Sorry to hear about your younger sister Denis. Piling on the best wishes from others here for a great outcome.

24 years ago I passed out at Target, fell back head first onto the concrete floor. Halo skull fracture and impact seizure - I "woke" in the ER that day. Took me out of work for nearly a month So I have some experience here. Consulted with the neurologist who worked on me and others during follow up care. Bottom line is there is still much to learn about the brain and it's many differences between us. He said he has treated folks with damage like mine, generally vehicle/motorcycle related, and some (like me) luckily turn out just fine. He also treated folks with minor bumps to the head who suffered long term/permanent damage.

Consider your sister and family lucky sir. Head injuries are no joke and when we get older the famous “monkey roll” is just a pipe dream.
