Blood flow: A stroke is an alteration of blood flow to the brain resulting in a loss of tissue and possible loss of function. It can be categorized in many ways but ultimately is a disease event related to the cerebral circulation. Blockage and rupture of arterial components are commonly described but venous pathologies can also cause stroke.

Damage to brain: A stroke is generally term referred to impairment or loss of function of part of the brain. This happens when blood supply to that part of the brain is interrupted due to a blockage resulting from plaque build up and/ or blood clot. Also rupture of blood vessel causing bleeding in the brain can result in stroke.
