What are the characteristics of spinocerebellar ataxia?

Spinocerebellar ataxia is the most common type of inherited ataxia. It is divided into several subtypes according to different genes, but the clinical manifestations are similar. Most of these patients show clinical manifestations in their 30s and 40s. The most common is bilateral lower limb ataxia. For example, patients walk shakily, step wide, and cannot change their pitch. They are presented with unstable walking of lower limbs and ataxia of upper limbs. Examination shows unstable finger nose test. This patient often needs genetic testing to confirm the diagnosis. There is no specific treatment for this disease. only symptomatic treatment, such as amantadine, can relieve symptoms. For patients with extrapyramidal system, levodopa can relieve symptoms, but the final treatment effect is poor. Most patients cannot walk for 10-20 years. Therefore, such patients must go to a regular hospital for genetic testing before they can finally be diagnosed.
