "new life," and is happy to be alive.
A 39 year old woman with schizophrenia for 20 years
The second patient described in the article is a thirty-nine year old woman who suffered from depression, anxiety, anorexia nervosa, hallucinations and paranoia since her teens. As patients sometimes do, she concealed her psychotic symptoms when she was initially treated for depression and anorexia. When she finally reported her psychotic symptoms later in her twenties, she was diagnosed with schizophrenia. For the next ten years, she was treated with 7 different antipsychotic medications—including clozapine (called the “gold standard antipsychotic medication”) - along with antidepressants and anti-anxiety medications. Nevertheless, she continued to have symptoms.
She was having chronic gastrointestinal problems, so she saw a doctor who recommended the ketogenic diet. Noticing some improvement of her symptoms and being frustrated with all of her psychiatric medications, she unwisely stopped taking all 14 of her medications “cold turkey.” This sent her into severe psychosis requiring an extended hospitalization. In the hospital, she was re-medicated with Haldol-decanoate (an injectable medication which had not worked for her previously) and she continued the ketogenic diet. Within a month on both Haldol and the ketogenic diet, she reported complete remission of her psychotic symptoms for the first time since she was 14. Over the following year, she slowly tapered off Haldol, and remained free of psychotic symptoms. Of note, she lost 70 pounds from the diet, which exacerbated her anorexia. She has since regained 30 of those pounds and maintains a healthy weight today. 5 years after starting the ketogenic diet, she is off all antipsychotic medications, remains on the diet, and is free of all psychotic symptoms. She has since finished graduate school and now works full time.
Interestingly, these aren’t the first reports of the ketogenic diet for schizophrenia
While inspiring, these two case reports join a growing body of evidence supporting the use of the ketogenic diet in the treatment of schizophrenia.
Schizophrenia in 1965
In 1965, ten women hospitalized with schizophrenia who were already receiving medications and electroconvulsive therapy (ECT or “shock therapy”) were also placed on the ketogenic diet for a month. The researchers reported that their symptoms improved after two weeks on the diet, but then returned back to their baseline level of symptoms after the diet was stopped.
Schizoaffective disorder in 2017
In 2017, I reported two other cases of schizoaffective disorder improving significantly on the ketogenic diet. Schizoaffective disorder is a diagnosis that includes both a mix of schizophrenia and a mood disorder, often bipolar disorder. One man and one woman, both in their 30’s, had suffered treatment-resistant schizoaffective disorder for years. On the diet, their symptoms were greatly improved, and they both lost significant amounts of weight. Off the diet, their symptoms returned.
Schizophrenia in Ecuador
In 2018, two Ecuadorian twins, one male and one female, diagnosed with schizophrenia since the ages of 14 and 18 were started on a 6-week trial of the ketogenic diet. This study had a psychiatrist rate each twin’s symptoms while being unaware of their diet status. Interestingly, only when the patients were compliant with the diet did their symptoms improve. They also both lost weight. When they stopped the diet at the end of the study, their symptoms returned to their baseline level.
Patients with psychotic disorders are at high risk for type 2 diabetes mellitus, and there is increasing evidence that patients display glucose metabolism abnormalities before significant antipsychotic medication exposure. In the present study, we examined insulin action by quantifying insulin sensitivity in first episode psychosis (FEP) patients and unaffected siblings, compared to healthy individuals, using a physiological-based model and comprehensive assessment battery. Twenty-two unaffected siblings, 18 FEP patients and 15 healthy unrelated controls were evaluated using a 2-hour oral glucose tolerance test (OGTT), with 7 samples of plasma glucose and serum insulin concentration measurements. Insulin sensitivity was quantified using the oral minimal model method. Lipid, leptin, free fatty acids and inflammatory marker levels were also measured. Anthropometric, nutrient and activity assessments were conducted; total body composition and fat distribution were determined using whole-body dual energy x-ray absorptiometry. Insulin sensitivity significantly differed among groups (F=6.01, P=0.004), with patients and siblings showing lower insulin sensitivity, compared to controls (P=0.006, and P=0.002, respectively).
Those mice that received the transplants from schizophrenic patients had higher levels of glutamine in the serum and hippocampus, decreased glutamate in the hippocampus, and increased GABA in the hippocampus. These difference were localized to areas of the brain particularly rich in glutamate and its metabolites (i.e., the outer shell of the brain and the hippocampus). This means that a transplant of a different microbiome led to different GABA-glutamate-glutamine neurotransmission in mouse brains. Corresponding human brain areas are related to memory, neuron repair, and executive functioning, all significantly impacted in schizophrenia.
In addition, the schizophrenia microbiome recipient mice had different behaviors than the healthy control mice, with exaggerated startle response and increased activity.
