Course: Tic Status in Tourette Syndrome Due to Depletion of the Deep Brain Stimulation Battery

CME Credits: 1.00

Released: 2023-01-03

A 29-year-old, right-handed, otherwise healthy man developed severe lifelong Tourette syndrome (TS) beginning at the age of 6 years. Due to its refractory pattern, he underwent deep brain stimulation (DBS) implantation at the centromedian-parafascicular complex thalamic () when he was 23 years old. His symptoms significantly improved with a Yale Global Tic Severity Scale score reduction from 95 to 28 (). Improvement was clinically sustained over time using high stimulation parameters (ventral contacts bilaterally with 3 mA, 90??s, and 160?Hz). However, after a while, he stopped attending proper follow-up appointments until his condition markedly worsened, which led him to return to our hospital.
