Rapid shifts in mood over brief periods are called?

• A. Lability
• B. Mood descriptors
• C. Delirium
• D. Psychotic features

Answer: (D)

Mood lability is the rapid shifts in mood over short periods. It means emotions swing quickly—from happy to sad or irritable to calm—often within minutes to hours and may not align with the surrounding situation. This pattern is seen in various conditions and reflects emotional instability rather than a specific content of thought. Delirium involves fluctuating attention and cognition with changes in consciousness, not just mood shifts. Mood descriptors are simply terms used to label how someone feels, not the rapid fluctuation itself. Psychotic features refer to symptoms like delusions or hallucinations, which are about content of thought, not the speed of mood change. So the phenomenon described is best captured by mood lability.
