The Nithsdale schizophrenia survey: III. Handedness and tardive dyskinesia
RG McCreadie, J Crorie, ET Barron and GS Winslow
Handedness was assessed in 87 per cent (n = 116) of all known
schizophrenics from a discrete geographical area, Nithsdale in Dumfries and
Galloway Region. Seventy-three per cent were right-handed, a proportion
greater than that found in a normal population. It was especially Feighner
positive schizophrenics and non-in-patients who produced the excess of
right-handers. Within the Feighner positive group, 68 per cent of mixed or
left-handers, but only 29 per cent of right-handers, had tardive
dyskinesia.
