The recent research has shown convincingly that migraine and headache is underpinned by sensitisation of the brainstem or central sensitisation.
One of the potential sources of senstisation of the brainstem is abnormal information from a disorders of structures within the head, structures which are supplied by the trigeminal nerve. It is then interesting to find that headache persists after blocking information carried by the trigeminal nerve. This clearly demonstrates that headache or migraine can come from other sources, for example neck disorders, and that the triptans act on structures other than in the head to ease headache or migraine … a sensitised brainstem … sensitised from another source … perhaps a neck disorder?
This can be easily confirmed by a skilled examination of the upper neck structures.

Interesting to note that a recent study when reviewing migraine-associated characteristics including aura, allodynia-associated (excessive tenderness to touch) symptoms, photophobia (sensitivity to light), phonophobia (sensitivity to noise), and nausea were similar for both menstrual migraine and non menstrual migraine sufferers.
Furthermore the triptans were equally effective for both menstrual related migraine and non menstrual migraine patients.
I have also mentioned before, research which demonstrates that the triptans desensitise the brainstem – a case for sensitised brainstems in menstrual migraine sufferers.

As I have mentioned previously, recent and substantial research demonstrates that the different types of headache and migraine develop from a common, shared disorder, and that this disorder is sensitisation of the brainstem.
Auras, which initially were thought to only accompany migraine and menstrual migraine, have now been reported in Cluster Headache and Hemicrania Continua, and provides further evidence that the various forms of headache and migraine are likely to originate from common disorder.

It is generally agreed and it has been demonstrated that the brainstems in migraineurs and tension headache sufferers are sensitised.
The brainstem is influenced by 4 systems:
information from structures inside the head – head scans which fortunately in over 95% of headache and migraine sufferers the scans are clear, will eliminate this factor
the diffuse noxious inhibitory control system – this is poorly understood, but it is the mechanism which acts when you hit your thumb with a hammer and your headache seems less painful – hardly an attractive treatment option!
the serotonin system – serotonin desensitises the brainstem – if there is not enough then the brainstem becomes sensitised – so it makes sense to optimise your production of serotonin – diet, exercise, sunlight and perhaps a L-tryptophan supplement (after checking with your doctor)
information from the neck – get your neck checked. Many of us have a neck disorder, but is it relevant? This can be determined by, when examining the neck, temporarily reproducing familiar head pain which lessens as the technique is sustained. In my 21000 hours of experience this occurs in over 90% of headache and migraine conditions. My approach as a diagnostic tool is unparalleled in the manual therapy area and is in accordance with the views of traditional medicine.
Why does it have to be complicated?
The last two systems are within your control – you can take steps to address these.

“ … little does it concern the patient that there is an underlying cause … if the practitioner is unable to relieve his pain.” (Persian Avicienna – Critchley 1967)
This statement was made 2000 years ago and remains true today – patients are seeking treatment, but since the cause of migraine remains unclear, treatment is provided on a less than solid scientific foundation, on a ‘we’ll try this and see what affect it has’ basis.
However what is becoming increasingly clear (except to those who continue to support the notion that headache and migraine are separate entities) is that headache and migraine arise from the same (sensitised brainstem) disorder – the evidence is there – this is the underlying cause. Not only can we confirm relevant neck disorders as the source but we can offer a way of addressing it, based not on guesswork but on sound scientific evidence.

Q. What do diagnosing headache and migraine and a dog’s breakfast have in common?
A. It’s all over the place!
This is expressed in a recent article by Sun-Edelstein et al 2008. Since the diagnostic classification was published, there have been many attempts to confirm or otherwise the accuracy of the criteria. Because of the multiple revisions since, there exists a great deal of controversy and significant confusion, with headache specialists unsure as to which criteria to use.
Many patients after having received an initial diagnosis, are given a second diagnosis, with some requiring 3-4 diagnoses!
This is clearly unsatisfactory …. and is the result of trying to prove an untruth. The various types of headache and migraine are not separate entities, they are on a continuum, developing from a common disorder.

‘Benign’ (or harmless) Exertional Headache is defined as headache caused by exertion such as coughing, sneezing, bending, heavy lifting, running (how is this different to headache triggered by exercise?) or when straining at stool.
It is important that if your headache history is less than 3 months and is triggered or aggravated by these activities that you consult you doctor.
These activities create similar effects on the body as do the Valsalva manoeuvers.
Recent research1 found a wide range of symptoms in Exertional Headache, some with migrainous symptoms, and the authors suggested that the ‘triptans’ might be useful. As usual there is a lot of discussion as to the actual mechanism of Exertional Headache and indeed Exercise Induced Headache, but the causes remain unknown – why?
The Valsalva manoeuver is used (and has been for years) to identify problems or injury in the nerves of the cervical spine. Upon the exertion of pressure, pain may be felt, and may indicate increased pressure on the C2-3 intervertebral disc or other part of a cervicogenic (neck) disorder.
Clearly increased headache or headache or migraine triggered by exertion or exercise is likely to be caused by a neck disorder.

Avoiding chocolate to prevent migraine is not necessary – it isn’t about the chocolate!
The thought of living without chocolate is unbearable but I know that for many of you, the experience is not worth it!
However, many of my patients are now eating chocolate, in fact this is what I ask them to do after 3-4 treatments – and you can imagine their (and mine!) delight when they do so without headache or migraine.
But why is it that I can eat chocolate without headache – I’m sure that chocolate has the same effect on me as it does on someone else who ends up with a headache. For example phenylethylamine (PEA) is a chemical in chocolate that causes blood vessels to expand and contract – this probably happens for everyone, but not everyone gets headache or migraine. Some might say that the chocolate sensitises their system, whilst some authorities suggest that their system is already sensitised before the chocolate came along.
I suspect that just as in migraine and tension headache sufferers, the brainstems of those whose headache or migraines are triggered by chocolate, are already sensitised. The normal response of the blood vessels to PEA is to expand, but the pain interpreting centres in the brain understands this (normal) increased activity to be much more than what it is and pain results.
What’s causing the sensitisation? It is easy to confirm a neck disorder because temporary reproduction and lessening of head pain occurs when examining the joints of the upper neck – it is important to confirm the source of sensitisation …
… then you can enjoy the benefits of eating (good quality and dark) chocolate:
a natural mood enhancer
a stress reliever
a memory enhancer
improves your levels of serotonin (which will desensitise your brainstem).

I mentioned recently that blocking the greater occipital nerve and eliminating head pain is key sign of cervicogenic or neck headache and that this has been demonstrated repeatedly in migraine sufferers.
This procedure (injecting nerves) however is not necessary to diagnose cervicogenic headache which is just as well because after all it is invasive, not readily available and relatively expensive.
The ability to temporarily reproduce familiar head pain when examining joints of the upper neck is recognised by traditional medicine as one of the most important indicators of cervicogenic headache (actually, I have to disagree with this, reproduction alone is not enough – there needs to be lessening of the head pain as the examination technique is sustained – more of that later).
It is irresponsible to recommend treatment of the neck for headache or migraine when it is not the cause and therefore it is crucial that reproduction and lessening of head pain occurs during the examination.
The examination approach I have developed on the basis of 21000 hours experience is unparalleled – in recent research familiar head pain was reproduced in 100% of tension headache sufferers and 94% of migraineurs …. now I could be cynical and say that 100% had tension headache and cervicogenic headache and 94% migraine sufferers had cervicogenic headache as well.

There are numerous case studies which have shown that injecting local anesthetic around the greater occipital nerve the pain of migraine is eased. This is also a key finding in cervicogenic headache and confirms the diagnosis of cervicogenic headache. So why is it that, in this situation, almost invariably the interpretation is that the sufferer has two types of headache that is:
cervicogenic headache,
and
migraine
I am always bemused by this, why can’t it be that the ‘migraine’ and cervicogenic are the same headache.
Why is it that the answer I often get is “… well we don’t know where migraine comes from but it can’t come from the neck.” Clearly this is a really unhelpful comment. Why is it that I need to demonstrate that the neck can be the source of sensitisation in migraine sufferers (my claim is based on over 21000 hours experience with headache and migraine sufferers)? Perhaps I should request from those who disagree to demonstrate that migraine cannot develop from a neck disorder ….
