Self-actualization, according to Maslow, represents the growth of an individual toward fulfillment of the highest needs. Maslow argues that only high acheivers are self-actualizers, but we are all in fact capable of self-actualization.
In a thrombotic stroke, a blood clot (thrombus) forms inside one of the brain's arteries. The clot blocks blood flow to a part of the brain. This causes brain cells in that area to stop functioning and die quickly.
A thrombus itself (even if it does not completely block the blood vessel) can lead to an embolic stroke (see below) if the thrombus breaks off and travels in the bloodstream, at which point it is called an embolus. Two types of thrombosis can cause stroke: Large vessel disease involves the common and internal carotid arteries, the vertebral artery, and the Circle of Willis.
