Clinical Trial Summary

The goal of this study is to determine whether external neuromodulation using transcranial electrical stimulation (TES) can reduce the perception of self-motion that is experienced by patients with 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. A similar form of rocking dizziness can be experienced without a motion trigger in individuals with certain risk factors. Treatment for MdDS is limited and morbidity is high.The goal of the study is to determine whether TES can suppress the rocking dizziness of MdDS either as a standalone therapy or as an adjunctive therapy to other forms of neuromodulation such as transcranial magnetic stimulation. The investigators will determine the optimal treatment duration and stimulation parameters.

Description:

Eligible participants who meet study criteria and pass the safety screen will be invited to participate in the study. If TES is used as add-on treatment to repetitive transcranial magnetic stimulation (rTMS), the training for TES application will be done on-site. However, in a portion of the study that does not involve rTMS, remote training will be performed via a webcam provided that a suitable "Study Buddy" is available to assist the participant. Participants will maintain web-based diaries of their symptoms for up to four weeks prior to treatment with TES. Before the actual treatment sessions are started, the subjects will complete baseline questionnaires online which will be repeated once a week for up to 12 weeks. Over the course of the study, the subjects will also keep a daily log of their sessions such as how many sessions they performed, for how long, and whether they had any side effects with each session. The studies will include a sham arm, allocated at a ratio of 1:1. On-site studies will involve the application of EEG, MRI, balance, cognitive, and visual/auditory stimulation tests.
