Can damaged brain repair itself?

After a traumatic brain injury, it sometimes happens that the brain can repair itself, building new brain cells to replace damaged ones. But the repair doesn't happen quickly enough to allow recovery from degenerative conditions like motor neuron disease (also known as Lou Gehrig's disease or ALS).

What allows the brain to heal itself?

Neuroplasticity is the brain's ability to reorganize itself by forming new neural connections throughout life.

Is brain damage always permanent?

Does sleeping heal the brain?
