There is a growing realization that
early life influences have lasting
impact on brain function and structure. Recent research has demon-
strated that genetic relationships in adults can be used to parcellate the
cortex into regions of maximal shared genetic influence, and a major
hypothesis is that genetically progr
ammed neurodevel
opmental events
cause a lasting impact on the organization of the cerebral cortex
observable decades later. Here we tested how developmental and
lifespan changes in cortical thickness fit the underlying genetic organi-
zational principles of co
rtical thickness in a longitudinal sample of 974
participants between 4.1 and 88.5 y of age with a total of 1,633 scans,
including 773 scans from children below 12 y. Genetic clustering of
cortical thickness was based on an independent dataset of 406 adult
twins. Developmental and adult age-
related changes in cortical thick-
ness followed closely the genetic organization of the cerebral cortex,
with change rates varying as a functi
on of genetic similarity between
regions. Cortical regions with overlapping genetic architecture showed
correlated development
al and adult age change trajectories and vice
versa for regions with low genetic overlap. Thus, effects of genes on
regional variations in cortical thickness in middle age can be traced to
regional differences in neurodevelopmental change rates and extrap-
olated to further adult aging-related cortical thinning. This finding
suggests that genetic factors contribute to cortical changes through life
and calls for a lifespan perspective i
n research aimed at identifying the
genetic and environmental determinants of cortical development
and aging.

The internet seems promising for delivering interventions to enhance well-being in a normal population. The aim of this study was to test the effects of an internet-based positive psychology intervention targeting gratitude, pleasant activities, strengths, mastery, acts of kindness, optimism, flow, attributions, and mindfulness. One-hundred and twelve participants were randomized to the intervention and 94 to the control group, and data were collected at baseline, one, two, and six months after intervention onset. The balance of positive to negative affect increased over time among participants in the intervention group (unstandardized beta coefficient [B] = 0.07, p < 0.01), as compared to the controls (B = 0.02, p = 010). The intervention worked equally well regardless of participants’ gender, age, or education. However, optimism did not mediate the effect of the intervention on affect balance. In conclusion, the intervention had a small, but significant effect on affect balance among healthy adults.

Background: High prevalence of minor depression and low well-being constitutes both individual and societal burden. The Internet provides a promising platform for treatment delivery. Objective and Method: A randomized controlled trial was conducted to determine the efficacy of an internet-based self-help intervention Bedre Hverdag (BH) for mild-to-moderate depression and promotion of well-being. Long-term effects (i.e.6 months) of BH were assessed in comparison to a waiting-list control group. Results: Of the 206 eligible participants, 112 were randomized to the experimental group and 94 to the waiting-list control group. Data from 34 participants in the experimental group and 47 from the control group were subjected to statistical analyses. Individuals assigned to BH reported significant increases in positive affect (PA) at 1 month follow-up, as measured by Positive Affect Schedual (PANAS); z = - 2.49, p = .011, r = .42 , which were significantly different from levels of PA at the same time period in the control group, U = 589, z = -2.01 , p = .044 , r = .2. Increases in PA were no longer significant at 2 and 6 month follow-ups. No statistically significant reductions in negative affect (NA) as measured by the Negative Affect Schedual (PANAS) and depressive symptoms as measured by the Center for Epidemiologic Studies Depression scale (CES-D) were observed in the experimental group as compared to the control group. Treatment x Educational attainment interaction explained 5.3% of variance in depressive symptoms, and 10.7% of variance in NA at 1 month follow-up, above and beyond the main effects. Individuals with lowest level of educational attainment reported largest reductions in both CES-D scores and NA. Conclusion: BH produced significant increases in PA at 1 month post-treatment. No significant reductions were observed in either depressive symptoms or NA. Educational attainment moderated the intervention's effects on depressive symptoms and NA.
