Neuro Disorders: Stroke

Lobes of the brain

• Frontal Lobe: Motor & Behavior

• Parietal Lobe: Understanding space/position

• Temporal Lobe: Hearing & Understanding

• Occipital Lobe: Visual

Hemispheres of the brain

• Left hemisphere controls the right side of the body’s motor function

• Right hemisphere controls the left side of the body’s motor function

Cerebrovascular Accident (CVA) or Stroke

• Brain Attack

• Medical Emergency

• Time lost = Brain lost

Stroke Recognition

• Importance is to recognize and be fast!!!

• Patient education (BEFAST)

• Multiple types strokes; gotta catch them all

Pathophysiology of Stroke

• Brain cannot store glucose or oxygen

• Disruption in blood flow in or out leads to cerebral tissue death (Infarction)

• Effect depends on: Where, How long, Amount of tissue involved

Clinical Manifestations Impacted By

• Cerebral artery affected

• Area of brain supplied by vessel

• Adequacy of collateral circulation

Types of Strokes

• Ischemic: A clot blocking blood flow to an area of the brain

• Hemorrhagic: Bleeding inside or around brain tissue

Ischemic Strokes: Thrombotic Stroke

• Presentation: Slow, gradual onset of S/S
