Review Meta Analysis
Efficacy and adverse effects of ginkgo biloba for cognitive impairment and dementia: a systematic review and meta-analysis.
Research into Ginkgo biloba has been ongoing for many years, while the benefit and adverse effects of Ginkgo biloba extract EGb761 for cognitive impairment and dementia has been discussed controversially. ⋯ EGb761 at 240 mg/day is able to stabilize or slow decline in cognition, function, behavior, and global change at 22-26 weeks in cognitive impairment and dementia, especially for patients with neuropsychiatric symptoms.

Recent studies have indicated that repetitive transcranial magnetic stimulation (rTMS) could improve cognitive function in people with Alzheimer's disease (AD). Yet the results are inconclusive. ⋯ This meta-analysis supports that high frequency rTMS stimulation on right- or bilateral-DLPFC has significant therapeutic effect on cognitive function in patients with mild to moderate AD. Due to small number of studies included, more well-controlled rTMS studies should be evaluated in AD patients in the future.
