SUNCT syndrome. Diagnosis morbi. Shortlasting Unilateral Neuralgiform headache attacks, with Conjunctival injection, Tearing and rhinorrhoea.

The present communication represents an updating of the clinical features of SUNCT. The characteristics of SUNCT have been weighed against other orbital/periorbital headache syndromes towards which differential diagnosis is mandatory. In this group, there are various headaches: cluster headache syndrome, first branch trigeminal neuralgia, and idiopathic stabbing headache (jabs and jolts syndrome). SUNCT emerges as a fairly clear-cut, clinical syndrome. A set of diagnostic criteria of SUNCT syndrome is also given.
