The sad thing is that yearly sales dollars of Prevagen exceed yearly Dementia research funding by The National Institute of Health (NIH)
not that the total efforts of NIH since 1992 have resulted in a single “clinically useful” drug in the 6 that were eventually approved.

By “clinically useful” I mean 95% of caregivers notice a beneficial improvement in the patients behavior,
despite what standard tests on large numbers of patients show as mathematically “Statistically Significant” at the 95% confidence level.

Skip the Prevagen
do some sort of daily exercise,
daily eat more Extra Virgin olive oil to help your “Blood Brain Barrier”
and get more daily fiber in your diet so as to sleep better nightly.

It is not a hopeless situation
as the “Tau-ist” school of Dementia researchers are reporting encouraging results lately,
and the “BAP-ist” researchers are no longer hogging 90% of the grant money.
