Specifically, intensive postmortem neurological studies of their brain tissues reveal a relatively low density of acetylcholine (a neurotransmitter) nerve sites, which, at normal densities,
function in critical ways to help re-initiate breathing following a
sleep - related apnea or
extended breathing pauses.
In addition to biologically - based structures and networks described below that can shed light on the associations between inadequate
sleep and ADHD (as well as attention problems more broadly), adolescents with ADHD experience a host of functional impairments that often
extend to multiple domains of
functioning.
