Final answer:
Ischemic strokes are more frequent and are caused by a thrombosis or an embolic occlusion of a cerebral blood vessel, resulting in a constraint of blood flow to the brain. Depending on the severity of the stroke and how quickly treatment is provided, the symptoms may be temporary or permanent. Rehabilitation with therapy may significantly improve functioning.
Step-by-step explanation:
Stroke is a complex and devastating disease, constituting the second leading cause of death worldwide and the leading cause of acquired disability in adults (Brouns, 2009; Lloyd-Jones, 2009; Moskowitz, 2010). Ischemic strokes are more frequent and are caused by a thrombosis or an embolic occlusion of a cerebral blood vessel, more frequently the middle and anterior cerebral arteries, or a general hypo-perfusion, all of which result in a constraint of blood flow to the brain, reducing the delivery of substrates, particularly oxygen and glucose, and ATP production (Dirnagl, 1999; Doyle, 2008; Lloyd-Jones, 2009). Depending on the severity of the stroke and how quickly treatment is provided, the symptoms may be temporary or permanent. Rehabilitation with physical, occupational, speech, or other types of therapy may significantly improve functioning.
