Stroke: Diagnosis, Treatment, and Recovery Guide
A guide to recognizing stroke quickly, understanding imaging-based emergency treatment decisions, and planning individualized rehabilitation.
Contents
What is stroke and what are its types?
Stroke is a medical emergency caused by a sudden interruption of blood flow to part of the brain or by a ruptured blood vessel. In ischemic stroke a clot blocks an artery; in hemorrhagic stroke bleeding occurs within or around the brain. Symptoms cannot distinguish them and their treatments differ. Emergency imaging and specialist assessment are required before giving a medicine, including aspirin. Symptoms that disappear within minutes may still represent a transient ischemic attack and can warn of near-term stroke risk.
- Record when symptoms began or when the person was last known well.
- Do not give food, drink, or oral medicine because swallowing may be unsafe.
- Do not cancel emergency assessment when symptoms improve.
Waking with stroke symptoms
A person may go to sleep well and wake with facial droop, arm weakness, or speech or vision change. An unknown onset time does not mean treatment is impossible. At hospital, CT, CT angiography, perfusion imaging, or MRI may assess bleeding, vessel blockage, and tissue that might be saved. Some people qualify for reperfusion treatment based on imaging and other criteria; only the stroke team can make that decision.
Recognizing signs with FAST
Stroke signs usually begin suddenly. FAST prompts a quick check for facial asymmetry, weakness in one arm, and abnormal speech, followed by an immediate emergency call if any sign is present. Sudden loss of vision or double vision, severe loss of balance or coordination, numbness, and an unexplained severe headache may also be stroke signs.
| Letter | Check | Action |
|---|---|---|
| F — Face | Does one side droop when smiling? | Note the onset time. |
| A — Arm | Does one arm drift down when both are raised? | Stay with the person. |
| S — Speech | Is a simple sentence slurred or strange? | Do not wait if it resolves. |
| T — Time | Is any one sign present? | Call 112 immediately. |
Emergency diagnosis and treatment selection
The hospital team first excludes bleeding, then evaluates the vessel and brain tissue. Clot-dissolving medicine or catheter thrombectomy can benefit selected ischemic strokes. Eligibility depends on more than the clock: last-known-well time, imaging, site of occlusion, bleeding risk, medicines, and overall condition all matter. Do not use a fixed time window to rule yourself out. Earlier assessment preserves the greatest range of options.
Rehabilitation after stroke
Once medically stable, rehabilitation is planned around movement, balance, arm and hand use, speech, cognition, vision, swallowing, and daily activities. The team may include neurology, rehabilitation medicine, physiotherapy, occupational therapy, speech and language therapy, nursing, nutrition, and mental health professionals. Recovery rates vary. Gains are often fastest in the first months, but progress can continue later. Realistic measurable goals and a safe home program support participation and independence.
- Eating before a swallowing assessment may carry aspiration risk.
- Falls, shoulder pain, skin care, and caregiver strain belong in follow-up.
- New sudden symptoms during rehabilitation require renewed emergency assessment.
