    Sammanfattning : Anxiety disorders are very common and the primary feature is abnormal or inappropriate anxiety. Fear and anxiety is often mediated by the amygdala, a brain structure rich in substance P (SP) and neurokinin 1 (NK1) receptors. LÄS MER

  3. 2. Serotonin in Fear and Anxiety

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

    Sammanfattning : 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.

  5. 4. Psychiatric and metabolic disturbances in experimental models of Huntington’s disease

    Författare :Sofia Hult Lundh; Translationell neuroendokrinologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Huntington’s disease; huntingtin; hypothalamus; depression; anxiety; metabolism; neuroendocrinology; mouse models; BACHD; rAAV vectors; leptin;

    Sammanfattning : Non-motor symptoms and signs such as metabolic and psychiatric disturbances have been reported to occur early in Huntington’s disease (HD), a fatal neurodegenerative disorder caused by an expanded CAG repeat in the huntingtin gene. However, there is a lack of understanding of the underlying neurobiological mechanisms responsible for the early non-motor features. LÄS MER
