Answer

The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) defines narcolepsy as recurrent episodes of irrepressible need to sleep, lapsing into sleep, or napping occurring within the same day. These must have been occurring at least three times per week over the past 3 months. There also must be the presence of at least one of the following: [9]

  • Episodes of cataplexy occurring at least a few times per month

  • Hypocretin deficiency

  • REM sleep latency ≤15 minutes, or a mean sleep latency ≤8 minutes and two or more sleep-onset REM periods (SOREMPs)
