akathisia symptoms what drugs cause it
Antipsychotics (also known as neuroleptics), particularly the first generation antipsychotics, may cause akathisia. Other known causes include side effects of certain medications, and nearly any physical dependence-inducing drug during drug withdrawal. It is also associated with Parkinson's disease and related syndromes.
These symptoms include dystonia (continuous spasms and muscle contractions), akathisia (motor restlessness), parkinsonism (characteristic symptoms such as rigidity), bradykinesia (slowness of movement), and tremor, and tardive dyskinesia (irregular, jerky movements).
