The symptoms of hypothyroidism are protean and include apathy, somnolence, lethargy, personality change, and intellectual deterioration. Many of these symptoms may be related to hypothyroid-induced sleep disorders. Hypothyroidism is associated with abnormal ventilatory drive, abnormal sleep architecture, and sleep apnea. Central, obstructive, and mixed patterns of sleep apnea are commonly observed in hypothyroidism. A case of severe sleep apnea in a grossly myxedematous patient who improved dramatically following thyroid replacement alone is presented. Myxedema is a reversible cause of sleep apnea, and thyroid function testing should be considered in its diagnostic work-up.

Acute autonomic and sensory neuropathy (AASN) is a rare neuropathy characterized by acute autonomic dysfunction and objective sensory disturbances. A 26-year-old pregnant woman with severe autonomic and sensory dysfunction is reported. This patient suddenly developed marked nausea and vomitting in about 2 days after having a sore throat. She then developed signs of autonomic dysfunction including dilated non-reactive pupils, dryness of the eyes and oral mucous membranes, generalized anhidrosis, paralytic ileus, orthostatic hypotension, and continuous tachycardia. She also had severe generalized sensory impairments of all modalities, and all deep tendon reflexes were absent. Sensation was almost totally lost for all modalities below the neck. There was marked pseudoathetosis and sensory ataxia in all extremities. Motor examination was normal. She had inability to urinate. At this time she was 38 weeks pregnant, and when she showed signs of fetal distress, a Caesarean section was performed. Albumino-cytological dissociation was seen in the CSF. Serum noradrenaline was reduced, no sensory nerve action potentials could be elicited, and reduced coefficient of variation of the R-R interval on electrocardiography was observed. Plasma exchange was performed every other day for 3 days for about 3 weeks after the onset of the illness, but no favorable effects. Seven months after the onset, her autonomic dysfunction slightly improved, but there was no recovery from the sensory disturbances. Many symptoms and signs that characterize AASN occurred in this patient, and each was severe. The patient developed SIADH, sleep apnea, personality change, and amenorrhea in the course of the disease. We suggest that AASN patients might have both peripheral and central nervous system manifestations including seizures and personality changes.
