So about 5 years ago, someone I knew had a stroke, and incidentally, as soon as we administered a sugar liquid, he came into his senses and we were able to prevent any permanent and lasting damage to his brain. The doctor said that he suffered an Ischemic stroke.<p>Coming back to today, he started showing symptoms of stroke again after all these years - difficulty maintaining balance or comprehending the surroundings. We quickly gave him a glass of sugared water and a spoon of sugar and he was again back to his senses. Now, I find it hard to believe that there is any relation between sugar and the role it plays in alleviating stroke-related symptoms, and I would like to ask an expert's opinion on this.<p>PS: He's a diabetic too.
