REM Sleep Behavior Disorder01:15

REM Sleep Behavior Disorder

REM Sleep Behavior Disorder (RBD) is a sleep disorder characterized by the absence of muscle paralysis that normally occurs during the REM phase of sleep. This absence allows individuals to physically act out their dreams, which are often vivid and disturbing. Common behaviors exhibited during episodes include kicking, punching, and yelling. These actions can be dangerous, potentially leading to injuries for the person with RBD or their bed partner.
RBD is significantly associated with...

Summary

Conversion disorders (CDs) involve neurological symptoms linked to psychological factors. This study found CD patients exhibit impaired motor response inhibition, specifically in controlling unwanted movements.

Area of Science:

  • Neurology
  • Neuroscience
  • Psychiatry

Background:

  • Conversion disorders (CDs) present unexplained neurological symptoms.
  • Previous research suggested motor initiation/execution impairments in conversion paralysis.
  • Aberrant or excessive motor movements are characteristic of certain CDs.

Purpose of the Study:

  • To investigate motor response inhibition deficits in conversion disorder patients with aberrant movements.
  • To assess cognitive functions in these patients.
  • To differentiate cognitive profiles between CD subgroups.

Main Methods:

  • Compared 30 CD patients with 30 matched healthy volunteers.
  • Utilized a go/no go task for motor response inhibition.
  • Administered tests for verbal motor response inhibition, attention, processing speed, memory, visuospatial processing, and executive functions.

Main Results:

  • CD patients showed significantly higher commission errors on the go/no go task.
  • This deficit in motor response inhibition persisted after controlling for attention, depression, and anxiety.
  • No significant differences were found in other cognitive domains.

Conclusions:

  • A specific deficit in motor response inhibition may underlie excessive movements in conversion disorders.
  • Results suggest potential cognitive differences between conversion disorder subgroups, distinct from nonepileptic seizures.
  • Highlights the need for subgroup-specific research in conversion disorders.
