<s>[INST] My cousin is 17 and suffered a stroke this morning around 8am. She s. Having brain surgery as we speak and they say she won t ever be able to speak again and they can t get the blood clot out of her brain. My question is what are her chances of surviving this? And what would cause a blot clot on a 17 year old? [/INST] Hello, Chances of survival depend on the size, location of the hemorrhage. At that age, the hemorrhage is caused mostly by vascular malformations. Hope I have answered your query. Let me know if I can assist you further.
