Abstract
A solitary patient with symptoms similar to those of shortlasting unilateral neuralgiform conjunctival injection and tearing Short lasting, Unilateral, Neuralgiform headache attacks with Conjunctival injection, Tearing, sweating and rhinorrhoea (SUNCT) was first mentioned in 1978. The term SUNCT was first used in 1991. SUNCT is an acronym; the “S” signifies “Shortlasting”; the “U” symbolizes “Unilateral”; “N” stands for “Neuralgiform”; the “C” for “Conjunctival injection”; and “T” for “Tearing.” The term short-lasting unilateral neuralgiform headache attacks with cranial autonomic symptoms were marketed in 2004. The terminology and new view points are discussed and nosography proposal for SUNCT is presented.
Highlights
This overview deals only with the pure clinical approach to shortlasting unilateral neuralgiform conjunctival injection and tearing Short lasting, Unilateral, Neuralgiform headache attacks with Conjunctival injection, Tearing, sweating and rhinorrhoea (SUNCT) diagnosis
When three cases were known to the authors—worldwide—in 1989, this headache was described in detail, under the heading: “Shortlasting, unilateral neuralgiform headache attacks with conjunctival injection, tearing, sweating, and rhinorrhea” (2)
Shortlasting unilateral neuralgiform conjunctival injection and tearing is a headache taken out of real life; it is a headache based on sound principles
Summary
This overview deals only with the pure clinical approach to shortlasting unilateral neuralgiform conjunctival injection and tearing Short lasting, Unilateral, Neuralgiform headache attacks with Conjunctival injection, Tearing, sweating and rhinorrhoea (SUNCT) diagnosis. Already with only three patients, it was felt that conjunctival injection and tearing probably were the two most spectacular autonomic abnormalities in SUNCT, with a regularity and a vehemence, unlike those of other autonomic abnormalities (6–8). For those reasons, they ought to be treated differently than other autonomic abnormalities, in SUNCT descriptions. SUNCT is the most distinct of the headaches whose birth we have witnessed It should, be emphasized that we never have felt that conjunctival injection and tearing should be obligatory phenomena in SUNCT. In the term SUNCT, as well as in the heading of our 1989 article (2) proposed a probable succession as to prevalence and importance of autonomic variables
