Extrapyramidal side effects are seen with all first-generation, and most second-generation, antipsychotic drugs. Acute akathisia and acute dystonic reactions are usually the first extrapyramidal side effects to develop, primarily shortly after initiation of an antipsychotic or a dose increase, and generally before parkinsonism develops. Acute dystonic reactions consistently resolve when the offending drug is stopped, but akathisia has a more complex prognosis.

Positional vertigo is triggered by and occurs after a change of head position in space relative to gravity. The most common cause of positional vertigo is due to canalolithiasis of the labyrinth. Central positional vertigo should be suspected when features of nystagmus differ from those of benign paroxysmal positional vertigo, or when brainstem and cerebellar signs are present.

Although headache is almost always a biochemical disorder, psychological factors often play a contributory role in headache onset and/or a reactive role in headache maintenance. There is a high level of comorbidity between headache and psychiatric disorders such as depression and anxiety. Psychological interventions such as psychotherapy and biofeedback are not only useful adjuncts to medication therapy, but also permit patients to be actively involved in managing their lifestyles.
