Sudden changes in vision are another early warning sign of a stroke. This can include blurred vision, double vision, or even the complete loss of vision in one or both eyes. These symptoms occur when the part of the brain responsible for processing visual information is affected by the reduced blood flow. Vision loss during a stroke is typically painless, but the sudden onset can be alarming. Any abrupt changes in vision, especially in conjunction with other stroke symptoms, should prompt immediate medical attention.

4. Severe Headache with No Known Cause

A sudden, severe headache can be a sign of a hemorrhagic stroke, which occurs when a blood vessel in the brain ruptures, causing bleeding. Unlike other types of headaches, the pain associated with a stroke is often described as the worst headache of one’s life and can be accompanied by vomiting, dizziness, or altered consciousness. This type of headache may develop rapidly and without any known cause, such as physical exertion or injury. While not every headache indicates a stroke, the sudden onset of an intense headache, especially with additional neurological symptoms, should never be ignored.

5. vertigo, unsteadiness, or trouble walking

A stroke can affect the brain’s ability to control movement, balance, and coordination. Individuals experiencing a stroke may suddenly feel dizzy or have difficulty walking, resulting in a loss of balance or coordination. They may appear unsteady on their feet, stumble, or even fall unexpectedly. In some cases, they may feel a spinning sensation (vertigo). These symptoms occur because the stroke affects the parts of the brain responsible for motor control and spatial awareness. If someone appears to be losing their balance for no apparent reason, it is important to consider the possibility of a stroke.
