In the DSM-5-TR®, Neurocognitive Disorders are a group of disorders in which the primary clinical deficit is in cognitive function and that are acquired rather than developmental; that is, impaired cognition has not been present since birth or very early life and thus represents a decline from a previously attained level of functioning (American Psychiatric Association, 2022).
(In DSM-IV, Neurocognitive Disorders were known as “Dementia, Delirium, Amnestic, and Other Cognitive Disorders.”)
The Neurocognitive Disorders in DSM-5-TR® are:
1. Delirium
2. Major Neurocognitive Disorder, and
3. Mild Neurocognitive Disorder.
The Major and Mild NCDs are subtyped according to etiology:
1. NCD due to Alzheimer’s disease
2. Vascular NCD
3. NCD with Lewy bodies
4. NCD due to Parkinson’s disease
5. Frontotemporal NCD
6. NCD due to traumatic brain injury
7. NCD due to HIV infection
8. Substance/medication-induced NCD
9. NCD due to Huntington’s disease
10. NCD due to prion disease
11. NCD due to another medical condition
12. NCD due to multiple etiologies
13. Unspecified NCD
