IT STARTS AT BIRTH –
March 15, 2022 – “This study suggests to me that binge eating disorder is wired in the brain, even from a very, very early age,” Murray said. “The question that we don’t know, which is something that we will address in time, is whether successful treatment of binge eating disorder in kids helps correct brain development. The prognosis of almost all psychiatric diseases is better if you can treat them in childhood.”
For this study, Murray and his colleagues analyzed brain scans and other data from 71 children with diagnosed binge eating disorder and 74 children without binge eating disorder, who are part of a large longitudinal study called the Adolescent Brain and Cognitive Development Study. That study includes data of 11,875 children ages 9-10 who were enrolled in 2016-2018 and recruited from 21 sites around the U.S.
In the children with binge eating disorder, they saw elevations in gray matter density in areas that are typically “pruned” during healthy brain development. Synaptic pruning, a development phase that occurs between ages 2 and 10, eliminates synapses that are no longer used, making the brain more efficient. Disturbed synaptic pruning is linked to a number of psychiatric disorders.
