“…Associations between anxiety proneness and somatic phenotype were suggested by Uvnäs-Moberg (Uvnäs-Moberg et al 1993), who also reported correlations between circulating gastrin and anxiety. In a previous study, we demonstrated that both basal and pentagastrinevoked C-peptide levels correlated to panic-like experience (Radu et al 2002).…”

“…Healthy individuals and patients with panic disorder show interindividual variation in response to biological challenges such as administration of CCK B receptor agonists (Abelson et al 1991;Bradwejn et al 1991), voluntary hyperventilation (Rapee and Medoro 1994), CO 2 inhalation (Ley 1991;Eke and McNally 1996;Antony et al 1997;Bystritsky et al 2000) and epinephrine infusion (van Zijderveld et al 1999). These variations might be associated with personality traits, such as various aspects of trait anxiety and anxiety sensitivity, which in turn might be related to a certain phenotype (Uvnäs-Moberg et al 1993;Koszycki and Bradwejn 2001). Trait anxiety is the general tendency to respond anxiously to a wide range of stressors, state anxiety describes the amount of anxiety experienced at a particular moment, whereas anxiety sensitivity refers to fear of anxiety sensations (McNally 1996).…”

“…To date five studies have investigated the relationship between OT secretion or concentration and temperament or personality. These studies have reported inconsistent findings (Uvnas-Moberg et al, 1990;UvnasMoberg et al, 1991;Uvnas-Moberg et al, 1993;van Londen et al, 1997;Turner et al, 1999), although only some included measures involving socially affiliative behaviour.…”

Plasma oxytocin levels in depression and their correlation with the temperament dimension of reward dependence

Evidence suggests that the neuropeptide oxytocin plays a role in social affiliation. This behaviour may be related more to personality dimensions than specific psychiatric diagnoses. This study investigated the relationship between plasma oxytocin levels and personality dimensions using the Temperament and Character Inventory (TCI) in 60 outpatients with major depression. The strongest correlation was between plasma oxytocin levels and the temperament dimension of Reward Dependence (0.425 Pearson correlation). This suggested that 17% of the variance in plasma oxytocin levels was explained by the Reward Dependence scores. There was a significant positive correlation between plasma oxytocin levels and the Reward Dependence personality dimension.

“…However, no interactions with meal type were reported in these regression analyses, and indeed, changes in gastrin were unrelated to meal type in any case. Wells et al (1997) suggested that the negative correlations between gastrin and fatigue-sleepiness may reflect less fatigue-sleepiness in more anxious subjects throughout the study, since trait anxiety has been associated with higher gastrin levels (Uvnas- Moberg et al 1993). Certainly, without differential effects of meal type, it seems likely that personality will be an important mediating variable.…”

The impact of nutritional variation, within populations not overtly malnourished, on cognitive function and arousal is considered. The emphasis is on susceptibility to acute effects of meals and glucose loads, and chronic effects of dieting, on mental performance, and effects of cholesterol and vitamin levels on cognitive impairment. New developments in understanding dietary influences on neurohormonal systems, and their implications for cognition and affect, allow reinterpretation of both earlier and recent findings. Evidence for a detrimental effect of omitting a meal on cognitive performance remains equivocal: from the outset, idiosyncrasy has prevailed. Yet, for young and nutritionally vulnerable children, breakfast is more likely to benefit than hinder performance. For nutrient composition, despite inconsistencies, some cautious predictions can be made. Acutely, carbohydrate-rich-protein-poor meals can be sedating and anxiolytic; by comparison, protein-rich meals may be arousing, improving reaction time but also increasing unfocused vigilance. Fat-rich meals can lead to a decline in alertness, especially where they differ from habitual fat intake. These acute effects may vary with time of day and nutritional status. Chronically, protein-rich diets have been associated with decreased positive and increased negative affect relative to carbohydrate-rich diets. Probable mechanisms include diet-induced changes in monoamine, especially serotoninergic neurotransmitter activity, and functioning of the hypothalamic pituitary adrenal axis. Effects are interpreted in the context of individual traits and susceptibility to challenging, even stressful, tests of performance. Preoccupation with dieting may impair cognition by interfering with working memory capacity, independently of nutritional status. The change in cognitive performance after administration of glucose, and other foods, may depend on the level of sympathetic activation, glucocorticoid secretion, and pancreatic ␤-cell function, rather than simple fuelling
