OBJECTIVE: The aims of this study were to evaluate the sleep habits of @entity1 with @entity302 and to correlate @entity25 with @entity302 and level of intelligence. SUBJECTS AND METHODS: Twenty five subjects with @entity302 (14 males, age range 2-16.4 years) were recruited for this study. A control group was formed by 23 normal @entity1 . Two instruments to assess sleep habits were administered to the @entity1 with @entity302 : a questionnaire on sleep habits (to preschool @entity1 ) and a questionnaire on sleep behavior (for @entity1 aged more than seven years old); a cognitive test (Wechsler Intelligence Scale for @entity1 -WISC) was also performed. @entity1 underwent a complete @entity25 , including @entity9527 , were analyzed and correlated according to cognitive-behavioral measures in @entity1 with @entity302 . RESULTS: @entity1 with drug-resistant @entity302 and severe @entity1032 showed @entity25 such as @entity25 , high percentage of wakefulness after sleep onset, reduced slow wave sleep, and @entity25 . Sleep microstructure evaluated by means of @entity9527 analysis showed a decrease in A1 index during N3 in @entity1 with more severe @entity73 . @entity1 with @entity302 and @entity73 (n=10) had higher Sleep Behavior Questionnaire for @entity1 (SBQC) total scores (65.60    18.56) compared to @entity1 with @entity302 and normal IQ (50.00    10.40), p<0.05. CONCLUSIONS: @entity1 with drug-resistant @entity302 have a greater incidence of sleep problems regarding qualitative aspects, macrostructure, and @entity9527 . The decrease of @entity9527 rate and of A1, mainly during slow wave sleep (associated to REM sleep reduction), might represent a sleep microstructural pattern of @entity717 .
