This article isn't accessible so it's hard to see what you mean. Do you have a link to the full thing?

Found a similar previous one https://movementdisorders.onlinelibrary.wiley.com/doi/10.100... where out of 10 patients, 7 had issues:

> Tremor significantly improved in all patients. Seven experienced mild adverse effects, including 2 with transient gait impairment and a fall, 1 with dysarthria and dysphagia, and 1 with mild dysphagia persisting at 3 months.

Also can't access the full pdf either though.
