Which factor would likely enhance the recovery of brain function after injury?

Engagement in rehabilitation is crucial for enhancing recovery of brain function after an injury. Rehabilitation often includes various therapies aimed at helping individuals regain lost skills and adapt to changes in their cognitive and motor functions. Programs may involve physical therapy, occupational therapy, and cognitive exercises, all designed to encourage neuroplasticity—the brain's ability to reorganize itself by forming new neural connections. This process is often vital for recovery, as it allows the brain to compensate for lost functions and improve overall performance over time. Engaging actively in rehabilitation can provide structured support and motivation, ultimately leading to more significant functional improvements compared to a lack of such intervention.

In contrast, factors such as advanced age, high levels of stress, and alcohol consumption generally have a negative impact on recovery. Advanced age can be associated with slower healing processes and reduced neuroplasticity. High levels of stress can hinder cognitive function and inhibit the brain's ability to recover effectively. Alcohol consumption is also detrimental, as it can lead to further cognitive impairment and hinder the body's natural recovery processes.
