World Stroke Day !

On World Stroke Day, let’s create awareness on how to recognise symptoms of a stroke, risk factors and treatment options.

Strokes are leading causes of death and permanent disability worldwide.

In a stroke, a part of the brain doesn’t receive  sufficient blood or oxygen and as result functioning  of the corresponding body part gets affected.

Strokes are of 3 types, Transient Ischemic attack, Hemorrhagic Stroke and  Ischemic Stroke.

In a Transient ischemic stroke, a blood clot temporarily stops the blood flow from reaching the brain, 

In an Ischemic stroke, a blood clot stops blood flow to the brain. This can be due to a clot travelling from another part of the body to the brain.

In a hemorrhagic stroke, a blood vessel spills or ruptures, causing a leak.

Symptoms of a stroke are usually all neurological, affecting speech, movement and balance.

Usual Stroke symptoms are :

  • Loss of balance
  • Loss of consciousness
  • Dizziness, Vertigo, with or without nausea
  • Confusion, inability in understanding speech are often symptoms too.

Are there any factors, which increase risk of stroke ?

  • Several life style factors contribute to increasing risk of stroke
  • Obesity or excess weight
  • Hypertension or High Blood pressure
  • Diabetes
  • History of Heart Disease
  • Sleep Apnea
  • Sedentary lifestyle, lack of exercise and adequate physical activity
  • Alcoholism

What to do when you spot a stroke victim ?

A Stroke can be completely reversible if treated well in time.  The time window for treatment is usually not more than a couple of hours from onset of symptoms.

Time is of essence for a stroke victim as  many as 32000 cells die every minute of delay, leading to irrepairable damage with every minute of delay.

A CT scan or an MRI are first diagnostic tests and based on whether it is a clot that can be surgically removed or  needs to be dissolved, or a leak or rupture of blood vessels, a neurologist or a neurosurgeon take over.
