Early life hormonal environment and neurodevelopmental disorders | EPICSS

Autism is 2-4 times more prevalent in males than females which implies that factors in sexual differentiation, such as sex hormones during early life, might be important for the development of this disorder. Other neurodevelopmental disorders such as Attention deficit/hyperactivity disorder are also more prevalent in males than females.

This project explores the role of early life hormonal exposure, particularly sex hormones exposure, on the risk of autism and other neurodevelopmental disorders using a combination of register-data and bio-samples.
