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.

Outcome Measures
Primary Outcomes (1)
Dizziness Handicap Inventory
The Dizziness Handicap Inventory is a widely used measure of subjective dizziness in which 25 questions of dizziness inducing events are rated on a scale of 0-2-4. The maximum number of points is 100 points which are divided into the following levels: 16-34 Points (mild handicap), 36-52 Points (moderate handicap), 54+ Points (severe handicap).
10 weeks (4 pre stimulation + 6 post stimulation)
Secondary Outcomes (2)
Mal de Debarquement Balance Rating Scale
10 weeks (4 pre stimulation + 6 post stimulation)
Hospital Anxiety and Depression Scale
10 weeks (4 pre stimulation + 6 post stimulation)
Study Arms (3)
Target 1: Occipital Cortex
EXPERIMENTALAfter determination of the motor threshold, the TMS coil will be positioned over the midline occipital cortex using MRI guidance and a frameless stereotaxy system. A train of stimulation pulses in continuous theta burst mode will be delivered.
Target 2: Cerebellar Vermis
EXPERIMENTALAfter determination of the motor threshold, the TMS coil will be positioned over the midline cerebellar vermis using MRI guidance and a frameless stereotaxy system. A train of stimulation pulses in continuous theta burst mode will be delivered.
Target 3: Cerebellar Hemisphere
ACTIVE COMPARATORAfter determination of the motor threshold, the TMS coil will be positioned over the lateral cerebellar hemisphere using MRI guidance and a frameless stereotaxy system. A train of stimulation pulses in continuous theta burst mode will be delivered.
Interventions
A form of external neuromodulation using pulsatile magnetic fields on the surface of the head.
Eligibility Criteria
You may qualify if:
- Age ≥18 years old
- Willing and capable of interacting with the informed consent process
- Primary disorder being a persistent rocking dizziness triggered by passive motion such as from water, land, or air travel and with no other central nervous system or peripheral vestibular disorder determined after appropriate evaluation.
You may not qualify if:
- Subjects who cannot comply with study conditions.
- Active psychiatric condition such as mania or psychosis
- Unstable medical condition
- Implanted metal anywhere in the body (infusion pumps, pacemakers, metal or shrapnel in the body, deep brain stimulators, aneurysm clips, metal prostheses, joints, rods or plates). Dental fillings are acceptable.
- Personal history of seizures or a first-degree relative with epilepsy
- Medications known to lower seizure threshold such as: typical (high-potency) neuroleptics and tricyclic antidepressants: Subjects who take one or a combination of the following drugs will be excluded: imipramine, amitriptyline, doxepin, nortriptyline, maprotiline, chlorpromazine. clozapine, foscarnet, ganciclovir, ritonavir, amphetamines, cocaine (including MDMA, ecstasy), phencyclidine (PCP, angel's dust), ketamine, gamma-hydroxybutyrate (GHB), theophylline, haloperidol, fluphenazine, bupropion.
- Pregnancy or planning to become pregnant during study enrollment.
