The research found that more than two-thirds of the association between cognitive ability in the elderly and cortical thickness was accounted for by differences in IQ decades earlier in childhood.
I hope my son doesn’t face any greater difficulties because of my stressful life experiences.
Sperm doesn’t appear to forget anything. Stress felt by dad—whether as a preadolescent or adult—leaves a lasting impression on his sperm that gives sons and daughters a blunted reaction to stress, a response linked to several mental disorders. The findings, published in a new preclinical study in the Journal of Neuroscience by researchers at the University of Pennsylvania, point to a never-before-seen epigenetic link to stress-related diseases such as anxiety and depression passed from father to child.
While environmental challenges, like diet, drug abuse, and chronic stress, felt by mothers during pregnancy have been shown to affect offspring neurodevelopment and increase the risk for certain diseases, dad’s influence on his children are less well understood. The effects of lifelong exposures to dad on children are even more out of reach.
