Cortical Spreading Depression is thought to be one of the leading causes or triggers of migraine headaches. Migraine headaches are categorized as both a vascular condition as they are a neurological condition. They affect both systems in the body and cause discomfort to both. CSD or Cortical Spreading Depression occurs when neural activity is started and then slowly depressed or dampened over time that the depression can go from the back of the head to the front in a matter of thirty minutes. When this occurs, inflammatory go-betweens, as they are called, are released which lead to the irritation and inflammation of many cranial nerve roots such as the trigeminal nerve. This will cause the immense pain associated with migraines and make you think twice about doing anything as you can be incapacitated for several days.
Triggers
Just like Cortical Spreading Depression, there are many other migraine triggers which catalyze the migraine process. They are usually divided up into two groups: environmental triggers and physiological triggers. Here are some of the environmental triggers: weather changes, barometric changes, humidity, dry air, smells like body odor or perfume, cigarette smoke, bright lights (photophobia), loud noises (phonophobia) and even stress. The physiological triggers that one can encounter could be: certain foods like chocolate, caffeine, alcohol, hunger, emotional stress, fatigue, excessive sleeping and even neck tension. Triggers like these should be avoided. If you are triggered by bright light, don’t go to the beach. However, some triggers can’t be avoided. For example: if you triggered by body odor smells and you are a gym teacher or football player, you can’t just not show up to work trying to avoid these triggers and the onset of a migraine. So you must supplement your trigger-avoiding deficiencies with a choice migraine treatment option.
Aura Stage
This is the stage that you would experience the Cortical Spreading Depression and with only 15% or so of the migraine population going through this stage, chances are you might not ever experience this horrible stage. If you do however, you could have symptoms such as: blurred vision, zigzag vision, black spots in eyes, blindness in one eye temporarily, vertigo and even hallucinations.
