Abstract:
A clinical diagnosis of narcolepsy type 1 can be challenging, particularly in relation to cataplexy. Despite its specificity, cerebrospinal fluid (CSF) orexin testing is under-utilised in Australasia. We describe the use of CSF orexin testing in 15 clinically indicated patients from two sleep centres, highlighting its utility in the Australasian context.
