Numerous reports detail the multidirectional impact of sleep and ADHD on each other, and both sleep and ADHD related impairments may originate from common neurobiological pathways, reports Psychiatric Times.
The relationship between ADHD and sleep can be conceptualized as a bilateral comorbidity in which there is an increase in risk for the comorbid condition when either is present. Furthermore, ADHD and sleep disorders both contribute to the patient’s functional impairment, even though it is the ADHD that is most often the target of clinical attention.
This relationship is covered in great detail in the book
