Profiles in Melancholy, Resilience: Abused kids react to genetics, adult support

Parental neglect and abuse leave many children feeling hopeless and despondent. Yet some youngsters weather such maltreatment remarkably well. In a new study, scientists offer a rare peek at how genetics and interactions with adults collaborate either to depress mood or to foster resilience in abused kids.

Maltreated children who inherit two copies of a gene variant that was previously recognized to weaken the brain’s mood regulation exhibit a marked propensity to become depressed only if they don’t have a positive relationship with at least one adult, concludes a team led by psychiatrist Joan Kaufman of Yale University School of Medicine.
