Migraine with aura or without aura. Unilateral throbbing, exertional vomiting, photophobia, phonophobia, go for migraine. A variant called ophthalmoplegic migraine will give you headaches and third nerve palsy, unilaterally. How do you know this is not due to diabetes? The onset is before the age of 20 in ophthalmoplegic migraine. That’s an important clue. So if a 40-year-old comes to you with third nerve palsy and a lot of headaches, think vascular, think diabetes. Persons before 20, even if the pupil doesn’t react, this probably comes first, ophthalmoplegic migraine. Look for family history. Cialis jelly strawberry, banana.
Childhood migraine may give headaches and vomiting, but it does one other unique thing. It gives you episodic confusion. Something like non-convulsive status epilepticus, or childhood migraine may be manifest by episodic confusion only, without headaches. Cyclical vomiting in small children is considered a variant of migraine. Status migrainosus is migraine lasting more than three days. The treatment is not working. The treatment for that is steroids, Decadron or DHE sometimes. Tension-type headaches could be episodic, two or three days a week, or it could be every day of the week. Bilateral, lacks pulsatile quality. This is the International Headache Society Criteria. Non-exertional, no vomiting, no photophobia, no phonophobia.
There is a physiological phenomenon called spreading depression. If you put potassium chloride on the brain surface, the neurons get suppressed. They don’t work for a little bit. In experimental situations, this kind of depression spreads from the central spot more anteriorally and more peripherally. Now they are vaso-physiologically measuring this kind of neuronal depression with magneto encephalogram and a whole bunch of other things, PET scan and all kinds of stuff. What seems to happen is that when you have aura the cerebral cells do exactly what would happen during spreading depression. There is a slow march of suppression of neuronal activity. It spreads. Now this has been shown to correlate fairly well with the aura, so the aura now is considered to be primary neuronal depression. So when the neuron misbehaves like that, the blood vessels change but the blood vessel changes seem to be secondary. So there’s one piece of evidence. Aura is not due to vasoconstriction, but it seems very likely due to the spreading depression phenomenon. Canadian generic viagra online.
