Q

What are the DSM5 criteria for MAJOR Neurocognitive Disorder?

A

A. SIGNIFICANT cognitive decline from previous level in one or more cognitive domains, based on: 1. Concern of the individual, a clinician, or a knowledgeable informant (aka family) 2. SUBSTANTIAL impairment in cognitive performance as determined by a domain test
