Stroke. Risks, recognition, and return to work.

1. The two major classifications of stroke are ischemic and hemorrhagic. Ischemic strokes account for 75% of all strokes and result from the complete occlusion of an artery. Hemorrhagic strokes, often caused by aneurysm or hypertension, are caused by the rupture of a cerebral blood vessel and bleeding into the surrounding tissue. 2. The signs and symptoms of stroke may include unilateral weakness or paralysis, a sagging of one side of the face, double or blurred vision, vertigo, numbness or tingling, and language disturbances. 3. Management of ischemic stroke may include thrombolytic agents (e.g., heparin, warfarin) if the individual is treated within 6 hours after the onset of symptoms. Diagnostic tests may include, computed tomography scan, transesophageal echocardiagraphy, Doppler ultrasonography, and electrocordiography. 4. Occupational health nurses can be actively involved in helping workers modify their risks for stroke, developing and implementing an action plan if an individual is experiencing a stroke, and facilitating the individual's reentry into the worksite after rehabilitation is completed.
