Signs and Symptoms
Ondine's curse is associated with respiratory arrests during sleep and, with incomplete penetrance, to: neuroblastoma (tumors of the sympathetic ganglia), Hirschsprung disease (partial agenesis of the enteric nervous system), dysphagia (difficulty swallowing) and anomalies of the pupilla. Other symptoms include darkening of skin color from inadequate amounts of oxygen, drowsiness, fatigue, headaches, and an inability to sleep at night. Victims of Ondine's curse also suffer from a sensitivity to sedatives and narcotics which make respiration even more difficult for the patient. A low concentration of oxygen in the red blood cells also may cause high blood pressure culminating in cor pulmonale or a failure of the right side of the heart.

Famous quotes containing the words signs and/or symptoms:
“By nature servile, people attempt at first glance to find signs of good breeding in the appearance of those who occupy more exalted stations.”
—Anton Pavlovich Chekhov (1860–1904)
“A certain kind of rich man afflicted with the symptoms of moral dandyism sooner or later comes to the conclusion that it isn’t enough merely to make money. He feels obliged to hold views, to espouse causes and elect Presidents, to explain to a trembling world how and why the world went wrong. The spectacle is nearly always comic.”
—Lewis H. Lapham (b. 1935)
