<unk>  is exhibited typically as a congenital disorder, but in rare circumstances, can also result from severe brain or spinal trauma or injury (such as after an automobile accident, stroke, asphyxiation, brain tumor, encephalitis, poisoning, as a complication of neurosurgery) or due to particular neurodegenerative conditions such as Parkinson's disease, multiple system atrophy, or multiple sclerosis. Long and Allen (1984) were the first to report the abnormal brainstem auditory evoked responses in an alcoholic woman who recovered from Ondine's curse. These investigators hypothesized that their patient's brainstem was poisoned — not destroyed — by her chronic alcoholism. Medical investigation of patients with this<unk>  has led to a deeper understanding of how the body and brain regulate breathing on a molecular level. PHOX2B, a transcription factor involved in the development of neurons, can be associated with this condition. This homeobox gene is important for the normal development of the autonomic nervous system. The disease used to be classified as a "neurocristopathy", or disease of the neural crest because part of the autonomic nervous system (such as sympathetic ganglia) derives from the neural crest. However, this denomination is no longer favored because essential neurons of the autonomic nervous system, including those that underlie the defining symptom of the disease (respiratory arrests), are derived from the neural tube (the medulla), not from the neural crest, although such mixed embryological origins are also true for most other neurocristopathies.
