What does migraine with aura mean?
Migraine is a chronically recurrent neurological disease in which the patient complains of throbbing, throbbing, and severe pain in one or both areas of the head. Sometimes severe pain is accompanied by nausea, vomiting, and hypersensitivity to sound or light.
Migraine with aura - Causes
Migraine with aura (also called classic migraine) is a recurring headache that strikes after or at the same time as sensory disturbances called aura.
These disturbances can include flashes of light, blind spots, and other vision changes or
tingling in your hand or face.
Treatments for migraine with aura and migraine without aura (also called common migraine) are usually the same. You can try to prevent migraine with aura with the same medications and self-care measures used to prevent migraine.
The exact cause of migraine is unknown, although both genetic and environmental factors play a role in the development of neurological disease.
It is quite possible that changes in the brain stem and its interaction with the trigeminal nerve are involved in the formation of chronically recurrent neurological disease, and the imbalance of brain chemicals is also noteworthy.
Risk factors include:
- Hormonal changes (in women);
- Excessive alcohol consumption;
- Stress, anxiety;
- Dazzling light or loud noise;
- Sleep problems;
- Physical strain;
- Weather change;
- Some medications and more.
There is evidence that the migraine aura is due to an electrical or chemical wave that moves across the brain. The part of the brain where the electrical or chemical wave spreads determines the type of symptoms you might experience. This electrical or chemical wave can occur in areas that process sensory signals, speech centers or centers that control movement.
A family history of migraine should be considered.
However, the diagnosis of migraine is much more common in women.
Symptoms
Migraine aura symptoms include temporary visual or other disturbances that usually strike before other migraine symptoms — such as intense head pain, nausea, and sensitivity to light and sound.
Migraine aura usually occurs within an hour before head pain begins and generally lasts less than 60 minutes. Sometimes migraine aura occurs without headache, especially in people age 50 and older.
Most people who have migraine with aura develop temporary visual signs and symptoms, which tend to start in the center of the field of vision and spread outward.
These might include:
- Blind spots (scotomas), which are sometimes outlined by simple geometric designs
- Zigzag lines that gradually float across your field of vision
- Changes in vision or vision loss
- Flashes of light
Other disturbances
- Numbness, typically felt as tingling in one hand or on one side of your face that may spread slowly along a limb
- Speech or language difficulty
- Muscle weakness
