Which statement about sleep deprivation is incorrect?

• A. Depression is a possible side effect.
• B. Forgetfulness is a possible side effect.
• C. Improved mood is a possible side effect.
• D. Cynicism is a possible side effect.

Answer: (C)

Sleep deprivation disrupts mood regulation and cognitive function. When you don’t get enough sleep, your ability to manage emotions and stay attentive declines, often making mood worse and increasing irritability, with a higher risk of depressive symptoms. Forgetfulness appears because sleep is crucial for memory consolidation; without it, attention lapses and memory retrieval become more difficult. Chronic fatigue can also foster cynical attitudes as negative feelings accumulate. An improved mood, on the other hand, is not something sleep deprivation causes; the typical outcome is a decline in mood rather than an enhancement. So the statement about an improved mood being a possible side effect is not correct.
