3 Risk factors for stroke include: advanced age hypertension * previous stroke diabetes high cholesterol cigarette smoking

4 Three types: thrombotic embolic ischemic hemorrhagic

5 Thrombotic stroke ischemic stroke caused by thrombosis a thrombus (blood clot) usually forms around atherosclerotic plaques causes occlusion of the vessel

6 Large vessel disease - atherosclerosis - inflammatory diseases (Takayasu arteritis, giant cell arteritis, vasculitis...) Small vessel disease - branches of the circle of Wilisi, middle cerebral artery...

7 What type of anemia can we associate with thrombotic stroke?

8 Sickle cell anemia

9 Diagnosis neurological examination

10 CT scans MRI scans Doppler ultrasound arteriography

11 Treatment removing blood clot from the vessel by breaking clot fast reaction → blood flow restored → smaller number of brain cells die

12 How can we break a clot?

13 thrombectomy - mechanical thrombolysis – using drugs

14 Epidemiology stroke could soon be the most common cause of death worldwide "stroke belt" in southeastern U S 95% of strokes occur in people age 45+, and two-thirds of strokes occur in the over-65 group
