The importance of the cerebellum in the coordination of movements has been known for many years. In recent years, data has been accumulating that some behavioral symptoms are observed in cerebellar disorders. Cognitive affective cerebellar syndrome, it presents primarily with cognitive dysfunctions including executive, language and visuospatial functions, as well as affective symptoms such as emotional blunting, passivity, personality changes, behavioral problems and rarely psychosis. Acute cerebellitis is an inflammatory condition characterized by acute onset cerebellar dysfunction. Cerebellitis can develop infectious, post-infectious, and post-vaccination. In this article, it is aimed to present a case of cerebellitis with cognitive affective cerebellar syndrome and psychosis findings. In our case, who had no known psychopathology, was admitted to the psychiatry service with the suspicion of conversion disorder due to the complaints of dizziness, nausea and gait imbalance that developed within hours after the psychogenic stressor factor. During her hospitalization, after the development of agitation, auditory-visual hallucinations, ataxia and dysarthria, cranial MRI with contrast showed hyperintense areas and edema in the bilateral cerebellar region, and a diagnosis of cerebellitis was made. Influence of non-motor cerebellar parts causes thought and emotional disorders and manifests as cerebellar cognitive affective syndrome. In our case, psychotic findings such as agitation and auditory-visual hallucinations after postinfectious cerebellitis, and cognitive symptoms such as impaired time-space orientation, weakened cooperation, childish speech and echolalia were observed. In conclusion, all these findings related to different areas due to cerebellar damage in this case indicates that the cerebellum participates in thought, affect, perception and cognition in the neural circuit model and supports the view that cerebellar dysfunction may underlie some neuropsychiatric symptoms.
