“…In the previous studies, the score of novelty seeking revealed a correlation with age in healthy subjects [1] and in patients with MDD [29], and the results of the current study support these findings. However, our results showed a negative correlation between female sex and the score of cooperativeness, whereas Takeuchi et al [30] reported that the female sex is positively associated with this score. Differences in the proportion of female subjects and the background of subjects may be instrumental in the correlation between sex and the score of cooperativeness; in the study of Takeuchi et al, the participants included 106 male and 478 female student psychology majors.…”

Background and Aim: Personality traits and vascular endothelial growth factor (VEGF) levels are both independently correlated with major depressive disorder and depressive mood. However, no studies have reported associations between personality traits and VEGF levels. Thus, we hypothesized that there is a correlation between the results of the Temperament and Character Inventory (TCI) and VEGF levels. Methods: We investigated 179 healthy participants who completed the TCI. We collected a serum sample from each subject and measured each participant's VEGF level by an enzyme-linked immunosorbent assay (ELISA). Simple and multiple regression analyses were performed to examine the correlations between the scores on the seven TCI dimensions and several other factors, including gender, age and VEGF level. Results: A total of 150 subjects completed the examination. Among the dimensions of the TCI, the harm avoidance (HA) scores were negatively correlated with VEGF levels, but there were no significant correlations between the scores for any other dimensions and VEGF levels. The HA score was significantly correlated with sex, age and VEGF level, and single and multiple regression analyses yielded the same results. Conclusion: VEGF may be associated with certain personality factors. This study is the first to demonstrate a direct association between VEGF levels and a dimension of the TCI in healthy subjects.

“…There are studies on the internal consistencies and factor structures of the Japanese versions [19,21,22]. The internal consistency (Cronbach's alpha) in this study was .773 for NS, .788 for HA, .696 for RD, .592 for PS, .802 for SD, .802 for CO, and .796 for ST.…”

Abstract:To evaluate the personality correlates of mobile phone text message use in Japanese youth, university students (N = 232) were distributed a set questionnaires containing the Temperament and Character Inventory and items enquiring their text message use. Greater text messaging was associated with high Novelty Seeking (NS). The results of this study suggest that text message was based on NS.

“…Both subscales showed a similar range of variation in our PD sample, suggesting this is not the reason for a lack of correlation between NS2 scores and VS FDOPA K I values. NS3 appears more trait-like (evidenced by much higher test-rest correlation) than NS2 (Takeuchi et al, 2011), and appears to index those traits (irresponsibility, inability to approach life planfully) most strongly linked to general EXT risk (Krueger and South, 2009). It is particularly notable that only NS3 correlates with impaired decision-making on the Iowa Gambling Task (Álvarez-Moya et al, 2011), which has been linked to increased VS FDOPA K I values (Schlagenhauf et al, 2012).…”

Ventral Striatal Dopamine Synthesis Capacity Predicts Financial Extravagance in Parkinson’s Disease

Impulse control disorders (ICDs), including disordered gambling, can occur in a significant number of patients with Parkinson’s disease (PD) receiving dopaminergic therapy. The neurobiology underlying susceptibility to such problems is unclear, but risk likely results from an interaction between dopaminergic medication and a pre-existing trait vulnerability. Impulse control and addictive disorders form part of a broader psychopathological spectrum of disorders, which share a common underlying genetic vulnerability, referred to as externalizing. The broad externalizing risk factor is a continuously varying trait reflecting vulnerability to various impulse control problems, manifested at the overt level by disinhibitory symptoms and at the personality level by antecedent traits such as impulsivity and novelty/sensation seeking. Trait “disinhibition” is thus a core endophenotype of ICDs, and a key target for neurobiological investigation. The ventral striatal dopamine system has been hypothesized to underlie individual variation in behavioral disinhibition. Here, we examined whether individual differences in ventral striatal dopamine synthesis capacity predicted individual variation in disinhibitory temperament traits in individuals with PD. Eighteen early-stage male PD patients underwent 6-[18F]Fluoro-l-DOPA (FDOPA) positron emission tomography scanning to measure striatal dopamine synthesis capacity, and completed a measure of disinhibited personality. Consistent with our predictions, we found that levels of ventral, but not dorsal, striatal dopamine synthesis capacity predicted disinhibited personality, particularly a propensity for financial extravagance. Our results are consistent with recent preclinical models of vulnerability to behavioral disinhibition and addiction proneness, and provide novel insights into the neurobiology of potential vulnerability to impulse control problems in PD and other disorders.
