Salivary DNA analysis shows exercise reduces genetic risk for depression and suicidal ideation
A genetic risk factor for major depression and suicidal ideation is mitigated by physical activity Author: Taylor MK, et al. (2017), Psychiatry Research We evaluated associations of five candidate polymorphisms (Bcl1 [rs41423247], -2C/G [rs2070951], COMT [rs737865], Val66Met [rs6265], and 5HTTLPR [biallelic and triallelic [5HTTLPR/rs25531]) with probable MDD and suicidal ideation (SI), the effects of physical […]
Study demonstrates combined effects of salivary cortisol & DHEA-S in predicting depressive symptoms
Concurrent and prospective associations between HPA axis activity and depression symptoms in newlywed women Author: Ge F, et al (2016), Psychoneuroendocrinology. We investigated the extent to which individual differences in activity of the hypothalamic pituitary adrenal axis (HPA) are associated with depressive symptoms among newlywed couples.
