Which term describes a broadly distributed brain injury that affects cognition?

• A. Dysarthria
• B. Amnesia
• C. Global Damage
• D. Cognitive Distortion

Answer: (D)

When brain injury affects many parts of the brain, it tends to produce a broad, overall decline in thinking skills. This is described as global damage, because the injury isn’t confined to a single area but spans multiple networks that support memory, attention, language, problem solving, and processing speed. That widespread disruption explains why cognition is broadly impaired. Dysarthria, by contrast, is a motor-speech disorder rooted in muscles and control of speech, not a global cognitive decline. Amnesia refers to memory loss, which is a specific cognitive domain rather than a widespread cognitive profile. Cognitive distortion describes biased or faulty thinking patterns, typically discussed in psychological therapy, not a physical brain injury. Therefore, global damage best fits the idea of a broadly distributed brain injury affecting cognition.
