Dyskinesias refer to abnormal, involuntary movements that can result from various causes, such as neurological disorders, medication side effects, or brain injuries. These movements can range from mild twitching to severe, uncontrollable flailing of the limbs. Dyskinesias can impact a person's quality of life and ability to perform daily tasks. Treatment options may include medications, physical therapy, and in some cases, surgery. Research in this area aims to better understand the underlying mechanisms of dyskinesias, improve diagnostic methods, and develop more effective treatments to manage these symptoms.
