The Month That Felt Amazing — and What It Was Really Telling You
Hey Lifeline family,This week's episode was about mood disorders — and I want to start the newsletter with the same number I opened the news segment with.Seventy percent.As in, seventy percent of people with bipolar disorder are misdiagnosed at least once before getting the correct diagnosis. And the average time between first symptoms and accurate diagnosis is ten years.Ten years of the wrong treatment. Ten years of antidepressants that may be triggering cycling. Ten years of a client being told their depression isn't responding when the real issue is that nobody has asked the right question.The right question — which the episode covers in depth — is deceptively simple: has there ever been a period, even one that felt good, when you needed significantly less sleep than usual and had unusually high energy?That question is one of the most clinically important things you will learn to ask. And it's what today's newsletter is built around.The episode covered MDD, Bipolar I, Bipolar II, and Persistent Depressive Disorder — the DSM-5 criteria, the differential diagnosis framework, and the five exam questions. This newsletter goes deeper on all four diagnoses plus the specifier system, the clinical nuances that don't make it into textbooks, and a full differential diagnosis vignette.Let's get into it.— Matt
