What is a stroke?

A stroke occurs due to occlusion of the blood supply to part of your brain. Therefore, the affected part of the brain can be destroyed due to lack of blood, oxygen, and nutrients. Symptoms of a stroke have a sudden onset, and they depend on the part of the brain, which has affected.

  • Slurring of speech
  • Confusion
  • Visual impairment
  • Headache
  • Difficulty speech
  • Numbness of the part of the body

What are the types of stroke?

Ischaemic stroke
Ischaemic stroke occurs when one of the arteries leading to or in your brain is blocked by a blood clot.

Haemorrhagic stroke
This occurs due to rupture of one of the arteries in the brain and bleeding into the brain.


What is TIA?

Transient ischaemic attack (TIA) or ‘mini-stroke’ occurs when one of the arteries in the brain is blocked for a short period. Symptoms of TIA are similar to stroke and disappear within 24 hours.
