Low-intensity focused ultrasound is described as being used for neuromodulation and for blood-brain barrier opening. In the abstract, these uses are linked to enabling therapeutic molecules to enter the central nervous system.

What the tool is doing
What problem it solves
It helps address central nervous system delivery barriers by allowing entry of therapeutic molecules. It is also positioned as a non-ablative focused-ultrasound modality relevant to disease modification.
It offers a possible non-open, non-radiation therapeutic option for epilepsy that may work through neuromodulation rather than only tissue ablation.
What it does not solve
Alternatives
The abstract contrasts this end of the spectrum with high-intensity focused ultrasound thermoablation and mentions deep brain stimulation as a related comparison context.
The abstract contrasts focused ultrasound broadly with open surgery and radiation exposure, but does not specify direct alternative neuromodulation platforms.
Evidence Snippets
This review examines the technical evolution of FUS and its expanded applications in GBM, including subtypes of low- and high-intensity FUS and their mechanistic contributions to therapeutic effect.
At the other end of the spectrum, low-intensity focused ultrasound has been demonstrated in both neuromodulation and blood-brain barrier opening to allow the entry of therapeutic molecules into the central nervous system.
Currently, FUS has been clinically applied for targeted brain ablation (high intensity [HIFU]) and neuromodulation (low intensity [LIFU])
Preliminary studies indicate ... potential neuromodulatory benefit and increased blood-brain barrier permeability of low-intensity focused ultrasound (LIFU).
