Stroke

A medical emergency where blood flow to part of the brain stops, and every minute counts. We handle recovery and preventing another stroke.

At a glance

What it is

Loss of blood supply to part of the brain — from a blocked artery (ischaemic) or a burst vessel (haemorrhagic).

Emergency signs

Face droop, arm weakness, speech difficulty — call an ambulance immediately. Time is brain.

What the clinic does

Post-stroke rehabilitation, spasticity management, secondary prevention, and long-term follow-up — not the acute admission.

What stroke is

A stroke happens when the blood supply to part of the brain is interrupted or reduced, so brain cells stop receiving oxygen. Cells die by the minute — every minute of delayed treatment loses roughly 1.9 million neurons.

There are two main types. The great majority are ischaemic (an artery blocked by a clot). A smaller share are haemorrhagic (a vessel bursts and blood enters the brain tissue). The symptoms often look the same at the start, but the treatment paths in the first hours are opposite — which is why a scan is done immediately in hospital before any drug is given.

The most valuable minute in the whole illness is the one before the ambulance arrives. Every clinic visit after that is downstream — worth doing well, but downstream.

Two types of stroke

The two look similar clinically but are managed very differently in the acute phase — a scan in the emergency department decides which is which.

Type A

Ischaemic stroke

  • ~85% of strokes; artery blocked by clot or embolus.
  • Treatment: thrombolysis and/or thrombectomy within the therapeutic window.
  • Long-term: antiplatelet therapy, blood-pressure control, cholesterol management.

Type B

Haemorrhagic stroke

  • ~15% of strokes; a vessel bursts, blood floods brain tissue.
  • Treatment: blood-pressure reduction; neurosurgical evacuation in selected cases.
  • Long-term: strict BP control, avoid anticoagulants, address any underlying vascular malformation.

Key facts

01 FAST — Face droop, Arm weakness, Speech difficulty, Time to call — is the public-facing recognition tool. Anyone can use it.
02 Sudden severe headache with vomiting or altered consciousness suggests haemorrhagic stroke and is a same-minute emergency.
03 Rehabilitation started within the first 24–48 hours after the acute event improves outcomes measurably.
04 Secondary prevention — controlling blood pressure, cholesterol, diabetes, and atrial fibrillation — reduces recurrence risk by more than half.
05 Depression after stroke is common and undertreated; screening at every follow-up matters.

How we treat stroke recovery

The clinic sees stroke patients after the acute admission — for rehabilitation, spasticity management, and secondary prevention. Every plan combines interventions from the four groups below, weighted to the patient's residual deficit.

Rehabilitation

Restoring function

  • Structured physiotherapy programme
  • Occupational therapy for daily living
  • Speech and language therapy where indicated
  • Gait retraining

Spasticity management

Managing tone and contracture

  • Botulinum toxin for focal spasticity
  • Oral antispasmodics
  • Serial casting where contracture is developing
  • Selective dorsal rhizotomy in refractory cases

Neuromodulation

Assisting recovery of function

  • Transcranial magnetic stimulation (TMS) for motor recovery
  • Peripheral nerve stimulation
  • Constraint-induced movement therapy

Secondary prevention

Preventing the next event

  • Blood-pressure optimisation
  • Antiplatelet or anticoagulation as indicated
  • Lipid control, glycaemic control
  • Lifestyle: smoking cessation, exercise, weight management

The acute event is managed at the emergency department. Anyone who suspects a stroke should call for an ambulance immediately, not book a clinic appointment.
