A new Science study suggests variables linked to socioeconomic status—increased stress and reduced sleep—have strong relationships to brain structure and function in children. Brain differences observed are unrelated to genetic ancestry and may not be permanent. scim.ag/4opL5PF
Brain-wide associations in the Adolescent Brain Cognitive Development (ABCD) Study revealed that socioeconomic status exhibited the strongest associations with brain organization. Socioeconomic status dominated population-level variation through arousal-related patterns linked to sleep and stress, specifically norepinephrine and stimulant effect maps. Socioeconomic status models demonstrated robust generalizability across different groups, highlighting its importance as the primary variable in childhood BWAS.
