This diagnosis is a part of ICD10 collection.
- This refers to states of cerebral dysfunction associated with a disturbance in any of consciousness (like catatonia), cognition, mood, affect, and behavior in the absence of drugs, infection, or a metabolic cause. These usually are due to fixed, anatomic abnormalities, though these do not always show up on brain imaging.
- Thus, the "nonorganic" types are those due to drugs/substances, infection or metabolic causes, i.e. that they are (at least in principle) reversible.
