ESSENTIAL TREMOR

This study tested a two-step ultrasound treatment for people with severe hand tremors that don't respond to medication. Seven participants received focused ultrasound on one side of the brain first, then the other side at least 9 months later. The goal was to see if the staged ap…

This study tested whether a new type of PET scan can tell the difference between Parkinson's disease and essential tremor as well as the current standard SPECT scan. 152 adults with either condition received both scans. The goal was to see if the newer method is at least as accur…

This study tested a wearable device designed to reduce upper limb tremors in people with essential tremor. 71 participants used the device to see if it was safe, comfortable, and helpful for daily tasks like using a spoon or pouring milk. The goal was to ease symptoms and improve…

This study tested a non-invasive technique called transcranial direct current stimulation (tDCS) to see if it could reduce tremors in people with essential tremor. 16 adults with moderate to severe tremor that didn't respond well to standard treatments received mild electrical st…

This study tested whether ultrasound imaging can detect and model hand tremors in people with Parkinson's disease or essential tremor. Researchers used the ultrasound data to design electrical stimulation that might suppress tremors during grasping. The study involved 12 adults a…

This study aimed to learn more about why people have tremors by observing brain activity and movement in 85 adults with conditions like Parkinson's disease, essential tremor, or dystonia, as well as healthy volunteers. Participants completed tasks while researchers used tools lik…

This study measured brain signals in 21 people with essential tremor or Parkinson's disease during deep brain stimulation (DBS) surgery. The goal was to understand how the brain's motor network produces tremor. The findings may help improve future treatments, but this study did n…
