Childhood Stress Affects Behavior of Offspring: Mouse Study

Researchers report on the epigenetic effect of early life stress. In a new study, researchers reveal mice who experienced stress in the first few weeks of life showed deterioration in memory, learning and maternal behaviors. Behavioral changes were seen in their later offspring, regardless of sex.

Children Who Experience Violence Early in Life Develop Faster

A new study reports children who are subjected violence early in life experience faster biological aging, including earlier onset of puberty and epigenetic aging, than peers who are not abused. Additionally, children exposed to other early life adversities, such as poverty and food insecurity, show delayed signs of pubertal development.

Chronic cocaine use modifies gene expression

Chronic cocaine use alters the epigenetic profile of the FosB gene in the hippocampus. These alterations are required for cocaine-dependent gene expression and cocaine environment associations. Modification of hippocampal FosB results in a condition critical for cocaine-related learning.

Depression and Schizophrenia May Become Redundant Terms

Using a combination of neuroimaging, genetic research, epigenetics and other biological data in conjunction with artificial intelligence may result in a biological classification of mental illness, rather than diagnosing people based on symptoms alone.
