Spinocerebellar Ataxia Type 28: Causes, Symptoms, and Treatment
Medically reviewed by Harsha Moole, MD, Internal Medicine. Last reviewed: October 2, 2026.
What kind of doctor treats Spinocerebellar Ataxia Type 28?
A neurologist, a doctor who treats brain and nerve conditions, usually leads care. A gastroenterologist helps when swallowing or digestion is affected. Physical, speech, and occupational therapists round out the team, and a primary care doctor often coordinates visits. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What it is
Spinocerebellar ataxia type 28 is a rare genetic disease that affects the cerebellum, the part of the brain that controls balance and movement. The word ataxia means a loss of muscle control that makes movements clumsy or unsteady. It usually develops slowly over many years, often beginning with mild clumsiness in adulthood, and how fast it changes differs from person to person.
Symptoms
The most common sign is trouble with balance and walking. A person may sway, stagger, or feel unsteady. Speech can become slow or slurred, a problem doctors call dysarthria, meaning difficulty forming words because the muscles used for talking are not coordinated.
Causes and who gets it
This condition is caused by a change in a gene called AFG3L2, inherited from one parent. It follows a dominant pattern, meaning a child of a parent who carries the changed gene has a one in two chance of getting it. Symptoms most often begin in early adulthood.
How doctors diagnose it
A neurologist starts with a physical exam, a review of symptoms, and a family history. Genetic testing can confirm the diagnosis by finding the changed gene. Brain scans and balance tests may be used to rule out other causes of ataxia.
Treatment
There is no cure, but a care team can help manage symptoms. Physical therapy can improve balance and strength, and speech therapy can help with talking and swallowing. When swallowing becomes difficult, a gastroenterologist may evaluate the esophagus and recommend safer ways to eat and drink.
When to see a doctor
Anyone with ongoing unsteadiness, slurred speech, or frequent falls should see a doctor. Early evaluation helps rule out treatable causes and connects people with the right specialists. Sudden balance loss, trouble swallowing, or choking while eating needs prompt medical attention.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. Either one can manage everyday care, including checkups, labs, and referrals, and will refer the patient to a neurologist or gastroenterologist when symptoms point to this condition.
Common questions
Is spinocerebellar ataxia type 28 fatal?
It is a serious lifelong condition, but it usually progresses slowly over decades. Life span depends on many factors, and results differ from person to person.
Can it be passed to my children?
Yes, each child of a parent who carries the changed gene has a one in two chance of inheriting it. A genetic counselor can explain testing options before or during a pregnancy.
Why is a stomach doctor involved?
When ataxia affects the muscles used for swallowing, food can go down the wrong way. A gastroenterologist checks the swallowing tube and helps make eating safer.
Is there a cure?
No cure exists today, but therapies can ease symptoms and help people stay independent longer. Research on genetic ataxias is ongoing.
