II. Epidemiology

- Lifetime: 78%
- Annual: 38% of adults
- Age

- Overwork
- Lack of sleep

V. Types
- Episodic Tension Headache (Episodic TTH)
- Recurrent Tension Headaches may progress to chronic Tension Headache (due to Headache Central Sensitization)
- Increased risk of chronic Tension Headache with longer duration Headaches and associated Nausea
- Frequent episodic Headaches occur on at least one day, and up to 14 days per month
- Infrequent episodic Headaches occur less than once per month
- Chronic Tension Headache (Chronic TTH)
- See Chronic Daily Headache
- Present at least half the days of the month
- Persists for 6 months or more
- Associated with high disease burden
- Days of work missed per year averages 27
- Contrast with 9 days per year in episodic Tension Headache
