Summary
This study found that patients with dissociative conversion disorder (DCD) exhibit distinct personality traits, heightened arousability, and impaired decision-making skills compared to healthy individuals. These factors contribute to the psychopathology of DCD.
Area of Science:
- Psychiatry
- Neuroscience
- Psychology
Background:
- Dissociative conversion disorder (DCD) pathogenesis remains poorly understood despite historical recognition.
- Current research on personality and neurocognitive factors in DCD shows inconsistencies.
- This study investigates personality, arousability, and decision-making in DCD patients versus a healthy control group.
Purpose of the Study:
- To explore personality disposition in dissociative conversion disorder.
- To assess arousability and decision-making abilities in DCD patients.
- To compare these factors between DCD patients and a healthy control group.
Main Methods:
- Cross-sectional study design.
- Sample included 10 adult DCD patients and 10 matched healthy controls.
- Assessed personality (Temperament and Character Inventory), arousability (reaction time task), and decision-making (Iowa Gambling Task).
Main Results:
- Significant differences in temperament and character traits were observed in the DCD group.
- DCD patients demonstrated heightened arousability and frustration.
- Deficits in executive function, specifically decision-making ability, were identified in the DCD group.
Conclusions:
- Temperamental and characterological factors are associated with dissociative conversion disorder.
- Cognitive arousability plays a role in DCD psychopathology.
- Impaired decision-making and feedback utilization are implicated in the development of DCD.
