Consistent with [Hypersomnolence Disorder] [specifier(s)]. For at least three months, there have been excessive sleepiness despite a main sleep period lasting at least seven hours; recurrent daytime sleep episodes; prolonged unrefreshing sleep exceeding nine hours; difficulty becoming fully awake after abrupt awakenings. The presentation is further characterised by sleep inertia, reduced alertness, and cognitive slowing. These symptoms have resulted in clinically significant distress or impairment in social, occupational, or interpersonal functioning, and the disturbance is not better explained by circadian rhythm sleep-wake disorders, insufficient sleep, narcolepsy, obstructive sleep apnoea, other medical conditions, or substance/medication effects.
