If you are right-handed the left
half of the brain
is primary. If left
-handed the right side is primary. When one has a stroke and one half of the body loses tone, it is the opposite side where the stroke is. Right face paralysis means left brain involvement.
If the damage is to one half the likelihood is that the other half can, with a lot of work, completely regain lost physical abilities, such as handwriting, or language.
Memories, on the other hand,will probably be lost completely.
