6 Warning Signs of an Impending Stroke

3. Sudden Vision Problems

Changes in vision may occur in one or both eyes during an impending stroke.

Symptoms include:

• Blurred or double vision
• Loss of vision in one eye
• Difficulty seeing to one side

Why it happens:

• The stroke affects the occipital lobe or optic pathways responsible for visual processing.

Action:

• Do not ignore sudden vision changes, especially when combined with other stroke symptoms. Seek immediate medical attention.

4. Severe Headache

A sudden, intense headache may indicate a stroke, particularly hemorrhagic strokes caused by bleeding in the brain.

Characteristics:

• “Worst headache of my life” sensation
• Rapid onset and increasing intensity
• May be accompanied by nausea or vomiting

Why it happens:

• Blood leaking into brain tissue increases intracranial pressure and irritates nerves.

Action:

• Emergency care is crucial. Do not attempt to drive yourself; call an ambulance.

5. Loss of Balance or Coordination

Sudden dizziness, loss of balance, or difficulty walking can signal stroke, especially when affecting the cerebellum or brainstem.

Symptoms include:

• Trouble maintaining posture
• Unsteady gait
• Dropping objects due to lack of coordination

Why it happens:

• Blood flow disruption in areas controlling movement and coordination leads to sudden instability.

Action:

• Ensure the person does not fall and call emergency services immediately. Early intervention can prevent permanent disability.

6. Sudden Trouble Swallowing

Difficulty swallowing, also known as dysphagia, may appear before or during a stroke.

Symptoms include:

• Choking or coughing while eating or drinking
• Sensation of food sticking in the throat
• Difficulty controlling saliva

Why it happens:

• Areas of the brain that regulate the swallowing muscles are affected by stroke.

Action:

• Seek immediate medical attention. If left untreated, dysphagia raises the risk of aspiration and pneumonia.
