A degenerative disease of the autonomic nervous system, symptoms include dizziness and fainting (caused by orthostatic hypotension), visual disturbances and neck pain. Chest pain, fatigue and sexual dysfunction are less common symptoms that may also occur. Symptoms are worse when standing; sometimes one may relieve symptoms by lying down. More pervasive autonomic dysfunction involving any of the following: night sweats or abnormal lack of sweating, urogenital problems (frequent UTIs, incontinence, frequency, urgency), gastrointestinal problems (chronic constipation, chronic constipation alternating with diarrhea, poor gastric motility), or esophageal/respiratory problems (sleep apnea, abnormal breath sounds during sleep or while awake) indicate possible autoimmune autonomic ganglionopathy or multiple system atrophy.
