Which of the following is a factor that drives recovery after neurological injury?

• A. Inactivity and lack of stimulation.
• B. Reversal of injury-related factors (like edema).
• C. Random chance alone.
• D. Excessive rest without therapy.

Answer: (B)

Recovery after neurological injury is driven by removing factors that worsen injury and create a better environment for healing. Reversing injury-related factors such as edema is central because edema raises pressure, reduces blood flow, and can expand secondary damage. When edema is controlled, perfusion improves and the tissue environment becomes more conducive to the surviving neurons’ recovery and to rehabilitation-driven reorganization of neural networks. This makes recovery more achievable as therapy helps harness that healthier environment to promote adaptive changes. Inactivity and lack of stimulation don’t promote recovery, random chance isn’t reliable, and excessive rest without therapy misses the opportunity to drive meaningful functional gains through guided rehabilitation.
