Arif Dalvi and colleagues report important prospective evidence on the use of MRI-guided focused ultrasound pallidothalamic tractotomy in Parkinson's disease.1 Their findings on second-side treatment raise the question of how adverse events should be interpreted in the context of bilateral homologous lesioning (ie, repeating the same target in both hemispheres) and whether the same irreversible target should be repeated contralaterally.
