A study by the University of Valencia (UV) and the INCLIVA Health Research Institute, of the Clinical Hospital of Valencia, shows that stress during the early stages of life can modify the brain, particularly in women. The study, led by Juan Nácher, Professor of Cell Biology and a member of the INCLIVA Psychiatry and Neurodegenerative Disease Research Group, suggests that the impact of adverse and stressful experiences is especially important in the early years of life, as certain regions of the brain, especially the prefrontal cortex, are still developing.
Consequently, aversive experiences that occur during childhood or adolescence can cause long-term alterations in neural connections and their functioning and associated behaviors, highlights the research published in the journal Neurobiology of Stress.
Although sex influences the stress response and women are more likely to develop related psychiatric disorders, knowledge about the effects of stress on women is still limited, according to work led by Nácher, who is also a researcher of the Networked Biomedical Research Center on Mental Health (CIBERSAM).
To analyze the long-term effects of stress in early life on the neural circuits of the prefrontal cortex and to find out whether sex has an influence on them, we made male and female mice undergo stressful experiences during the later stages of childhood and adolescence. The results showed that stress in early life has a very important effect on the neural circuits of the prefrontal cortex, especially in females.
