What is a Stroke? Also termed ‘brain attack’, Stroke is caused by the lack of blood supply to the brain, usually because of the formation of a clot. Brain cells become inactive due to a shortage in the supply foxygen and nutrients. This may leave a person partially or completely paralysed. Stroke affects one in six persons in their lifetime. What are the risk factors of Stroke? Anyone can be vulnerable, irrespective of age, race or gender. But people with the following conditions are at a higher risk of suffering a Stroke:
  • High blood pressure
  • Obesity
  • Physical inactivity
  • High cholesterol
  • Diabetes
  • Tobacco abuse
  • Alcohol abuse
  • Smoking
What are the types of Stroke? The two main types:
  • Ischaemic Stroke: This happens due to the blockage of blood vessels, which reduces the brain’s blood supply.
  • Haemorrhagic Stroke: It occurs due to the rupture of blood vessels.
What are the symptoms of a Stroke? The symptoms include sudden:
  • Numbness or weakness of the face, arm or leg, especially on one side of the body.
  • Confusion, trouble speaking or understanding.
  • Severe headache without a known cause.
  • Trouble seeing from one or both eyes.
  • Trouble walking, dizziness, loss of balance or coordination.
A person showing one or some of the above symptoms should be rushed to the hospital immediately. How is Stroke diagnosed? It is diagnosed through the help of physical examinations and tests. Imaging studies such as Computerized Tomography (CT) and Magnetic Resonance Imaging (MRI) help in diagnosing Stroke. How is Stroke treated? Medical treatment: It can be treated with drugs that dissolve blood clots obstructing blood flow to the brain. Surgical treatment: If a clot does not dissolve by medicine, surgical intervention is required to remove the clot from the brain. Immediate treatment can save victims from disability and increase their chances of successful recovery. But one of the biggest obstacles to emergency treatment is most people don’t know they are having a stroke. What disabilities can result from a Stroke? Besides being a life-threatening condition, Stroke can affect the entire body, causing paralysis. Brain cells die during Stroke and functions controlled by that area of the brain can be lost such as speech, movement and memory. What’s the importance of rehabilitation? Stroke is a disaster for patients, mentally and physically. A Stroke patient needs prolonged rehabilitation in returning to normal life. A combined team of physiotherapists, psychologists and psychiatrists play a pivotal role in a Stroke patient’s recovery.
