We describe a patient with olivopontocerebellar atrophy (OPCA) who was referred for alleged "snoring." Polysomnogram with video and audio monitoring revealed that the patient actually had nocturnal stridor causing repetitive oxygen desaturations. Direct laryngoscopy while awake showed a unilateral vocal cord paralysis. The nocturnal stridor persisted after unilateral vocal cord pinning, suggesting that the patient had probably been experiencing bilateral vocal cord paresis while asleep. We conclude that state-dependent vocal cord dysfunction may be severe in OPCA and related multiple system atrophy. Nocturnal stridor has many causes and may mimic snoring and obstructive sleep apnea syndrome. Polysomnography with audio and video recordings are necessary to make the diagnosis.

We reported an autopsy case of hereditary OPCA genetically proved to be SCA 1. Clinically, he showed cerebellar ataxia from beginning to the end stage, and was characterized by slow eye movement with external ophthalmoplegia, pyramidal tract signs, generalized amyotrophy including facial muscle, mild bulbar paresis, mild dementia, and urinary disturbance. Neuropathologically, the degeneration and loss of neurons with gliosis were seen in the Purkinje layer, dentate nucleus of the cerebellum, inferior Olive nucleus, motor nucleus of cranial nerve, anterior horn of the spinal cord, and column of the Clarke. And the myelinpallor was revealed in the connecting nerve fiber of these lesions, posterior column and spinocerebellar tract of the spinal cord.

Prognosis of 21 patients with multiple system atrophy (MSA) who deceased or received tracheostomy is described. The percentage of patients with MSA among the cases of spinocerebellar degeneration was 40% in National Tokyo Hospital. There were 12 women and 9 men, and the mean age at onset was 56 years. Seventy-four percent of MSA patients was olivopontocerebellar atrophy (OPCA), 22% was striatonigral degeneration (SND). The mean age of 17 deceased patients (10 women, and 7 men) was 65.5 years. Ten patients did not undergo tracheostomy and deceased, and 11 patients underwent tracheostomy, among whom 4 patients are still alive. Mean duration of illness from onset to death (without tracheostomy) or tracheostomy was 6.8 years. Cause of death of patients who did not undergo tracheostomy was related to paresis of the larynx or pharynx, for example, aspiration pneumonia due to dysphagia, vocal cord paralysis and sudden death. Some of those who underwent tracheostomy deceased for causes which were not directly related to MSA such as cerebral hemorrhage or uremia, but others seem to be related to some problems of respiratory center such as central chronic respiratory failure, or sudden death (sometimes it happened after infection, but the obstruction of the respiratory tract was not always present at autopsy).
