U.S., March 28 -- ClinicalTrials.gov registry received information related to the study (NCT06899022) titled 'Attention and Eye Movement in Parkinson's Disease' on March 14.

* Does therapeutic DBS improve or worsen attentional and perceptual deficits for social cues in PD and ET?
* Can DBS be optimized to restore normal attentional control...
