Dysautonomia literally means dysregulation of the autonomic nervous system. The autonomic nervous system is the master regulator of organ function throughout the body. It is involved in the control of heart rate, blood pressure, temperature, respiration, digestion and other vital functions. Dysregulation of the autonomic nervous system can produce the apparent malfunction of the organs it regulates. For this reason, dysautonomia patients often present with numerous, seemingly unrelated maladies.
DINET provides information and personal stories on several types of dysautonomia, with a focus on the following:
Postural Orthostatic Tachycardia Syndrome
The defining symptom of POTS is an excessive heart rate increment upon standing. However, as you will discover, there are a multitude of other symptoms that often accompany this syndrome. As such, POTS can be a difficult disorder to detect and understand.
Our web site provides an overview of POTS and contains sections on symptoms, mechanisms, causes, tests, myths, links and research. There are also sections with information on what may help or hinder POTS patients. To read more about postural orthostatic tachycardia syndrome, click on the links under the POTS Place category in the navigation bar to the left of this page.
Neurocardiogenic Syncope (NCS)
Our web site provides general information on NCS, and also explores its symptoms, mechanisms, diagnosis and treatment. A page full of links to other neurocardiogenic syncope resources on the Internet is included as well. To read more about neurocardiogenic syncope, click on the links under the NCS category in the navigation bar to the left of this page.
Pure Autonomic Failure (PAF)
Our web site provides a page full of links to pure autonomic failure resources on the Internet.
Multiple System Atrophy/Shy-Drager Syndrome (MSA)
Loss of balance, difficulty moving, loss of fine motor skills, muscle aches and pains, changes (decline) in facial expressions, difficulty chewing or swallowing and a mild decline in intellectual function are among other symptoms patients may experience. (MEDLINEPlus, 2003, Multiple System Atrophy).
MSA is a fatal illness, and patients usually die within ten years of onset.
Our website provides a page full of links to multiple system atrophy resources on the Internet.
The Dysautonomia Information Network also provides a support network for both dysautonomia patients and caregivers through the Meet Others Program. An online discussion forum is available for patients and caregivers as well.
When possible, cited information has been linked to the corresponding web site or Medline abstract. These links can be found in the reference section at the bottom of each page. Specific information can be located by using the "search" link, available under the DINET category in the links to the left of each page.
New information will continuously be added to this site as research evolves and new concepts emerge. The "What's New" page, available under the DINET category in the links to the left of each page, lists the latest additions to this web site.
