Source published October 20, 2026: peer-reviewed clinical and multimodal-neuroimaging study in Neural Regeneration Research.
A direct protocol comparison Researchers analyzed 101 people with mild cognitive impairment who completed 10 days of repetitive transcranial magnetic stimulation. Fifty received stimulation over the left dorsolateral prefrontal cortex, while 51 received sequential stimulation over that target and the precuneus.
What changed The multisite group had larger gains on global cognition, immediate verbal recall and animal fluency than the single-site group. MRI analyses also found broader structural and functional changes, and some imaging changes correlated with cognitive change. Those correlations do not show that the imaging findings caused improvement or establish neural repair.
The important boundary Both groups received active rTMS. The accessible abstract does not describe random allocation, masking, a sham group, durability after treatment or adverse events. The study therefore supports a promising relative protocol signal, not proof that rTMS outperformed no stimulation. Funding and conflict details were not available in the checked abstract.
Why it matters The study tests whether pairing targets from a cognitive network may be more useful than stimulating one site alone. Randomized, masked, sham-controlled trials with longer follow-up, daily-function outcomes and complete safety reporting are needed before the approach can guide care.
