Delayed diagnosis of narcolepsy: characterization and impact.

Highlights: [•] Narcolepsy is a chronic neurologic condition, which frequently has an early onset. [•] A long delay until diagnosis has been consistently reported in the literature. [•] Studies report a mean delay of up to 15years, with individual cases of >60years. [•] The underlying reason for diagnosis delay is likely a lack of symptom recognition. [•] We highlight closing this diagnostic gap through awareness of narcolepsy symptoms. [Copyright &y& Elsevier]
