Hi Mrs. Ortega, the first week I was in college, in a game I was knocked down by a strong guy when he was running fast, I still can recall the feeling as if the brain was pushed roughly and quickly to the other side and pulled back hard right away. For 10-15 seconds I was barely conscious. After that I was a bit dizzy but I then was okay. Didn't see a Dr. I was so young. You know what? I had 7 years depression after that, without any reason. It was so hard for me to regain myself in 7 years' time. Now 10 years have passed, one day, when I talked to my friend who went to medical school, he said, you probably had a concussion at that moment, and the depression is a post-concussion problem. I'm trying to say that please take her to see a Dr. and get medical support as much as possible. Don't let what happened to me happen to your daughter.
