• Fatigue

  The only symptom is excessive fatigue. Secondary hypersomnia is due to other medical conditions. These can include sleep apnea, Parkinson’s disease, kidney failure, and chronic fatigue syndrome. [healthline.com]

• Dysostosis

  Abstract Polysomnography and blood gas measurements during sleep in a young man with craniofacial dysostosis, who presented with an extremely severe sleep apnea syndrome, are reported. [ncbi.nlm.nih.gov]

• Kayser-Fleischer Ring

  Kayser-Fleischer ring was not detectable. D-penicillamine (DPA) was introduced. At 8-10 months after the initiation of the therapy the patient's complaints gradually resolved. [ncbi.nlm.nih.gov]

• Intermittent Slow Activity

  Electroencephalographic (EEG) background activity for this individual was slightly slowed in the EEG during an episode of hypersomnia, and intermittent slow activity was found in addition. [ncbi.nlm.nih.gov]

• Gliosis

  Severe neuronal loss and gliosis were observed in the midbrain and pontine raphe, particularly in dorsal raphe nucleus and superior central nucleus. Pontine and medullary reticular formation also showed a marked cell loss and fibrillary gliosis. [ncbi.nlm.nih.gov]

• HLA-DR1

  Both patients share the same HLA haplotype (HLA-DR1, DQ1) which has been found in Kleine-Levin syndrome. [ncbi.nlm.nih.gov]

Type and frequency of substance use were assessed at treatment entry. Substance use was also assessed 12 months following treatment completion. [ncbi.nlm.nih.gov]

The attacks usually continue indefinitely. x Prognosis The prognosis for persons with hypersomnia depends on the cause of the disorder. [ninds.nih.gov]

Referral to a sleep specialist is required in performing objective sleep studies, establishing the diagnosis, recommending treatment, and providing a prognosis. Many sleep disorders are treatable and aeromedically waiverable. [ncbi.nlm.nih.gov]

Prognosis The prognosis for persons with hypersomnia depends on the cause of the disorder. While the disorder itself is not life threatening, it can have serious consequences, such as automobile accidents caused by falling asleep while driving. [brainfacts.org]

Prognosis Hypersomnia can be chronic, especially when not associated with another disorder and therefore can continue to worsen if left untreated. Treatments are readily available and can improve the prognosis significantly. [allpsych.com]
