What effect does Clonazepam have on sleep?

• A. Increases TST, N1, N2 and arousals
• B. Decreases TST
• C. Increases REM
• D. Decreases SWS

Answer: (A)

Clonazepam, a benzodiazepine, tends to lengthen total sleep time and promote sleep onset, but it reshapes sleep by increasing lighter sleep and causing some fragmentation. In practice you’ll see more time in stage N2, some increase in N1, and less deep sleep (N3) and REM. This pattern often comes with a higher arousal index, meaning more awakenings or brief arousals during the night, especially with a long-acting agent like clonazepam. So the description of longer total sleep time together with more time in light sleep stages (N1 and N2) and more arousals best matches its typical effects. It does not increase REM, and while deep sleep may decrease, the combination captured here is the most representative.
