Nonlinear Z-score modeling for improved detection of cognitive abnormality

Alzheimer's & Dementia : Diagnosis, Assessment & Disease Monitoring

Dec 25, 2019

J KornakARTFL/LEFFTDS Consortium

Abstract

Conventional Z-scores are generated by subtracting the mean and dividing by the standard deviation. More recent methods linearly correct for age, sex, and education, so that these "adjusted" Z-scores better represent whether an individual's cognitive performance is abnormal. Extreme neg...read more

Corticobasal Degeneration

Corticobasal Degeneration (CBD)is a rare, neurodegenerative disease of the cerebral cortex and the basal ganglia, characterized by movement disorders. Discover the latest research on CBD here.

ALS & FTD: TDP-43

ALS shares with a considerable proportion of FTD cases the same neuropathological substrate, namely, inclusions of abnormally phosphorylated protein tdp-43 (ptdp-43). Here are the latest discoveries pertaining to ptdp-43 and these diseases.
