Which symptom is most characteristic of a left-hemisphere stroke?

Language processing is typically localized in the left hemisphere for most people, so a stroke here often disrupts language. Impaired comprehension signals receptive aphasia, usually from damage to Wernicke’s area in the left temporal-parietal region, where speech remains fluent but understanding is affected. This makes comprehension trouble the most characteristic sign of a left-hemisphere stroke. While left-sided strokes can cause right-sided weakness if motor areas are involved, that isn’t as specific to the left side as language problems. Spatial-perceptual deficits tend to arise from right-hemisphere strokes, and impulsivity/disinhibition is more linked to frontal-right hemisphere damage.
