What are the 15 types of dysautonomia


Dysautonomia is an umbrella term for a group of medical conditions that affect the autonomic nervous system, responsible for regulating various involuntary bodily functions such as heart rate, blood pressure, digestion, and body temperature. There are several different types of dysautonomia, each with its own set of symptoms and underlying causes. Here are 15 types of dysautonomia, along with useful resource links for further information:

Dysautonomia is a complex medical condition affecting the autonomic nervous system. This article aims to elucidate the 15 distinct types of dysautonomia, shedding light on their unique characteristics, symptoms, and impact on individuals’ lives.

Understanding Dysautonomia

Dysautonomia is an umbrella term encompassing a range of disorders where the autonomic nervous system malfunctions. The autonomic nervous system controls automatic bodily functions, including heart rate, blood pressure, digestion, and more. When dysautonomia strikes, these essential functions are disrupted, leading to a myriad of symptoms.

Primary Types of Dysautonomia

  1. Postural Orthostatic Tachycardia Syndrome (POTS) POTS is characterized by an abnormal increase in heart rate when transitioning from a lying down to a standing position.
  2. Neurocardiogenic Syncope (NCS) NCS involves fainting or near-fainting episodes due to a drop in heart rate and blood pressure, usually triggered by standing.
  3. Multiple System Atrophy (MSA) MSA is a rare, progressive disorder affecting the autonomic nervous system, resulting in problems with movement and bodily functions.
  4. Pure Autonomic Failure (PAF) PAF involves failure of the autonomic nervous system, leading to various symptoms like dizziness, fainting, and bladder problems.
  5. Autoimmune Autonomic Ganglionopathy (AAG) AAG is an autoimmune disorder where the immune system mistakenly attacks the autonomic nervous system, causing dysautonomia symptoms.
  6. Familial Dysautonomia (FD) FD is a genetic disorder primarily affecting the autonomic nervous system, leading to symptoms such as difficulty swallowing, gastrointestinal issues, and unstable blood pressure.
  7. Hyperadrenergic POTS Hyperadrenergic POTS is a subtype characterized by an excess of norepinephrine in the body, resulting in heightened “fight or flight” responses.
  8. Mitochondrial Neurogastrointestinal Encephalopathy (MNGIE) MNGIE is a rare genetic disorder impacting mitochondrial function, causing gastrointestinal issues and neurological problems.
  9. Baroreflex Failure Baroreflex failure occurs when the baroreceptors, which regulate blood pressure, malfunction, leading to blood pressure fluctuations and related symptoms.
  10. Autoimmune Autonomic Small Fiber Neuropathy (AASFN) AASFN involves the immune system attacking the autonomic nervous system’s small nerve fibers, causing a range of autonomic dysfunctions.


  1. Is dysautonomia a common disorder?Dysautonomia is considered a rare disorder, but its exact prevalence is challenging to determine due to varying symptoms and diagnostic challenges.
  2. Is dysautonomia a lifelong condition?In many cases, dysautonomia is a chronic condition. However, the severity and progression of symptoms can vary from person to person.
  3. Is dysautonomia curable?Currently, dysautonomia is not curable, but its symptoms can be managed through lifestyle changes, medications, and other therapies.
  4. Can dysautonomia affect children?Yes, dysautonomia can affect individuals of all ages, including children and adolescents.
  5. Are there support groups for individuals with dysautonomia?Yes, several support groups and organizations provide resources, information, and support to individuals and families dealing with dysautonomia.
  6. What are the common symptoms of dysautonomia?Common symptoms of dysautonomia include dizziness, lightheadedness, fatigue, rapid heartbeat, excessive sweating, and digestive issues.
  7. Are there any known preventive measures for dysautonomia?Currently, there are no specific preventive measures for dysautonomia. However, leading a healthy lifestyle and managing underlying conditions may help in symptom management.


Dysautonomia encompasses a diverse array of conditions, each presenting unique challenges for those affected. By understanding these 15 types of dysautonomia and their distinct features, we can work towards better diagnosis, treatment, and support for individuals grappling with this complex disorder.
