Cardiac arrest, the insult to the brain? |
sister in law had had cardiac arrest ,,they thought it was a blocked artery but i came back clear.. and she has memry lose ,, any help ? does the memorey loss get better whit time ? Cardiac arrest does not necessarily have be to caused by a heart attack, but can also be caused by a life threatening heart rhythm change. Cardiac arrest means that the heart stops effectively pumping blood throughout the body (and thus no oxygen can get to the brain). The brain only has about 4-5 minutes of stored energy, and after this if it does not have oxygen than brain cells can die. Memory loss and sometimes permanent neurological changes are very common post cardiac arrest. If she is walking/talking she is in the minority of people who have survived a cardiac arrest. I do not think so. Since after the cardiac arrest the brain did not get sufficint blood supply within 4 minutes. So the brain of that portion is damaged. |
