A visual migraine, also known as a migraine with aura, is not a stroke. While both conditions can cause similar visual disturbances, they are caused by different underlying mechanisms.
A visual migraine is a type of migraine headache that is preceded or accompanied by visual disturbances, referred to as an aura. These auras can include flashing lights, zigzag lines, blind spots, or blurred vision. They usually last for about 20 minutes to an hour and gradually disappear, followed by the onset of a migraine headache.
On the other hand, a stroke occurs when the blood supply to the brain is interrupted, leading to brain damage. Strokes can cause various symptoms, including sudden weakness or numbness on one side of the body, difficulty speaking, severe headaches, and changes in vision. Unlike visual migraines, strokes are a medical emergency that requires immediate medical attention, as they can have long-term effects or be life-threatening.
While visual migraines and strokes have some similar symptoms, they have distinct causes and mechanisms. Visual migraines are thought to be caused by abnormal electrical activity in the brain, specifically in the visual cortex, leading to the visual disturbances. On the other hand, strokes can be caused by a blockage in a blood vessel (ischemic stroke) or the rupture of a blood vessel (hemorrhagic stroke), preventing oxygen and nutrients from reaching the brain cells.
In summary, a visual migraine is not a stroke. While both conditions can cause visual disturbances, they have different underlying causes. It is important to differentiate between the two, as strokes require immediate medical attention, while visual migraines can be managed with lifestyle changes and medication. If you experience any sudden or severe changes in vision, it is always advisable to seek medical advice to rule out any serious conditions like a stroke.
How do you know if your migraine is a stroke?
Generally, migraine tends to come on gradually and feature ‘positive’ symptoms (this means added sensations) such as flashes in vision or tingling. Stroke or a TIA tend to come on suddenly and feature ‘negative’ symptoms (loss of sensation) such as loss of vision in one eye or loss of feeling in one of your hands.
How do you stop a visual migraine?
