Diagnostic Criteria for Infrequent Episodic Tension-type Headache (ICHD-II Classification link to http://216.25.100.131/upload/CT_Clas/ihc_II_main_no_print.pdf)
|
|
Tension type headaches is the most common type of headache and as many as 30% to 78% of the general population experience at some time during their lifetime. Studies further suggest that there is a biological mechanism underlying these types of headaches and they are not psychogenically based. The exact mechanisms are not known, but peripheral pain mechanisms are most likely involved.
Tension-type headaches occurring frequently or even daily are classified as chronic tension-type headaches and are a serious condition that is associated with headache-induced disability and significantly impacts quality of life. Pain mechanisms peripherally and centrally may be involved in chronic tension-type headache, making treatment more challenging.

- Headache attacks last from 15 to 180 minutes and occur once every other day to up to 8 times daily.

Classification Criteria for Cluster Headache
(ICHD-II criteria link to http://216.25.100.131/upload/CT_Clas/ihc_II_main_no_print.pdf) |
|
- In about 5% of the cases, cluster headache may be hereditary
- Attacks occur in clusters or periods with weeks or months between new cluster periods; remission periods may be months or even years
- 10-15% of patients do not experience long periods of remission
- During a cluster period, attacks may be provoked or triggered by alcohol or selected drugs like histamine or nitroglycerin
- Pain usually presents on the same side each attack
