Compared to sham, tSMS significantly reduced the discomfort induced by high-intensity light stimuli.

Plain English Summary

Summary written for general audiences

In a sham-controlled double-blind crossover study, tSMS was applied for 10 minutes with a cylindrical magnet on the occiput of 20 healthy subjects. Researchers assessed subjective discomfort induced by low-intensity and high-intensity visual stimuli in a dark room before, during and after tSMS or sham. Compared to sham, tSMS significantly reduced the discomfort induced by high-intensity light stimuli.

Why This Matters

The study aimed to determine whether tSMS over the occipital cortex is effective in reducing experimental photophobia. The authors concluded that the visual cortex may contribute to visual discomfort in experimental photophobia, providing a rationale for investigating tSMS as a possible treatment for photophobia in migraine.
