Ginkgo Biloba May Help Improve Memory in Seniors with Dementia
Taking 240 mg of Ginkgo biloba daily showed improvement in cognitive function for seniors with dementia.
Summary
In plain language
This study explored the use of Ginkgo biloba, a natural extract, to help manage symptoms of dementia in older adults. Researchers found that taking 240 mg daily of this supplement led to noticeable improvements in memory and cognitive function compared to a placebo. Importantly, the study also highlighted that Ginkgo biloba was well-tolerated, with fewer side effects leading to discontinuation than the placebo. Although promising, it's essential for seniors to discuss with their healthcare providers before starting any new supplement.

The study reviewed multiple clinical trials to understand the effects of Ginkgo biloba on dementia. Here's what you need to know:
Researchers conducted a meta-analysis, which means they combined data from several studies to get a clearer picture of the effects of Ginkgo biloba on dementia symptoms.
They found that a daily dose of 240 mg improved cognitive scores, indicating better memory performance, and had fewer side effects compared to a placebo group.
While the results are promising, the study noted that not all cognitive tests showed significant improvements, suggesting the need for further research.
If you're considering Ginkgo biloba, talk to your healthcare provider to see if it's a suitable option for you.
