				        	 Spinocerebellar ataxia type 2 (SCA2) is an autosomal dominant degenerative disease. The main clinical manifestation of SCA2 is progressive cerebellar syndrome, but a wide range of extracerebellar and non-motor symptoms can be observed clinically. The non-motor symptoms and extra-cerebellar signs in SCA2 patients are reviewed to provide a better understanding in cognition, diagnosis and treatment of the disease.
