Dysautonomia is an umbrella medical term utilized for a group of complex conditions that are caused by a dysfunction of the autonomic nervous system (ANS). The ANS regulates all of the unconscious functions of the body, including the cardiovascular system, gastrointestinal system, metabolic system, and endocrine system. A dysfunction of the ANS can cause debilitating symptoms and may pose significant challenges for effective medical treatment.
Dysautonomia conditions can range from mild to extremely debilitating. Each dysautonomia case is unique and treatment must be individualized and may include pharmacological and non-pharmacological methods. Patients should be evaluated by a physician who is well-versed in the recent treatment modalities.
Orthostatic intolerance (the inability to remain upright) is a hallmark of the various forms of dysautonomia.
The following diagnostic terms may be issued to children with forms of dysautonomia:
- Postural Orthostatic Tachycardia Syndrome (POTS)
- Neurocardiogenic Syncope (NCS)
- Vasovagal Syncope
- Neurally Mediated Hypotension (NMH)
- Post-Viral Dysautonomia
- Familial Dysautonomia (FD)
- Non-Familial Dysautonomia
- Generalized Dysautonomia
Clinics are held each Monday morning at the UT Professional Building in the Texas Medical Center.
