Chronic aggressive behavior in boys: epigenetic sources?

Chronic aggressive behaviour exhibited by some boys from disadvantaged families may be due to epigenetic changes during pregnancy and early childhood.

Previous work by Tremblay’s team suggest that men with aggressive pasts have one thing in common: the characteristics of their mothers. “They are usually young mothers at the birth of their first child, with low education, often suffering from mental health problems, and with substance use problems,” Tremblay explained. The significant difficulties these mothers experienced during pregnancy and the early childhood of their child may have an impact on the expression of genes related to brain development, the immune system, and many other biological systems critical for the development of their child.
