Dysautonomia is the failure of the autonomic nervous system to adapt to stimuli or stress. Either the response is erratic, inappropriate in intensity, delayed in timing, or disconnected to the proper thermotome.
The failure of the autonomic nervous system has dramatic and devastating outcomes if not addressed and solved quickly. There are immediate consequences and long-term damages that take place when the sympathetic and parasympathetic branches of the autonomic nervous system are imbalanced and out of sync.
Dysautonomia or autonomic dysfunction is a condition in which the autonomic nervous system does not work properly. 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. A number of conditions can feature dysautonomia, such as Parkinson’s disease, multiple system atrophy, and dementia with Lewy bodies, Ehlers-Danlos syndromes, autoimmune autonomic ganglionopathy, and autonomic neuropathy, HIV/AIDS, autonomic failure, and postural orthostatic tachycardia syndrome.

Dysautonomia refers to a disorder of autonomic nervous system (ANS) function that generally involves failure of the sympathetic or parasympathetic components of the ANS, but dysautonomia involving excessive or overactive ANS actions also can occur. Dysautonomia can be local, as in reflex sympathetic dystrophy, or generalized, as in pure autonomic failure. It can be acute and reversible, as in Guillain-Barre syndrome, or chronic and progressive.
