Neurology - Stroke Management

Overview

What Is a Stroke?

A stroke is a serious medical emergency and occurs when brain cells die within minutes because the blood supply to a portion of the brain is interrupted. There are two main types.  When a blood vessel supplying the brain becomes blocked, usually by a clot, an ischaemic stroke happens. When a blood vessel in the brain bursts, which leads to bleeding into surrounding tissue, this is referred to as a haemorrhagic stroke.

Every second without treatment increases the risk of permanent disability or death and both types require immediate attention. The moment symptoms are recognised, stroke management begins and getting the patient to a dedicated stroke unit hospital as quickly as possible makes all the difference.

Types of Strokes

When a clot blocks an artery feeding the brain, this is known as an ischaemic stroke, which is the majority of cases. The clot can form two ways which may form locally or travel from elsewhere in the body, such as the heart. Haemorrhagic strokes result from a weakened blood vessel that ruptures and are more severe although are less common. They happen often due to uncontrolled high blood pressure or an aneurysm. 

A transient ischaemic attack (TIA) is a temporary blockage that usually resolves on its own and is often referred to as a mini stroke. A TIA is a warning sign from the body for something more serious, even though its symptoms usually disappear within minutes. To prevent an escalation of a full stroke later, anyone experiencing symptoms should seek an immediate medical evaluation.

Recognising early signs saves lives, with the most reliable tool for spotting a stroke remaining the acronym BE FAST. B stands for sudden loss of balance or coordination, with E referring to eyesight changes, such as blurred vision or difficulty seeing out of one eye. F is for facial droop. One side of the face may feel numb or appear uneven when smiling and A indicates arm weakness or drift when both arms are raised. S covers speech difficulties, including slurred words or trouble understanding what others are saying, with T meaning time to call emergency services immediately.

Sometimes symptoms may seem mild or come and go, but this is not an exception and anyone experiencing these symptoms needs urgent assessment. Moving the patient to a stroke clinic or emergency department is not advisable and the safest option would be calling an ambulance. This ensures treatment can begin en route. Timing is important as when delivered within the first few hours after symptom onset, acute stroke management is most effective.

 

The medical team moves quickly when a patient arrives at an NMC facility with a suspected stroke. A neurological examination is performed straight away that assesses consciousness, eye movements, speech, strength and sensation. Brain imaging comes next. A CT scan can tell the difference between an ischaemic and a haemorrhagic stroke within minutes and MRI scans are used to give more detail. They are useful for smaller strokes or more complex cases.

Many conditions can mimic a stroke, such as low blood sugar or infections and to rule these out, blood tests are performed. To check for heart rhythm abnormalities like atrial fibrillation, which is a common cause of clot formation, an electrocardiogram is used. To examine the blood vessels supplying the brain, in some cases, a carotid ultrasound or cerebral angiography is used. Using these diagnostic tools, a stroke specialist can determine the exact cause and location of the stroke, which then guides treatment decisions.

  • Acute ischaemic stroke

  • Haemorrhagic stroke 

  • Transient ischaemic attack (TIA)

  • Cerebral venous sinus thrombosis

  • Stroke secondary to atrial fibrillation

  • Stroke caused by carotid artery disease

  • Post-stroke seizures

  • Stroke-related speech and swallowing disorders

 

Treatment options entirely depend on two main things, which are the type of stroke and how quickly the patient reaches care. The priority is to restore blood flow for ischaemic strokes and the first-line acute stroke treatment for eligible patients is intravenous thrombolysis. This is often called clot-busting therapy and is a medication that must be given within a strict time window, typically up to four and a half hours from symptom onset and dissolves the clot. To save precious minutes, this therapy can be initiated in the CT room itself at NMC. 

For patients who arrive outside this window or have large vessel blockages, a mechanical thrombectomy may be an option This interventional procedure involves threading a small catheter through an artery, usually in the groin, up to the brain which then a stent retriever device removes the clot physically. For carefully chosen patients, this brain stroke treatment can still work up to 24 hours after symptoms start. That gives more people a real chance at recovery.

For a haemorrhagic stroke, the approach is different with controlling bleeding and reducing pressure inside the skull the top priorities. To reverse any blood-thinning effects and to lower blood pressure, medications are given and if the bleeding is severe or caused by a ruptured aneurysm, neurosurgical intervention may be required. Endovascular coiling is a minimally invasive technique where tiny platinum coils are placed inside the aneurysm to seal it off.

When the acute stroke phase is managed, attention turns to rehabilitation. The stroke rehabilitation clinic at NMC provides a structured programme involving physiotherapists, occupational therapists and speech and language therapists. Rehabilitation although begins on the ward, it continues after discharge, either as an outpatient or through home visits. Whether through walking again, returning to work or simply managing daily tasks like dressing and eating, the goal is to help the patient regain as much independence as possible.

 

The stroke team brings together a range of specialists under one roof here at NMC. Consultant neurologists are leading our stroke service, supported by radiologists, neurosurgeons, intensivists and emergency physicians. Specialist stroke nurses are on hand around the clock and a separate team of therapists looks after rehabilitation.

Empathy drives every member of the team as they understand that a stroke affects not just the patient but the entire family. Explanations are key and what treatment was given and what to expect in the days and weeks ahead are discussed with transparency. To monitor recovery, adjust medications and manage risk factors such as high blood pressure, diabetes and high cholesterol, follow-up appointments are scheduled. NMC offers access to this multidisciplinary team across Abu Dhabi, Dubai, Sharjah, Ajman, Ras Al Khaimah, and Al Ain, helping anyone searching for a stroke specialist in the UAE

Frequently Asked Questions

The golden hour is the first hour after symptom onset with treatment given within this window offers the best chance of a good outcome. However, thrombolysis can be given up to four and a half hours, and mechanical thrombectomy up to 24 hours in selected patients.
Many strokes can be prevented. You can reduce the risk by doing things like managing blood pressure, keeping cholesterol in check, controlling diabetes, stopping smoking and maintaining a healthy weight. Where appropriate, atrial fibrillation should be treated with blood thinners. To help identify risk factors before they cause trouble, regular check-ups with a GP are advised.
