The association between central hypersomnia and mood, anxiety, or hyperactivity disorders is common. In addition to a psychotic episode or schizophrenia, NT1 is rarer in the national narcolepsy database and may present with distinct diagnostic and therapeutic challenges. We examined the frequency of NT1 patients diagnosed with psychosis and/or schizophrenia and sought to look for signs of narcolepsy and psychotic illness. Three (4%) NT1 patients were diagnosed with a psychotic episode at age 18. In the re-evaluation (mean duration of 9.8 years), we observed one case with a dual diagnosis of NT1 and schizophrenia. In addition to NT1 and a psychotic episode, two NT1 patients were diagnosed with NT1 and a psychosis. We found that NT1 patients diagnosed before the age of 18 were at a higher risk for psychotic episodes (mean 14.4 years), compared to those that were diagnosed after the age of 18 (mean 8.8 years).
