In ischemic stroke, there is a block in the brain\u2019s blood vessel which stops blood flow to the brain. Without blood flow, the brain cells start to die. An ischemic stroke is what happens in 80% of stroke cases.<\/li>\n<li>In hemorrhagic stroke, there is a bleed in the brain. This happens in 15% of stroke cases. A bleed usually happens due to high, untreated blood pressure. This bleed too damages the brain cells.<\/li>\n<li>In rare occasions, an aneurysmal rupture can lead to a stroke. When the blood vessels in the brain are weak, they tend to bulge and with the passage of time they rupture, bleeding into the brain.<\/li>\n<\/ul>\n<p><iframe loading=\"lazy\" title=\"#MasterstrokeAgainstStroke Ep 1: Understanding stroke and its types\" width=\"900\" height=\"506\" src=\"https:\/\/www.youtube.com\/embed\/lN5EU4yLz8Y?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen><\/iframe><\/p>\n<h2><strong>Identifying a Stroke<\/strong><\/h2>\n<h3><strong>FAST \u2013 Face, Arm, Speech, Time<\/strong><\/h3>\n<p>The above acronym is something all of us must keep in mind to help us identify a stroke.<\/p>\n<ul>\n<li>Face \u2013 Observe the patient\u2019s face. If the mouth seems deviated to one side or in other words if the smile seems uneven, it is a symptom of a stroke.<\/li>\n<li>Arm \u2013 Ask the patient to lift both arms. If the patient feels weakness in one of the arms, it is another symptom of concern.<\/li>\n<li>Speech \u2013 Listen to them talk. If their words seem slurred, it is another stroke symptom.<\/li>\n<li>Time \u2013 Time is of essence. Even if any one of the above symptoms are observed, it warrants an immediate hospital visit.<\/li>\n<\/ul>\n<p>In a few cases, there are problems encountered with the eyes and balance as well. Hence this requires a slight addition to be made to the above acronym to BE-FAST.<\/p>\n<ul>\n<li>B \u2013 Observe the patient for any balance or coordination issues.<\/li>\n<li>E \u2013 Eye symptoms like blurring or vision loss are also signs of a stroke.<\/li>\n<\/ul>\n<div class=\"also-read\">Also Read: <a href=\"https:\/\/kauveryhospital.com\/blog\/neurology\/be-fast-on-managing-stroke\/\">Be \u2018FAST\u2019 On Managing Stroke<\/a><\/div>\n<h2><strong>Predicting a Stroke<\/strong><\/h2>\n<ul>\n<li>Often, before a stroke happens, there are a few warning signs that might be missed because people are not aware of them. Being aware will help us predict and prevent a stroke.<\/li>\n<li>In the case of an ischemic stroke, a TIA (transient ischemic attack or temporary stroke) might be experienced ahead of the stroke.<\/li>\n<li>During a TIA, the patient will experience weakness, vision loss and speech loss. These symptoms tend to resolve themselves and as a result the patient might ignore these very important warning signs. 35% of such cases suffer a stroke within a year.<\/li>\n<li>In case of a hemorrhagic stroke, the patient will experience severe headache (thunderclap headache) which will resolve itself with 1-2 minutes. However, this headache might be followed by neck pain and sometimes the patient might also experience loss of consciousness.<\/li>\n<li>In some cases, stroke can also cause cognitive, behavioural and emotional changes along with memory problems. In the <a href=\"https:\/\/kauveryhospital.com\/blog\/neurology\/stroke-in-the-elderly\/\">elderly<\/a> especially, these changes tend to be ignored as an inevitable part of aging. However, these are warning signs of a possible stroke and it is best to get the person evaluated.<\/li>\n<\/ul>\n<h2><strong>Treatment Options for Ischemic Stroke &#8211; Thrombolysis and Mechanical Thrombectomy<\/strong><\/h2>\n<ul>\n<li>Treatment for an ischemic stroke differs from a hemorrhagic stroke.<\/li>\n<li>For an <a href=\"https:\/\/kauveryhospital.com\/blog\/neurology\/ischemic-stroke-what-is-it-causes-and-symptoms\/\">ischemic stroke<\/a>, the block which is preventing the flow of blood to the brain needs to be broken down.<\/li>\n<li>Time plays a huge role as bringing the patient to a hospital within 4 \u00bd hours of stroke onset can change the prognosis. Hence these 4 \u00bd hours are rightfully called the golden hours.<\/li>\n<li>Once the patient reaches the hospital, a CT scan will be done and if it is normal, the neurologist will take steps to break the clot to resume blood flow.<\/li>\n<li>There are two drugs for this \u2013 RTPA and Tenecteplase. The exact drug will be decided on by the <a href=\"https:\/\/www.kauveryhospital.com\/doctors\/chennai\/neurology-and-neuroscience\">neurologist<\/a>. This process of clot breakdown with medication is called <strong>thrombolysis<\/strong>.<\/li>\n<li>Thrombolysis will not be done if the patient has high blood pressure, is pregnant, has undergone a recent surgical procedure, is on blood thinners, has suffered recent head trauma or if he\/she has bleeding problems.<\/li>\n<li>When the doctor decides that thrombolysis can be carried out, it is crucial that the drug be administered within 4 \u00bd hours of stroke onset. This is because beyond 4 \u00bd hours, the drug will manifest severe side effects.<\/li>\n<li>After drug administration, 60-70% of the time, the patient will return to near normalcy. In cases wherein the patient does not show improvement, he\/she will be shifted to the cath lab.<\/li>\n<li>In the cath lab, a dye is injected to locate the block.<\/li>\n<li>Once the clot has been localized, using a special catheter, the clot will be removed mechanically by a process called <strong>mechanical thrombectomy<\/strong>. After the clot has been removed, blood flow to the brain will resume.<\/li>\n<\/ul>\n<h2><strong>Keep in Mind<\/strong><\/h2>\n<ul>\n<li>Thrombolysis has to be done within 4 \u00bd hours of stroke onset.<\/li>\n<li>A mechanical thrombectomy can be done for up to 6-12 hours after stroke onset. In some very rare cases, even till 24 hours it is done.<\/li>\n<li>The procedure of mechanical thrombectomy is done in all comprehensive stroke care centres.<\/li>\n<\/ul>\n<h2><strong>As Always, Prevention Is Better Than Cure<\/strong><\/h2>\n<p>Stroke prevention is possible \u2013 all it takes is a little effort. The following lifestyle changes will go a long way towards stroke prevention:<\/p>\n<ul>\n<li>Make healthy diet a part of your lifestyle. Plant based food, fish and poultry products (for non-vegetarians) are recommended.<\/li>\n<li>Be active \u2013 set aside some time for exercise every day. At least 30 minutes a day for 5 days in a week would be ideal.<\/li>\n<li>Quit alcohol and smoking.<\/li>\n<li>Learn to manage stress. Brighten up your workspace and avoid multitasking.<\/li>\n<li>Make sure BP and sugar are within range.<\/li>\n<\/ul>\n<p>Make the above-mentioned changes today to help prevent a possible stroke attack in the future.<\/p>\n<hr \/>\n<p><em><strong>Reviewed by Dr Suresh S Venkita, Group Medical Director, Kauvery Hospitals<\/strong><\/em><\/p>\n<hr \/>\n<p>Kauvery Hospital is globally known for its multidisciplinary services at all its Centers of Excellence, and for its comprehensive, Avant-Grade technology, especially in diagnostics and remedial care in heart diseases, transplantation, vascular and neurosciences medicine.
