Intracranial abnormalities and headache: A population-based imaging study (HUNT MRI).

Area of Science:

• Neurology
• Epidemiology
• Radiology

Background:

• Previous research on intracranial abnormalities in headache sufferers often focused on specific clinical groups.
• This study aimed to investigate the link between intracranial abnormalities and headaches in a general middle-aged population.

Purpose of the Study:

• To determine the association between intracranial abnormalities and headache prevalence in middle-aged adults within the general population.

Main Methods:

• Utilized data from the HUNT 3 study (epidemiological) and HUNT MRI (imaging) involving 864 participants aged 50-65.
• Headache types (migraine, tension-type, unclassified) were categorized based on questionnaire responses.
• Logistic regression analysis compared the incidence of intracranial abnormalities between headache groups and a headache-free control group.

Main Results:

• Intracranial abnormalities were more frequent in individuals experiencing headaches (29%) compared to those without (22%).
• Tension-type headache sufferers exhibited increased odds of minor intracranial abnormalities (OR, 2.13).
• This association was primarily linked to white matter hyperintensities, and the significance diminished upon their exclusion.

Conclusions:

• Headache sufferers, particularly those with tension-type headaches, have a greater likelihood of presenting with minor intracranial abnormalities.
• White matter hyperintensities were identified as a key factor contributing to this increased association.
