Clinic
- AN or AAN is a form of polyneuropathy that affects the non-voluntary, non-sensory nervous system
- It affects mostly the internal organs such as the bladder muscles, the cardiovascular system, the digestive tract and genital organs.
- Autonomic nerve fibers form large collections in the thorax, abdomen, and pelvis outside the spinal cord.
- Most commonly autonomic neuropathy is seen in persons with long-standing Diabetes mellitus type 1 and 2
- Autonomic neuropathy is one cause of Dysautonomia
- Some conditions affecting the brain or spinal cord also may cause autonomic dysfunction, such as multiple system atrophy, and therefore, may cause similar symptoms to autonomic neuropathy.
Signs / Symptoms
- Urinary incontinence or Urinary retention: Neurogenic bladder is a broad term used to describe this dysfunction.
- Dysphagia, Abdominal pain, Nausea, Vomiting, Malabsorption, Fecal incontinence, Gastroparesis, Diarrhea, Constipation
- Disturbances of heart rate (Tachycardia, Bradycardia), Orthostatic hypotension, Inadequate increase of heart rate on exertion
- Central sleep apnea, Hypopnea, Bradypnea
- Pupillary defect, Exaggerated hippus, Dizziness or Light-headedness.
- Hypoglycemia unawareness
- Impotence
- Sicca: Sweat disturbances,
- Parkinsonian symptoms/ Multiple system atrophy
Causes
- Autoimmune disorders
- Diabetes, which is the most common cause of autonomic neuropathy, can gradually cause nerve damage throughout the body.
- Injury to nerves caused by surgery or radiation to the neck.
- Certain medications, including cancer chemotherapy.
- Amyloidosis, which affects nervous system.
- Neurodegenerative diseases including Parkinson's disease, MSA, Lewy body dementia and MS.
- Autoimmune autonomic ganglionopathy, sometimes as part of a paraneoplastic syndromes.
- Infections : Botulism, Lyme disease and HIV
- Inherited disorders. Certain hereditary disorders can cause autonomic neuropathy.
- Autoimmune diseases: Sjögren syndrome, SLE, RA, Celiac disease and Guillain–Barré syndrome
