A stroke is defined as the rapid onset of neurologic symptoms caused by focal brain, spinal cord or retinal ischemia. It results in rapid loss of nerve function and often causes death or severe disability. A stroke occurs when oxygen-rich blood stops flowing to part of the brain due to a blockage, causing it to be deprived of oxygen and food.
A physiatrist is a doctor who specializes in diseases that affect the brain, spinal cord, nerves, bones, joints, ligaments, muscles and tendons and is responsible for restoring lost abilities due to illness or injury.
Remember that for the proper selection of health professional that treats stroke you must consider the nature, severity and symptoms you are presenting.
