Behaviors to Expect from Different Types of Brain Injuries

The adult child of a senior discusses the common behavioral changes that come from different types of brain injuries.

Learn what behavioral changes to expect from different types of brain injuries.

While there are different types of brain injuries, there are behavioral changes that are to be expected no matter what type of injury occurred. Some problematic behaviors might be more or less likely depending on the area and extent of the trauma, but your loved one might demonstrate one or more of these behaviors during TBI recovery, regardless of the specifics of the injury.

The first step in handling inappropriate behavior in a loved one with a brain injury is to understand what those behaviors are so that you can identify them – not taking them personally, helping when possible, and intervening when required. Familiarizing yourself with the behaviors that follow different types of brain injuries can ensure that you respond in the most effective way for yourself and your loved ones.

Emotional Volatility – Emotional volatility, also known as emotional lability, is a sudden, frequently exaggerated mood swing that is often extreme and may come across as an overreaction.

Sexual Inappropriateness – People who have experienced a TBI may see an increased interest in sex, a reduced interest in sex, or a lack of understanding about the contextual appropriateness of a sexual expression or behavior.

Personality Changes – Personality changes are natural in life, but people with a TBI can experience extreme, abrupt personality changes that can be disorienting to the people who know and love them.

Poor Concentration – It’s common for people to be easily distracted, have difficulty with multitasking, or lose track in a discussion or experience information overload after a brain injury.

Empathy Issues – A loved one may come off as self-centered after a brain injury. For example, they might demand rather than ask politely, or say things that hurt your feelings or are unrealistic without seeming to care. The lack of empathy is not a lack of love. It is an injury-related problem caused by issues with abstract thinking skills.

Denial – It is normal for people with traumatic brain injuries to adamantly insist that they are not having any problems. At times, this is due to the actual brain injury, but it also can be basic denial unconsciously executed as a coping mechanism to postpone the confrontation of fear and/or uncertainty about how to navigate the realities of life after trauma.

Inappropriate Emotional Responses – Your loved one may not demonstrate emotional responses to stimuli that triggered those very responses before the brain injury. They may not laugh when something is amusing, smile when seeing something pleasant, or cry when something is sad. The response might also be contextually unsuitable, not matching the current state. For example, they may laugh when sad or cry for no particular reason.

Memory Problems – No matter what type of brain injury occurs, most people expect memory loss problems. Short-term memory problems or amnesia can occur, but, surprisingly, the retention of new information is the most typical memory-related issue people will likely experience from brain trauma.

Aggression – Aggressive behavior after a brain injury is quite common. Knowing what triggers an aggressive response for your loved one can help in avoiding the behavior.

If you understand what behaviors are prevalent in different types of brain injuries, you can be ready for them as they surface and see them for what they are – a symptom of the injury. They are not a reflection of the person’s opinion or emotional investment in you.

Understanding Behaviors Caused by a Traumatic Brain Injury

Do you know the possible behaviors caused by a traumatic brain injury?

There’s no organ more essential or complex than the brain. It dictates any and everything that goes on with the body. It operates in the background, keeping us alive, and, in the foreground as the home of our cognizance. That is why, naturally, when someone suffers from a traumatic brain injury, there is so much concern.

At San Diego Home Caregivers, we believe that learning about the possible behaviors caused by a traumatic brain injury in relation to the location in the brain where the damage occurred can help families better understand and make more informed decisions about their loved one’s care.

  • Occipital Lobe: The occipital lobe controls our sense of sight. The effects of an occipital lobe injury might include vision problems, such as blurred vision or blind spots, hallucinations, visual illusions, the inability to recognize the movement of an object, or problems with reading and writing.
  • Cerebellum: Our coordination, movement, and balance are controlled by the cerebellum. A cerebellum injury may cause an individual to lose the ability to do things that require coordination, such as walking, talking, or reaching out to grab something. It can also cause tremors, dizziness, and/or slurred speech.
  • Temporal Lobe: Our language comprehension, memory, hearing, learning, and sequencing are all controlled by the temporal lobe. It lets us recognize faces and generates feelings. The effects of a temporal lobe injury can include problems with key functions as well as changes in sexual behavior, persistent talking (specifically with right lobe damage) and increased aggression.
  • Parietal Lobe: We can thank our parietal lobe for our comprehension of language, sense of touch, spatial awareness, visual perceptions, and sense of time. When this area of the brain is injured, people may encounter difficulty reading, the inability to draw or name items, challenges with distinguishing right from left, difficulty with math, and an unawareness of or neglect of certain body parts. They will also commonly have problems with hand-eye coordination.
  • Brain Stem: The brain stem controls the basic mechanisms of life, including heart rate, respiration, digestion, and blood pressure. It is the home of the startle response and reflex emotions, wake and sleep cycles, and our ability to sneeze, cough, vomit, and swallow. Brain stem damage can lead to problems with all of these basic mechanisms, including impacting speech, due to a diminished capacity for breathing.
  • Frontal Lobe: The frontal lobe is home to a person’s personality, intelligence, and emotions. It is the region of the brain that controls concentration, makes judgments, and solves problems. It also controls body movement, including writing and speech. The effects of a frontal lobe injury can include changes and/or problems with the core functions controlled by the frontal lobe in addition to more subtle manifestations of the core functionality, such as a lack of inhibition, an impaired sense of smell, vision loss, persistence of a single thought, and mood swings.

Despite how many intricate parts make up the brain, it functions as a whole. Challenges with behaviors or functions can cascade, as can accomplishments gained through rehabilitation. If you have a loved one with a traumatic brain injury and could use help with caregiving due to the behavioral or physiological effects of the person’s trauma, San Diego Home Caregivers can help.
