Factors associated with left-handedness were examined in a large sample of adults who suffered with epileptic seizures (n = 446) in an attempt to delineate the concept of pathological left-handedness. Three main pathological factors were found associated with left-handedness: (i) right-hemiparesis of early onset; (ii) cognitive deficit; (iii) evidence of left-hemisphere disease on clinical examination. Familial sinistrality was also associated with left-handedness, independently of the above-mentioned pathological factors. Results support a clear-cut distinction between normal and pathological left-handedness. This distinction seems presently important for the evaluation of the great number of anomalies proposed to be associated with left-handedness.
在一大群患有癫痫发作的成年人样本（n = 446）中，研究了与左利手相关的因素，以试图阐明病理性左利手的概念。发现与左利手相关的三个主要病理因素：（i）早发性右侧偏瘫；（ii）认知缺陷；（iii）临床检查中左半球疾病的证据。家族性左利手也与左利手相关，独立于上述病理因素。结果支持正常左利手和病理性左利手之间有明确的区分。目前，这种区分对于评估大量被认为与左利手相关的异常情况似乎很重要。
