Psychiatric intensive care of dementia praecox.

33 year old British male's first presentation to mental health services was prompted by florid paranoid psychosis and volatile aggression. The patient developed agitated catatonia which eventually improved after 12 courses of ECT. The ongoing psychopharmacological management includes a second generation antipsychotic, a mood stabilizer antiepileptic and an anxiolytic. All investigations including blood tests, CSF analysis, urine and hair drug screen, CT and MRI scans with multidisciplinary medical consultations excluded any underlying pathology. The working diagnosis is an enduring paranoid psychosis with prominent signs of cognitive decline, all of which conclude to Kraepelin's Dementia Praecox.
