Provisional diagnosis of Acute Ischemic Stroke secondary to occlusion of the M1 was made. Trigeminal neuralgia (TN), also called tic douloureux, is a chronic pain condition that affects the trigeminal or 5th cranial nerve, one of the most widely distributed nerves in the head. A typical stroke is the result of blood flow being blocked from part of the brain, and when the brain is deprived of blood and oxygen, the cells begin to die. When a stroke is considered to be massive, it can result in paralysis of one side of the body, an inability to speak, memory loss, coma, or even death. The pathophysiology of stroke is complex, and involves excitotoxicity mechanisms, inflammatory pathways, oxidative damage, ionic imbalances, apoptosis, angiogenesis and neuroprotection. This is where signs and symptoms of a stroke occurs but last only a few minutes to hours and resolves. They happen when a blood clot blocks the flow of blood and oxygen to the brain. INTRODUCTION.

It represents the second leading cause of death and a major cause of disability worldwide. (All other strokes are caused by abnormalities of arteries carrying blood to the brain). The clot might block an artery and lead to sudden, severe myocardial … However, the mechanism underlying ITP-related ischemic stroke (ITP-IS) has not been fully clarified. Meerwaldt R, Slart RH, van Dam GM, Luijckx GJ, Tio RA, Zeebregts CJ. In some cases, acute occlusion of a vessel unaffected by atherosclerosis may occur because of a hypercoagulable state. A cerebrovascular accident (CVA), an ischemic stroke or “brain attack,” is a sudden loss of brain function resulting from a disruption of the bloodsupply to a part of the brain. Local EMS arrived on the scene within 15 minutes, recognized the signs of stroke, and requested flight transport to a comprehensive stroke center (CSC). Hematoma expansion occurs in a large subset of patients and is a predictor of poor outcomes. Stroke, Its Pathophysiology and Nursing Management Technique. There are two main types of stroke: ischemic, due to lack of blood flow, and hemorrhagic, due to bleeding. Just as strokes have many effects, they also have many causes. Risk factors for brain stem stroke are the same as for strokes in other areas of the brain: high blood pressure, diabetes, heart disease, atrial fibrillation and smoking.
