Lesions in visual processing areas may lead to which functional deficit?

• A. Affect balance and increase risk of trips
• B. Improve balance
• C. Improve gait
• D. Enhance depth perception

Answer: (A)

Visual processing areas help the brain interpret what we see and use that information to stay upright and navigate our environment. When these areas are damaged, the brain’s interpretation of visual cues becomes unreliable, which can throw off balance and the ability to judge steps, obstacles, and surface changes. That disruption often leads to instability and a higher risk of tripping. Depth perception and precise gait typically depend on intact visual processing; lesions usually impair these functions rather than improve them. So, the most consistent deficit is balance problems with an increased risk of trips, not improvements in balance or gait, and not enhanced depth perception.
