When the blood flow to the brain is interrupted in any way by a blockage of blood vessels inside the brain or neck, brain cells cannot get oxygen and nutrients that are necessary for them. If this problem is not resolved within a very short time, permanent brain damage occurs. When brain cells die, they cannot be revived and the damage is permanent.

There are two types of stroke: Ischemic stroke and hemorrhagic stroke. Ischemic stroke is a more common type of stroke and occurs when blood flow to the brain is cut off. Hemorrhagic stroke occurs when there is bleeding into the brain or its surroundings.

Strokes can occur at any age, though it is more common in later life. Smoking, high blood pressure, diabetes, heart diseases, and high cholesterol increase the risk of stroke.

Symptoms of a stroke can be very different, but all the symptoms occur all of a sudden. The main symptoms of stroke are as follows:

  • Very severe headache
  • Confusion, confusing people, current time and place.
  • Numbness, weakness or inability to move in any arm, leg, or face.
  • Sudden disruption of speech
  • Loss of vision
  • Loss of balance or inability to do skills requiring coordination.

Brain surgeons have several treatment options upon an early diagnosis of stroke. These include repair of an aneurysm bleeding in the head, removal of blood clots creating blockage in the brain or of plaques that may create blockage inside the brain after separating from carotid artery in the neck.
