Eye blink and schizophrenia: psychosis or tardive dyskinesia?
JR Stevens
The author found abnormalities of ocular movement including abnormal blink
rate and blink reflex to glabellar tap in 34 of 44 medication- free
schizophrenic patients. It is not clear whether these signs represent part
of the pathology of schizophrenia or result from withdrawal of neuroleptic
treatment.
