JAPAN 2 Lecture Notes - Lecture 17: Thrombus, Synaptic Plasticity, Dura Mater
Document Summary
Tia (transient ischemic attack) a vessel supplying blood to the brain is obstructed. It accounts for about 87 percent of all strokes. Fatty deposits can cause two types of obstruction: Cerebral thrombosis is a thrombus (blood clot) that develops at the fatty plaque within the blood vessel. Cerebral embolism is a blood clot that forms at another location in the circulatory system, usually the heart and large arteries of the upper chest and neck. Part of the blood clot breaks loose, enters the bloodstream and travels through the brain"s blood vessels until it reaches vessels too small to let it pass. A main cause of embolism is an irregular heartbeat called atrial fibrillation. It can cause clots to form in the heart, dislodge and travel to the brain. Silent cerebral infarction (sci), or silent stroke, is a brain injury likely caused by a blood clot that interrupts blood flow in the brain.
