Recent Studies from Harvard Medical School Add New Data to Psychology and Psychiatry (Precision dynamics of predictive coding in functional neurological disorder).

This article focuses on recent research from Harvard Medical School regarding functional neurological disorder (FND), a condition characterized by disabling symptoms that fluctuate and affect multiple systems without structural brain damage. The study reframes FND as a disorder of precision control within predictive coding, where the brain’s confidence in its predictions can be dynamically altered by arousal, leading to symptoms such as motor, sensory, cognitive, or visceral disturbances. This framework offers clinicians a mechanistic explanation for symptoms and supports treatment approaches like physiotherapy, psychotherapy, and mindfulness by recalibrating brain prediction weighting. The research aims to unify diagnosis, communication, and treatment planning for FND and has been peer-reviewed. [Extracted from the article]
