The onset of CNH in all patients regardless of age can be a precursor to ensuing deterioration in patients with infiltrative tumors of the brainstem and medulla. These patients experience prolonged series of CNH before succumbing to the associated deterioration of medullary cardiovascular center, which ultimately results in death. In addition to clinical consequences of a positive CNH diagnosis, sustained<unk>  also has a marked effect on daily life activities, and may significantly impede a patient’s ability to eat or talk. The persistent hypocarbia, alkalotic pH, and resultant electrolyte disequilibrium may also alter a patient’s mood or mental state. Patients presenting with CNH are often described as inattentive and anxious.
