A stroke can be caused by two different ways in which blood flow to the brain is limited. The first is a blood clot. When a blood clot blocks an artery, blood cannot move up into the brain. This blood is oxygen-rich and provides the brain with the nutrients it needs to survive. Without these nutrients, brain cells cannot live. The second way in which the blood supply can be cut off is through the rupture of a blood vessel. If a blood vessel breaks, then the blood will flow out into the body instead of up into the brain. Like a blood clot, the rupture of a blood vessel limits the flow of blood into this vital organ, causing its cells to die.
As brain cells begin to die, seniors will experience a loss
of certain capabilities. For instance, their speech or movement may become
impaired. If blood flow is not restored to the brain quickly enough, the damage
done to the cells may prove irreparable. This means that seniors can face
permanent damage to their ability to speak and move. Additionally, if a certain
part of the brain is affected, elderly individuals may lose their memory.
The extent of the damage caused by a stroke is dependent
upon several factors. First and foremost, the location of the event will
determine which parts of the brain are impacted. Furthermore, the amount of
time that it takes for individuals to receive medical assistance plays an
integral role in the ability of healthcare professionals to restore function to
affected parts of the brain. By understanding what is taking place, you can
better get your senior the medical assistance they need.
