Explain the rationale used for sleep deprivation as a treatment for depression
What will be an ideal response?
Answer: Depression is accompanied by disorder of sleep in which sleep is shallow and fragmented. REM sleep comes on earlier in the night, and the first half of the night contains more REM periods. Sleep deprivation, either total deprivation or deprivation of REM sleep only, can alleviate depression. The suppression or delay of REM sleep appears to be involved in alteration of mood. Drugs that suppress REM sleep are antidepressant, and ECT both lifts mood and suppresses REM sleep.
