Which side of brain is worse for stroke?

Can brain repair itself after stroke?
Fortunately, damaged brain cells are not beyond repair. They can regenerate — this process of creating new cells is called neurogenesis. The most rapid recovery usually occurs during the first three to four months after a stroke. However, recovery can continue well into the first and second year.
