    Abstract : Experiences of early adverse life events are more frequent among adult depressed patients than healthy subjects. Studies with non-human primates and rats show that maternal deprivation leads to changes in hypothalamic-pituitary adrenal (HPA)-axis activity/reactivity and increased levels of anxiety and alcohol preference.

  3. 3. Self-rated health : Biobehavioral determinants with focus on inflammatory factors

    University dissertation from Stockholm : Karolinska Institutet, Department of Neurobiology, Care Sciences and Society

    Author : Anna Nixon Andreasson; Karolinska Institutet.; Karolinska Institutet.; [2010]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Self-rated (subjective) health is an independent predictor of future mortality, but neither the mechanisms behind this relation nor the biological determinants of poor self-rated health are known. Inflammatory cytokines give rise to a sickness response which includes fatigue, malaise, anhedonia and pain, resembling factors that are known to impact negatively on self-rated health. READ MORE

    Abstract : Considering the heterogeneous character of depression, it seems likely that many brain regions are involved mediating the diverse symptoms of depression. For example, the mesolimbic DA system has a central function for motivational behaviors and pleasure seeking, and it is possible that malfunctioning of brain reward systems could be an underlying mechanism of the anhedonia experienced in depressive illness.
