Device-based non-invasive brain stimulation (NIBS) techniques show promise for the treatment of neurological and psychiatric disorders, although inconsistencies in protocol designs and study findings can make the field difficult to navigate. In this Review, we discuss applications of NIBS for enhancing cognitive and motor function in people with various neurological diseases that are characterized by disruption of large-scale brain networks, including neurodegenerative diseases and brain lesion disorders such as stroke and traumatic brain injury. In particular, we focus on repetitive transcranial magnetic stimulation and transcranial electrical stimulation, as these techniques have been widely used in clinical settings and randomized controlled trials. We summarize and synthesize current knowledge, and highlight gaps and shortcomings in the existing research that make it difficult to draw firm conclusions, including small sample sizes, heterogeneous patient populations and variations in stimulation protocols. We believe that a rapid evolution of NIBS techniques from state-dependent, network-informed, multifocal and subcortical paradigms to individualized electric field modelling and accelerated NIBS protocols will improve the management of neurological disorders. However, realizing this potential will require us to address crucial challenges and acquire deeper mechanistic insights, with the aim of developing adaptive, biomarker-driven protocols to optimize target engagement, dosing and timing for each patient.

BACKGROUND: Temporal interference stimulation (TIS) is a novel noninvasive electrical stimulation technique to focally modulate deep brain regions; a minimum of two high-frequency signals (f1 and f2 > 1 kHz) interfere to create an envelope-modulated signal at a deep brain target with the frequency of modulation equal to the difference frequency: Δf = |f2 - f1|. OBJECTIVE: The goals of this study were to verify the capability of TIS to modulate the subthalamic nucleus (STN) with Δf and to compare the effect of TIS and conventional deep brain stimulation (DBS) on the STN beta oscillations in patients with Parkinson's disease (PD). METHODS: DBS leads remained externalized after implantation, allowing local field potentials (LFPs) recordings in eight patients with PD. TIS was performed initially by two pairs (f1 = 9.00 kHz; f2 = 9.13 kHz, 4 mA peak-peak per pair maximum) of scalp electrodes placed in temporoparietal regions to focus the envelope signal maximum (Δf = 130 Hz) at the motor part of the STN target. RESULTS: The comparison between the baseline LFPs and recordings after TIS and conventional DBS sessions showed substantial suppression of high beta power peak after both types of stimulation in all patients. CONCLUSIONS: TIS has the potential to effectively modulate the STN and reduce the beta oscillatory activity in a completely noninvasive manner, as is traditionally possible only with intracranial DBS. Future studies should confirm the clinical effectiveness of TIS and determine whether TIS could be used to identify optimal DBS candidates and individualize DBS targets. © 2025 The Author(s).
