Sample item

A man after a right middle cerebral artery stroke fails to shave the left side of his face and denies his left arm weakness. Which lesion best explains it?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

D. Right parietal lobe

The non-dominant (usually right) parietal lobe handles attention to both sides of space, so its damage causes hemispatial neglect of the left and anosognosia. The left parietal lobe seldom causes neglect.

Option by option

  • A. Left parietal lobe

    Left parietal lesions cause Gerstmann signs and aphasia.

  • B. Left frontal lobe

    Left frontal lesions cause expressive aphasia and right-sided weakness.

  • C. Right occipital lobe

    Occipital lesions cause visual field loss, not neglect of the body.

  • D. Right parietal lobe (correct)

    Correct. Right parietal damage causes left hemispatial neglect and anosognosia.
