Does anyone know of specific research in blood pressure spikes with regards CH or any Primary HA.

Also what is current technology status on Real Time Continuous Blood Pressure Monitoring.

Reason, I am interested to research possible links of (commonality of) "Tringgers" in creating a ramp in blood pressure.

And also any research on Hypertension remedies that not only reduce BP but level out spikes.

It appears that many of the things that give relief to CH also have a property of reducing BP; Drugs (incl vit D), Oxygen (reducing blood flow), nerve stimulation, relaxation/meditation etc

I am convinced the relationship of internal BP (general and cranial) and atmospheric has an influence, so it may not be an internal trigger; food, drug,alcohol, anxiety/mood change etc but also if there is a rapid enough gradient change in lowering of atmospheric pressure (AP) then the resulting ratio between BP/AP would mimic an increase in BP.

I am particularly interested in what this gradient / ramp (increase in BP / Time) might be (if it exists as a function of CH); so relative BP (BP/AP) increase over "x" time is trigger but over "y" time not?

And it is specifically the ramp that I am interested in; in the population of normally; low, normal and high BP's not just hypertensive individuals.

Any pointers to existing research would be much appreciated.

"Andrew Booker, 52, had his blood pressure checked by his GP every six months due to a family history of strokes. The readings, he was assured, were fine and he was given  no medication.
But taking his blood pressure at home with a digital monitor revealed occasional high peaks of 190/130.
‘They coincided with times I got splitting headaches and felt hot,’ says Andrew, a safety administrator from Oxford. "

In just a day the research I've seen is showing BP spikes cause more than just headaches.

I wouldn't mind betting every CH episode is preceded by BP spikes (not run of the mill but out of the ordinary ones)

Boyles Law (or is it Charles'?) would explain why the differential temp / atmos pressure at different times in the season would have an effect on the internal going ons.
Take a balloon and take it from a high ambient pressure and put it in a lower pressure, it will grow. Take an aneurysm and wait for the barometer to drop and it will grow. If the aneurysm is touching a nerve the pressure will increase.
A BP spike (if you have an aneurysm is not good, it could pop). The brain doesn't know whats pressing on a nerve; aneurysm bone, muscle, facet, ligament. The brain cannot tell but if it has an evolved instinct to shut the body down when it senses an aneurysm is about to pop it might create a CH or Fit or unconsciousness.
It might not but it would be interesting if a trial was done to check the BP of sufferers prior to a CH attack. Once the first attack hits anxiety can take over and create the conditions for further attacks.

ps the evidence I'm seeing suggests that D3 does indeed flatten the BP wave. Funny that!

Blood Pressure Spikes Cause Primary Headaches; deductive or abductive reasoning?

Hi there,

Some 3/4 years ago, while in hospital for tests ( yet more tests) I was on a 24 hour BP monitor. I was being hit hard every couple of hours at the time and sucking oxygen like my life depended on it.

The BP result came back with no change whatsoever during the entire period. I have to say the Doctors were surprised.

My BP, which I check regularly myself and is "officially" checked every 4 weeks, as I donate Platelets, is always 120/80.

Maybe I'm just lucky in this regard, but a CH hit doesn't seem to make any difference to my BP.

Just a comment, for what it's worth.

Keep well everyone.

Peter.

ps after the first hit anxiety will kick in to create all the other hits until the brain realises its not dead yet, panic over!

Hence success of placebos (increased effectiveness over norm in primary headache) and CBT and relaxation therapies etc.

If the brain stops thinking a stroke is about to hit then it starts to calm down. Until the next spike.

In the 40+ years that I've been reading about Cluster I don't recall any causal linkage with BP.

A short term elevation as a part of a stress reaction, either to an attack or in anticipation of an attack, is consistent to the literature.

I think a simple (cheap) trial to establish if excessive BP fluctuations precede a CH would be to investigate the known preventative medications and see if there is a common attribute of levelling out the BP cycle.

It is known that Calcium Channel Blockers (CCB's)(e.g. Verapamil) do. If there is a common effect then a not unreasonable conclusion would be a pre-CH spike/trough in BP is a possible/probable trigger.
(But other co-effects would have to be analysed alongside)

Interesting trial by Yaprak Secil et al "Blood Pressure Changes in Patients Before, During and After Migraine Attacks"

Although other literature confirms the association to be controversial

It is known many triggers of CH create spikes in BP, it is known CCB's can level those spikes at the same time as acting as a preventative, a conclusion is that they are related. Atmospheric pressure also has an influence so if spikes (maybe troughs) are a causal trigger then their effects could be subtle but devastating.

The "remarkable" aspect is 115 obserations on hypertension in non hypertensive patients. But yes a proper trial needs to be done.

Coffee, chocolate, alcohol and sex cause spikes in BP (amongst other things) they also trigger Primary headaches.

"who will fund such a study"

If there's no money in it, the pharmas won't but there is no need for further trials;

The raw data exists, someone might want to pick it up for a phD thesis.

Things that cause BP spikes cause Primary HA's (incl CH). Things that stop spikes stop Primary HA's (incl CH).

Now where's me dosh? (or failing that my phD)
