NARCOLEPSY

SCF-RDOS ENCYCLOPEDIA ENTRY

Classification

DEFINITION

Narcolepsy is a chronic neurological sleep-wake disorder characterized by excessive daytime sleepiness, abnormal regulation of rapid eye movement (REM) sleep, and instability of wakefulness mechanisms.

The disorder results from dysfunction of neural systems responsible for maintaining wakefulness and regulating transitions between sleep and wake states. In many individuals, particularly those with Narcolepsy Type 1, loss of hypothalamic orexin (hypocretin)-producing neurons is a central pathogenic mechanism.

Core manifestations may include:

• Excessive daytime sleepiness
• Irresistible sleep attacks
• Cataplexy
• Sleep paralysis
• Hypnagogic hallucinations
• Fragmented nighttime sleep
• Cognitive impairment
• Fatigue

Within the SCF framework, Narcolepsy is conceptualized as a sleep-state boundary instability disorder involving dysfunction across orexin-regulation networks, REM-control circuits, wakefulness-maintenance systems, neuroimmune pathways, and circadian synchronization mechanisms.

ETIOPATHOGENIC CORE

Primary Pathogenic Theme

Loss or dysfunction of orexin-mediated wakefulness regulation destabilizes sleep-state boundaries, allowing REM-sleep phenomena to intrude into wakefulness and producing chronic hypersomnolence.
