Which term best captures rapid mood fluctuations?

• A. Labile Affect
• B. Flat Affect
• C. Neglect
• D. Speech Quantity

Answer: (A)

Rapid mood fluctuations are described as labile affect. In the mental status exam, affect is the observer’s appraisal of a patient’s emotional expression. When affect changes quickly and markedly from moment to moment—laughing, then crying, then irritable—often not matching the person’s stated mood, that volatility is called labile affect. This contrasts with flat or blunted affect, where emotional expression is diminished; neglect, which relates to attention or awareness, and speech quantity, which refers to how much someone talks, do not capture this rapid emotional shifting. So the term that best fits rapid mood changes is labile affect.
