TL;DR
Both the manic-depressive and schizophrenic psychoses are characterized by a significant excess of left eye dominance and by an increasing divergence between eye and hand dominance when compared to the controls.
Abstract
A study of hand preference and eye dominance in schizophrenia, manic-depressive psychosis, and normal controls was carried out in the People's Republic of China. An excess of sinistrality was found in both men and women schizophrenics, but not in manic-depressive patients. Both the manic-depressive and schizophrenic psychoses are characterized by a significant excess of left eye dominance and by an increasing divergence between eye and hand dominance when compared to the controls. The major published studies investigating hand preference in psychopathology are reviewed, and possible interpretations of the conflicting findings are suggested.

No relationship was found between handedness and eye dominance either in the schizophrenic or the normal groups, which questions the assumption that eyedness-handedness nonconcordance is a pathological sign.

A small but significant shift towards left hand preference has been observed, more marked in the young patients and virtually confined to the males, which is discussed in relation to possible acquired abnormalities of functional brain organization.

A test of handedness in a sample of 20 autistic children and 25 normal children revealed marked differences, including the frequency of non-right-handedness in normal children, whereas it was 65% in autistic children.

A significant preponderance in the psychotic group of left‐handed patients, etiological factors and neurological signs reflecting organic damage, and seizures of automatic behaviour indicates that epileptic psychoses are caused by structural lesions affecting the deep parts of the temporal lobe.

Retrospective analysis of the psychiatric diagnoses in a group of patients surgically relieved of medically intractable epilepsy confirmed the hypothesis that patients with left-sided temporal lobe epileptogenic lesions are at greater risk for the development of a so-called schizophrenic-like psychosis and demonstrated an increased prevalence of sinistrals in the psychotic group.

There were no significant differences in structural asymmetry between the groups, but 8 left-handed schizophrenic patients may have had abnormal functional asymmetries; their mean ventricular-brain ratio, a possible indirect indicator of cerebral atrophy, was higher than that of the right-handed patients.

There was no significant difference in handedness between the two samples, but, contrary to some previous reports, excess of sinistrality was not associated with male sex, and the distribution of handedness was similar in neurotics and controls, but among psychotics in general there was a higher proportion of fully right-handed subjects.

The results support the hypothesis of a specific left hemispheric dysfunction in schizophrenia that is neither shared by all psychiatric patients nor resembles a generalized insult to the brain.

Evidence is presented indicating additional male/female contrasts in the incidence of birth complications, seasonality of birth, and birth order which support the hypothesis that the influence of gender on schizophrenia is a significant, transcultural phenomenon.

In contrast to normal children who display age-specific progressions of hand preference and lateral awareness, the schizophrenic boys showed no clear evidence of improvement in these abilities with increasing age, and disturbances in development may be considered to indicate the presence in schizophrenic children of primary central nervous system dysfunction.

A new series of patients with personality disorders has provided an opportunity to extend to both sexes an earlier finding that personality disordered women tend to be mixed handed, though deviations from consistent preference were small and dependent on the method used to classify handedness.

In patients of both sexes with continuous schizophrenia there were most frequent cases of lefthandedness, a left type of finger linkage and a left directing eye, and there were more males with a higher ridge on the left hand or equal ridges on both hands.
