The effects of stress on pregnant women’s gut, child’s brain and adult’s response to stress can have a long-term impact on the brain causing brain disorders. This helps in better intervention and treatment of the disorders.

‘‘By knowing the effects of stress on biological systems, personalized approach to treatment and recovery can be given’.’

Childhood stress increases the chance of developing anxiety, depression, or drug addiction later in life by two to four times, while stress during pregnancy may increase the child's risk of developing autism spectrum disorder, as well as several other psychiatric illnesses. Scientists are discovering more about the mechanisms through which childhood or fetal stress disrupts brain development and leads to these disorders, which may help reveal new therapeutic strategies.




Today's new findings show that:
• In a mouse model of autism spectrum disorder caused by maternal infection during pregnancy, renewing fetal brain immune cells alleviates symptoms of the disorder (Tsuneya Ikezu, abstract 030.09)
• Stress before or during pregnancy can alter gut bacteria in women and mice, which in the mice reduces critical nutrients reaching fetuses' brains (Eldin Jašarevic, abstract 500.14)
• Early life stress changes chromatin structure in a brain reward region in mice, making them more vulnerable to stress as adults (Catherine Pena, abstract 500.01)

• Early life stress accelerates the development of the fear response in young mice, but the effect can be prevented by blocking stress hormone production (Kevin Bath, abstract 499.01)
