There are several types of ataxia, including: ataxia telangiectasia (AT), episodic ataxia, Friedreich's ataxia, multiple system atrophy (MSA) and spinocerebellar ataxia. This condition happens when the part of the brain called the cerebellum is damaged. There is no cure for ataxia, but the symptoms can be treated
