How can a traumatic brain injury change someone’s personality?

On Behalf of | Sep 11, 2023 | Personal Injury

A traumatic brain injury is a life-altering event that can profoundly affect an individual’s personality. Learning about how a TBI can reshape a person’s character and behaviors is important.

Part of this includes shedding more light on the less obvious emotional and cognitive changes that often accompany this condition.

Quick emotional shifts

A TBI can lead to erratic emotional responses. A person who was once calm and composed may become irritable or quick-tempered. This emotional volatility stems from the brain’s altered ability to regulate emotions effectively.


TBIs can diminish an individual’s ability to think before acting. This may result in impulsivity, causing them to make hasty decisions without considering the consequences.

Social withdrawal

Previously outgoing individuals may withdraw from social interactions after a TBI. They may struggle with communication and find it hard to engage in meaningful relationships due to cognitive and emotional impairments.

Memory issues

One of the most common cognitive changes following a TBI is memory impairment. Individuals may have difficulty recalling recent events or forming new memories.

This can lead to frustration and a sense of isolation. Since Americans faced 69,473 deaths in 2021 due to traumatic brain injuries, checking in on people with a possible TBI is important.

Reduced cognitive flexibility

A TBI often impairs cognitive flexibility, making it difficult for individuals to adapt to new situations or ideas. This can result in rigid thinking patterns, limiting their ability to problem-solve effectively.

Lack of empathy

Some TBIs can diminish an individual’s capacity for empathy. They may struggle to understand or connect with others’ emotions and experiences, which can strain relationships with family and friends.

Support and therapy can play an important role in helping those with TBIs adapt to their new reality and work toward rehabilitation and recovery. Spending time recognizing these symptoms is key when first dealing with this injury.
