Thermodynamic Stroke

Stroke occurs when the blood supply to a part of the brain is suddenly interrupted or when a blood vessel in the brain bursts, spilling blood into the spaces surrounding brain cells (National Institute of Neurological Disorders and Stroke, Stroke Information Page, 2013). There are two types of stroke: ischemic and hemorrhagic. An ischemic stroke is caused when there is a blockage in the blood vessels to the brain (AHA/ASA, 2012). Ischemic strokes account for 85% of strokes (Go, Mozaffarin, Roger, Benjamin, Berry, Borden, et al., 2012). A hemorrhagic stroke is caused when an artery is ruptured or leaks blood in the brain (National Center for Chronic Disease Prevention and Health Promotion, Division for Heart Disease and Stroke Prevention, Types of Stroke (2013). Another form of strokes are Transient Ischemic Attacks (TIAs) often referred to as “mini strokes” (AHA/ASA, 2012). These are often warning signs that a stroke could occur if an individual’s lifestyle or risk factors are not modified. During a TIA, there is a temporary decrease in blood supply to the brain; symptoms usually last less than 24 hours before disappearing (NSA, 2012).
Epidemiology
Fifteen million people suffer stroke worldwide each year (World Health Report, 2002). High blood pressure contributes to more than 12.7 million strokes worldwide (WHR, 2002). Europe

About 87% of strokes are ischemic in nature, and are usually caused by the obstruction of an artery by a thrombus or an embolus (Moheet & Katzan, 2011). On the other hand, hemorrhagic strokes which account for 15% of all strokes result from either vascular anomaly or a long history of hypertension. Sixty-five percent (65%) of hemorrhages occur in the basal ganglia-thalamus; 15% in pons. Hemorrhagic stroke is usually progressive and deadly and can evolve over hours to days (Mayo Clinic,
