My comments are in bold like this.
Some people are left with changes in emotional reaction or behaviour after a brain injury. These are more difficult to see than physical or cognitive changes. However, they can be the most difficult for the person and their family to deal with.
BB: I had no idea that a TBI would affect me emotionally, or change the way I acted. Like so many people, I figured that a bump on the head was just an external thing. I'd feel pain on my scalp, and maybe I'd feel a little woozy, but it would clear up in a few minutes... or hours. How wrong I was - so many times. Emotional and behavioral issues have been the bane of my existence (and my family's) for years and years, starting back in my childhood when my behavior was erratic, and my emotions were volatile.
Not everybody will experience these problems and their severity will also vary.
BB: The severity can vary from person to person, as well as from situation to situation. With me, I can be fine, one day... be not-so-great (but seem fine), the next... and then completely lose it a few days later. It's often cumulative, but nobody on the outside sees it building up. That happens inside. Where nobody can see. And when it erupts... hooo boy. The problem for me, is that when I blow up, it puts people off, and then they think that's how I always am... and then they walk on eggshells about it, all the time. And I sometimes never get a second chance, because they've made up their minds about me in a negative way.
This frequently occurs at a very early stage after the injury. It can be a coping mechanism for the person, who may be disorientated and very confused. It is most often a stage a person passes through, rather than a permanent change. Examples include: restlessness, pacing and pulling at intravenous tubes.
BB: I've been extremely fortunate to never having had intravenous tubes to pull at, but I know the feeling of not being able to sit still, being extremely agitated - especially after a TBI. A number of times, I can recollect getting hit in the head, and then being flooded with agitation and an overpowering need to MOVE! Like when I got hurt during an informal pick-up soccer game in high school, after the hit, when I was lying there, dazed and confused, I suddenly felt like I'd been given super-powers, and I leaped up and started playing like a crazy person. I don't think I played better than I had before I got hit, but I felt like I did. And I was ON FIRE - or so I thought. In another soccer game, when I got my bell rung, I knew I'd been hurt, but I felt this incredible urge to GET UP AND GO!!! And I started racing around the field -- in the wrong direction, no less. I nearly scored on my own team, which I think was a red flag for everybody on the sidelines. I did get taken out of that game, and I paced the sidelines in confusion and anger, because I NEEDED TO BE IN THERE! But it was wise to pull me from the game. I was not in good shape, at all. So, while agitation may be a coping mechanism for some, as they say above, I suspect it also has to do with the mechanism of the brain - the release of all those chemicals, and the general confusion that causes. The brain is trying to figure things out - plus, it's firing on ALL cylinders, like there's no tomorrow. In addition to being a behavioral coping mechanism, it's a result of the brain's basic function.
Explosive anger and irritability
If there has been damage to the part of the brain that controls emotional behaviour and the ability to tolerate frustration, emotions can swing to extremes. The stress of coping with even minor crises, such as misplaced shoes or a noisy vacuum cleaner, can be too much and trigger an angry outburst. If these stresses can be identified, it may be possible to reduce them.
BB: Amen to this. The part of the brain that controls emotions is particularly susceptible, as it's out in front and there are so many types of injury that can affect it. Car accidents, where your brain slams up against the inside of the skull... or tackles that snap your head back and forth... falls, etc. Minor events can turn into crises -- just being blindsided by a sudden change or something unexpected happening, can set me off. Little things can turn into huge things, in an instant. One minute, I'm fine, then all of a sudden, it's off to the races with emotional overload and over-reaction. Prolonged stress will also do a number on me, as will fatigue. The more tired I am, the more irritable I get - a tired brain is an agitated brain. And when I get too agitated, it's not cool. Sudden outbursts... extreme reactions... it's all part of a day in the life for me, sometimes. Unless I can get enough sleep and take good care of myself. If I can keep on my schedule and be smart about eating and drinking enough water, that helps. So does meditation and just taking time to chill out.
Lack of awareness and insight
The ability to recognize your own behaviours and change them when needed is a sophisticated skill that can be affected by brain injury. This can affect someone’s ability to: be self-aware; have insight into the effects of personal actions; show sensitivity; or feel empathy. It also means that a person may not fully appreciate or understand the effect that the accident is having on their life, health or family.
BB: I honestly had no idea how my TBI was affecting my household, back in 2005. I'd gotten injured at the end of 2004, and 2005 was the start of the downhill slide. I became incredibly self-centered and obsessed with myself. Small wonder - I had to recover and build myself back up, as my Sense-Of-Self had taken a huge hit. I didn't know who I was or what I was about, anymore, and it was devastating. I didn't recognize myself, and I was so caught up in figuring it out inside my head, that I never realized the extent of the changes on people closest to me (who were outside my head). It took talking with someone on a regular basis about what was going on with me, to help me see what an ass**** I was being, and to do something about it. Until I started talking to a neuropsych on a regular basis, I had no way to understand myself and objectively examine my behavior, because nobody I talked to actually understood how TBI affects the mind, body, and spirit... so they made all kinds of flawed assumptions about who I was and how I was. It was incredibly unhelpful for me, and it did more harm than good. I got lucky. A lot of others don't have that opportunity. And that's a damned shame. It's criminal, really.
