By Matthew Stock A new treatment being developed by scientists from Imperial College London could end the misery of motion sickness. By suppressing certain brain signals they found they could speed up a person’s ability to adapt to motions that had previously caused symptoms such as dizziness, nausea and vomiting. Research from Imperial College London, recently published in the scientific journal Neurology, explained how motion sickness occurs when what the eyes see and what the inner ear senses are confused.
We know that people without a functioning balance system are almost immune or highly resistant to developing the cardinal symptoms of motion sickness, which are nausea and vomiting.
Dr Qadeer Arshad
So we initially go people on the chair and found out how susceptible they were, so we measured how long it took them to develop motion sickness. We then applied a stimulation; either the test or the control, i.e. the placebo.
The reason that we can’t understand these motions; the brain if you like can’t understand these motions, is that there’s continual conflict between what is upright and whether you should lean to balance yourself in the environment or whether you’re actually experiencing a sideways acceleration force.
