Background: Sex influences is important to understand behavioral manifestations in a large number of neuropsychiatric disorders. We found electrophysiological differences specifically related to the influence of sex on psychopathic traits. Methods: The resting electroencephalography (EEG) activity and low-resolution brain electromagnetic tomography (LORETA) for the EEG spectral bands were evaluated in 38 teenagers with conduct disorder (CD). The 25 male and 13 female subjects had psychopathic traits as diagnosed using the Antisocial Process Screening Device. All of the included adolescents were assessed using the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR) criteria. The visually inspected EEG characteristics and the use of frequency-domain quantitative analysis techniques are described. Results: Quantitative EEG (QEEG) analysis showed that the slow-wave activities in the right frontal and left central regions were higher and the alpha-band powers in the left central and bitemporal regions were lower in the male than the female psychopathic traits group. The current source density showed increases in paralimbic areas at 2.73 Hz and decreases in the frontoparietal area at 9.37 Hz in male psychopathics relative to female psychopathics. Conclusions: These findings indicate that QEEG analysis and techniques of source localization can reveal sex differences in brain electrical activity between teenagers with CD and psychopathic traits that are not obvious in visual inspections.

본 연구는 정신병질 특성을 가지고 있는 집단이 정서적 얼굴을 처리하는 데 있어서 어떤 차이가 있는지 알아보았다. 정신병질적 성격 검사 개정판에 따라 15명의 정신병질 특성집단과 15명의 통제집단을 선별하였다. 실험 참여자들은 화남, 공포, 슬픔으로 구성된 부정적 얼굴과 무표정인 중성적 얼굴이 자극으로 사용된 과제를 수행하였다. 피험자가 자극의 성별을 판단하는 암묵적 과제와 정서를 판단하는 외현적 과제를 수행하는 동안 사건관련전위가 측정되었다. 정서처리과정에서 나타나는 정신병질 특성집단과 통제집단의 차이를 조사하기 위해 LPP(late positive potentials) 진폭을 분석하였다. 암묵적 과제에서는 두 집단 간 유의미한 차이가 나타나지 않았다. 그러나 외현적 과제에서는 집단과 정서 간 유의미한 상호작용이 전두중심영역에서 나타났다. 부정적 얼굴과 중성적 얼굴에서 비슷한 LPP 진폭을 보인 통제집단과 다르게 정신병질 특성집단은 부정적 얼굴에 비해 중성적 얼굴에서 더 큰 진폭을 보였다. 이러한 결과는 정신병질 특성집단이 가지는 정서 처리의 비정상성을 반영한다고 볼 수 있다.

Objectives: The current study investigated the personality characteristics of parents of children with attention-deficit hyperactivity disorder (ADHD) using the Minnesota Multiphasic Personality Inventory (MMPI), which is commonly used in clinical medicine. Methods: Participants were 117 parents of children with ADHD (96 boys and 21 girls) and 77 parents of comparison children (50 boys and 27 girls), who completed the Korean version of the MMPI. Results: The MMPI scores of the fathers of ADHD children were significantly higher on the Psychopathic Deviate (Pd), Masculinity-Femininity (Mf), Paranoia (Pa), and Psychasthenia (Pt) scales than the comparison group's were. In addition, the mothers of ADHD children had higher MMPI scores on the traits of Hypochondriasis (Hs), Psychopathic Deviate (Pd), and Schizophrenia (Sc) than the comparisong roup had, but were not significantly higher. Conclusion: The fathers of ADHD children might be antisocial, irresolute, passive, paranoid, and anxious. In addition, mothers of ADHD children might have hypochondriacal, antisocial, and/or psychological confusional traits, but these were not be significantly high. These results suggest that the psychopathology of parents of ADHD children might correlate with their children's ADHD.
