<p class="bodytext">A former Karnataka CM who recovered from a stroke said he had a ‘third birth’ and highlighted the importance of the ‘golden hour.’ He couldn’t be more right. A stroke is your brain’s equivalent of a heart attack. Referred to as brain attack, a stroke is also called a cerebrovascular accident. This can happen when blood vessels are blocked or because of bleeding due to a rupture of a blood vessel in the brain.</p>.<p class="bodytext">Strokes are a life-threatening emergency, and immediate medical attention is critical to prevent permanent damage or death.
