Which cognitive domains are commonly targeted in rehabilitation after traumatic brain injury?

• A. Hearing, smell, taste, proprioception
• B. Mood only
• C. Attention, memory, executive function, processing speed, language, visuospatial skills
• D. Motor strength, reflexes, balance

Answer: (C)

Cognitive rehabilitation after traumatic brain injury is built around improving thinking skills that organize and guide everyday tasks. The most impactful domains to work on are attention (staying focused on a task), memory (encoding, storing, and retrieving information), and executive functions (planning, problem-solving, flexibility, and self-monitoring). Processing speed matters because how quickly someone can take in information and respond affects almost every activity. Language skills—such as naming, understanding, and expressing ideas—and visuospatial abilities—like judging spatial relationships and navigating environments—are also commonly targeted because they underlie communication, learning, and safe independence in daily life.

Other areas like sensory functions (hearing, smell, taste, proprioception) and motor skills (strength, balance) are important components of rehab, but they fall into different rehabilitation domains. Mood can be addressed as part of comprehensive care, but the commonly targeted cognitive rehabilitation focuses on these six cognitive domains that most directly influence thinking, learning, and everyday function after brain injury.
