[Diagnosis and forensic psychiatric expertise in traumatic cerebral arachnoiditis].

Patients (123) with traumatic cerebral arachnoiditis due to closed craniocerebral trauma, were investigated during complications or late sequelae of the trauma. All the patients were subjected to spinal puncture. Asthenic, psychosis-like and hallucinatory-paranoid disorders were detected as well as partial oligophrenia and dullness of consciousness. The degree of mental disorders run parallel with intracranial pressure elevation, suggesting the role of intracranial hypertension in pathogenesis of several psychic disorders.
