Ischemic stroke

A blocked blood vessel in the brain can impair speech, movement, vision and consciousness; timely intervention is vital.

Ischemic stroke occurs when blood flow through a blood vessel in the brain is blocked. Early recognition and emergency treatment may help reduce the extent of brain injury.

When to seek emergency care

If any of the following signs occur, call *3003 immediately — do not wait for a routine appointment:

  • Drooping on one side of the face
  • Sudden weakness in an arm or leg
  • Unintelligible speech or inability to speak
  • Loss of vision
  • Sudden severe dizziness and loss of coordination

What is it?

Stroke is not a matter for a routine appointment. Knowing the exact time the symptoms began is essential for determining the treatment window.

Symptoms

  • Weakness on one side
  • Speech impairment
  • Facial asymmetry
  • Visual impairment
  • Numbness
  • Altered consciousness

Causes & risk factors

  • Atrial fibrillation
  • Carotid artery stenosis
  • High blood pressure
  • Diabetes
  • Smoking
  • High cholesterol
  • Previous TIA or stroke

Diagnosis

Diagnosis does not rely on a single test. Symptoms, risk factors, physical examination findings and investigation results are assessed together.

  • Emergency brain CT or MRI
  • Vascular imaging
  • ECG and heart rhythm assessment
  • Blood tests
  • Neurological examination

Treatment approaches

Treatment is individualized according to disease severity, the patient's overall condition, comorbidities and procedural risk.

  • Emergency stroke protocol
  • Thrombolysis within an appropriate time window
  • Mechanical thrombectomy in selected cases of large-vessel occlusion
  • Secondary prevention
  • Rehabilitation

How we help

At the center, a patient with suspected stroke is referred for urgent neurological and vascular assessment. If there is a large-vessel occlusion, the need for endovascular intervention is considered without delay.

When a procedure may be needed

Mechanical thrombectomy may be needed when a large brain vessel is occluded, the time window is appropriate and imaging findings are supportive.

Patient checklist

  • Record the exact time the symptoms began
  • Do not give medication on your own
  • Call emergency services
  • If you have atrial fibrillation, do not interrupt prescribed treatment

FAQ

If stroke symptoms resolve, is it still an emergency?

Yes. A transient ischemic attack may be a warning of a future stroke.

Can I wait at home if a stroke is suspected?
