Thank you for your query.
I hope there is no reason to worry.The gliotic focus is a mild scarring of the brain that has probably resulted due to the previous bleed.It has no clinical significance and has not selectively affected the memory. She seems to be absolutely fine.her headache maybe due to migraine
.You need not be at all worried about the MRI
scan.Talk to your childs teacher about the maths problem and i am sure she will sort it out fast.I hope this answers your query.Wish you a merry Christmas ahead.
