My nephew,11 years old had ischemic stroke in his left brain 2 months ago,with minor visible symptoms but he cant concentrate much on studies and cant memorize much he learnt in school.can he recover?

He can : Improve with lots of patience and help. Hope the school and parents are there providing that support

Yes!: I'm an adult cardiologist, so this question may be better fielded by a peds cardiologist. However, in general we see recovery stretching out over 6-12 months before one is left with what one has for good. I'd say his youth gives even greater plasticity and hence recoverability potential. Let him know the whole medical community is rooting for him!

Yes, very likely: Children tend to have higher potential for recovery than adults, and he can certainly benefit from both speech and occupational therapies. But, need to know why this occurred and how to prevent future problems.
