About Autosomal Dominant Hereditary Ataxia

What is Autosomal Dominant Hereditary Ataxia?

Autosomal Dominant Hereditary Ataxia (ADHA) is a type of inherited neurological disorder that affects the coordination and balance of the body. It is caused by a mutation in a gene on one of the autosomes, which are the non-sex chromosomes. Symptoms of ADHA can include difficulty walking, clumsiness, poor coordination, and slurred speech. In some cases, the disorder can also cause vision and hearing problems.

What are the symptoms of Autosomal Dominant Hereditary Ataxia?

The symptoms of Autosomal Dominant Hereditary Ataxia can vary depending on the type of ataxia, but generally include:

-Loss of coordination and balance

-Difficulty walking

-Slurred speech

-Difficulty with fine motor skills


-Impaired vision

-Difficulty swallowing



-Memory loss

What are the causes of Autosomal Dominant Hereditary Ataxia?

The most common cause of Autosomal Dominant Hereditary Ataxia (ADHA) is a mutation in a gene called SCA1, SCA2, SCA3, SCA6, SCA7, SCA17, or DRPLA. Other causes include mutations in genes such as SACS, ATXN1, ATXN2, ATXN3, ATXN7, and ATXN10. Mutations in these genes can lead to a variety of neurological symptoms, including ataxia, which is the primary symptom of ADHA.

What are the treatments for Autosomal Dominant Hereditary Ataxia?

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 bathing.

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

4. Medications: Medications can help reduce symptoms, such as muscle spasms, tremors, and seizures.

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

6. Surgery: Surgery may be recommended to correct certain physical deformities.

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