BL = baseline; K-WAIS = Wechsler Adult Intelligence Scale, Korean version; MRgFUS = magnetic resonance–guided focused ultrasound; pt. = patient; SD = standard deviation.
↵* Mean Memory Quotient scores increased significantly across the 24-month follow-up period (linear mixed model; F_3,6.5 = 236.3, p < 0.001).
↵† Mean values at 12 months were from 8 patients (data for patients 2, 4 and 5 were missing). Mean values at 24 months were from 10 patients (data for patient 11 were missing).
