A stroke rarely comes completely without warning. In many cases, the body sends out urgent signals minutes before a major stroke

occurs, sometimes as little as 10–15 minutes in advance. Recognizing these signs and acting immediately can be the difference between life

and death, or between full recovery and permanent disability.

A stroke happens when blood flow to the brain is interrupted - either by a clot (ischemic stroke) or a ruptured blood vessel (hemorrhagic

stroke). Brain cells begin to die within minutes without oxygen. That’s why time is critical. The sooner medical care begins, the more brain

tissue can be saved.

Below are four clear warning signs that may appear shortly before a stroke. If even one occurs, call emergency services immediately or

alert someone nearby to get help right away.

1. Sudden Weakness or Numbness on One Side of the Body

One of the most common and alarming early signs of stroke is sudden weakness, numbness, or loss of control, typically affecting one side

of the body.

What it may look like:

• A drooping face on one side

• Inability to lift one arm or leg

• Tingling, heaviness, or complete numbness in the face, arm, or leg

• Sudden clumsiness or loss of coordination

This happens because the stroke disrupts blood flow to the part of the brain that controls movement and sensation. The effects are often

rapid and unmistakable.

Do not wait to see if it passes. Even if symptoms improve after a few minutes, emergency care is still essential.

2. Sudden Difficulty Speaking or Understanding Words

Another major warning sign involves speech and comprehension. The brain areas responsible for language are highly sensitive to oxygen

loss.

Possible signs include:

• Slurred or garbled speech

• Difficulty forming words

• Trouble understanding what others are saying

• Confusion or inability to respond appropriately

A person may know what they want to say but find that the words won’t come out correctly—or they may seem confused by simple

sentences.

If someone suddenly cannot speak clearly or understand you, assume it is a stroke until proven otherwise.

3. Sudden Vision Problems or Severe Dizziness

Vision and balance changes can occur just before or during a stroke and are often overlooked.

Watch for:

• Sudden blurred or double vision

• Loss of vision in one or both eyes

• Severe dizziness or vertigo

• Trouble walking or maintaining balance

These symptoms can appear abruptly and may be accompanied by nausea or a feeling that the room is spinning. They indicate disruption in

areas of the brain responsible for vision and coordination.

4. Sudden, Severe Headache With No Clear Cause

A sudden, intense headache, especially one described as “the worst headache of my life,” can be a critical warning sign—particularly of a

hemorrhagic stroke.

This headache may:

• Come on instantly

• Feel unusually intense or explosive

• Be accompanied by nausea, vomiting, or loss of consciousness

Unlike typical headaches or migraines, this pain often feels different and alarming. Never ignore a sudden, severe headache, especially if it

appears alongside other neurological symptoms.

Why Immediate Action Matters

Stroke treatment is extremely time-sensitive. Certain life-saving treatments are only effective if given within a narrow window—sometimes

within 3 to 4.5 hours, and in some cases much sooner.

Every minute a stroke goes untreated:

• Nearly 2 million brain cells die

• The risk of permanent disability increases

• The chance of survival decreases

Calling for help immediately can:

• Save brain function

• Reduce long-term disability

• Improve recovery outcomes dramatically

What to Do Immediately

If you or someone near you shows any of these signs:

• Call emergency services right away

• Do not drive yourself if symptoms are severe

• Note the time symptoms started

• Keep the person calm and still

Do not wait to call family later. Call for medical help first.

Final Message

The body often gives a brief but critical warning before a stroke. Sudden weakness, speech problems, vision changes, or a severe headache

are emergency signals, not inconveniences.

If these signs appear - even for a few minutes - act immediately. Reaching out for help in time can save a life, preserve independence, and

protect the brain from irreversible damage.

When it comes to stroke, every second counts.
