ADHD vs Depression: A Brain Divide or a Bureaucratic Fossil?

Daniel lives with both ADHD and depression, and he noticed something strange: neurologists treat his ADHD, but psychiatrists handle his depression. Why the professional firewall when both conditions show measurable brain changes? This episode explores the real distinction between neurological and psychiatric disorders — and why that line has more to do with history and bureaucracy than biology. We dig into the science of hippocampal volume, default mode networks, and dopamine circuits to understand why ADHD's brain signatures are cleaner than depression's, and why that matters for how patients are treated, how they see themselves, and who manages their care.
