Ataxia telangiectasia is a medical condition that affects a number of different organs in the body, including the brain. Ataxia telangiectasia causes the immune system to break down, increasing the chances for infection. Currently, there is no cure for ataxia telangiectasia and there is no way to slow the progression of the disease. Therefore, treatment for ataxia telangiectasia involves treating the symptoms of ataxia telangiectasia. Unfortunately, most people with ataxia telangiectasia die before the age of twenty.
