Description
Nilofar Sherzad and six co-authors published a stroke study in twenty twenty-five that asks where speech breaks when a stroke hits the brain's right side. Textbooks put speech on the left. Yet near half the right-side cases in this set of four hundred ten patients had speech trouble in the first two days.
The team mapped each patient's brain damage from scans and lined the maps up with a standard speech score. Harm in deep and side zones on both sides tracked with speech loss. The right-side speech zones mirror the left-side speech web, the maps suggest. The authors say acute speech loss is not a left-side tale alone. Their result may change how stroke teams read early scans and plan speech therapy.
