Atrophy of specific amygdala subfields in subjects converting to mild cognitive impairment.

Introduction: Accumulating evidence indicates that the amygdala exhibits early signs of Alzheimer's disease (AD) pathology. However, it is still unknown whether the atrophy of distinct subfields of the amygdala also participates in the transition from healthy cognition to mild cognitive impairment (MCI).

Methods: Our sample was derived from the AD Neuroimaging Initiative 3 and consisted of 97 cognitively healthy (HC) individuals, sorted into two groups based on their clinical follow-up: 75 who remained stable (s-HC) and 22 who converted to MCI within 48 months (c-HC).

Environmental mastery and purpose of life during COVID-19-related lockdown: A study deepening the role of personal and community resilience.

COVID-19 outbreak and the measures needed to contain its first wave of contagion produced broad changes in citizens' daily lives, routines, and social opportunities, putting their environmental mastery and purpose of life at risk. However, these measures produced different impacts across citizens and communities. Building on this, the present study addresses citizens' understanding of the rationale for COVID-19-related protective measures and their perception of their own and their community's resilience as protective dimensions to unravel the selective effect of nationwide lockdown orders.

The selective effect of lockdown experience on citizens' perspectives: A multilevel, multiple informant approach to personal and community resilience during COVID-19 pandemic.

In the face of the first wave of COVID-19 contagion, citizens all over the world experienced concerns for their safety and health, as well as prolonged lockdowns - which brought about limitations but also unforeseen opportunities for personal growth. Broad variability in these psychological responses to such unprecedented experiences emerged. This study addresses this variability by investigating the role of personal and community resilience.

Prosocial behaviours under collective quarantine conditions. A latent class analysis study during the 2020 COVID-19 lockdown in Italy.

We aimed to identify the patterns of prosocial behaviours under collective quarantine conditions. Survey data were collected from a sample of Italian adults during the March May 2020 COVID-19 lockdown in Italy. Participants reported on offline and online prosocial behaviours, sense of community responsibility (SoC-R) and perceptions of community resilience.
