FND Week: The Fundamentals of Functional Neurologic Disorder

Functional Neurological Disorder is often misunderstood, misdiagnosed, or dismissed entirely but this 2022 paper challenges that thinking. Instead of viewing FND as a single condition, researchers are identifying multiple distinct phenotypes, meaning patients may present in very different ways while still sharing common underlying brain mechanisms. The key idea is that the brain is not structurally damaged but is functioning incorrectly, especially in how it processes movement, attention, and expectation.This episode breaks down what those “new phenotypes” actually look like in real life, why symptoms can feel so real and disabling, and how modern neuroscience is shifting away from outdated psychological explanations toward brain-based models. More importantly, we talk about what this means for rehab. If the issue is how the brain predicts and controls movement rather than strength or damage, then traditional therapy approaches may miss the mark.If you have ever been confused by FND or told a patient their symptoms do not make sense, this episode will change how you see it and how you treat it.Source: Hallett M, Aybek S, Dworetzky BA, McWhirter L, Staab JP, Stone J.
