Study Notes
Stroke
Ischemic Stroke
- Accounts for approximately 87% of all strokes
- Caused by blockage of blood vessels supplying the brain, resulting in reduced blood flow and oxygen supply
- Can be caused by:
- Thrombosis (blood clot forms in the brain)
- Embolism (blood clot forms elsewhere in the body and travels to the brain)
- Atherosclerosis (plaque buildup in blood vessels)
- Symptoms:
- Weakness or numbness in the face, arm, or leg
- Confusion or trouble speaking
- Difficulty seeing or understanding
- Dizziness or loss of balance
- Severe headache
Hemorrhagic Stroke
- Accounts for approximately 13% of all strokes
- Caused by bleeding in the brain, resulting in damage to surrounding brain tissue
- Can be caused by:
- High blood pressure
- Aneurysms (weakened blood vessels)
- Arteriovenous malformations (abnormal connections between blood vessels)
- Blood vessel ruptures
- Symptoms:
- Severe headache
- Nausea and vomiting
- Confusion or loss of consciousness
- Weakness or numbness in the face, arm, or leg
- Seizures
Stroke Prevention
- Lifestyle modifications:
- Maintaining a healthy weight
- Engaging in regular physical activity
- Eating a balanced diet
- Quitting smoking
- Limiting alcohol consumption
- Managing underlying health conditions:
- High blood pressure
- Diabetes
- High cholesterol
- Atrial fibrillation
- Medications:
- Antiplatelet agents (e.g., aspirin)
- Anticoagulants (e.g., warfarin)
- Blood pressure medications
Stroke Diagnosis
- Physical examination:
- Assessing neurological function
- Checking for signs of stroke (e.g., facial droop, arm weakness)
- Imaging tests:
- Computed Tomography (CT) scan
- Magnetic Resonance Imaging (MRI)
- Computed Tomography Angiography (CTA)
- Magnetic Resonance Angiography (MRA)
- Other diagnostic tests:
- Electrocardiogram (ECG) to rule out cardiac conditions
- Blood tests to rule out underlying conditions (e.g., diabetes, infections)
