Description

Amyloid-beta and cognitive impairment for a sample of Catholic priests

Format

A data frame with 57 observations on the following 2 variables.

Group

mAD=Alzheimer's, MCI=mild impairment, NCI=no impairment

Abeta

Amount of Abeta from the posterior cingulate cortex (pmol/g tissue)

Details

Amyloid-beta (Abeta) is a protein fragment that has been linked to Alzheimer's disease. Autopsies from a sample of Catholic priests included measurements of Abeta (pmol/g tissue from the posterior cingulate cortex) from three groups: subjects who had exhibited no cognitive impairment before death, subjects who had exhibited mild cognitive impairment, and subjects who had mild to moderate Alzheimer's disease.
