Children exposed to green surroundings may have lower risk of developing ADHD The amount of green space surrounding children's homes could be important for their risk of developing ADHD. This is shown by new research results from iPSYCH. A team of researchers from Aarhus University has studied how green space around the residence affects the risk of children and adolescents being diagnosed with ADHD. And the researchers find an association. "Our findings show that children who have been exposed to less green surroundings in their residential area in early childhood, which we define as lasting up until age five, have an increased risk of receiving an ADHD diagnosis when compared to children who have been surrounded by the highest level of green space," says Malene Thygesen, who is one of the researchers behind the study.
