Select the behavioral effect that may occur due to a traumatic brain injury.

Traumatic brain injuries (TBIs) can lead to a variety of behavioral changes, and one common effect is an increase in frustration tolerance. Individuals with TBIs may experience difficulty managing their emotions and coping with stress, which can make them more prone to feelings of frustration and irritability. This is often due to the impact of the injury on the brain's emotional regulation centers and overall cognitive function.

While headaches, difficulty concentrating, and blurry eyesight are also common symptoms following a TBI—often related to the physical and cognitive impairments that result from the injury—they do not directly pertain to behavior in the same way that easily getting frustrated does. Emotional changes can significantly affect a person's social interactions and daily activities, making the increased likelihood of frustration a key behavioral concern following a TBI. Understanding this allows trainers and caregivers to better support individuals recovering from such injuries by addressing not only physical rehabilitation but also emotional and behavioral coping strategies.
