Acesso em: 10 jun. 2021.2447-2573http://www.repositorio.ufop.br/jspui/handle/123456789/14134For many years, the cerebellum was thought to be only responsible for balance, movement, planning and execution. Nowadays, it is well accepted that most cerebellar connections are involved in non-mo tor functions. Herein, we provide a case report in which a 27-year- -old Brazilian male, diagnosed with Obsessive-Compulsive Disorder (OCD), has demonstrated cerebellar features that could be connec ted to Spinocerebellar ataxia type 1 (SCA-1), an autosomal dominant polyglutamine neurodegenerative disorder that had been previously ruled out. Since obsessive compulsive symptoms (OCS) are known to correlate with alterations in the cortico-striato-thalamo-cortical circuitry, we propose a possible association between OCS and SCA onset.en-USabertoSpinocerebellar ataxiasCerebellar disordersAtaxias espinocerebelaresDoenças cerebelaresArtigo publicado em periodicoEsta obra está sob uma licença Creative Commons Atribuição 4.0 Internacional (https://creativecommons.org/licenses/by/4.0/).
