Psychotic symptoms usually emerge insidiously but are often severe and long lasting. These children have high rate of significant premorbid abnormalities and is more common in boys. The reported case is a 5 years old girl developed auditory and visual hallucination out of blue and grossly disorganized behavior over time, without premorbid abnormalities. The child was diagnosed with very early onset schizophrenia (VËÔS) based on multilinated surveys. The patient responded well to risperidone. Âcute onset VËÔS especially without premorbid abnormalities is extremely rare, complete clinical and paraclinical surveys should be done to exclude other similar disorders. M3 ER -
