2. 1. Platelet serotonin function and personality traits in affective disorder

   Author : Jolanta Neuger; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Serotonin; depression; panic disorder; platelets; personality; citalopram;

   Abstract : Serotonin (5-HT, 5-hydroxytryptamine) is a neurotransmitter in the central nervous system which has been implicated m the aetiology and pathogenesis of affective disorders like depression and anxiety disorders. The serotonergic system has been shown to be involved in the modulation of mood, sleep, appetite, libido, energy and cognition and memory functions. READ MORE

5. 3. On the influence of serotonin- and sex steroid-related genetic variation on mood, anxiety, personality, autism and transsexualism

   Author : Susanne Henningsson; Göteborgs universitet; []
   Keywords : serotonin; 5-HTTLPR; TPH2; 5-HT3; sex steroids; androgen receptor; estrogen receptor; genetics; gene-gene interaction; social phobia; anxiety; premenstrual dysphoric disorder; depression; personality; autism; transsexualism; amygdala; emotional perception; life events;

   Abstract : Background: The neurotransmitter serotonin has been related to mood and anxiety, and variation in genes that encode important members of the serotonergic system may hence affect mood- and anxiety-related traits. Sex steroids influence brain development, and variation in genes encoding androgen and estrogen receptors, or enzymes needed for sex steroid synthesis, may be of importance for both personality traits and risk for psychiatric disorders.

6. 4. Psychiatric aspects on acute abdominal pain

   Author : Erik Lexne; Ina Marteinsdottir; Lars Brudin; Per-Olof Nylander; Lars Tanum; Linnéuniversitetet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicin; Medicine;

   Abstract : Introduction: Psychiatric comorbidity is estimated to occur in up to 40% of all patients with somatic disorders, and it can have an influence on patient morbidity and mortality. Approximately 20% of patients who seek care for abdominal pain receive the diagnosis nonspecific abdominal pain, and later develop chronic abdominal pain. READ MORE

7. 5. Importance of serotonin-related candidate genes for human behaviour

   Author : Jonas Melke; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; serotonin; genetics; polymorphism; association study; personality; panic disorder; premenstrual dysphoria; serotonin receptor; serotonin transporter;

   Abstract : Family and twin studies have been consistent in demonstrating that genetic factors are involved in the etiology of most major psychiatric disorders, as well as in various normal personality traits. Mostly due to the efficacy of serotonin-acting drugs, such as selective serotonin reuptake inhibitors (SSRI) and tricyclic antidepressants (TCA), the neurotransmitter serotonin has been implicated in a variety of common psychiatric disorders, including depression, a spectrum of anxiety disorders, and premenstrual dysphoria; moreover, some studies have suggested that also personality is influenced by serotonin.
