Ginkgo biloba extract may offer no cognitive protection

Experts have failed to find evidence that ginkgo biloba extract (GBE) protects against cognitive decline in the elderly.

A 42-month study of 118 elderly people over the age of 85 years has found that taking GBE does not reduce the progression of decline down the clinical dementia rating scale.

Experts also found no reduction in memory function decline among those taking GBE.

The researchers concluded that GBE does not exert any protective effect against congnitive decline.

However, they suggest that this may be due to the limited statistical power of the study and the small number of participants.

They suggest that larger studies, taking into account medication adherence, may clarify the effectiveness of CBE.
