What kind of concussions? Knocked out, bleeding from the head, and forced to stay in bed for a few days, or ran head first into door/wall/table and started crying with a mild headache?

I feel there's a start difference between those two, and the article doesn't appear to specify.

Every time my siblings or I had anything anyone considered a concussion. They couldn’t walk in a straight line, were throwing up when standing up. My sister got a concussion from a bad go-cart crash (it went through the barrier and fake wall). She was shaky on her feet for 3days, and had bad bruising all over her face. My brother fell head first over a raised porch railing into rocks, about 5ft. They had to glue the skin back together on his forehead because they couldn’t sew it the edges wouldn’t meet. Ever since he’s plagued by migraines especially when his sinuses are full. I was doing backflips on a trampoline, landed in the “cannon ball” position on the back of my neck/head. This slammed my right knee into my eye socket, giving me a spectacular black eye. But nearly immediately I got intense vertigo, nausea. If I closed my eyes it felt like I was falling, but I felt so tired. This lasted the rest of the day and I had be injured before noon.

Sure my mom might dramatically call a toddlers spill a concussion. But I my experience she only remembers that for like a week maybe. What she remembers and tells doctors and others about years later are the bleeding throwing up kind. Not saying I can tell she had serious concussions, just it would be really weird to report a little head bump and bruise for this kind of thing.
