A patient with postencephalitic chronic central hypoventilation and Parkinsonism is reported. The diagnosis was suspected because cyanosis, polycythæmia and respiratory acidosis were found in the absence of primary lung disease, obesity and involvement of the neuro‐muscular apparatus of respiration. Correction of the respiratory acidosis by voluntary hyperventilation and a diminished ventilatory response to the Inhalation of increased concentrations of carbon dioxide confirmed the diagnosis. Long‐term results of symptomatic therapy have been poor, creating a problem in management.
