Highlights:
  • Curcumin has the ability to improve memory and mood in people with mild, age-related memory loss.
  • Theracurmin, containing 90mg of curcumin, a compound in turmeric was tested in non-demented adults.
  • The compound decreased plaque and tangle accumulation in brain regions modulating mood and memory.
A certain form of curcumin, an active compound in turmeric can improve memory and reduce the chances of dementia.

A study conducted by UCLA scientists examined the effects of an easily absorbed curcumin supplement on memory performance in people without dementia, as well as curcumin's potential impact on the microscopic plaques and tangles in the brains of people with Alzheimer's disease.

Curcumin has previously been shown to have anti-inflammatory and antioxidant properties in lab studies. It also has been suggested as a possible reason that senior citizens in India, where curcumin is a dietary staple, have a lower prevalence of Alzheimer's disease and better cognitive performance.

"Exactly how curcumin exerts its effects is not certain, but it may be due to its ability to reduce brain inflammation, which has been linked to both Alzheimer's disease and major depression," said Dr. Gary Small, the study's first author.

Curcumin Improves Cognition

The double-blind, placebo-controlled study involved 40 adults between the ages of 50 and 90 years who had mild memory complaints. Participants were randomly assigned to receive either a placebo or 90 milligrams of curcumin twice daily for 18 months.

All 40 subjects received standardized cognitive assessments at the start of the study and at six-month intervals, and monitoring of curcumin levels in their blood at the start of the study and after 18 months.

Thirty of the volunteers underwent positron emission tomography, or PET scans, to determine the levels of amyloid and tau in their brains at the start of the study and after 18 months.

  • The people who took curcumin experienced significant improvements in their memory and attention abilities.
  • In memory tests, the people taking curcumin improved by 28 percent over the 18 months.
  • Curcumin showed mild improvements in mood, and the brain PET scans showed significantly less amyloid and tau signals in the amygdala and hypothalamus than those who took placebos. The amygdala and hypothalamus are regions of the brain that control various memory and emotional functions.
The research team has plans to conduct a follow-up study with a larger number of people. That study will include some people with mild depression so the scientists can explore whether curcumin also has antidepressant effects.

The larger sample also would allow them to analyze whether curcumin's memory-enhancing effects vary according to people's genetic risk for Alzheimer's, their age or the extent of their cognitive problems.

"These results suggest that taking this relatively safe form of curcumin could provide meaningful cognitive benefits over the years," said Small, UCLA's Parlow-Solomon Professor on Aging.
