Had a traffic related head trauma. No obvious damage. How much chance i may develop memory loss or brain fog?

I would not spend time worrying about it. When i was a student i was honored to be able to study in the soviet union. I fondly remember the hospitality shown to us as a student group in the ukraine.Best wishes to you and your family in the upcoming holiday season. ...Read more
