Research shows DHEA has no effect on cognitive function

Research shows DHEA has no effect on cognitive function

New research has highlighted that DHEA supplements have no benefits for the cognitive function in healthy, elderly adults.

Outlining their results in the Journal of the American Geriatrics Society, researchers concluded that as such the supplements should not be recommended for enhancement of cognitive function or general well-being.

DHEA is a naturally-occurring hormone in the human body which declines with age. At 70-years-old DHEA levels are only 20 per cent of that they were at their peak.

The team's conclusion was based on the results of a year-long study into the effects of the hormone on elderly, healthy individuals.

After receiving a 50 milligram dose of the medication, or a placebo, for one year, the participants undertook six cognitive tests in addition to having their depression levels and perceptions of their own health measured.

"We found that, although youthful levels of DHEA were restored in the group on treatment, the DHEA supplements had no benefits for cognitive function in these healthy older adults," states Donna Kritz-Silverstein, lead author of the study.

It was also recorded that there was no difference in any of the quality of life measures between the two research groups.

This follows news from Arthritis Care that the effectiveness of taking supplements to lessen the symptoms of arthritis is unproven.
