Precision dynamics of predictive coding in functional neurological disorder

Functional neurological disorder (FND) presents disabling symptoms that fluctuate, migrate across systems, and yet routinely show preserved structural integrity-features that can frustrate diagnosis and patient education. Crucially, these symptoms are genuine and reflect altered brain regulation across multiple systems rather than tissue damage or conscious control. This paper offers a clinically usable account of these puzzles by reframing FND as a disorder of precision control within predictiv
