Erratum: HPA axis genetic variation, cortisol and psychosis in major depression

Genetics of HPA-axis, depression and suicidality.

The ultimate consequence of mental ill-health, suicidal behavior (SB), is a significant problem in most societies of the world. Suicide causes about one million deaths worldwide each year, and 10-20 times more people attempt suicide. The causes of why certain people engage in SB are complex, involving for e.g., both environmental and genetic factors, and interactions in-between. Well-establishe...

Diurnal Variation in Peripheral (Hair) vs Central (Saliva) HPA Axis Cortisol Concentrations

Cortisol concentrations in hair and saliva collected from male and female adults over a 15-hour period were compared for differences in overall level and cyclic pattern. Typical diurnal fluctuations were noted for both salivary and hair cortisol, with some individual differences that are congruent with the previous literature. Issues of the link between central and peripheral HPA axes are raise...

Heterogeneity in HPA axis dysregulation and serotonergic vulnerability to depression

Variability in the serotonin transporter (5-HTTLPR) gene can influence the risk of depression associated with adversity, as well as cortisol stress reactivity, although not consistently. No study has examined the impact of both a stressful environment and corticotropic-axis dysfunction on depression, as a function of 5-HTTLPR. This population-based study included 334 subjects aged 65 and older....

Original contribution The HPA axis and perinatal depression: a hypothesis

Episodes of depression and anxiety are as common during pregnancy as postpartum. Some start in pregnancy and resolve postpartum, others are triggered by parturition and some are maintained throughout. In order to determine any biological basis it is important to delineate these different subtypes. During pregnancy, as well as the rise in plasma oestrogen and progesterone there is a very large i...
