Study links gum disease to greater white matter changes in the brain

Research published October 22, 2025, in Neurology® Open Access reports that older adults with gum disease had more white matter hyperintensities—a marker of tissue damage—than peers without gum disease, even after accounting for other risks.
Epia Neuro, a newly launched startup in San Francisco, is developing a brain-computer interface to help stroke patients regain hand movement. The system combines a brain implant with a motorized glove. Stroke remains a leading cause of long-term disability, affecting hand and arm function in about two-thirds of survivors.

A new study reveals that after a stroke, the undamaged side of the brain can appear biologically younger as it compensates for lost function. Researchers analyzed MRI scans from over 500 stroke survivors worldwide using AI models. The findings suggest neuroplasticity helps explain persistent motor impairments.
