Medication-induced dyskinesias refer to abnormal involuntary movements that are caused or triggered by the use of certain medications. Dyskinesias are characterized by uncontrollable and involuntary muscle movements, which can range from slight tremors or twitching to more severe and disruptive gestures or postures. These movements can affect various parts of the body, including the limbs, face, tongue, and trunk.
These dyskinesias can occur as a side effect of certain medications, particularly those used in the treatment of neurological and psychiatric disorders. They are commonly associated with medications that affect the levels of dopamine in the brain, such as antipsychotic drugs used in the treatment of schizophrenia or medications for Parkinson's disease.
Medication-induced dyskinesias can manifest in different forms, including chorea (rapid, involuntary, and jerky movements), dystonia (sustained muscle contractions causing repetitive and twisting movements), athetosis (slow, twisting, and writhing movements), or tremors (rhythmic, involuntary shaking). These movements can be uncomfortable, impair daily activities, and have a significant impact on an individual's quality of life.
Management of medication-induced dyskinesias typically involves adjusting or modifying the medication regimen in order to alleviate or minimize the abnormal movements. This often requires a careful balance between symptom control and the potential side effects of reducing or discontinuing the causative medication. In some cases, additional medications may be prescribed to help manage the dyskinesias or alternative treatment options may be explored. Close monitoring and ongoing communication between the individual, their healthcare provider, and the care team are crucial for effectively managing medication-induced dyskinesias.
