Hi Doc, my father had clot in middle brain, he is diabetic as well, we were able to take him to hosp. in due course of time post his stroke at 12.30am , he slept at 12.15am ... at 2.45am doctor at max hospital got a consent signed and gave him medicine which is approx 60k, we agree for that since 10% chances were there for bleeding, 30% for slight revival and 60% for stagnation... post this medicine , now its 3rd day, he is able to move his right hand n leg, can walk a bit but not able to speak properly .. say yes , no, ok and it looks like he is not able to recall previous instances to the 100% satisfaction, he worked in govt. deptt but on asking he said i worked in private, dont remeber where he live, colour recognistion is not there... green colour , he said royal blue... pls help and suggest what is in store for in future.
