Q: What is irritability?

Irritability describes a state of heightened sensitivity to frustration, annoyance, and provocation — where the threshold for reactive upset is lower than usual, minor inconveniences produce disproportionate responses, and patience and tolerance are significantly reduced. It is among the most common symptom presentations across mood, anxiety, neurological, hormonal, and physical health conditions. It is a primary feature of depression in men and children (where it presents more readily than sadness), anxiety disorders, PMS and PMDD, hyperthyroidism, sleep deprivation, chronic pain, ADHD, and withdrawal from substances including alcohol, caffeine, and nicotine.

A state of heightened emotional reactivity, frustration, or annoyance that is disproportionate to triggers or inconsistent with the individual's baseline. Irritability is a transdiagnostic symptom that spans mood, hormonal, neurological, and metabolic conditions.

Quick answer

Irritability (ICD-10: R45.1; ICD-11: MB28) is transdiagnostic across depression, anxiety, PMDD, ADHD, and hormonal conditions. Sleep deprivation is the most common reversible cause. CBT, PMDD-targeted SSRIs, and aerobic exercise have evidence. Mania must be excluded where irritability accompanies elevated mood.
