Insomnia is common in tension-type headache (TTH) patients and linked to worse headache symptoms and mental health. Identifying insomnia in TTH is key for better patient management.
Area of Science:
- Neurology
- Sleep Medicine
- Psychiatry
Background:
- Tension-type headache (TTH) is the most prevalent headache disorder.
- Severe TTH can be associated with psychiatric comorbidities and sleep disturbances.
- Population-based data on insomnia prevalence and impact in TTH patients are limited.
Purpose of the Study:
- To determine the prevalence of insomnia among individuals with TTH.
- To investigate the impact of insomnia on headache characteristics and psychiatric comorbidities in TTH patients.
- To analyze data from the Korean Headache-Sleep Study (KHSS).
Main Methods:
- A nationwide, cross-sectional, population-based survey (KHSS) of Korean adults (19-69 years).
- Insomnia was defined using the Insomnia Severity Index (ISI) score ≥ 10.
- Analysis included TTH diagnosis, insomnia status, and associated clinical factors.
Main Results:
- Insomnia prevalence was significantly higher in TTH patients (13.2%) compared to those without headache (5.8%).
- Among TTH patients, insomnia was associated with increased headache frequency, intensity, and impact.
- Insomnia in TTH patients correlated with higher rates of anxiety and depression.
Conclusions:
- Insomnia is a prevalent condition among individuals diagnosed with TTH.
- Insomnia exacerbates headache symptoms and is linked to psychiatric comorbidities in TTH.
- Screening for insomnia is crucial for effective TTH management.

Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
