3. Types of Stroke Clot (Ischemic) 83% of all cases Result of an obstruction within a blood vessel supplying blood to the brain Due to the development of fatty deposits lining the vessel walls, called atherosclerosis Fatty deposits can cause cerebral thrombosis or a cerebral embolism

12. Behavior Interventions Treat the person with respect Offer praise Give the person choices Be assertive and set necessary limits

13. Personal Experience During my internship in cardiac rehab, we had a patient who had had a stroke prior to her heart attack. When she would come into rehab, she never remembered why she was there. Each day I would tell her to get her folder and I would help her fill out the exercise log. She never wanted to exercise and she had the quickest come backs. Every day we had to help her with her exercise prescription and help her remember what she was to do in rehab.

14. How I Communicated with her… Slow, clear speech Repetition Short explanations but to the point Short reminders on her folder Hugs…in order to make her happy to be there
