Research Centers for Orthostatic Intolerance (OI) and Autonomic Disorders

Vanderbilt Autonomic Dysfunction Center

Mission - Autonomic disorders cause loss of regulation of the heart, blood vessels, stomach, bowel and bladder. Affected patients may have palpitations or lose consciousness, and some have a rapidly fatal course. We hope to join with patient support groups to harness the knowledge and energies of physicians and investigators in the major centers where these patients are cared for, so that they can discover ways to treat and to cure these diseases. The greater the collaboration between doctors and patients, the more we can learn about these disorders. This important first step is necessary if we are ever to find genuinely effective and curative treatments.

Postural Orthostatic Tachycardia Syndrome (POTS)

The Postural Tachycardia Syndrome (POTS): pathophysiology, diagnosis & management by Dr. Satish R. Raj

This article gives a good overview of the different types of Postural Orthostatic Tachycardia Syndrome (POTS) and potential treatments for each type. It's really important to work closely with a knowledgeable doctor on this.


Viral illness may spur 'standing up' disorder Dr. Raj is a co-author of this research study.

Wow; what an interesting development in POTS medical research!

Solve ME/CFS initiative (formerly The CFIDS Association of America)

Leading the Fight to Cure ME/CFS
Founded in 1987 and incorporated in North Carolina in 1990 as The Chronic Fatigue and Immune Dysfunction Syndrome (CFIDS) Association of America, the Solve ME/CFS Initiative (Solve M.E.) relocated to Los Angeles, CA and officially changed our name in 2014. Solve M.E. is a non-profit disease organization that works to accelerate the discovery of safe and effective treatments, strives for an aggressive expansion of funding for research that will lead to a cure and seeks to engage the entire ME/CFS community in research, advocacy, and patient support. Solve M.E. is the foundational ME/CFS organization, steadily broadening strategic, collaborative relationships with patients, researchers, government officials and other ME organizations across the globe.

Vertical Heterophoria

I included my experience with this on the Update page. I thought you might also be interested in additional information about Vertical Heterophoria to share with your doctors, too.

Vertical Heterophoria: New Discoveries Enable Treatment of Many Associated Disorders (on site)

Vision Specialists of Michigan - www.vision-specialists.com
Dr. Debby Feinberg specializes in the treatment of Vertical Heterophoria.

From the homepage - "The doctors at Vision Specialists of Michigan have made pioneering discoveries into the diagnosis and treatment of Vertical Heterophoria and Superior Oblique Palsy, two uncommonly recognized and poorly understood eye misalignment conditions. Those who suffer from Vertical Heterophoria or Superior Oblique Palsy tend to have a small amount of vertical eye misalignment, which the brain corrects by directing the eye muscles to properly reposition the eyes. However, using the eye muscles in this manner overworks them and they become strained and fatigued, causing the many symptoms of Vertical Heterophoria and Superior Oblique Palsy. The severity and number of symptoms vary from person to person - some people are much more affected than others. Traumatic Brain Injury (TBI) has been known to cause these symptoms.

Most patients experience a marked reduction in their symptoms with precise prismatic correction. The doctors at Vision Specialists of Michigan have developed a very detailed and specialized NeuroVisual Evaluation, which allows for the accurate diagnosis and treatment of Vertical Heterophoria and Superior Oblique Palsy. Using realigning prismatic spectacle lenses, the strain and fatigue within the visual system is reduced or eliminated. Patients notice significant improvement in their symptoms during their first office visit. Improvement continues over the course of several visits as the prismatic prescription is fine-tuned and customized for the individual.

A specialized Questionnaire has been developed by the researchers at Vision Specialists of Michigan to identify those who might be suffering from Vertical Heterophoria or Superior Oblique Palsy."

Vertical Heterophoria Questionnaire - www.vision-specialists.com/patients/bvd-questionnaire/

Dr. Debby Feinberg and her husband, Dr. Mark Rosner, have written a book - If The Walls of My Exam Room Could Talk - ad - about patients' experiences with Vertical Heterophoria.

Project Linus

Project Linus is a 100% volunteer non-profit organization with a two-fold mission:
First, it is our mission to provide love, a sense of security, warmth and comfort to children who are seriously ill, traumatized, or otherwise in need through the gifts of new, handmade blankets and afghans, lovingly created by volunteer "blanketeers."
Second, it is our mission to provide a rewarding and fun service opportunity for interested individuals and groups in local communities, for the benefit of children.
With chapters in all 50 states, Project Linus continues to grow. Blankets are collected locally and distributed to children in hospitals, shelters, social service agencies, or anywhere that a child might be in need of a big hug.
