Curcumin May Boost Cognitive Function, Mood, in People With Mild Age-Related Memory Loss
Curcumin is the substance that gives curry its yellow color. Previous studies have linked curcumin to anti-inflammatory and antioxidant properties. Now a recent study suggests that curcumin may boost memory, attention, and mood in people with mild, age-related memory loss.
Participants in the study included 40 people between the ages of 50 and 90 who had mild memory problems. Over the course of 18 months, they were given either 90 mg of curcumin or placebo twice daily.
All of the participants underwent standardized cognitive assessments at the beginning of the study and at six-month intervals until the conclusion of the study. The researchers monitored curcumin levels in the participants’ blood at the beginning of the study and at the 18-month point. Additionally, 30 participants underwent positron emission tomograophy (PET) scans at the beginning and end of the study in order to measure amyloid and tau levels in their brains. Amyloid and tau are biomarkers of Alzheimer’s disease.
At the conclusion of the study, the researchers noted a 28% improvement in memory and attention in the curcumin group, with no improvements in the placebo group. They also noted mild improvements in mood and significantly less amyloid and tau in the curcumin group, when compared with the placebo.
Researchers from UCLA conducted the study. it was published online ahead of print on January 19, 2018, in the American Journal of Geriatric Psychiatry.
Curcumin is present in turmeric but if you’re looking to get truly beneficial levels, it’s best to take it in supplement form.
