“Our study does not support the treatment of individuals with mild to moderate Alzheimer’s disease and normal vitamin levels with B vitamin supplements,” the authors conclude.

This was interesting, and I wish I knew the dosages being used as well as the begining B12 levels of the study participants... but the real issue is that people with undiagnosed B12 deficiency can present with cogntive and dementia that mimics Alzheimer's disease.

This study included people with apparently normal levels of B12.

What constitutes "normal range" is a whole other issue... since labs lows are typically set aroud 150, yet neurological damage can occur with levels as high as 300-400 in some individuals.

In any case, anyone experiencing early symptoms of cognitive decline should be screened for B12 deficiency, and celiac disease as well! That hasn't changed with this study!
