Would really value views on this. My son is 7 and during the course of his 7 years he has had a number of bumps and blows to his head - hit in the head by another child accidentally with a bat (twice, different kids, different events), falling and banging his head (several times), bumping into things, etc.
I'm really worried that he might develop serious problems in the future because of these incidents and that they may take years to manifest. There isn't anything obviously wrong with him but I can't but worry if there is damage there that will show up sooner or later.
