Temporal lobe stroke commonly causes which deficit?

Temporal lobe stroke commonly causes which deficit?

• A. Impaired language comprehension
• B. Memory deficits
• C. Hearing loss
• D. Difficulty with color discrimination

Answer: (B)

Temporal lobes are central hubs for memory, especially the hippocampus and surrounding medial temporal structures that encode and retrieve new information. When a stroke damages this area, the brain’s ability to form new memories or recall recently learned details is impaired, leading to memory deficits. This is a classic and common outcome of temporal lobe injury, reflecting the role of these regions in memory circuits. If the stroke affects the dominant temporal lobe, language processing can also be affected, but memory problems remain the most characteristic feature overall. Hearing loss would require damage to the primary auditory cortex and is less routinely seen with temporal lobe strokes. Color discrimination involves other visual pathways and is not a typical hallmark of temporal lobe injury.
