Sleep apnea involves pauses in breathing during sleep, causing poor sleep quality but not sudden overwhelming daytime sleepiness with unintended naps. Insomnia is difficulty falling or staying asleep, the opposite of excessive sleepiness. Night terrors are episodes of screaming/fear during deep sleep, unrelated to daytime sleepiness. Narcolepsy is characterized by overwhelming, sudden daytime sleepiness and involuntary sleep attacks (like falling asleep at a desk).
