Drug-induced movement disorders come in different forms and can be caused by a number of medications that alter brain chemistry. The types of drugs most commonly associated with causing movement disorders are dopamine blocking medications (i.e. dopamine antagonist or antidopaminergic medications), which block a chemical in the brain called dopamine. This category of drugs includes antipsychotics that block dopamine. Dopamine blocking drugs can cause a variety of movement disorders including parkinsonism, tardive syndromes, chorea, dystonia, tremor, akathisia, myoclonus, tics, and a very serious condition called neuroleptic malignant syndrome. Movement symptoms may be focal to a specific body part, affect one side of the body, or be generalized throughout the body. Drug-induced movement disorders can sometimes, but not always, be relieved by stopping the offending drug. As is the case with additional movement disorders, anxiety and depression exacerbate symptoms.
