The severity of symptoms associated with SCA6 varies, even within families. In most cases, symptoms develop in the forties or fifties and progress slowly. Over time, most individuals with SCA6 develop gait ataxia, loss of coordination in their arms, tremors, uncontrolled muscle tensing (dystonia), and dysarthria. Dysphagia and choking are also common. Cognitive function is generally preserved. Most people with this disorder require wheelchair assistance by the time they are in their sixties. Lifespan is not usually shortened by this disease.
