New report on detecting Alzheimers in earlier stages
Robert Bazell reported on NBC Nightly News tonight about a new view of Alzheimer’s, as a three stage process. Stage 1 has few symptoms but lesions that could be seen with special tests. Stage 2 is “mild cognitive impairment”, or MCI, with about 5 million Americans affected. Stage 3 is major cognitive loss, again with 5 million Americans. Almost 15 million Americans are involved in giving care to Alzheimer’s patients.
One in eight people over 65 in the US have some Alzheimer’s symptoms, and 5% of cases start before 65, and there may be a different genetic explanation for early onset. The Mayo Clinic has a writeup on early onset here.
