Excessive daytime sleepiness (EDS) is more common in chronic tension-type headache (TTH) patients. EDS is linked to more frequent, severe TTH, and higher depression rates, impacting quality of life.
Area of Science:
- Neurology
- Sleep Medicine
- Public Health
Background:
- Excessive daytime sleepiness (EDS) is a common complaint linked to headaches.
- Tension-type headache (TTH) is the most prevalent headache type, causing significant disease burden.
- The association between EDS and TTH requires further investigation.
Purpose of the Study:
- To investigate the impact of EDS on the prevalence and clinical presentation of TTH.
- To analyze the relationship between EDS and different TTH subtypes (episodic and chronic).
Main Methods:
- Utilized data from the Korean Headache-Sleep Study, a national survey.
- Identified participants with EDS using the Epworth Sleepiness Scale (score ≥ 11).
- Analyzed TTH prevalence, headache frequency, intensity, impact, and depression rates in relation to EDS.
Main Results:
- EDS was significantly more prevalent in chronic TTH (CTTH) patients (35.7%) compared to those without headache (9.4%).
- EDS prevalence in episodic TTH (ETTH) did not differ significantly from the non-headache group.
- TTH patients with EDS reported higher headache frequency, greater intensity, increased headache impact, and higher depression rates.
Conclusions:
- CTTH is strongly associated with a higher prevalence of EDS compared to ETTH and headache-free individuals.
- EDS exacerbates TTH symptoms, leading to more severe clinical presentations and a greater burden.

Sedatives and Hypnotics Drugs: Miscellaneous Agents
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...
