MMPI characteristics associated with cerebral palsy and dystonia musculorum deformans
Abstract:
The origins of dystonia musculorum deformans are now considered to be organic. However, misdiagnosis of dystonia as a functional psychiatric disorder--usually conversion reaction--has persisted. The present study describes personality traits as measured by the Minnesota Multiphasic Personality Inventory in 30 persons with dystonia and in a control group of 37 persons with cerebral palsy. The data, examined by diagnosis, level of disability, and sex, showed no differences for diagnostic groups or levels of disability. Males scored in the direction of greater psychopathology than did females. The male dystonics showed the highest elevations of MMPI scales of all the groups. Although only one person with dystonia musculorum deformans and none with cerebral palsy produced the profile usually associated with conversion reaction, 36% of all profiles showed two scales above a T score of 70. This finding suggested that young adults with a physically disabling disease may be at higher risk for developing maladaptive personality traits.
Insights
Dystonia musculorum deformans is organic, but often misdiagnosed. This study found no personality differences between dystonia and cerebral palsy patients, but males showed more psychopathology, suggesting physical disability may increase maladaptive traits.
Area of Science:
- Neurology
- Psychiatry
- Psychology
Background:
- Dystonia musculorum deformans is an organic neurological disorder.
- Misdiagnosis as a functional psychiatric disorder, specifically conversion reaction, remains a challenge.
- Understanding personality traits in dystonia patients is crucial for accurate diagnosis and management.
Purpose of the Study:
- To investigate personality traits in individuals with dystonia musculorum deformans.
- To compare personality profiles of dystonia patients with a control group.
- To explore potential links between physical disability and personality characteristics.
Main Methods:
- Utilized the Minnesota Multiphasic Personality Inventory (MMPI) to assess personality traits.
- Recruited 30 individuals diagnosed with dystonia musculorum deformans.
- Included a control group of 37 individuals with cerebral palsy for comparison.
Main Results:
- No significant differences in personality traits were found between the dystonia and cerebral palsy groups.
- No differences were observed based on the level of disability.
- Male participants, particularly those with dystonia, exhibited higher scores for psychopathology on MMPI scales.
- While conversion reaction profiles were rare, 36% of all participants showed elevated MMPI scales, suggesting potential maladaptive traits.
Conclusions:
- Personality differences do not distinguish dystonia from cerebral palsy.
- Male dystonia patients may be at higher risk for psychopathology.
- Young adults with disabling physical conditions might be more susceptible to developing maladaptive personality traits.
