Headache is the most common neurological complaint accounting for % 1 to % 4 in the emergency department (ED).Every year, nearly one million people with headache attacks have been consulted by healthcare professionals at the emergency room in the United States.The International Classification of Headache Disorders (ICHD) divided headaches into two main groups: primary headaches and secondary headaches. The vast majority of cases who presented with acute headache attack in ED had a diagnosis of primary headache disorders (tension- type headache, migraine, cluster- type headache, and other primary headaches). However, secondary headache is often associated with underlying intracranial pathologies, and noted in % 10 of cases in emergency rooms. Despite the frequent presence of primary headaches, limited time setting and busy periods of medical assessment, leading diagnostic and therapeutic options due to the pathophysiological factors to be overlooked. To date, no study in the emergency care setting has explored the role of inflammation in patients with acute migraine and TTH. Investigators aimed to explore inflammatory markers [white blood cells (WBC), neutrophil, lymphocyte, platelet, neutrophil / lymphocyte ratio (NLR), and platelet / lymphocyte ratio (PLR)] in complete blood count (CBC) among MA, MO, and TTH participants who admitted to ED with acute headache attack and healthy volunteers.
The investigators plan to evaluate long-term consequences of unintentional dural puncture in women who had this complication during labor epidural insertion at Mount Sinai Hospital. A dural puncture is the perforation of the dura mater (one of the layers protecting the brain and the spinal cord) by the needle that is used to find and place a catheter in the epidural space. A puncture will cause a leakage of cerebrospinal fluid through the dura that results in an acute and usually self-limited headache in half of patients who have this complication. The usual treatment for this complication is conservative with the use of oral medications like acetaminophen, anti-inflammatory and narcotics. In the severely symptomatic patient, the injection of blood in the epidural space is a more invasive approach performed to "patch" the hole that was created in the dura (epidural blood patch). The objective is to determine whether or not there is a risk of developing long-term effects from the unintentional dural puncture and its treatment by epidural blood patch by comparing women who had a dural puncture during their labour epidural insertion with or without an epidural blood patch with women who received an epidural but did not have a dural puncture during the same period of time. The hypothesis is that women who had unintentional dural punctures during epidural insertion will develop long-term effects such as chronic headache, chronic backache, chronic auditory or visual disturbances and chronic disability more frequently than women who received an epidural but did not sustain a dural puncture. The investigators also hypothesize that the use of epidural blood patch may change the course of these complications.
Observational analytic study with prospective cohort design that aim to describe the presence of typical features of migraine in a cohort of nummular headache patients. The aim of the study is to analyze family history, epidemiology, clinical description, presence of prodromes, postdromes and response to treatment.
To investigate the glutaminergic system in the onset of migraine-like attacks.
Headaches are extremely common illnesses with a combined lifetime prevalence of 90-99% in Europe. Despite this high prevalence, there are persons who have never, in their whole life, encountered a headache. The aim of the study is to identify factors that protect against headache by studying multiomics in people who never have had a headache (headache resistant) versus non-resistant controls. The investigators will measure multiomic changes (transcriptomics and metabolomics) after pain induction by Cold Pressor Test. 3 blood samples, two for RNA and one for metabolites are taken 5 minutes before a Cold Pressor Test and again 1 hour after the Cold Pressor Test. The investigators hope to contribute with novelty to the current understanding of headache pathophysiology and development of more efficient treatment of headache.
The purpose of the study is to investigate whether a questionnaire can be used to detect whether patients referred to the Danish Headache Center have a painful temporomandibular disorder (TMD). TMD is a major public health problem that affects up to 15% of the adult population and can cause headaches that can be immediately difficult to differentiate from other headache types such as tension headaches and migraines. By applying the so-called diagnostic criteria for TMD through a standardized study program, TMD diseases such as myalgia of the jaw muscles, arthralgia and discus displacements of the jaw joints and jaw arthritis can be diagnosed. However, this requires dental expertise and is time consuming. At the Danish Headache Center, the current screening question is used for TMD in order to identify who could benefit from further investigation in dentistry. But it is still unknown how accurate these questions are in selecting those patients who have TMD diseases in a patient group with a headache. The investigators would like to investigate this in order to improve the referral procedure of headache patients for relevant dental treatment or physiotherapy. This is believed to be of importance both in a specialized unit such as the Danish Headache Center and in neurological medical practice. Patients will be recruited who are referred to the Danish Headache Center, who have been given TMD screening questions and who have indicated in writing that they wish to be contacted for research projects. In the study, 25 subjects with TMD screening question score of ≥ 3 points will be included, which will be gender and age matched with 25 subjects who have TMD screening question score of <3 points. The patients will be interviewed to classify the patients headache 15 min and then have a jaw examination done and then the DC / TMD examination will be done and lasts approx. 30 min. The examination is performed by a skilled physiotherapist and it does not involve any side effects or risks.
This study uses a single questionnaire to evaluate two separate primary outcomes: 1. To identify association between chronic headache in women who have given birth to children as compared to a control group of women who have raised children but have not given birth to them 2. To identify association between chronic back pain in women who have given birth to children as compared to a control group of women who have raised children but have not given birth to them
To what extent the somatotopy of the 3 branches of the trigeminal nerve (V1,V2,V3) as well as the greater occipital nerve (GON) in the brainstem but also in the thalamus and the insula can be mapped using functional imaging and BOLD in humans is not known but might play an important role in imaging headache diseases. The aim is to map their somatotopy by random stimulation of V1, V2, V3 and the GON with painful electrical input during acquisition of BOLD-fMRI.
Vasoactive intestinal peptide (VIP) is a peptide of 28 amino acid residues that belongs to the glucagon/secretin superfamily of peptides. It is produced in different regions of the nervous system, including the brain, trigeminovascular system and several autonomic nerves. Once released from neurons, it acts on vasoactive intestinal peptide receptor 1 (VPAC1), vasoactive intestinal peptide receptor 2 (VPAC2) and pituitary adenylate cyclase-activating polypeptide type I receptor (PAC1), by mediating smooth muscle relaxation, vasodilation and water secretion. Along with other neuropeptides, such as calcitonin gene-related peptide (CGRP) and pituitary adenylate cyclase-activating polypeptide (PACAP), it is released from the trigeminal afferents and exerts a strong vasodilating activity on the cranial vasculature, sharing the activation of adenylate cyclase. Especially, it shares 70% structure with PACAP and acts on the same receptors. But, unlike it, VIP cannot induce a long-lasting vasodilation and has a modest capability to induce migraine attacks. Whether a long-lasting infusion of VIP may induce a prolonged vasodilation in the cerebral vessels and migraine, as a twenty-minute infusion of PACAP, is unknown.
