What Irritability Actually Is (And Why It Feels Like Your Nerves Are At You)

Irritability shows up across psychiatry — in depression, ADHD, and autism — but it's almost never the thing researchers build careers around. This episode unpacks the actual mechanism behind that jangly, "my nerves are at me" feeling: a hypersensitive salience network and weakened prefrontal regulation. We explore the NIMH's frustrative non-reward framework, how irritability differs from directed anger, and why the treatment depends entirely on which condition is driving it. From risperidone's massive effect sizes in autism to stimulants' underappreciated benefits for emotional dysregulation in ADHD, we cover what works, what doesn't, and why the same symptom requires completely different approaches depending on its origin.
