This randomized, controlled, double-blind, multicenter clinical trial studied 410 outpatients with mild to moderate dementia to determine the effects of Ginkgo biloba extract EGb 761(®) on the neuropsychiatric symptoms of dementia.
Randomly allocated patients were given 240 mg of EGb 761(®) or a placebo once daily for a period of 24 weeks. Treatment with EGb 761(®) was significantly superior to the placebo for treatment of the symptoms apathy / indifference, sleep / night-time behavior, irritability / lability, depression / dysphoria, and aberrant motor behavior. Caregivers’ distress evaluation showed similar improvements.
Treatment with EGb 761(®), with a daily dose of 240 mg, was found to be safe, to effectively alleviate behavioral and neuropsychiatric symptoms in patients with mild to moderate dementia, and to improve the wellbeing of carers.
