1. Disorders of the Brain

2. Concussion
Slight brain injury
no permanent damage

3. Contusion Nervous tissue destruction occurs
nervous tissue does not regenerate

4. Cerebral Edema Swelling from the inflammatory response
May compress and kill brain tissue

5. Cerebrovascular Attack
Commonly called a stroke
Result of ruptured blood vessel supplying a region of the brain
Brain tissue supplied with oxygen from that blood source dies
Loss of some functions or death may result

6. CVA Thromboembolic stroke- artery is blocked
Hemorrhagic stroke- usually due to aneurysm, artery ruptures
Hemiparesis- paralysis of one side of the body

7. Transient Ischemic Attack
Temporary brain ischemia
restriction of blood flow
Numbness, temporary paralysis, impaired speech
Red flag of CVAs

8. Alzheimer’s Disease Progressive degenerative brain disease
mostly seen in elderly
structural changes in the brain include abnormal protein deposits and twisted fibers within neurons
victims experience memory loss, irritability, confusion, and ultimately, hallucinations and death

9. Multiple Sclerosis Myelin sheath around fibers are gradually destroyed
Person loses muscle control
becomes increasingly disabled
autoimmune disease
