The following list includes some of them:

Bruxism, involuntary grinding or clenching of the teeth while sleeping
Catathrenia, nocturnal groaning during prolonged exhalation
Delayed sleep phase disorder (DSPD), inability to awaken and fall asleep at socially acceptable times but no problem with sleep maintenance, a disorder of circadian rhythms. Other such disorders are advanced sleep phase disorder (ASPD), non-24-hour sleep–wake disorder (non-24) in the sighted or in the blind, and irregular sleep wake rhythm, all much less common than DSPD, as well as the situational shift work sleep disorder. Fatal familial insomnia, an extremely rare prion disease that causes a complete cessation of sleep, leading quickly to death by sleep deprivation. Hypopnea syndrome, abnormally shallow breathing or slow respiratory rate while sleeping
Idiopathic hypersomnia, a primary, neurologic cause of long-sleeping, sharing many similarities with narcolepsy
Insomnia disorder (primary insomnia), chronic difficulty in falling asleep and/or maintaining sleep when no other cause is found for these symptoms. Insomnia can also be comorbid with or secondary to other disorders. Kleine–Levin syndrome, a rare disorder characterized by persistent episodic hypersomnia and cognitive or mood changes
Narcolepsy, characterized by excessive daytime sleepiness (EDS) and so-called "sleep attacks," relatively sudden-onset, irresistible urges to sleep, which may interfere with occupational and social commitments. About 70% of those who have narcolepsy also have cataplexy, a sudden weakness in the motor muscles that can result in collapse to the floor while retaining full conscious awareness.

Periosteal reaction along the shaft of the tibia. It can result from congenital syphilis, yaws, Pagets disease of bone, vitamin D deficiency or Weismann-Netter–Stuhl syndrome. It can be due to osteomalacia. Prognosis
