[Exogenous organic psychoses and their differential diagnosis in the forensic psychiatric clinic].

Forty-two male patients with organic involvement of the brain of various origins with different severity of psycho-organic changes were examined in order to detect the structural and dynamic clinical features of exogenous organic psychoses for forensic psychiatric expert evaluation. Four variants of such psychoses were distinguished (acute, protracted, relapsing, and periodical), depending on the conditions of development and syndrome formation. Their clinical manifestations are described, forensic psychiatric approaches defined, and variants of forensic psychiatric evaluation presented.
