A pounding, throbbing headache Bright zigzagging lines across your field of vision, light sensitivity, lingering fatigue, sleep disruption, Any of these symptoms could be caused by a migrane. While incapacitating headaches are one of the most common migraine symptoms, the term “headache” does not adequately describe the wide range of migraine symptoms. There are no two alike, and some do not even involve a headache.
So, exactly what is a migraine?
What happened in the mind to cause it?
To trace the anatomy of a migraine, we must start in the days and hours before the attack, when people frequently notice warning signs such as fatigue or mood changes, bursts of yawning, sleep disruption, nausea, light and sound sensitivity, or even increased thirst. These symptoms point to a specific area of the brain.
Hypothalamus
The hypothalamus normally controls the system behind these symptoms. Our bodies’ internal hormonal balances, circadian rhythms, and water regulation. It has wide connections throughout the brain, and is more active than usual in the days before a migraine. Another common warning sign is the migraine aura. which can appear as transient visual changes, tingling, or even difficulty speaking.These sensations are caused by a charge change across cell membranes. As a result, there are widespread changes in brain activity and blood flow throughout the brain.
We don’t know what causes this change in charge, but it can spread quickly across the brain’s surface, causing varying aura symptoms depending on the affected area.It fights back against the visual cortex.
For example
It may cause an image or blind spot to spread over the visual field.
Trigeminal nerve
The trigeminal nerve is important during the headache phase. Touch, temperature, and other sensations are normally transmitted from the skin to the majority of the face, a portion of the scalp, and some of the blood vessels and layers covering the cerebral cortex via the trigeminal nerve. The tregiminal nerve transmits pain signals once activated. This pain pathway becomes sensitised during a migraine, which lowers the threshold for causing pain. Coughing, bending over, or exposure to light and sound, which are normally painless, can become painful.
Migraines are as common as they are diverse, affecting up to 33% of women and 13% of men in their lifetime.Still, we don’t know much about them.As we can see, migraine is a neurological disorder that affects several parts of the brain.The nerves themselves, as well as the brainstem and cerebral hemispheres.But we don’t know what exactly causes each step.
Why do some people get migraines while others do not?
Why are more women affected than men?
Or why do people’s migraine patterns or sometimes shift over the lifetime of a person?
Some of these are thought to be caused by hormonal fluctuations.After menopause, when sex hormone fluctuations are reduced, some women notice a significant reduction in migraine frequency.
Meanwhile, these fluctuations increase just before menopause, and some women experience worsening or new headaches.Migraine sufferers are more likely to develop depression, panic disorders, sleep disorders, and strokes, among other illnesses.The connection between these diseases is most likely complicated.Perhaps due to the effect of migraine on those diseases, or vice versa, or to their shared genetic basis.With a few exceptions, genetics almost certainly plays a role, but there is no single gene that causes migraines.Certain genes regulate how easily our brain neurons are stimulated by external stimuli and how easily they transmit painful signals.
It is possible that neurons in migraine sufferers’ brains are more easily triggered by environmental stimuli and are less likely to block painful signals. While there is no simple explanation for what happens in our brains when we have this complex disorder.A migraine is much more than a headache, this is quite sure.
