Thirty-two epileptic patients with RDC diagnoses of schizophrenia were tested for handedness on the Annett Handedness Schedule, and handedness was assigned on the basis of Annett-Maudsley criteria. They were compared with three other groups of patients. Five (15.6%) of the epileptic schizophrenic patients were mixed or left handed. The prevalence of mixed and left handedness did not differ between the samples studied. However, there was a significant reduction of mixed and left handedness in male epileptics with schizophrenia. Mixed or left handedness in male epileptics appears to be protective against the development of psychiatric illness in general.
对32名经研究诊断标准（RDC）诊断为精神分裂症的癫痫患者，采用安妮特利手性量表测试其利手情况，并根据安妮特-莫兹利标准确定利手类型。将他们与其他三组患者进行比较。32名癫痫性精神分裂症患者中有5名（15.6%）为混合利手或左利手。所研究样本中混合利手和左利手的患病率无差异。然而，男性癫痫性精神分裂症患者中混合利手和左利手的比例显著降低。男性癫痫患者中的混合利手或左利手似乎总体上对精神疾病的发生有保护作用。
