Summary
Cervicogenic headache (CEH) affects 4.1% of adults. This study found CEH is distinct from migraine without aura (MwoA), with different diagnostic criteria and symptoms, suggesting they are not closely related.
Area of Science:
- Neurology
- Epidemiology
- Headache Disorders
Background:
- Cervicogenic headache (CEH) prevalence is poorly understood.
- A common belief suggests a close relationship between CEH and migraine without aura (MwoA), often citing frequent neck symptoms in MwoA.
Purpose of the Study:
- To determine the prevalence of CEH in a general population.
- To investigate the potential pathogenetic relationship between CEH and MwoA.
Main Methods:
- A population-based study of 1838 adults aged 18-65 in Vågå.
- Face-to-face interviews, thorough neck examinations, and application of standardized diagnostic criteria for CEH and MwoA.
- Assessment of cervical abnormality features ('CF').
Main Results:
- CEH prevalence was found to be 4.1%.
- Patients with CEH showed significantly higher 'CF' scores (2.37) compared to MwoA patients (0.93).
- CEH criteria like mechanical provocation were more frequent in CEH, while migraine criteria like photophobia were more prevalent in MwoA.
Conclusions:
- CEH is unlikely to be a subgroup of MwoA.
- The distinct clinical features and diagnostic criteria support CEH and MwoA as separate headache entities.

01:21Aneurysm II: Clinical Manifestations and Diagnostic Studies
Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...
01:22Cerebral Edema ll: Pathophysiology
Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this barrier loses...
01:29Increased Intracranial Pressure ll: Pathophysiology
Increased intracranial pressure (ICP) refers to a potentially life-threatening rise in pressure inside the skull. This usually happens when there is a major change in the volume of brain tissue, blood, or cerebrospinal fluid (CSF) — the three components inside the skull. According to the Monro-Kellie doctrine, if the volume of one component increases, the volumes of the other components must decrease to maintain normal pressure. If this does not happen, ICP rises.The process often begins with...
01:16Vascular Spasm
The vascular phase, also known as vasospasm, is the initial stage of hemostasis, crucial for preventing excessive bleeding when a blood vessel is injured. After a vessel is cut, nerves in the damaged area trigger pain and other sensory impulses. Simultaneously, the smooth muscles in the vessel wall contract, resulting in a vascular spasm. This contraction reduces the vessel's diameter at the injury site, slowing or stopping blood loss through the vessel wall. Vascular spasms typically last for...
01:19Imaging Studies VII: Vascular Imaging
DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...
01:25Glaucoma: Overview
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...
