Sleep Disorders

Central alveolar hypoventilation

Central alveolar hypoventilation, a disorder of impaired ventilatory response to hypercapnia and hypoxemia, may be congenital, acquired, or idiopathic. The underlying neurologic disorder involves an absent or reduced response to carbon dioxide resulting in hypercapnia and hypoxemia. Patients exhibit hypoventilation, which is generally worsened in sleep, and they may also suffer from varying degrees of dysautonomia.

Sleep Disorders

Idiopathic hypersomnia

The main symptom of idiopathic hypersomnia is an irresistible urge to sleep despite adequate, or even excessive, nocturnal sleep, which lasts at least 3 months. Idiopathic hypersomnia can be associated with symptoms of autonomic nervous system dysregulation (orthostatic hypotension, syncope, headache, and Raynaud-type phenomena) and with significant sleep inertia. The cause of idiopathic hypersomnia remains unknown, but it is likely to be composed of several distinct disorders.
