○ Extrapyramidal symptoms (EPS) are motor symptoms associated with
antipsychotic drugs. Tardive dyskinesia (TD) is an EPS that usually appear after
prolonged treatment. TD consists of involuntary tonic muscular spasms of the
face and jaw. TD is most frequently seen in older women and patients and varies
from mild to moderate. It can be disfiguring or incapacitating.
○ Early symptoms of TD are fasciculations (very tiny involuntary motor movements)
of the tongue or constant lip-smacking. These early oral movements can develop
into uncontrollable biting, chewing, or sucking motions and lateral movements of
the jaw.
○ Delusions: thought broadcasting, thought insertion, thought withdrawal and being
controlled.
○ Concrete thinking: associated looseness, neologism, clan association, and word
