Psychogenic movement disorders.

Area of Science:

• Neurology
• Neuroscience

Background:

• Psychogenic (functional) movement disorders present diagnostic challenges, with evolving terminology and definitions.
• The term "functional" is increasingly used, reflecting a focus on the neurobiological underpinnings.
• Diagnosis should be inclusionary, based on specific clinical features, rather than exclusionary.

Observation:

• "Red flags" for psychogenic movement disorders include sudden onset, spontaneous remissions, and clinical variability.
• Neuroimaging reveals impaired limbic-motor connectivity and altered sensory-motor processing.
• Psychological factors are considered, but diagnosis relies on observable clinical signs.

Findings:

• Recent research enhances understanding of the neurobiological mechanisms of these disorders.
• Treatment involves patient acceptance of the diagnosis, cognitive-behavioral therapy, physiotherapy, and pharmacologic options.
• Early diagnosis and treatment initiation are critical for better prognosis, as shorter disease duration correlates with improved outcomes.

Implications:

• Advances in understanding neurobiological mechanisms offer new diagnostic and therapeutic avenues.
• Cognitive strategies and physical rehabilitation show promise in managing psychogenic movement disorders.
• The findings underscore the importance of a multidisciplinary approach for effective patient management.
