It depends on how extensive the damage is, and whether there are nearby areas of the brain that can take over the damaged areas (when given suitable training).
- A major factor in the extent of the damage is how quickly the patient can be taken to hospital, diagnosed and given suitable treatment. The brain is very oxygen-hungry, and an hour can make a big difference to the amount of damage.
- Physiotherapy and similar rehabilitation can help with recovery, if the damage is not too extensive, and the rehabilitation is affordable
