My daughter blacks out

what might cause my 10 y.o daughter to black out? Since she was perhaps 5 y.o., we have noticed she falls out of chairs for no reason while just sitting--noticed it happens maybe 3-8 times/year. She acts confused or perhaps momentarily catatonic when it happens, not even sure she realizes what happened. It never ooks like she's actually fainted/lost consciousness. Now she's fainted for the first time during her last 10 minutes of basketball--not sure it's even related. (there is a blood clotting genetic discorder that runs in various family members plus I have normal but low blood pressure) Any insight? Should I be concerned?

Hi there. You need to be concerned as these black outs in your daughter might be epilepsy, if she doesn’t lose consciousness these could be absence seizures or petit mal epilepsy where the child is apparently awake and there with eyes open but not able to understand anything and actually undergoing an epileptiform activity. Only an EEG recording done at that time can provide evidence of seizure. Consult a neurologist immediately and let him do an EEG, neuro physiological study. Once it is proven she will need to take anti epilepsy drugs. Take care.
