ABSTRACT
In ICD-10, organic mental disorders are grouped on the basis of a common demonstrable aetiology being present in the form of cerebral disorder, injury to the brain, or other insult leading to cerebral dysfunction, which may be:
∑ primary – disorders, injuries and insults affecting the brain directly or with predilection, such as Alzheimer’s disease
∑ secondary – systemic disorders affecting the brain only in so far as it is one of the multiple organs or body systems involved (e.g. hypothyroidism).
