You have been referred to the Autonomic Unit at the National Hospital for Neurology and Neurosurgery (NHNN). This leaflet has been written by the Autonomic Unit for patients, their family or carers to provide information about the department and what you can expect from our service.

The Autonomic Unit

The Autonomic Unit comprises a multi- disciplinary team of consultants, nurse specialists, scientists, administrators and secretaries.

The focus is on the cardiovascular and sudomotor systems with close links to other relevant specialities within UCLH. The Unit investigates cardiovascular autonomic responses to postural changes and other key stimuli that we are all subjected to in daily life (such as food and exercise), and sudomotor (sweat gland) responses to physiological stimuli.

Which disorders do you treat?

We provide a comprehensive national tertiary clinical service (combining both investigation and management) for a wide variety of autonomic disorders. The Unit enables people with autonomic symptoms, some of which are multiple and complex, to manage their daily lives. Some examples are:

  • Pure Autonomic Failure
  • Autonomic dysfunction complicating Parkinson’s disease
  • Multiple System Atrophy (MSA)
  • Sweating dysfunction (including hyperhidrosis and anhidrosis)
  • Holmes-Adie Syndrome, Harlequin’s Syndrome
  • Autonomic dysfunction in spinal cord injury including autonomic dysreflexia
  • Neurally mediated syncope
  • Postural tachycardia syndrome (PoTS)
  • Autonomic diabetic neuropathy

Your care pathway

  • Initial consultation with consultant or specialist registrar, during which you can raise any queries you may have.
  • Autonomic testing with clinical autonomic scientists.
  • Follow-up appointment to decide on next steps.
