Zapping the brain to save speech: new hope for aphasia?

This study tested whether a gentle brain stimulation technique (tDCS) combined with language therapy can improve speaking ability in people with primary progressive aphasia, a condition that slowly destroys language skills. Twenty-three adults received either real or fake stimulation over 10 days. Researchers measured language changes right after treatment and up to 24 weeks later, and also used brain scans to understand who might benefit most.
