Types
TACs include
- Cluster headache
- Paroxysmal hemicrania (chronic or episodic)
- Short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT)
- Short-lasting unilateral neuralgiform headache attacks with cranial autonomic symptoms (SUNA)
- Long-lasting autonomic symptoms with hemicrania (LASH)
TACs can be differentiated by the length and frequency of recurrence of the headaches.{{cite journal |doi=10.1136/jnnp.2004.036012 |pmid=15716514 |pmc=1739543 |title=Trigeminal autonomic cephalalgias: Fancy term or constructive change to the IHS classification? |journal=Journal of Neurology, Neurosurgery & Psychiatry |volume=76 |issue=3 |pages=301–5 |year=2005 |last1=Goadsby |first1=P J }}
Treatment
Treatment for TACs varies depending on the exact type, but can include medication such as indomethacin (in the case of chronic paroxysmal hemicrania) or acute and prophylactic therapy (in the case of cluster headache).{{cite web|last1=Graff-Radford|first1=Steven|title=Trigeminal Autonomic Cephalalgias|url=https://americanheadachesociety.org/wp-content/uploads/2016/07/Trigeminal_Autonomic_Cephalalgias.pdf|accessdate=12 January 2017|format=slides|archive-date=16 January 2017|archive-url=https://web.archive.org/web/20170116143908/https://americanheadachesociety.org/wp-content/uploads/2016/07/Trigeminal_Autonomic_Cephalalgias.pdf|url-status=dead}}
