Medication Overuse Headache in the US: A National Cross-Sectional Survey

Area of Science:

• Neurology
• Public Health

Background:

• Medication-overuse headache (MOH) is a common cause of chronic headache.
• Understanding of MOH among the general adult population is not well-documented.

Purpose of the Study:

• To assess the awareness and understanding of medication-overuse headache (MOH) among adults in the United States.
• To identify potential gaps in patient knowledge regarding MOH and its associated risks.

Main Methods:

• A descriptive questionnaire with 18 items was administered to 329 adult participants in the US.
• Data collected included demographics, headache characteristics, medication usage, and awareness of the term 'medication-overuse headache'.
• Descriptive statistics and Mann-Whitney U tests were employed for data analysis.

Main Results:

• Nearly half of participants (47.1%) were aged 18-30 years.
• Tension-type headache was the most frequently reported diagnosis (43.8%).
• A significant proportion of respondents (26.7%) had never heard of medication-overuse headache, including some who reported overusing medications.

Conclusions:

• A considerable number of US adults, including those overusing headache medications, lack awareness of medication-overuse headache (MOH).
• Findings highlight a critical need for enhanced patient education on MOH to improve diagnosis and management.
• Targeted educational initiatives are recommended for patients experiencing frequent headaches and using analgesics or abortive medications.
