Question

Quizplus · Accepted Answer

The distinction between major neurocognitive disorder (also known as dementia) and mild neurocognitive disorder is based on the degree of cognitive decline as compared to previous levels of performance. In major neurocognitive disorder, there is significant impairment in multiple cognitive domains that interferes with daily functioning and is a marked decline from previous levels of performance. In mild neurocognitive disorder, there is only a modest decline in cognitive functioning that does not interfere significantly with daily activities and is not as severe as major neurocognitive disorder. The other options (A, B, C) are not the basis for distinguishing between major and mild neurocognitive disorder.
