CONTINUING MEDICAL EDUCATION (CME)
Topic: STROKE
This week’s CME session on Stroke brought together healthcare teams from Leopards Hill Medical Center, Kabelenga Family Hospital, Lilayi Family Clinic, and Halfway Family Hospital.
STROKE
1.DEFINITION
Stroke is a sudden neurological deficit caused by interruption of blood flow to the brain or bleeding within/around the brain, resulting in brain injury.
2.CAUSES / RISK FACTORS
Major causes
Ischaemia: thrombus or embolus blocking a cerebral artery
Haemorrhage: rupture of a cerebral blood vessel
Important risk factors
Hypertension *
Diabetes mellitus
Dyslipidaemia
Atrial fibrillation
Smoking
Obesity & physical inactivity
Previous TIA/stroke
Carotid artery disease
Excessive alcohol use
3. CLASSIFICATION
A. Ischaemic stroke — ~80–85%
Thrombotic
Embolic
Small-vessel/lacunar
B. Haemorrhagic stroke
Intracerebral haemorrhage (ICH)
Subarachnoid haemorrhage (SAH)
TIA: transient neurological dysfunction due to focal brain/retinal ischaemia without acute infarction.
4. SIGNS & SYMPTOMS
Think BE-FAST:
B – Balance: sudden loss of balance/coordination
E – Eyes: sudden visual disturbance
F – Face: facial drooping
A – Arm: sudden weakness/numbness, especially one-sided
S – Speech: slurred or difficulty speaking/understanding
T – Time: call emergency services immediately
Other features:
Sudden severe headache
Dizziness/vertigo
Difficulty swallowing
Confusion
Loss of consciousness
Seizures, particularly with haemorrhagic stroke
5. INVESTIGATIONS
Immediate
Non-contrast CT brain rapidly distinguishes haemorrhage from most ischaemic strokes
Blood glucose exclude hypoglycaemia, a major stroke mimic
Vital signs + neurological assessment/NIHSS
Additional
FBC, electrolytes, urea/creatinine
PT/INR, aPTT
ECG ± cardiac monitoring
Troponin where indicated
Lipid profile & HbA1c
CT/MR angiography when indicated
Carotid imaging
Echocardiography when a cardioembolic source is suspected
6. MANAGEMENT
•Ischaemic Stroke
Stabilize ABC, oxygen only if hypoxic
Check and correct hypoglycaemia
IV thrombolysis in eligible patients within the appropriate treatment window
Mechanical thrombectomy for selected patients with large-vessel occlusion, often up to 24 hours in appropriately selected cases
Antiplatelet therapy when appropriate and after excluding haemorrhage
Treat fever, glucose abnormalities and complications
Early rehabilitation
•Haemorrhagic Stroke
ABC stabilization
Careful blood-pressure management
Reverse anticoagulation when applicable
Neurosurgical/neurocritical care assessment
Manage raised intracranial pressure
Treat seizures when indicated
Early rehabilitation
⚠️ Do NOT give aspirin or anticoagulation until intracranial haemorrhage has been excluded.
