In 2010 while at UCLA, Dr. Cha received a three year research grant from the National Institutes of Health (Functional Neuroimaging and Transcranial Magnetic Stimulation in Mal de Debarquement; R03DC010451). Before and subsequent to NIH funding, Dr. Cha also received research grants from the MdDS Balance Disorder Foundation to extend her clinical studies of MdDS. These clinical research investigations have been productive and remain on-going.

Findings from Dr. Cha’s clinical investigations and scholarly activities to address MdDS have been published in the peer-reviewed literature as follows:

In 2012, clinical studies were conducted in the Human Balance Laboratory at the Icahn School of Medicine at Mount Sinai in New York City. Support for this clinical research was provided by the National Institutes of Health (Pilot Study on Mal de Debarquement; R21DC012162).

This study was completed and findings published in July 2014.

Emeritus Professor
Chronic Illness Research Team (CIRT)
School of Psychology
University of East London
London, UK

From 2010 through 2011, the Chronic Illness Research Team (CIRT) at the University of East London conducted studies to better understand the impact of MdDS on the lives of patients. Research updates provided by CIRT included:

  1. Factors contributing to memory problems in people with MdDS [December 2010; see update]
  2. Perceived stigma, illness intrusiveness, illness uncertainty and quality of life in people with MdDS [Summer 2011; see update]
  3. A qualitative investigation looking at the lived experience of individuals with MdDS – this involved being interviewed [Spring 2012; see update]

The CIRT studies were completed and findings published in October 2014.

Clinical studies designed to determine the efficacy of treatment of MdDS patients with repetitive transcranial magnetic stimulation (rTMS) were also conducted in Australia. The results of these investigations were published in the peer-reviewed literature in 2015.
