Hi, this question is for my own piece of mind. A near concussive impact happened to me 5 days after anaesthesia. I did not have a full blown concussion with symptoms; is it possible for the brain to still undergo the cascade of events of concussion? Does the anaesthesia make that more likely? And would any herbal medication, such as passion flower (along with other herbs), pose any threat to the brain in the same week? What would happen to the brain after all these things? Is there any chance of slight brain damage from these things?
Hi, welcome to Chat Doctor, Concussion (shear-force impact) is described as some violent or abrupt force applied to brain, According to the classic definition, no structural brain damage occurs in concussion.  The clinical presentation might be retrograde amnesia, the second part of your question - anesthesia can commonly cause convulsion, how-ever it depends on type, technique dose.,but no structural brain damage occurs.  Kindly, dont use any medicine or herbal product without consultation to your doctor, Finally, if you are asymptomatic no need to worry!  REGARDS
