My grandpa is 60 years old. Two months ago he suffered with brain stroke. Quickly he is taken to hospital and doctors gave an anti clot injection worth 50000rs. He came back to normal by that day evening. My question is what steps he should take to prevent getting a stroke again? What to eat and what not to eat? Is it possible for any damage to his brain due to his first stroke? Do brain cells die during a stroke? He is a smoker cum alcoholic occasionally. Both are occasional not regular.
