Abstract
Objective To investigate the Video⁃Electroencephalography(VEEG)characteristics and abnormal rate among healthy elderly. Meth⁃ods According to the age,120 healthy elders were divided into groups A,B,and C. Group A has 57 subjects,aged 60⁃69 years old;group B has 42 people,aged 70⁃79 years;group C has 21 individuals,aged≥80 years. Chi square and Rank sum test were used to calculate abnormal rate of VEEG. Additionally,characteristics of alpha、slow wave and Iconic sleep wave were analyzed. Result The total abnormal rate of VEEG was 42.5%, and it was particularly high(76.2%)among elderly over 80s. Frequency,amplitude,reactivity of Alpha wave and alpha index decreased as age in⁃creased. Theta slow wave increased as age increased,abnormal frontal area theta showed an increase among elderly over 80 s. Each sleep cycle iconic sleep wave was gradually decreased in the elderly. No statistical difference was found about sleep spindles and vertex sharp among different groups . Positive occipital sharp transients of sleep(POSTS)decreased as age increased. There was no POSTS among elderly over 80 s. Conclusion Our re⁃sults showed that abnormal rate is increased in the elderly,while reactivity variation,slow alpha frequency,alpha amplitude,alpha index are de⁃creased. In addition,the slow waves in frontal area is increased,. sleep cycles becomes less distinct,and the typical wave are decreased.关键词
