Danish Headache Center · Annual Report 2008 1
Preface
This annual report provides an overview of the clinical and research activities that took
place at The Danish Headache Center in 2008.
The clinical activities have been maintained at a very high level both in terms of
productivity and quality thanks to our highly committed staff members. Most important,
the feedback from the patients continues to be very positive.
In order to continuously improve the quality of the clinical work several new treatments
have been introduced in 2008. A new treatment programme for patients with
posttraumatic headache has been introduced as well as a new treatment programme
using functional electrical stimulation for patients with headache due to increased
contraction of jaw muscles. A large project comparing two different treatments for patients
with medication-overuse headache has been started. Furthermore, we are planning to
introduce new treatment strategies for severely affected cluster headache patients.
The research at The Danish Headache Center and the affiliated Glostrup Research Park
continues to be very active with a high number of publications and a large impact factor.
In 2008 no less than 6 Ph.D-theses were successfully defended by our young
researchers. Congratulations.
The European Headache Summer School was held in Baku, Azerbaijan in May. It was
arranged by Messoud Ashina and Rigmor Jensen in collaboration with Professor Rena
Shiraliyeva, Dept. of Neurology, Republican Clinical Hospital, Baku, Azerbaijan and was
a great success.

The in-patient headache service
Six beds at the Department of Neurology N38 are allocated to the in-patient programme.
The majority of patients are suffering from medication-overuse and are admitted for
detoxification. In addition, patients suffering from other types of headache can be
admitted for observation, certain specialized diagnostic procedures or treatment that
requires hospitalization. The medication-overuse patients are all primarily seen on an out-
patient basis in the Centre and then admitted for a fixed in-patient period of 14 days and
follow a structured regime. After discharge they are closely followed as out-patients in
DHC for at least one year.

Human migraine models

Dorte Phillip and Jes Olesen.
Background
Fast tracking of new drugs for migraine have faced the major challenge of poorly-
predictive preclinical models. Indeed, novel, migraine-specific preventive drugs have not
been developed in decades. Furthermore, the acute therapy armamentarium remains
suboptimal, with no new chemical entities since the triptans. On the other hand, human
experimental studies are surfacing as a powerful tool in targeted migraine therapy. To this
end, human studies have identified three novel targets: inhibitors of cortical spreading
depression, antagonists of calcitonin gene-related receptors, and chemicals that prevent
the production of nitric oxide. Two of these novel mechanisms are in phase 3 clinical
development and one is in phase 2. These encouraging observations, which are based
on 20 years of research in human models, have led us to develop a research paradigm
for the identification of novel migraine drug targets, which combines human provocation
studies and preclinical models.
Current projects
• GTN and CGRP models of migraine in patients with genetically explained
hemiplegic migraine and migraine with aura
• Carbachol and PACAP models of migraine in patients with migraine without aura
• Role of prostaglandins in migraine pathophysiology: PGI2, PGE2 and PGD2
models of headache
• Activation of trigeminal pain pathways during different sequences of CGRP
induced migraine attack: fMRI study

Tension-type headache
Members
Lars Bendtsen, Line Buchgreitz, Kim Lindelof, Peter Schmidt-Hansen, Rigmor Jensen.
Background
Increased understanding of the relative importance of peripheral factors (mainly
muscular) and central factors (mainly central pain processing) in the pathophysiology of
tension-type headache are crucial for the development of more effective treatment
options for this disorder. Experimental models studying muscular factors, e.g. muscle
pain sensitivity, and central factors, e.g. degree of wind-up, and the interaction between
these factors are needed to explore the cause/effect relationship between the various
peripheral and central abnormalities reported in tension-type headache. Previous studies
from our group have, e.g., demonstrated abnormal tenderness and pain perception
indicating central sensitization.
Current projects
Investigations of muscular pain sensitivity, processing, and modulation of peripheral
nociceptive input in the central nervous system.

Epidemiology
Members
Line Buchgreitz, Rigmor Jensen.
Background
Epidemiology is the study of the distribution and determinants of health-related states or
events in specified populations. The Glostrup County population study from 1989 was the
first prevalence study of specific headache entities in a representative general population,
based on a structured interview and examination by a physician. This study demonstrated
the huge impact headache has on individuals and society. A follow-up study showed an
increase in frequency and health care utilisation and thereby indicated a higher impact of
headache in 2001 that in 1989. Risk factors for migraine were young age, female gender,
familial disposition, no vocational education, high work load and frequent tension-type
headache. For tension-type headache risk factors were young age, female gender, poor
Danish Headache Center · Annual Report 2008 11
self-rated health, inability to relax after work, and sleeping fewer hours per night. In
general migraine and tension-type headache had a favourable prognosis with increasing
age and only a minority of subjects had increased headache frequency. Prognostic
factors were identified.
Current projects
Supplementary dataanalysis of the large follow-up study is ongoing with specific focus on
chronification, clinical headache characteristics and socioeconomic impact. A large
clinical study of patients treated at the Danish Headache Center has already been
conducted with main focus on medication overuse headache. It has been demonstrated
that detoxification have a very positive outcome, especially in migraineurs and that these
patients becomes reactive to migraine prophylactics again. Several new projects focusing
on specific treatment results and neurobiological mechanisms underlying medication
overuse headache are ongoing.
Genetics and environment
Members
Anne Hauge, Han Le, Jes Olesen.
Background
Family studies and twin studies show that the risk of migraine is 50% inheritance and
50% environment. The identification of genes involved in migraine may give clues to
underlying pathophysiological mechanisms. It is equally important to identify the
environmental factors, which so far are largely unknown.
Current projects
One aim of our studies is to identify the genes involved in migraine with aura, familial
hemiplegic migraine, and migraine without aura. To date we have collected blood from
more than 1400 migraine patients and the molecular genetic analyses have been
initiated. In twin studies we try to identify the most important environmental risk factors for
migraine.
Intracellular transduction mechanisms in migraine
Members
Christina Kruuse, Carina Jørgensen, Lars Schack Kruse, Julie Carøe Kristensen.
Background
Studies in humans help to explore possible migraine and headache provoking factors, in
12 Danish Headache Center · Annual Report 2008
order to understand migraine pathophysiology. It is known that pain signalling in humans
involve second messenger signalling through both types of second messengers; cyclic
adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP).
However, the function and interaction of these signalling pathways and the cellular
location in either neuronal or vascular cells is not fully understood. The aim is thus to
localize and investigate function of tissue and cells assumed relevant in initiation of the
pain process in order to investigate potential treatment targets. In collaboration with
Department of Clinical Biochemistry Glostrup, Department of Neuroscience and
Pharmacology and Functional Imaging Unit and Dept Clinical Physiology and Nuclear
medicine we describe the presence of some of the intracellular signaling molecules,
involved in the pain process, the effects of modulating the signalling cascade in pain and
regulation of cerebral artery diameter in cell and tissue based systems as well as in
humans.
Current projects
We are currently looking at the distribution and function of phosphodiseterases (PDE),
which are responsible for controlling the cAMP and cGMP levels in the cells. In particular
how they may relate to the pain sensing structures in the brain and play a part in the
induction and possible maintenance of headache and migraine.
Pharmacological and molecular studies of the cranial circulation
Members
Inger Jansen Olesen, Saurabh Gupta, Louise Juhl Boni, Kenneth Beri Ploug, Helle Wulf,
Michael Baun, Maja Myren, Dipak Vasantrao Amrutkar, Deepak Kumar Bhatt, Roshni
Ramachandran, Jes Olesen.
Background
We have during the last 20 years studied the pharmacology of isolated cranial blood
vessels from animals and humans in vitro. This work has led to several publications on
the characterization of cerebrovascular receptors for 5-hydroxytryptamine and the
sensory neuropeptides calcitonin gene-related peptide and substance P. During the last
5-8 years we have introduced new techniques, giving us the ability to study the
expression of mRNA and proteins for specific receptors in migraine relevant tissue. In
addition, we have established the genuine closed cranial window technique. This method
allows us to perform in vivo measurements of the effect of a drug on pial and dural
arteries when administered intravenously. We have further developed the method such it
is possible to give drugs by intracarotid infusion.
Danish Headache Center · Annual Report 2008 13
Current projects
The episodic nature of migraine attacks suggests that ion channels are involved in its
pathophysiology. This is confirmed by finding the mutation in patients suffering from
familial hemiplegic migraine within three different ion channel genes identified to date.
Potassium channels have an important role in the regulation of vascular tone and an
opener of ATP sensitive potassium (K(ATP)) channels has in clinical trials been found to
induce headache. An other channel we find might be important in migraine
pathophysiology are the large conductance calcium activated potassium (BK(Ca))
channel. Furthermore, the receptors for vasoactive peptides and prostanoids such as
vasoactive intestinal peptide (VIP) and pituitaty adenylyl cyclase activating peptide
(PACAP), calcitonin gene-related peptide (CGRP), prostaglandin E2 and prostacyclin are
of interest. The aim of the current projects is to explore the subunit composition and role
of these ion channels and receptors in pial and meningeal arteries and trigeminal
ganglion. We have during the last three months of the year initiated three new projects. In
these projects we investigate C-Fos expression after infusion of migraine triggering
substances, the occurrence and mechanisms behind CGRP uptake in migraine relevant
tissue and to investigate the presence and role of the proteinase activated receptor-2 in
migraine relevant tissue. The studies will give us an understanding of which subtype
compositions of ion channels and receptors that are present in theses tissues. In addition,
they will give us information to further understand the pathophysiology of migraine and to
define new targets for the pharmacological treatment of migraine.

Idiopathic intracranial hypertension
Members
Rigmor Jensen, Maren Skau.
Background
Idiopathic intracranial hypertension (IIH) is an intriguing, clinical condition of increased
intracranial pressure without pathological, laboratory or radiological evidence of
intracranial pathology in young, obese individuals. The clinical symptoms are severe
headache, pulsatile tinnitus, transitory visual obscurations and diplopia. Demographic
14 Danish Headache Center · Annual Report 2008
studies report a rapidly increasing incidence of IIH in obese young females and with the
global epidemic increase of obesity a significant increase in the number of IIH patients in
Denmark can be predicted. Severe obesity is closely related to a number of
neuroendocrinological changes which has still not been evaluated in IIH.
Untreated IIH may lead to severe visual loss and blindness resulting from damage to the
optic nerve. The mechanism whereby IIH leads to optic nerve dysfunction is poorly
understood but it seems to be closely linked to edema of the optic nerve head and the
associated elevation of hydrostatic pressure inside the optic nerve.
The multidisciplinary study of IIH comprising neurobiological and ophthalmological
aspects is a unique study of still unsolved aspects in IIH. Read more about IIH on
www.danishheadachecenter.com.

Medication-overuse headache
Members
Signe Bruun Munksgaard, Rigmor Jensen, Lars Bendtsen.
Background
Medication-overuse headache (MOH) is a daily or almost-daily type of headache that
usually results from the chronification of primary forms, such as migraine or tension-type
headache, as a consequence of the progressive increase in the intake of symptomatic
drugs. MOH affects a percentage of 1.4-3% of the general population. Limited amount of
data exists on the burden of MOH, even in developed Countries, but there is general
agreement that the disease represents one of the most disabling disorders, which
markedly deteriorates the quality of life of patients, exposing them to the risks of side-
effects and co-morbid conditions.
Danish Headache Center · Annual Report 2008 15
Our knowledge on the mechanisms leading to MOH are limited, and there are virtually no
data on how these severely patients are treated optimally. Thus, there is an urgent need
for studies investigating the pathophysiology and treatment possibilities of MOH.
Current projects
A prospective study comparing two different treatment options for MOH (abrupt drug
withdrawal and a 2 month drug free period compared with restricted intake of analgesics
combined with prophylactic headache treatment).
A prospective study investigating pain modulation (peripheral and central pain sensitivity)
before and after drug withdrawal.
An EU-founded multi-centre study (COMO-ESTAS) investigating the benefit of electronic
headache diaries during detoxification of MOH.
