Personality changes can stem from three sources. Perhaps the most common personality change after a head injury is increased aggressiveness. Studies have shown that around 30% of patients with traumatic brain injuries report having problems with anger and aggressive behavior.
Traumatic brain injury
(TBI) can significantly alter identity and personality. In one study, 75 percent of participants said they felt like a different person after brain injury.Traumatic brain injury can cause physiological changes in the brain that affect the way the brain processes and perceives information. Damage to the prefrontal cortex, responsible for managing behaviors and regulating emotions, has been linked to impulsive, inappropriate, and even criminal behavior. After a head injury, it's easy to react more drastically to a given situation than before of the injury. In “The Crash Reel”, one of Pearce's former snowboarding companions is also shown struggling with his own behavior after multiple brain injuries, demonstrating to viewers how people can be reshaped by physical trauma to their heads.
Brain injuries can damage connections that go from the cerebral cortex (the part of the brain that plays a role in memory, attention, perception, cognition, and awareness) to the limbic system (the part of the brain that supports functions such as emotions, behavior, and motivation). Finally, many patients with brain injuries appear to develop a more egocentric personality after the head injury. Next, you'll discover different types of emotional and behavioral changes that can affect personality after a head injury. As a result, personality changes after brain injury can change the way patients relate to the people they love the most.
While many people know that brain injuries can cause physical problems, such as headaches, dizziness, memory problems, and problems with maintaining balance and gait, what often goes unnoticed (except for family members, friends, and even some of the survivors themselves) are the personality changes that occur when the brain suffers brain injury. This overstimulation is the cause of much of the irritation, angry outbursts, aggressive behavior, and mood changes you may experience after a head injury. After a concussion or any blow to the head, you go to the doctor and he says that you could have a concussion, but that's no big deal because you. He states that 90 percent of patients at his clinic who have suffered a head injury in the past experience psychological or personality changes, adding that what's even more surprising is that many of them had a brain injury as children that went unchecked.
Finally, people who have suffered multiple brain injuries are at greater risk of developing symptoms of depression and committing suicide. Personality changes after a head injury are some of the most difficult symptoms of traumatic brain injury to treat, both for the patient and for their loved ones. When a head injury or concussion causes changes in a person's emotions and behavior, it can, therefore, cause an apparent change in their personality. However, it's important to remember that your loved one's personality is still intact, only hidden under these effects due to direct brain injury.
