  2. 6. Serotonin in Fear and Anxiety

    Author : S Melker Hagsäter; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; serotonin; anxiety; fear; SSRI; IBS;

    Abstract : That the neurotransmitter serotonin (5-HT) has a central role in fear and anxiety is supported by numerous experimental and clinical studies. Arguably the most illustrative example is the effect of serotonergic-acting drugs, and in particular the selective serotonin reuptake inhibitors (SSRIs), in the treatment of anxiety disorders.

  4. 7. Ovarian hormones and effects in the brain : studies of neurosteroid sensitivity, serotonin transporter and serotonin2A receptor binding in reproductive and postmenopausal women

    Abstract : Background: Estrogen has been reported to enhance well-being and quality of life during the climacteric phase. In women with an intact uterus estrogen treatment is always combined with progestins in order to protect the endometrium from hyperplasia and malignancies. READ MORE

  5. 8. Influence of serotonin on anxiety-like behavior in rat

    Author : Robert Pettersson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anxiety; Serotonin; SSRI;

    Abstract : It is well-established that serotonin is involved in the regulation of mood and behaviour, partly implied by the therapeutic effect of prolonged treatment with selective serotonin reuptake inhibitors (SSRI) on mood and anxiety disorders. However, the mechanisms behind the paradoxical exacerbation of anxiety described during initial treatment, as well as behind the therapeutic effects of prolonged treatment with SSRIs, remain poorly understood.

  6. 9. Anabolic androgenic steroids and central monoaminergic systems : Supratherapeutic doses of nandrolone decanoate affect dopamine and serotonin

    Author : Carolina Birgner; Lena Bergström; Anna Kindlundh-Högberg; Fred Nyberg; Stefan Brené; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacology; anabolic androgenic steroids; nandrolone decanoate; dopamine; serotonin; rat; central nervous system; Pharmacology; Farmakologi;

    Abstract : Supratherapeutic doses of anabolic androgenic steroids (AASs) are administered, not only as performance-enhancing drugs in the world of sports, but also in order to modify behaviour. AAS abusers are at risk of developing serious physical and psychological side effects such as dependence and aggressive behaviour. READ MORE

  7. 10. Influence of serotonin-related genes on behavior and body weight

    Author : Jessica Bah Rösman; Göteborgs universitet; []
    Keywords : Serotonin; Genes; anorexia nervosa; premenstrual dysforia; body weight; suicide; polymorphism; HTR2C; SLC6A4; GATA2; HTR3B;

    Abstract : Rationale: The neurotransmitter serotonin has been implicated in the regulation of normal behaviors, including food intake, and attributed importance for a variety of common psychiatric conditions, including major depression, suicidal behavior, eating disorders and premenstrual dysphoria. The purpose of these studies was to explore the possible influence of genetic variation in serotonin-related genes on a) body weight, b) binding capacity of the serotonin transporter in the brain of suicide attempters and c) a disorder for which numerous findings suggest serotonin to play a key role, i.
