Dyskinesia

Dyskinesia is a medical condition characterized by involuntary movements. These movements can be anything from quick, jerking actions (chorea) to longer, fluid movements (athetosis). Dyskinesia is often a side effect of treatment for Parkinson's disease.

Causes

Dyskinesia is most commonly caused by medications used to treat Parkinson's disease, specifically levodopa. Other causes can include other medications, such as antipsychotics, and certain medical conditions, such as Huntington's disease and Wilson's disease.

Symptoms

The symptoms of dyskinesia can vary greatly from person to person. They can include:

• Chorea: Quick, jerking movements
• Athetosis: Longer, fluid movements
• Dystonia: Muscle contractions that cause twisting and repetitive movements or abnormal postures
• Myoclonus: Sudden muscle spasms
• Tardive dyskinesia: Involuntary movements, especially of the lower face

Treatment

Treatment for dyskinesia is primarily focused on adjusting the medication that is causing the symptoms. This can involve reducing the dosage or switching to a different medication. In some cases, additional medications may be prescribed to help control the symptoms.
