medication-induced movement disorder
Abnormal involuntary movements caused by psychotropic medications, including tremor, dystonia, and tardive syndromes.
Full Definition
Medication-induced movement disorders encompass a range of abnormal motor symptoms that develop as adverse effects of psychotropic medications, particularly antipsychotics and certain antidepressants. These disorders include acute dystonia, parkinsonism, akathisia, tardive dyskinesia, and tardive dystonia. The onset can be acute (within hours to days) or delayed (months to years after initiation). Proper documentation requires careful temporal relationship establishment between medication exposure and symptom onset, as well as detailed description of the specific movement abnormalities observed. Recognition is crucial for clinical editors as these conditions significantly impact treatment decisions and patient safety.
Usage
Usage note: Specify the type of movement disorder and temporal relationship to medication; distinguish from primary neurological conditions.
