Thiamin may be helpful to people with Alzheimer disease. It mimics acetylcholine, a neurotransmitter critical to memory. Alzheimer 's patients who take 3 to 8 g per day of thiamin have better mental function and fewer senility and memory problems. Any older adult with mental impairment may benefit from additional thiamin, too.

But deficiencies aren't common if you eat a varied diet of whole foods. Take a look at the thiamin values for the foods listed on the next page,
