Stroke Know the Causes and the Risk Factors

A stroke, also known as a brain attack, occurs when blood flow to the brain is interrupted. An emergency has arisen. For the brain to function regularly, it needs a stable flow of oxygen and nutrients. It can be problematic if the blood supply is cut off, even briefly. After only a few moments without blood or oxygen, brain cells start to deteriorate. Brain activity is lost when brain cells are destroyed. It?s possible that you will not be able to perform tasks that require that section of your brain. Anyone can experience a stroke at any moment. But despite all this, there are many types of stroke treatment available nowadays as it is now a common problem.

The Causes of a Stroke

When flow of blood to your brain is interrupted or blocked, a stroke occurs. Ischemic and hemorrhagic strokes are the 2 types. 

  • Hemorrhagic stroke – Whenever a blood vessel in your brain breaks, blood seeps into the surrounding tissues, causing this. Pressure develops in the adjacent brain tissue during a hemorrhagic stroke. This results in considerably greater harm and annoyance.
  • Ischemic stroke – The most typical kind of stroke is this one. When a significant blood vessel in the brain is stopped, it occurs. A blood clot could block it, or the growth of lipid and fatty deposits may impede it. The accumulation is known as plaque.

The Risk Factors for Stroke

A stroke can occur to anybody at any time in life. But if you have particular risk factors, your chances of suffering a stroke rise. While some stroke risk factors have stroke treatment and can be altered or controlled, others cannot.

  1. The risk of stroke factors that are modifiable, treatable, or controlled medically include:
  • Elevated blood pressure – Blood veins (arteries) that provide the brain with blood can get damaged if blood pressure is 140/90 or greater.
  • Heart illness – The second-largest risk factor for stroke and the leading cause of death among stroke patients is heart disease. Several of the risk factors for heart disease and stroke are similar.
  • Diabetes – Diabetes increases a person?s risk of stroke compared to anyone without diabetes.
  • Smoking – Your chance of having an ischemic stroke nearly doubles if you smoke.
  • Background of TIAs ? Mini-strokes are another name for TIAs. The signs are similar to those of a stroke. However, they disappear quickly. If you?ve had one or more TIAs, your risk of having a stroke is almost ten times higher as compared to someone your age and gender who has never experienced one.
  • High level of red blood cells – The blood hardens and becomes more likely to clot as the number of red blood cells significantly increases. This enhances the chance of stroke.
  • High blood fats and lipids ? A blockage of plaque in the arteries can affect atherosclerosis, which is the dilation or tightening of the arteries. Layers of calcium, lipids, and fatty materials are known as plaque. Blood flow to the brain could be reduced by plaque accumulation on the interior of artery walls. 
  • Excessive drinking – Your blood pressure increases if you consume more than two drinks daily. Stroke risk can arise from binge drinking.
  • Illicit drugs – Using intravenous (IV) drugs increases the risk of blood clot-related strokes (cerebral embolisms). Cocaine or other narcotics have been strongly associated with heart attacks, strokes, and numerous other cardiac problems.
  • Irregular heartbeat – Some kinds of cardiac disease can boost your risk for stroke. Having an abnormal heart rhythm (atrial fibrillation) is the most strong and most easily treated heart risk factor for stroke.
  • Structural anomalies in the heart – Long-term (chronic) heart disease can result from valvular heart disease, which affects the heart?s valves. Over age, this can enhance your risk for stroke.
  1. Risk factors for stroke that do not have any stroke treatment and can?t be changed include:
  • Old age – Your likelihood of getting a stroke increases more for each year of your life from the age of 55.
  • Race – Compared to white people, African-Americans are far more likely to die from a stroke or become disabled. This is partially attributable to the higher prevalence of high blood pressure in the African-American community.
  • Gender – Men are more likely to experience a stroke, but more women than men pass away due to it.
  • Past stroke incidence – Your chance of getting other increases after one stroke.
  • Genes or heredity – People with a genetic background of stroke are more likely to suffer a stroke.

Treatments for the Stroke

Hemorrhagic and ischemic strokes require different stroke treatments since they have different physiological effects and underlying causes.

  • Hemorrhagic stroke – Hemorrhagic strokes can be caused by blood spilling into the brain. The aim of treatment is to stop the bleeding and release the strain on the brain. Taking medications to lower brain pressure, regulate blood pressure throughout, stop seizures, and stop any rapid blood vessel tightness is frequently the first step in treatment.
  • Ischemic stroke – The cause of an ischemic stroke is blocked or constricted arteries. The goal of treatment is often to improve the blood flow to the brain. Taking medications to dissolve existing clots and stop new ones from developing is the first step in treatment. A doctor may prescribe blood thinners like aspirin or a syringe of TPA. Another choice is an angioplasty, which stops the artery from shrinking once more.

This summarizes the causes, risk factors, and stroke treatments. Hope this helps increase your knowledge about the same.
