Mental disorders due to known physiological conditions (F01-F09)

This block comprises a range of mental disorders grouped together on the basis of their having in common a demonstrable etiology in cerebral disease, brain injury, or other insult leading to cerebral dysfunction. The dysfunction may be primary, as in diseases, injuries, and insults that affect the brain directly and selectively; or secondary, as in systemic diseases and disorders that attack the brain only as one of the multiple organs or systems of the body that are involved.

Includes: arteriosclerotic dementia
Code first the underlying physiological condition or sequelae of cerebrovascular disease.
F01.5 Vascular dementia
F01.50 Vascular dementia without behavioral disturbance
F01.51 Vascular dementia with behavioral disturbance
Vascular dementia with aggressive behavior
Vascular dementia with combative behavior
