I need a doctor that treats absence of slow wave sleep

I have had multiple sleep study tests that show I get no slow wave sleep even though I do not have sleep apnea, restless limb syndrome or narcolepsy. I also did the day time test in which you nap every two hours and the conclusion was that I am chronically sleep deprived. Are there any doctors that can address this? Please note, I do not need help with sleep apnea, restless syndrome of narcolepsy as we have already ruled those issue out.

I’ve had 2 sleep studies and both showed severe Periodic Limb Movement Disorder. This is not Restless Leg Syndrome so I’m not aware of my leg twitches, as they only happen during sleep and do not wake me. PLMD could be preventing you slow wave sleep.
You sound like me. I fall asleep ok, sleep all night and wake up totally unrefreshed. I don’t have any of the more common sleep disorders.
Sleep Doctors don’t seem to want to help us much or engage in discussion on the subject of PLMD.
