My name is Casey Kozak, and today we're finishing our discussion of functional neurological disorder and physical exam findings. We're going to now turn to functional sensory loss. But first, it's important to acknowledge that the subjective nature of sensory symptoms means that our physical exam tests will be less reliable than those used for functional weakness or movement disorders. Therefore, it's especially important that we as physicians listen carefully to the symptoms our patients are describing and remain aware of the potential for biases such as suggestion, when taking our histories. Nevertheless, there is certainly utility in physical exam tests as positive findings are present in many patients. W
