A stroke can happen suddenly, without any warning – and when it does, every second counts. Many lives could be saved if more people knew the signs.
Weakness in an arm or leg

If someone suddenly can’t lift one arm or leg, or if the limb drifts downward when raised, it may be a sign of stroke. Ask the person to hold both arms up for 10 seconds – if one drops, call emergency services immediately.
Slurred or incoherent speech

Sudden changes in speech, such as slurring, confusion, or using the wrong words, are classic stroke indicators. Ask the person to repeat a simple sentence like “The sky is blue.” If they struggle, don’t wait – call for help.
Uneven smile

A lopsided smile, where only one side of the mouth moves, is a visible and serious warning sign. If facial symmetry is affected when smiling, it’s time to act quickly and call emergency services.

Sudden dizziness or loss of balance

Feeling dizzy, losing coordination, or struggling to stay balanced out of nowhere can point to a stroke – even if it seems minor at first. Never ignore these symptoms.
Severe headache with no clear cause

A sudden, intense headache that feels unlike any the person has had before should never be brushed off. If it appears with other symptoms like nausea, blurred vision, or confusion, seek emergency care immediately.
Vision problems

Stroke can impair vision in one or both eyes. Symptoms include blurred sight, double vision, or sudden loss of vision. These signs are often overlooked but are extremely serious.
Confusion or trouble understanding

Unusual confusion, difficulty understanding speech, or sudden problems finding words can be your brain’s distress signal. Immediate action is crucial.

Numbness or paralysis

Numbness or paralysis – often on one side of the body – is a classic stroke symptom. The person may lose the ability to feel or move one arm, leg, or side of their face.
Difficulty swallowing

Sudden trouble swallowing or choking on food or drink can indicate a stroke, especially when paired with other symptoms like facial weakness or slurred speech.
Time is critical: 4.5 hours

While not a physical symptom, this point is vital. Stroke treatment is most effective within 4.5 hours of symptom onset. Getting to the hospital fast can make the difference between full recovery and permanent damage.
