3. Sudden Vision Problems
Blurred, double, or sudden loss of vision in one or both eyes is a serious warning sign of a stroke.
Why It Happens
- A stroke can reduce blood flow to the optic nerve or the visual processing centers of the brain.
- This can lead to blurry vision, partial blindness, or trouble focusing.
When to Seek Help
- If vision suddenly becomes blurry, dark, or doubled.
- If you lose sight in one or both eyes temporarily.
- If you struggle to track moving objects.
4. Severe Headache with No Known Cause
A sudden, intense headache—often described as the worst headache of your life—can indicate a hemorrhagic stroke (caused by a brain bleed).
Why It Happens
- A ruptured blood vessel in the brain causes pressure to build up, leading to an explosive headache.
- This is more common in people with high blood pressure, aneurysms, or blood vessel disorders.
When to Seek Help
- If you experience a sudden, excruciating headache.
- If the headache comes with vomiting, dizziness, or neck stiffness.
- If it worsens within seconds or minutes.
5. Loss of Balance or Coordination
A person may suddenly feel dizzy, stumble, or struggle to walk—even if they were fine moments before.
Why It Happens
- A stroke can damage the brain areas responsible for balance and coordination.
- It can also cause vertigo (spinning sensation), making it hard to stand or walk.
When to Seek Help
- If you suddenly feel off-balance or unsteady.
- If you experience dizziness with vomiting or nausea.
- If you can’t walk in a straight line or stand without help.
