Warning Signs Of Cerebellar Degeneration

Jerky Limb Movements

Individuals with cerebellar degeneration may experience jerky limb movements, which tend to be unsteady or slow. They're sometimes caused by dystonia, a disorder that causes uncontrollable muscle contractions. When the muscles contract, the body part involuntarily twists, which can lead to abnormal postures. Though dystonia might affect only one muscle, it typically affects multiple systems when associated with cerebellar degeneration. Common symptoms include cramping in the feet, pulling in the neck, uncontrolled blinking, and difficulty speaking. Fatigue and stress might make the symptoms worse.

Dystonia is related to the basal ganglia, the area of the brain located in the cerebrum that initiates muscle contractions. Dystonia typically presents in cases of cerebellar degeneration where other parts of the brain are also affected. In addition, jerky movements in the limbs can be a symptom of ataxia, which is a much more common symptom caused by dysfunction in the cerebellum.
