Which sleep parameter is affected by antidepressants?

Explanation:
Antidepressants commonly alter REM sleep architecture. They tend to suppress REM sleep by both delaying the first REM period (increasing REM latency) and reducing the overall amount of REM sleep (shorter REM duration and lower REM percentage). Because these drugs typically affect both REM latency and REM itself, the option that includes both is the best choice. Increased sleep efficiency isn’t a consistent or primary effect of antidepressants, and claiming only REM or only REM latency misses the usual pattern.
