EEG and a hand-eye functional asymmetry (FAS) profile have been compared in children with general speech retardation (GSR, 45 cases) and in normal children (45 cases) aged 5-7 years. The least EEG deviations have been noted in healthy full right-handed cases. Some delay in EEG maturation as well as existence of pathologic activity foci mostly in associative cortical brain areas have been noted in healthy non-right-handed and in GSR children. The most pronounced EEG disturbances have been observed in GSR children, 40% of whom were ambidextrous, left-handed and cross-lateralized children. The percentage of non-right-handed cases in the healthy group was less and decreased up to the age of 7 years. Prenatal, perinatal and 1st year postnatal pathology have been revealed in 86.6% of children in GSR group (in comparison to 11.1% in normal control group). Such pathology is suggested to be the reason of dysontogenesis and probably to be involved in brain electrical activity maturation, in FAS profile and in speech development.
对45例患有一般性语言发育迟缓（GSR）的儿童和45例5至7岁的正常儿童的脑电图（EEG）和手眼功能不对称（FAS）特征进行了比较。在健康的完全右利手儿童中，脑电图偏差最小。在健康的非右利手儿童和GSR儿童中，发现脑电图成熟存在一些延迟，并且病理活动灶主要存在于大脑联合皮质区域。在GSR儿童中观察到最明显的脑电图紊乱，其中40%是双手灵活、左利手和交叉偏侧化儿童。健康组中非右利手病例的百分比更低，且在7岁时有所下降。GSR组中86.6%的儿童存在产前、围产期和出生后第一年的病理情况（相比之下，正常对照组为11.1%）。这种病理情况被认为是发育异常的原因，可能与脑电活动成熟、FAS特征和语言发育有关。
