Narcolepsy is a chronic neurological disorder that affects the brain's ability to regulate the sleep-wake cycle. If you experience overwhelming daytime sleepiness or sudden muscle weakness, a sleep specialist can help.
Types of Narcolepsy
- Type 1 (with cataplexy) — includes sudden muscle weakness triggered by emotions
- Type 2 (without cataplexy) — excessive sleepiness without cataplexy
Symptoms of Narcolepsy
- Excessive daytime sleepiness — the hallmark symptom
- Cataplexy — sudden loss of muscle tone triggered by laughter, surprise, or anger
- Sleep paralysis — temporary inability to move when falling asleep or waking
- Hypnagogic hallucinations — vivid dream-like experiences at sleep onset
- Disrupted nighttime sleep
Diagnosis
Diagnosing narcolepsy requires:
- Overnight polysomnography — to rule out other sleep disorders
- Multiple Sleep Latency Test (MSLT) — measures daytime sleep tendency
- Clinical evaluation and detailed symptom history
Treatment Options
- Wake-promoting medications
- Sodium oxybate — for cataplexy and nighttime sleep
- Scheduled naps — strategic short naps can improve alertness
- Lifestyle modifications — regular sleep schedule, avoiding alcohol
