  • Dysautonomia is a term used

    to describe abnormal functioning of

    the autonomic nervous system

    Dysautonomia means dysregulation of the autonomic nervous system. 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.

    Symptoms are wide ranging and can include problems with the regulation of heart rate, blood pressure, body temperature and perspiration. Other symptoms include fatigue, lightheadedness, feeling faint or passing out (syncope), weakness and cognitive impairment. 

    Autonomic dysfunction can occur as a secondary condition of another disease process, like diabetes, or as a primary disorder where the autonomic nervous system is the only system impacted. These conditions are often misdiagnosed.

    Over one million Americans are impacted with a primary autonomic system disorder. The more common forms of these conditions include Postural Orthostatic Tachycardia Syndrome (POTS) / Orthostatic Intolerance (OI), Neurocardiogenic Syncope (NCS), Pure Autonomic Failure (PAF) and Multiple Systems Atrophy (MSA)

    DINET provides information and personal stories on several types of dysautonomia. You may download our informational brochure HERE.

    The ENCHANT Study:  Electrographic and Neurohormonal Characteristics of Adolescent Nausea during Tilt-table testing

    Description:  Nausea is common with orthostatic intolerance. Our case-control story measures how stomach electrical activity changes in relation to various serum hormones during tilt-induced syncope. Study participants will undergo tilt-table testing with electrogastrography (EGG), electroencephalography (EEG), quantitative sweat, serial saliva samples, and IV placement for serial blood draws. All research testing is performed at Nationwide Children's Hospital, Columbus, Ohio.

    Particpation Requirements: We are recruiting cases and controls. Healthy control subjects will be paid ($200) for their participation. Cases are recruited directly from clinic referrals and will not be paid, but we will share testing results with all patients who participate. Our study does not cover any costs related to travel or lodging or any costs associated with clinic referral or medical care.

    Eligibility criteria for all participants:

    1. Age 12-21 years

    2. Body-mass index 18.5-25 kg/m2

    3. Normal cardiac exam

    Contol subjects must be in good general health and free of dizziness/lightheadedness, syncope, chronic nausea, anxiety, depression, and chronic medications.

    We are currently recruiting patients with syncope who do not have chronic or frequent gastrointestinal complaints such as nausea. We will be recruiting patients with syncope who do have chronic gastrointestinal complaints in near-future. All medicines that can affect tilt-table results or gastrointestinal function will be held at least 5 days prior to testing.
