Abstract

Numerous studies have showed that the cerebellum has a role in processing higher brain functions besides motor coordination. Various types of congenital lesions of cerebellum are associated with neuropsychological impairments and behavioral changes. In Chiari malformation, the cerebellar structures have been stuck in posterior fossa. In this paper a case of Chiari malformation, presenting with affective instability and behavioral disinhibition was described.

Key words: cerebellum, affect, behavior, Chiari malformation
