Moderate to Severe Head Injury

Moderate to severe traumatic brain injury (TBI) involves a significant disruption in brain function caused by external force or rapid acceleration–deceleration, typically characterized by loss of consciousness lasting longer than 30 minutes, post-traumatic amnesia extending beyond 24 hours, or more pronounced abnormalities on neuroimaging. These injuries can often result in persistent impairments in cognition (e.g., attention, memory, executive functioning), emotional regulation, and behavior, with recovery trajectories that are more variable and frequently prolonged compared to mild TBI. Cognitive rehabilitation in moderate to severe traumatic brain injury involves structured, evidence-based interventions designed to improve or compensate for deficits in attention, memory, executive functioning, and other cognitive domains, with the goal of enhancing daily functioning and promoting greater independence.

Common Symptoms

• Memory difficulties
• Problems with attention or concentration
• Slowed thinking or processing speed
• Changes in mood, behavior, or personality
• Difficulty with planning or problem‑solving

How Neuropsychological Assessment Helps

Neuropsychological evaluation plays a central role in these cases by comprehensively assessing cognitive strengths and weaknesses, clarifying the functional impact of the injury, and informing cognitive rehabilitation planning. Results help guide decisions about return to work or independent living, identify needs for cognitive or behavioral interventions, and provide an objective framework for tracking recovery and long-term outcomes.

When to Seek Medical Advice

It is important to speak with a healthcare provider if you notice ongoing cognitive or behavioral changes following a head injury. A medical evaluation can help determine whether a referral for neuropsychological assessment is appropriate.
