PSYB65H3 Lecture Notes - Subdural Hematoma, Transient Ischemic Attack, Dura Mater
Document Summary
Blockages of vascular supply / blood flow. Different kinds of blockages: cerebral vascular accidents. Something happened in blood supply of brain. Stroke: subtle differences, severe interruption of blood supply to brain. Brain is not getting enough oxygen / glucose. Usually as a result of stroke or blockage. Can also occur via carbon monoxide poisoning / heart attack. Area of the tissue that is dead / dying. The larger the artery the larger area of brain that will be destroyed: encephalo malacia. Slow gradual constriction of artery that leads to lower amounts of blood supply to critical areas of the brain. Cause of some cases of dementia: transient ischemic attack. Ischemia lack of oxygen / glucose to brain. Brain does not die temporary malfunction of brain processes. Blockages that form elsewhere in the body, breaks off and lodges somewhere else. Different types of bursting: cerebral hemorrhage. Can be life threatening depending on which blood vessel bursts.
