What behavioral changes can result from a traumatic brain injury (TBI)?

One significant consequence of TBI is impulsivity and aggression. This occurs because the areas of the brain that govern judgment, self-control, and emotional responses can become compromised. As a result, individuals may find it difficult to resist immediate urges or control their anger, leading to increased impulsivity and aggressive outbursts.

Impulsivity can manifest as making hasty decisions without considering the consequences, while aggression might be expressed through verbal outbursts or physical altercations. Research has shown that these behaviors are more common after TBIs, particularly when the injury affects the frontal lobes, which are integral for managing complex social behaviors and impulses.

The other options reflect behaviors typically not associated with TBI outcomes. For instance, while some individuals may strive to enhance their focus and attention, TBI often results in decreased cognitive functions, rather than improvements. Enhanced social interactions may also decline due to difficulties in processing social cues and understanding others’ emotions following a TBI. Lastly, emotional responses are often heightened rather than reduced; individuals may exhibit more extreme emotional reactions, reflecting instability in emotional
