The impact of different types of early interpersonal trauma on biological aging, neurophysiological activity, and psychological functioning in young adults.

A large body of research has provided strong evidence of the detrimental effects of early interpersonal trauma (EIT) on socio-emotional, behavioral, cognitive, and physical domains of the individual’s functioning. Nevertheless, the mechanisms elicited by the exposure to different types of EIT as well as their impact on neurodevelopmental trajectories have yet to be fully elucidated. To fll this gap, we investigated biological aging, neurophysiological activity, and psychological functioning in young adults who were previously classifed according to the type of EIT. In these groups, salive telomere length (TL) was acquired (as a measure of biological age) and resting high-density electroencephalography (hdEEG) was recorded (as a measure of resting-state neurophysiological activity). Clinical scales evaluating the quality of a!achment bonding, a#ect regulation, and psychopathology were also administered. Analyses showed interesting differences between the groups in terms of TL, neurophysiological features of resting hdEEG, as well as clinical measures. Such fndings may enrich the knowledge about the modulatory role of different types of EIT on the individual’s psycho-neurobiological functioning in young adults.
