A stroke is the rapid loss of brain function(s) due to disturbance in the blood supply to the brain. When you have an ischemic stroke, there is an interruption, or reduction, of the blood supply. Eighty percent of all strokes occur due to ischemia. With a hemorrhagic stroke, there is bleeding in the brain. After about 4 minutes without blood and oxygen, brain cells become damaged and may die. When brain cells are damaged or die, the body parts controlled by those cells cannot function. The loss of function may be mild or severe and temporary or permanent. This depends on where and how much of the brain is damaged and how fast the blood supply can be returned to the affected cells.

Mirror therapy, a treatment technique first described by V.S. Ramachandran for phantom limb pain following amputation, is a form of motor imagery in which a mirror is used to process visual feedback about motor performance of the unaffected body part as it performs various movements. It is primarily used to speed up and improve motor function after stroke and other neurological disorders.
