1) What questions arise based on the study below regarding instability of sleep patterns in children with attention-deficit/hyperactivity disorder?

2)Are there other aspects that should be examined in order to study this further?

Objective: To compare the stability of the sleep-wake system of children with attention-deficit/hyperactivity disorder (ADHD) and controls by objective and subjective measures. Method: Thirty-eight school-age boys with diagnosed ADHD and 64 control school-age boys were examined using actigraphic monitoring and sleep diaries, over 5 consecutive nights. Results: Increased instability in sleep onset, sleep duration, and true sleep were found in the ADHD group compared with the control group. Discriminant analysis revealed that children’s classification (ADHD versus control) could be significantly predicted on the basis of their sleep measures. Conclusions: The findings support the hypothesis that instability of the sleep-wake system is a characteristic of children with ADHD. Given the potential negative effects of disturbed or unstable sleep on daytime functioning, it is recommended that a thorough sleep assessment be conducted when a sleep disturbance is suspected or when symptoms associated with daytime sleepiness or decreased arousal level are present

Solution

1.What methods were used to find sleep onset, sleep duration, and true sleep?

Why variations in number of control and test groups?

What are the objective and subjective measures used here?

2.Other symptoms should be evaluated such as restless leg syndrome.Researchers compared adults with narcolepsy, idiopathichypersomnia, and AHDH and found a high percentage of symptom overlap, suggesting the possibility of ADHD misdiagnosis among adults.This should be confirmed.ADHD is linked with emotional problems, higher rates of drug and alcohol abuse, and poor performance at school and work. he cause of ADHD is not known but experts suspect that it may be related to anatomic abnormalities in the brain, maternal smoking, exposure to toxins, and/or genetic factors.This all can be evaluated.
