Part 1 established the historical transition of Persistent Postural-Perceptual Dizziness (PPPD) into the framework of Functional Neurological Disorders (FND).
Isn't "The patient begins to perceive movement through their body that a healthy individual would never recognize. They sense micro-vibrations, subtle sways, or minor shifts in their environment and interpret them as significant motion. They start to ‘feel’ their way through space. This hyper-perception of body-felt movement is a learned, maladaptive strategy. The system designed to keep them steady is now the very system they use to sense a perceived threat of movement." Same as MdDA?
In MDDS, you have a VSI that says I am moving when you aren't. In PPPD, you have a VSI that is getting fed bad data from the eyes and body because the vestibular system is untrustworthy. In both cases, the patient's anxiety creates a hypervigilant state.

Interesting - MdDS and PPPD, in my opinion, are two sides of the same coin, but with different problems at the Velocity Storage Integrator.
