Brief Summary:
The goal of this study is to determine whether external neuromodulation using repetitive transcranial magnetic stimulation (rTMS) can reduce the perception of self-motion that is experienced by individuals with mal de debarquement syndrome (MdDS). Mal de debarquement is translated as the "sickness of disembarkment," and refers to the chronic feeling of rocking dizziness that occurs after exposure to passive motion. Treatment for MdDS is limited and morbidity is high. The goal of the study is to determine whether rTMS can suppress the rocking dizziness of MdDS and to determine whether imaging and electrical biomarkers can aide in more effective targeting. The investigators will make correlations between functional magnetic resonance imaging (fMRI), electroencephalography (EEG), and specific clinical features to determine whether functional connectivity between particular hubs in the brain correlate with clinical improvement.

Condition or disease Intervention/treatment Phase
Mal de Debarquement Syndrome Device: Transcranial Magnetic Stimulation Not Applicable

Detailed Description:
Participants will maintain web-based diaries of their symptoms for two weeks prior to treatment with rTMS. Up to 20 treatments with rTMS with either anatomically or functionally determined targets will be administered. Treatments will be preceded by an fMRI scan and EEG recording prior to the first rTMS treatment and will be followed by an fMRI and EEG after the last treatment. Post treatment diaries will continue for up to 12 weeks after rTMS administration.

Arm Intervention/treatment
Experimental: Transcranial Magnetic Stimulation
After determination of the motor threshold, the TMS coil will be positioned at predetermined locations over the brain using MRI guidance and a frameless stereotaxy system. A train of stimulation pulses (repetitive TMS) at 1Hz up to 10Hz or in theta burst mode will be delivered at one or more locations over the head, depending on the brain location under study (brain locations determined by MRI data). Real or active sham conditions will be used in the study but all participants will receive real treatment at some point during their enrollment. Real rTMS over one area may also be compared to real rTMS over another area.
Device: Transcranial Magnetic Stimulation
A form of external neuromodulation using pulsatile magnetic fields on the surface of the head.

Primary Outcome Measures :
  1. Dizziness Handicap Inventory [ Time Frame: 10 years ]
