Some time back, I compiled a list of possible issues TBI can introduce into your life. 
I combed through a bunch of sources and then put them all together, took out the duplicates, and came up with a list of common complaints related to traumatic brain injury. I’ve refined the list over the past couple of years, and I’m sure there are more issues I’ve missed, but this is what I’ve been working with, thus far. These apply to mild, moderate, and severe. And a lot of them are problems I have dealt with on a regular basis throughout the course of my life.
Here’s the list, broken down by category:

Now, some of them might look like they are duplicates — #3. Raging behavior should be grouped with #9. Angerrrrrr!!!, right? I’ve actually split them up because one is behavioral, and one is emotional/mood related. Just because you’re angry, doesn’t mean you’re going to have raging behavior, but anger can still be a significant problem.
One thing that struck me, as I was compiling this list over the past few years, is how many of the symptoms are physical. It almost doesn’t make sense. You injure your head, you hurt your brain, and your body starts acting up? Where’s the sense in that? Well, considering that the brain is like the command center of your body, I guess it does make sense.
The other thing that has jumped out at me, as I’ve considered this list over the years, is how the non-physical issues can often arise from the physical. Being dizzy all the time can really mess with your head, and it can make you cranky and mean and short-tempered. Likewise, having constant ringing in your ears can shorten your fuse and make you much more temperamental. And chronic pain has a way of depressing the heck out of you.
Now, not everyone with a TBI will have these issues, but lots of people will have one or more of these problems, and lots of them can come and go over time. It’s just one more handful of pieces to the puzzle that is TBI. A big handful, actually.
