TY - JOUR PY - 2021// TI - Psychosis and Dandy-Walker syndrome: a case report and review of the literature JO - General psychiatry A1 - Porras Segovia, Alejandro A1 - Guerrero-Jiménez, Margarita A1 - Carrillo de Albornoz Calahorro, Carmen Maura A1 - Gutiérrez-Rojas, Luis SP - e100254 EP - e100254 VL - 34 IS - 2 N2 - Dandy-Walker syndrome (DWS) is a group of brain malformations which sometimes present with psychotic symptoms. We present the case of a patient diagnosed with Dandy-Walker variant who presented with schizophrenia-like psychosis. A man in his 30s was admitted to an acute psychiatric unit presenting with persecutory delusions, auditory hallucinations and violent behaviour. The MRI performed showed the typical alterations of Dandy-Walker variant: vermian hypoplasia and cystic dilatation of the fourth ventricle. He also suffered from mild intellectual disability. After being treated with olanzapine 10 mg/d for a month, his psychotic symptoms greatly improved and he was discharged. In conclusion, DWS may cause psychosis through a dysfunction in the circuit connecting prefrontal, thalamic and cerebellar areas. The association between these two conditions may contribute to the understanding of the aetiopathogenesis of schizophrenia.
