Sivarooban V, Yogitagavari Y, Che CK, Lee CW


Neuropsychiatric symptoms are symptoms that caused by organic brain disorders. Multiple neuropsychiatric symptoms can occur concurrently in the course of brain related organic disorders. Two main components of neuropsychiatric symptoms are cognitive impairment and disturbance of consciousness while other neuropsychiatric symptoms, such as hallucinations, delusions, mood disorders, anxiety, apathy, behavioural and personality changes also commonly occur. Some of the mild neuropsychiatric symptoms could possibly be the earliest manifestations of brain related organic disorders. Clinicians should carefully evaluate organic factors in the treatment of psychosis, especially in patients of very young age or older age. They should have enough knowledge and experience in the integrating neuroscience, that is, neuropsychiatry. The present report illustrates a case of organic disorder with neuropsychiatric manifestations. It is about a young male patient who was diagnosed with anti-NMDA receptor encephalitis and subsequently developed acute delirium secondary to the illness.
