Brain damage coma can/will occur after oxygen deprivation to brain cells. Depending on what part of the brain has damaged cells and damaged is usually localized to a specific region. Expect effects if the damage is to the left side and that typically causes problems with speech and language, and the right side may interfere with the ability to express emotions or interpret what one sees. Damage with either side can cause physical impairment of the opposite side of the body.
It seems regardless of what the region of damage there would be memory loss but more likely the left side brain cell damage and that is what your friend is experiencing. There could be some return to normal functionality as the normal flow of bood to heart cells can be oxygenated with newly developed pathways.
Thank you for sharing, and if you have any further questions or comments you are welcome to respond. Take care.
Knowledge of the brain has increased a lot in the last decade. It is known that when a part of the brain is damaged, other parts will attempt to take over. It takes time, because millions of connections have to be made/broken to get the best solutions, just like a developing baby does. It was once believed that the time limit for improvements was 1-2 years, but this has been proved incorrect on many occasions now. It appears that the largest recovery of the brain occurs within the first 6 months to a year, and then it continues for many years, but at a slower pace. My Wife had a large stroke and her memory was a mess for a few months, but it eventually recovered. I found that it was beneficial to show them reminders, such as photos or videos of family etc. It seemed to help get those connections remade a lot quicker. Older memories are more secure and tend to be the last we lose, which is why many people go back to their childhood when they have brain trauma. The more we use a memory, in other words think about it, the more permanent it becomes. Recent memories will gradually return. Imagine pictures on a computer where the data is all over the hard drive, but the index has been corrupted or deleted. You would need a program to recreate the index so you could generate the pictures again. This is what the brain is doing, linking millions of fragments and trying to get the right connections. This is why continual chatting and photos with reminders make its job so much easier.
:) thanks so much for replying. the doc says he is improving now but his blood is still not thin enough. he said he needs at least 3.1 but his blood is 1.9. what do those numbers mean??
The numbers you have lised refers to the INR numbers and reflects the time it takes for blood to clot (prothrombin time [PT]). The accepted range is 2-3, and generally any time less than 2 means the blood is too thin (slow clotting time) and higher than 5 is a risk of excessive bledding..
Hope this helps, and I wish your friend well going forward. Take care and thanks for the response.
yea i hope so too.
thanks so much! :D
hey. how r u guys doin?
I have another question to ask. the docs said my friend's heart is a bit bigger than it used to be. Why is that? and he has been having some pain again on his heart. what is happening?
