Spinocerebellar Ataxia

11 min read

Spinocerebellar ataxia (SCA) is a group of inherited neurological disorders that affect balance, coordination, and speech. It is caused by degeneration of the cerebellum, a part of the brain that controls movement. SCA is a progressive disorder, meaning that symptoms worsen over time. It is estimated to affect more than 150,000 people in the United States.

Causes of Spinocerebellar Ataxia

SCA is caused by a genetic mutation that affects the production of proteins in the brain. These mutations can be inherited from a parent or can occur spontaneously. SCA is classified into several types, depending on the gene that is affected and the type of mutation.

Diagnosis of Spinocerebellar Ataxia

SCA is usually diagnosed through a physical exam and a neurological exam. Other tests, such as genetic testing, imaging studies, and blood tests, may also be used to confirm the diagnosis. A doctor may also ask about family history to determine if the disorder is inherited.

Complications of Spinocerebellar Ataxia

SCA can cause a variety of complications, including difficulty walking, speaking, and swallowing. It can also lead to depression, anxiety, and other mental health issues. People with SCA may also be at risk for falls and other injuries.

Living with Spinocerebellar Ataxia

Living with SCA can be challenging, but there are ways to manage the condition. Physical and occupational therapy can help improve balance and coordination. Assistive devices, such as walkers and wheelchairs, can also help with mobility. Additionally, medications and other treatments can help manage symptoms and slow the progression of the disorder.
