Dysautonomia or autonomic dysfunction is a condition in which the autonomic nervous system (ANS) does not work properly, that generally involves failure of the sympathetic or parasympathetic components of the ANS, but dysautonomia involving excessive or overactive ANS actions also can occur. This may affect the functioning of the heart, bladder, intestines, sweat glands, pupils, and blood vessels. Dysautonomia has many causes, not all of which may be classified as neuropathic. Dysautonomia also can occur as a primary condition or in association with degenerative neurological diseases such as Parkinsons disease. The primary symptoms in individuals with dysautonomia include: Anhydrosis, Anxiety, Blurry or double vision, Bowel incontinence, Brain fog, Constipation, Dizziness Difficulty swallowing, Exercise intolerance, Chronic fatigue and Insomnia.
Some of the different forms of dysautonomia include:
1. Postural Orthostatic Tachycardia Syndrome (POTS)
2. Neurocardiogenic Syncope (NCS)
3. Multiple System Atrophy (MSA)
