What is characterized by irregular, jerky movements often caused by neuroleptic medication?

Tardive Dyskinesia is characterized by irregular, involuntary movements, particularly in the face and extremities, that often arise as a side effect of long-term use of neuroleptic medications (antipsychotics). These movements can include repetitive facial grimacing, tongue thrusting, and rapid limb movements. The condition is a result of neuroleptic-induced changes in the nervous system, particularly due to dopamine receptor sensitivity alterations.

This condition specifically highlights the impact of neuroleptics on motor control and is distinct from other movement disorders. Bradykinesia refers to slowness of movement and is more associated with conditions like Parkinson's disease. Parkinsonism encompasses a broader range of Parkinson's disease symptoms, which may include tremors, rigidity, and bradykinesia. Extrapyramidal Symptoms is a general term that includes various movement disorders caused by antipsychotic medications; however, it encompasses more beyond just the involuntary movements seen in tardive dyskinesia. Thus, tardive dyskinesia is the most accurate choice for describing the irregular, jerky movements linked specifically to neuroleptic medication use.
