作者检测了13例智力发育平均记分正常但运动发育迟缓的婴儿,结果发现其枕骨大孔(FM)的太小与呼吸机能障碍、躯体感觉诱发电位异常、运动发育迟缓有关。Polysomnogram(PSG)结果的异常与智能低下有关。软骨发育不全普遍形成侏儒状态,据报遣软骨发育不全患者智商低于80的占10～16%,超过一般群体预期值的9%。它表明在软骨发育不全患者中智能低下者较为普 The authors examined 13 infants with normal mean score points for mental retardation and motor stunting and found that too small an occipital foramen (FM) was associated with respiratory dysfunction, somatosensory evoked potentials, and impaired motor development. Abnormalities in Polysomnogram (PSG) results associated with mental retardation. Achondroplasia generally formed dwarf state, reported that patients with achondroplasia intelligence IQ less than 80 accounted for 10 to 16%, more than the general population expected value of 9%. It shows that in patients with achondroplasia is more common in patients with mental retardation
