What is the outlook for individuals diagnosed with spinocerebellar ataxia type 6 (SCA6)?

The severity of symptoms associated with SCA6 varies, even within families. In most cases, symptoms develop in the forties or fifties and progress slowly.[1][2][3] Over time, most individuals with SCA6 develop gait ataxia, loss of coordination in their arms, tremors, uncontrolled muscle tensing (dystonia), and dysarthria.[1][3] Dysphagia and choking are also common. Cognitive function is generally preserved.[3] Most people with this disorder require wheelchair assistance by the time they are in their sixties.[1] Lifespan is not usually shortened by this disease.[2][3]
