A patient's face and voice both convey markedly less emotion than expected throughout the interview, including reduced vocal tone variation, and this is not confined to any specific pattern of physical gesture; the patient does not notice any change in themselves. Before revealing the answer: is this a disorder of expressive movement?
No, this is more consistent with blunting of affect than a disorder of expressive movement specifically. The disturbance here spans facial expression, vocal tone, and gesture broadly, rather than being confined to the physical, bodily expressive-movement domain, and the patient's lack of awareness of the change is also characteristic of affect blunting rather than a disorder of expressive movement.
