X-linked spinocerebellar ataxia type 3 (SCA3) is a rare, inherited neurological disorder that affects the cerebellum, a part of the brain that controls movement and coordination. It is caused by a mutation in the ATXN3 gene, which is located on the X chromosome. Symptoms of SCA3 include difficulty walking, balance problems, slurred speech, and difficulty with fine motor skills. The disorder usually begins in childhood or adolescence and progresses over time. There is currently no cure for SCA3, but treatments are available to help manage symptoms.

The symptoms of X-linked spinocerebellar Ataxia type 3 (SCA3) vary from person to person, but may include:

- Unsteady gait

- Poor coordination

- Slurred speech

- Difficulty swallowing

- Muscle weakness

- Tremors

- Loss of balance

- Loss of fine motor skills

- Cognitive impairment

- Vision problems

- Hearing loss

- Seizures

- Abnormal eye movements

X-linked spinocerebellar ataxia type 3 (SCA3) is caused by a mutation in the ATXN3 gene. This gene provides instructions for making a protein called ataxin-3, which is involved in the development and maintenance of nerve cells in the brain and spinal cord. Mutations in the ATXN3 gene lead to an abnormally long version of the ataxin-3 protein, which disrupts the normal functioning of nerve cells and causes the signs and symptoms of SCA3.

1. Physical therapy: Physical therapy can help improve balance, coordination, and strength.

2. Occupational therapy: Occupational therapy can help with activities of daily living, such as dressing, eating, and writing.

3. Speech therapy: Speech therapy can help with communication and swallowing difficulties.

4. Medications: Medications can help reduce symptoms such as tremor, muscle spasms, and depression.

5. Assistive devices: Assistive devices such as walkers, canes, and wheelchairs can help with mobility.

6. Surgery: Surgery may be recommended in some cases to help improve mobility.

7. Genetic counseling: Genetic counseling can help families understand the condition and its inheritance pattern.

1. Being male
2. Having a family history of X-linked spinocerebellar ataxia type 3
3. Being of Ashkenazi Jewish descent
4. Having a mutation in the ATXN3 gene
5. Having a history of head trauma or stroke

At this time, there is no cure for X-linked spinocerebellar ataxia type 3 (SCA3). However, there are medications that can help manage the symptoms of the condition. These include medications to help with balance, coordination, and muscle control, as well as medications to help with anxiety and depression. Additionally, physical and occupational therapy can help improve coordination and balance.
