Hello, Post concussion syndrome is a new term for me. I have never heard of it before coming here last week. I received a tbi when I was five about 42 years ago when I was hit by a car. Among other injuries, I had to relearn how to talk, and my personality was drastically changed. There has really been no therapy available for me when I was growing up. I just had to learn, relearn and adjust on my own. School was difficult for me, and I was always put in the slow classes. M y moods were always dark afterwards and as a result I have very volatile mood swings. I do talk with a therapist, and take a mood stabilizer which does seem to help. Other than that I just try to learn the best way I know how. I have developed skill as a medieval calligrapher over the past 5 years or so.
