Common Neurological and MS disorders and the pathophysiological nature of these issues in adults and children: Concepts of Neurological and Musculoskeletal Disorders Stroke  Cerebrovascular disease is the most frequently occurring neurologic disorder. Any abnormality of the blood vessels of the brain is referred to as cerebrovascular disease includes vessel wall abnormalities and vascular malformations, thrombotic or embolic occlusion, and increased blood viscosity or clotting.  Cerebrovascular disease causes o ischemia with or without infarction and hemorrhage. o The common clinical manifestation is a cerebrovascular accident (CVA) or stroke syndrome. o Hypertension is the greatest risk factor followed by other preventable risks.  CVAs are classified according to the pathophysiology and include ischemic (thrombotic, embolic, and hypoperfusion), lacunar (small vessel disease), and hemorrhagic strokes.  Ischemic strokes result from interruption in brain-blood flow with a core of irreversible ischemia and necrosis or infarction that appears pale (white infarct). o The zone around the infarction has reversible ischemia, is called the ischemic penumbra, and can regain neurologic function, particularly with thrombolytic treatment. o Leaking blood vessels can develop in the infarcted area, resulting in a hemorrhagic transformation (a red infarct) that can be exacerbated by thrombolytic therapy. o Reperfusion injury can occur with ischemic stroke.  Intracerebral hemorrhagic stroke is primarily associated with vessel disease related to hypertension.  Subarachnoid hemorrhage is associated with ruptured aneurysms, arteriovenous malformations (AVMs), or cavernous angioma [Show More]
