In a recent study, people who like to eat curry have benefits again:
Daily consumption of some form of curcumin (a substance that gives Indian curry a bright color) can improve the slight memory decline and emotional problems that occur with age.
The study, published recently in the American Journal of Geriatric Psychiatry, tested the effect of an easily absorbed curcumin supplement on the memory of people without dementia, and curcumin on plaques in the brains of Alzheimer’s patients And the potential impact of entanglement.
Curcumin is found in turmeric. Past laboratory studies have found that it has anti-inflammatory and antioxidant properties. It is also believed that curcumin may be the reason for the lower rate of Alzheimer's disease and better cognitive ability among the elderly in India.
The first author of the article, Dr. Gary Small from the Department of Geriatric Psychiatry at the UCLA Semel Institute of Neuroscience and Human Behavior, is also the head of the Department of Geriatric Psychiatry at the UCLA Longevity Center. He said: "The mechanism of how curcumin exerts its effects is not yet Clearly, it may be because it can reduce brain inflammation associated with Alzheimer’s and severe depression.”
All 40 subjects received a standardized cognitive assessment at the beginning of the study and every six months, and their blood curcumin levels were monitored at the beginning of the study and 18 months later.
Thirty volunteers underwent positron emission tomography or PET scans to determine the levels of amyloid and tau in the brain at the beginning of the study and 18 months later.

Thirty volunteers underwent positron emission tomography or PET scans to determine the levels of amyloid and tau in the brain at the beginning of the study and 18 months later.
The memory and concentration of subjects in the curcumin test group were significantly improved, while the control group did not.
In the memory test, the test group's score rose by 28% after 18 months, and their mood improved slightly. PET scans of their brains showed that the amyloid and tau signals in the amygdala and hypothalamus were significantly less than those of those taking placebo.
The two brain regions, the amygdala and hypothalamus, control certain memory and emotional functions.
In addition, four subjects who took curcumin and two subjects who took placebo experienced mild side effects, such as abdominal pain and nausea.
The researchers plan to recruit more people for follow-up research. This study will include some patients with mild depression, so scientists can explore whether curcumin also has antidepressant effects. A larger sample will allow researchers to analyze whether curcumin's memory-improving effect is different due to certain factors, such as the genetic risk of Alzheimer's disease, age, and the severity of cognitive problems.
Professor Small said: "These results show that long-term use of this relatively safe curcumin is beneficial to cognitive ability."
