Study Notes
Ischemic Stroke
- Accounts for approximately 87% of all strokes
- Occurs when a blood vessel in the brain becomes blocked, reducing blood flow and oxygen to the brain
- Causes:
- Thrombosis (blood clot forms in the brain)
- Embolism (blood clot forms elsewhere in the body and travels to the brain)
- Atherosclerosis (plaque buildup in the blood vessels)
- Symptoms:
- Sudden weakness or numbness of the face, arm, or leg
- Sudden confusion or trouble speaking
- Sudden trouble seeing in one or both eyes
- Sudden severe headache
- Sudden loss of balance or coordination
Hemorrhagic Stroke
- Accounts for approximately 13% of all strokes
- Occurs when a blood vessel in the brain ruptures, causing bleeding in the brain
- Causes:
- High blood pressure
- Aneurysms (weakened blood vessels)
- Arteriovenous malformations (abnormal connections between blood vessels)
- Blood vessel malformations
- Bleeding disorders
- Symptoms:
- Sudden severe headache
- Nausea and vomiting
- Confusion or loss of consciousness
- Seizures
- Weakness or numbness of the face, arm, or leg
Stroke Diagnosis
- Physical examination:
- Assessing neurological function
- Checking for signs of stroke, such as facial droop or arm weakness
- Imaging tests:
- Computed Tomography (CT) scan
- Magnetic Resonance Imaging (MRI)
- Angiography (to visualize blood vessels)
- Laboratory tests:
- Blood tests to check for bleeding disorders or blood sugar levels
- Electrocardiogram (ECG) to check for heart problems
Stroke Prevention
- Lifestyle modifications:
- Maintaining a healthy weight
- Exercising regularly
- Quitting smoking
- Reducing alcohol consumption
- Managing stress
- Medical interventions:
- Controlling high blood pressure
- Managing diabetes
- Lowering cholesterol levels
- Taking anticoagulant or antiplatelet medications
- Screening for risk factors:
- High blood pressure
- Diabetes
- High cholesterol
- Atrial fibrillation (irregular heartbeat)
Stroke Rehabilitation
- Goals:
- Regaining physical function and mobility
- Improving cognitive function and memory
- Enhancing communication and speech
- Managing emotional and psychological changes
- Therapies:
- Physical therapy (PT)
- Occupational therapy (OT)
- Speech therapy
- Cognitive therapy
- Medications to manage stroke-related symptoms
- Rehabilitation settings:
- Inpatient rehabilitation facilities
- Outpatient rehabilitation programs
- Home-based rehabilitation programs
