Similarly, the extrapyramidal symptoms (EPS) reported by patients showed various movement disorders such as acute dystonic reactions and pseudoparkinsonism
which are usually managed with trihexyphenidyl and benztropine [61, 62].
The fifth chapter--Drug induced psychiatric disorders--enumerates and systematically describes the psychiatric disorders induced by psychotropic medication, including agitation, aggressiveness, psychotic symptoms, mania, hypomania, euphoria, suicidal behaviour, as well as movement disorders, such as pseudoparkinsonism
, akathisia, dystonia, dyskinezia, catatonia and, of course, the major emergency represented by neuroleptic malignant syndrome.
Types of antipsychotic-induced movement disorders include dystonias, akathisias, pseudoparkinsonism
, and tardive dyskinesia.
In a community-based study of 402 patients taking antiparkinsonian medication, the most common misdiagnoses were ET, Alzheimer's disease, and vascular pseudoparkinsonism
. (36) Moreover, many of the obvious features of PD--rigidity; gait disturbance, bradykinesia--can occur due to normal aging or from comorbid or multifactorial conditions (eg, diabetes, cancer).
First-generation ("conventional") antipsychotic agents are often associated with troubling extra-pyramidal symptoms (EPS), including pseudoparkinsonism
, erectile dysfunction, and tardive dyskinesia.
