Hi, Thank you for your question. Generally, rehabilitation is the only effective way to help you to regain function in better way and prevent from permanent losses. If rehabilitation program is appropriately instituted, most of the stroke patients can regain maximum functions with appropriate therapy, training and support services. For coordinated rehabilitation program a team of a neurologist, a physiotherapist, an occupational therapist and a speech-language pathologist, a nutritionist work together to help you in your recovery. Therefore, I would suggest following the suggestion made by them and recovery will be although slow but most of the functions may be restored. Hope this helps.
The answer to your question depend partly on the area of damage. Maybe yes, and maybe no.
Essentially, the human brain is divided into two halfs, either of which is perfectly capable of handling the chores of the other. There is redundancy. Early in life one part takes over as the "primary" brain. 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.
If the damage from the bleed is in other areas, without redundancy, for example near the pituitary, the situation is more dicey.
