Ataxia-telangiectasia (A-T) is a rare, inherited disease. It affects the nervous system, immune system, and other body systems. Symptoms appear in young children, usually before age 5. They include
- Ataxia - trouble coordinating movements
- Poor balance
- Slurred speech
- Tiny, red spider veins, called telangiectasias, on the skin and eyes
- Lung infections
- Delayed physical and sexual development
People with A-T have an increased risk of developing diabetes and cancers, especially lymphoma and leukemia. Although it affects the brain, people with A-T usually have normal or high intelligence.
A-T has no cure. Treatments might improve some symptoms. They include injections to strengthen the immune system, physical and speech therapy, and high-dose vitamins.
