I would be courteous to know how Occipital Neuralgia ties into this, if it does! I have ATN, ON, and cervicogenic headaches. They all started at pretty much the same time.
Aware this is not helping, but as I noted above I find no convincing evidence that referred pain of cranial nerves to headache is possible. If it's a headache it should involve the meniscal nociceptors, the only pain receptors in the brain. Similarly, ATN is not a proper diagnosis, because it involves areas that are not related to the trigeminal nerve, and if you do research on the condition, there is basically nothing other than some case diagnosis. ATN seems to be a term used a hundred years ago and never properly defined. So for once, doctors not only cannot cure a disease but not even diagnose it. I can see that iron deposits would cause facial pain, inflaming nerves. Typically iron deposits form from trauma including surgery. Also often when a proper diagnosis is lacking (the industry is very good at diagnosing things), it could mean the cause is a side effect of a drug. Such as, for a related syndrome, burning mouth: "Many medications are intimately related with burning mouth; among which are found antihistamines, neuroleptics, some antihypertensives, antiarrhythmics and benzodiazepines. Antihypertensives are among the most frequently implicated medicines, principally those that act on the renin-angiotensin system (13)."

Does that mean that issues in C1-C3 could refer back into the areas of the face innervated by the trigeminal nerve too? Or can it only go one way up to the head?
Ok I'm just flat out calling BS on this sentence in the slide: "thus, any noci stimulus ... can refer into the head and cause a headache" First of all the multiple nuclei are simply areas of 'axon extensions'. Extending signals from one neuron to the next. Exactly like car connectors bundling and passing through wires. And like nuclei, you can only put so many wires in a connector. For all I know up to now there is no processing happening in the nuclei other than passing along the signals. The trigeminal tract simply collects these nerve fibers on a common path. They are still separate neurons, each one will still trace back to the correct origin. I can distinguish pain on the scalp face and neck from a headache, I assume it's because the nociceptors in the meninges is what causes a headache. I suppose there is no nerve associated with meningual nociceptors, since they don't need to travel to the brain they are already where they need to be.

Thanks!
Thank you!
Thank you so much this is such a good explanation of difficult structure in a such digestible way!
A sensational explanation
Mind blowing vdos keep uploading more vdos on CNS
Really nice explanation! Thank you.
