Discovery of the day
A prospective, multicentre single-arm trial demonstrated that unilateral MR-guided focused ultrasound (MRgFUS) pallidothalamic tractotomy is safe and effective for managing motor complications in Parkinson’s disease. However, the addition of a staged bilateral procedure provided only modest motor gains while significantly increasing the rate of persistent moderate-to-severe adverse events, particularly affecting speech, gait, and balance. For a PhD researcher developing preclinical pain models at the Brain and Mind Centre, this study underscores the critical importance of rigorous risk-benefit assessment when translating neurosurgical interventions from unilateral to bilateral applications, a consideration directly relevant to evaluating novel therapeutic strategies in chronic neurological conditions.
