Mayo Clinic neurologists trained in autonomic neurology evaluate and treat people with autonomic disorders and offer detailed laboratory testing of autonomic function.

The autonomic nervous system is important for controlling automatic functions of your body, such as regulation of sweating, blood pressure, heart rate, digestion and sexual function.

People with autonomic problems may have many disabling symptoms, such as lightheadedness or fainting, constipation, bladder control problems, and sexual problems.

Conditions and symptoms

  • Adie syndrome
  • Anhidrosis
  • Autonomic failure
  • Autonomic neuropathy
  • Diabetic neuropathy
  • Dysautonomia or dysautonomic neuropathy

  • Multiple system atrophy
  • Neurocardiogenic syncope
  • Orthostatic hypotension (fainting)

Neurologists are active in clinical and basic science research to understand the cause of autonomic failure and to develop new treatments. Read about research in peripheral nerve disorders.
