Strong mixed-handedness in schizophrenia.
There is still considerable discussion of whether schizophrenia is a lateralized brain disorder. In fact, schizophrenic patients appear to exhibit a shift away from dexterity, as confirmed by the majority of the 23 publications dealing with this question (14 positive, seven null, two paradoxical). However, quite a few of these positive studies have distinguished between left-handedness and mixe...
متن کاملAsymmetries of cortical shape: Effects of handedness, sex and schizophrenia.
Some evidence suggests that sex, handedness and disease processes associated with schizophrenia affect the magnitude and/or direction of structural brain asymmetries. There are mixed findings, however, on how these factors influence cerebral torque, when torque is assessed with linear or volumetric measurements. We obtained MRI data from 67 healthy (30 males, 10 non-dextrals) and 84 schizophren...
متن کاملAtypical handedness in schizophrenia: some methodological and theoretical issues.
An updated review of the literature strongly supports the view that in schizophrenia there is an atypical leftward shift in the handedness distribution that, while comprising different subtypes, is characterized by a more variable and less completely lateralized pattern of manual preference, referred to as mixed handedness (MH) or ambiguous handedness (AH). Only two studies revealed an increase...
متن کاملAsymmetries of cortical thickness: effects of handedness, sex, and schizophrenia.
Sex, handedness, and disease processes in schizophrenia may affect the magnitude and/or direction of structural brain asymmetries. Using MRI data from 67 healthy (30 men, 10 nondextral) and 84 schizophrenia patients (60 men, 16 nondextral), cortical thickness asymmetries were compared at high spatial resolution. Within-group asymmetries were observed in sensorimotor, perisylvian, and parahippoc...
متن کاملParent-of-origin effects on handedness and schizophrenia susceptibility on chromosome 2p12-q11.
Schizophrenia and non-right-handedness are moderately associated, and both traits are often accompanied by abnormalities of asymmetrical brain morphology or function. We have found linkage previously of chromosome 2p12-q11 to a quantitative measure of handedness, and we have also found linkage of schizophrenia/schizoaffective disorder to this same chromosomal region in a separate study. Now, we...
