Inherited from F01-F09Mental disorders due to known physiological conditions
Note

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.

Inherited from chapter 5Mental, Behavioral and Neurodevelopmental disorders
Includes

disorders of psychological development

Excludes 2

symptoms, signs and abnormal clinical laboratory findings, not elsewhere classified (R00-R99)
