The correlation between the delta and spindle components in compressed spectral array in 96 mentally retarded children (from 3 months to 12 years of age) was studied throughout nocturnal sleep. In 57 (59.4%, group A) of 96 subjects, periodic changes of delta and spindle rhythm powers were noted in sleep EEG. In 29 subjects (30.2% group B), delta but not spindle rhythm powers were found, and in the remaining 10 subjects (10.4%, group C) neither delta nor spindle rhythm powers were found throughout nocturnal sleep. A significant increase in abnormal clinical EEG was found in groups B and C as compared with group A. A significant decrease in the developmental quotient (DQ) was found in groups B and C as compared with group A. A significant decrease in DQ was also found in group C as compared with group B.
研究了96名智力发育迟缓儿童（年龄从3个月至12岁）夜间睡眠期间压缩谱阵中δ波和纺锤波成分之间的相关性。96名受试者中，57名（59.4%，A组）睡眠脑电图中出现了δ波和纺锤波节律功率的周期性变化。29名受试者（30.2%，B组）发现了δ波节律功率，但未发现纺锤波节律功率，其余10名受试者（10.4%，C组）在整个夜间睡眠中既未发现δ波节律功率也未发现纺锤波节律功率。与A组相比，B组和C组异常临床脑电图显著增加。与A组相比，B组和C组发育商（DQ）显著降低。与B组相比，C组DQ也显著降低。
