Good, Evil and a Bump On The Head

Post by Lowen Quicksilver on Thu Mar 03, 2016 12:24 pm



In the brain injury (link is external) world, there are taboo subjects that family caregivers can't wait to talk about among ourselves. The dark side of personality (link is external) change is at the top of the list. In my recent post, After Brain Injury: Learning to Love a Stranger, I shared my experience of building a new relationship and marriage with my husband Alan. Alan suffered a severe anoxic brain injury (link is external) following a massive heart attack and cardiac arrest.

In this post, I'll tell you more about the impact of personality change after brain injury. On Sunday, in Part II, I'll describe some of the strategies we used to help Alan manage anxiety (link is external) and anger (link is external).

Most of the time, Alan displayed his engaging pre-injury personality marked by kindness, love, curiosity, and humor. However, post-injury personality changes also meant that we dealt with bouts of intense anger, confusion, and unpredictable behavior. Sometimes his moods shifted so suddenly that I called it "Jekyll and Hyde (link is external)syndrome." It was as if two versions of Alan resided within him. One was rational and easy-going, but the other was frightening and even dangerous at times.
Why brain injury affects emotions

First, some background. Brain injury sometimes causes subtle or pronounced changes in personality. Damage to specific areas of the brain, including the frontal and temporal lobes, amygdala, and hippocampus (link is external) might leave the survivor vulnerable to agitation, volatile emotions, memory impairment, verbal attacks, physical aggression, and impaired impulse control.

Physical vulnerability combines with emotional responses to life changes to cause problems. These problems might occur only occasionally, or be a repeated challenge to daily functioning and relationships.

Alan had damage to the areas above, and that meant his executive functions (link is external) were impaired. Executive functions refer to the complex group of skills we use to plan, make decisions, problem solve, self-monitor, make sound judgments, and get along with others. He also had both short and long term memory impairmen (link is external)t. The combination, not uncommon in severe brain injury, was the "perfect storm" for behavioral outbursts. (link is external)The angry outbursts could be triggered by his awareness of losses, wanting more control over his life, or not understanding the reasons behind safety measures such as no longer being able to drive his car. I understood that they were an attempt to communicate distress and handle the situation as he saw it.

We worked hard to prevent and minimize the outbursts, and to use strategies to improve communication and self-control. However, there were plenty of times when Alan's darker side emerged.
Psychiatric issues after brain injury

Brain injury can also contribute to psychiatric issues including depression (link is external), severe anxiety, substance abuse, (link is external) or obsessive compulsive disorder (link is external). Some survivors experience post-traumatic stress disorde (link is external)r (PTSD) as a consequence of the circumstances and medical events that caused the brain injury. In addition to damage to specific areas of the brain, Alan's brain injury disrupted the production and function of neurotransmitters (link is external)thatinfluence mood and thought regulation.

We quickly learned that anxiety or depression made Alan more susceptible to angry outbursts or threatening behavior. He often responded well to the judicious use of medications to modulate depression, anxiety, and agitation for years after the injury. We never used medications in place of attention, communication, behavioral strategies and keeping environmental stimulation within his comfort zone. However, I came to appreciate their value.
So, how did personality change impact us?

1. Disrupted trust—When we were getting to know each other all over again, the unpredictability of Alan's angry eruptions or accusations made it harder to rebuild the trust so essential for any relationship.
2. Personal integrity—When Alan remembered what he had said or done, he often felt ashamed, guilty, and "Like some other guy is living inside me, not myself."
3. Emotional pain—On many occasions, Alan yelled at me, and then took a nap to calm down. When he awoke, he couldn't recall what he had done and didn't believe my explanation. He would justify his response by saying, "Well, I yell at you because you deserve it; you control my life and won't let me drive." I'd be left feeling angry and hurt. Caregivers are human too, and even understanding doesn't cushion the sting sometimes.
4. Unresolved conflicts—I learned early on that you can't have a constructive argument with a person who has a brain injury or memory loss. Biting my tongue and suggesting a proven technique to calm down was more fruitful. And yet, I yearned to have the kind of argument couples have to clear the air and resolve a problem.
5. Decreased intimacy—There were several times when Alan said hurtful things and threw his clothes around in an agitated outburst. He quickly forgot the incident and suggested that we make love. I withdrew, since it took me days to guardedly trust in his predictability again.
6. Risk of injury—Alan never struck me, but he did hit his home health aide and threaten to hit others. When angry, he rallied his limited strength and could be dangerous. Families need training in how to prevent or deal with such incidents. Even health care professionals are unaware of how common verbal and physical aggression are at home.

With the findings of personality changes from head injuries, lobotomies, and drugs like LSD and PCP could be an indication that good and evil are in the mind and not the soul. Not ruling out the existence of a soul, just pointing out the possibility of the soul taking a more passive role and is merely "experiencing" life.
