Lee and colleagues published a new study involving 20 patients who underwent DBS of the amGPi \citep{Lee2023}. Interestingly, they employed quite unusual stiumulation parameters with lower frequency (around 80 Hz), and higher pulse width (around 120 µs) than commonly used.  At 1 year, 60% of patients had a >35% reduction on the on the YGTSS. Initial response appeared to predict improvement on the YGTSS at one year, and the effect at 12 months was more pronounced than at 3 months.
