10 Unmissable Signs You Might Have Ataxia-Telangiectasia - No Doctor's Appointment Needed

4. Involuntary Movements

One of the most common forms of involuntary movements in ataxia-telangiectasia patients is abnormalities in the movements of the eyes. An affected individual may experience eye movements that are jerky and involuntary. Their eye movements may be rapid, repetitive, and rhythmic while moving in a circular, vertical, or horizontal direction. An individual affected by ataxia-telangiectasia may develop an involuntary tremor in their hands, which can cause problems when trying to use fine motor skills. The hand tremor may only be present when the patient is attempting to perform a task with their hands. The tremor may also be present or may only be present when they are at rest. The arms in affected individuals may make isolated but rapid movements that are involuntary and beyond their control. All of the involuntary movements that occur in ataxia-telangiectasia patients are the result of problems with the cerebellum and the basal ganglia in the brain.
