Document Summary
Cerebral vascular accidents: cva can also refer to a stroke. Something has happened in the blood supply in the brain. It refers to a severe interruption in the blood supply of the brain. If someone suffocates themselves, their brains can become ischemic. Usually caused by a stroke but can be caused by other things. Infarct: area of the brain that is dead. A person had a cva which resulted in ischemia, and you can see an infarct on the mri. The larger the artery that is blocked, the larger the part of the brain that will be destroyed. Encephalo malacia: this refers to a situation where the blood supply loss is really slow. Not all the neurons are dead, but there is a lot of damage. Most often called by a blockage in the artery. Tia: transient ischemic attack- it is transient (temporary), ischemic (not enough oxygen). A constriction of the muscles that surround the blood vessels.
