Tension-type headache in different age groups at two headache centers.

At two headache centers, one for children and adolescents and the other for adults, we investigated patients aged 5-80 years with episodic or chronic tension-type headache to evaluate the relation between age and headache characteristics as well as analgesics intake. We found an increasing headache frequency and duration, an increasing variability of the headache location, and an increasing frequency of nausea with increasing age. All other headache features did not depend on age. Additionally, our study revealed a marked increase of analgesics use in adults compared to children and adolescents. In conclusion, children, adolescents, and adults referred for tension-type headache show minor differences in some headache features, but a marked change of analgesics intake. The different headache symptoms may be causally related to age, but an influence of medication or other factors must also be considered.
