Ginko biloba: Some research shows it does not improve cognition without cognitive impairment does not prevent dementia; may improve cognitive function with Alzheimer disease (AD) or vascular dementia (VaD). The data on ginkgo biloba for improving cognition in patients with dementia are more extensive than the data on prevention of cognitive impairment.
Omega 3 fatty acids: Some research shows eating fish reduces incidence of AD; omega 3 supplementation does not prevent AD; improved attention & processing speed with mild dementia (MD); does not improve cognition in AD.
Vitamin B12, B9: Some improvement in cognition in cognitively intact individuals but not those with dementia. Note that supplementation does not improve dementia in those with normal levels of Vitamin B, but if Vitamin B12 deficiency exists, supplementation can improve memory.
