Hemi neglect is typically due to a lesion in which area of the brain?

• A. Left frontal lobe
• B. Right parietal lobe
• C. Right occipital lobe
• D. Left temporal lobe

Answer: (B)

Hemi neglect, or spatial neglect, is often associated with lesions in the right parietal lobe. This condition occurs primarily after right hemispheric damage, leading to an individual being unaware of or ignoring stimuli on the left side of their body and environment. The right parietal lobe plays a critical role in attention and spatial awareness, especially regarding the left visual field. Consequently, when there is damage in this region, it disrupts the brain's ability to process information from the left side, resulting in reduced awareness of that side, which is characteristic of hemi neglect. Understanding this association is vital for diagnosing and planning rehabilitation for patients exhibiting symptoms of hemi neglect. The other areas mentioned, while involved in various cognitive and perceptual functions, do not directly correlate with the condition of hemi neglect in the same manner as the right parietal lobe does.
