 This link talks about ADHD. Essentially, a symptom of ADHD is excessive daytime sleepiness (EDS). This is caused partly by poor sleep. A symptom of OSA is EDS also. It is estimated that about 25% of ADHD diagnoses are related to sleep disorders. Also it is reported that those with ADHD are three times more likely to have habitual snoring. This correlation further shows that many ADHD diagnoses are related to sleep disorders such as OSA which helps prove your statistic that sleep apnea is misdiagnosed was ADHD.
