What is MdDS (mal de débarquement syndrome)?

MdDS stands for mal de débarquement syndrome, French for "illness of disembarkation". It is a rocking, swaying or bobbing feeling that carries on after you have stopped moving.

Most people have felt a short version of this after a boat trip. In MdDS the feeling does not fade after a few hours or a day. It can last weeks, months or longer.

What it feels like

How it often starts

It usually begins after travel: a cruise, a ferry, a long flight or a long train ride. Sometimes it starts without any travel.

How it is diagnosed

There is no single test. A doctor, often an ENT specialist or neurologist, makes the diagnosis from your history and checks for other causes.

How it is managed

Options are discussed with your clinician. They may include specific rehabilitation approaches, medicines in some cases, and looking after sleep and stress, which can make symptoms worse. Some people improve over time without treatment.
