Mal de Debarquement Syndrome (MdDS) Treatment at Mount Sinai

Since 2014, we provide the first experimental treatment of MdDS, which is successful in approximately 75% of cases who contracted MdDS by motion events, and about 50% of cases who acquired MdDS spontaneously (no apparent motion involved).

Mal de Debarquement Syndrome (MdDS) commonly occurs after sea voyages and is primarily characterized by a sense of rocking, swaying, and bobbing (“sea legs”). Generally, these sensations may only last for a short period of time from minutes to days. However, for some travelers these sensations last a much longer time, from months to years. This is so-called persistent MdDS. If this occurs, the primary symptoms of rocking are usually accompanied by a number of equilibrium, cognitive and psychological dysfunctions, which may severely reduce the quality of life and ability to work.

To make an appointment, please contact our patient’s coordinator bty email at

Furthermore, you do not need to have official MdDS diagnoses before coming to our treatment, but you need to complete patient’s Intake Form which we e-mail to you on your request.


Recently, our research has focused on motion sickness in MdDS. We are working to raise $10,000 for a small pilot study to determine whether the motion sickness protocol for MdDS patients can improve the motion sensitivity commonly seen in concussion patients. To make your donation, please, contact Mr. Thom Harmon at and specify that the donation is for Dr. Yakushin’s concussion research.

It is with deep sadness that we announce the passing of our friend and colleague Dr. Mingjia Dai, who lost his battle with cancer and passed away peacefully on February 7, 2019. Our thoughts and prayers are with his family and friends.
