“…Greater purpose in life has been related to higher perceived cognitive function, decreased cognitive decline, and reduced risk of mild cognitive impairment and Alzheimer’s disease [ 33 – 35 ]. A measure of meditation practice was included because recent theoretical frameworks [ 36 , 37 ] and preliminary neuroimaging data [ 38 ] highlight the potential positive impact of meditation on healthy ageing. Lastly, measures of rumination and worry, both components of RNT, were included to assess the role of time-dependent negative thoughts (i.e., past- and future-directed) in the hypothesised relationship between SCD and RNT.…”

Background In the absence of a cure or effective treatment for dementia, attention has shifted towards identifying risk factors for prevention. Subjective Cognitive Decline (SCD) describes self-perceived worsening of cognition despite unimpaired performance on neuropsychological tests. SCD has been associated with an increased dementia risk and steeper memory decline. Repetitive negative thinking (RNT) is a transdiagnostic process that manifests across several mental health disorders associated with increased vulnerability to dementia. RNT has thus been proposed as a candidate marker of risk for dementia and, relatedly, could contribute to the manifestation of SCD. We aimed to investigate the relationship between SCD and RNT alongside other proposed psychological risk/protective factors for dementia and cognitive decline. Methods In a cross-sectional online survey, 491 older adults (mean = 64.9 years, SD = 4.2; 63.1% female) completed measures of RNT, personality traits, purpose in life, worry, rumination, and meditation practice. SCD was assessed continuously via self-perceived cognitive function (Neuro-QoL) and categorically via endorsement (yes/no) of memory complaints. Regression models, using a stepwise backwards elimination, were built to assess associations between SCD, demographics, and all risk/protective factors. Results A total of 24.2% of participants reported memory complaints. In the final prediction models, RNT was the only psychological variable associated with lower self-perceived cognitive function and with a higher likelihood of memory complaints. Conclusions This study empirically corroborates the theoretical relationship between SCD and RNT. Longitudinal studies are needed to establish whether RNT is a prodromal symptom or an independent risk factor, and whether RNT can be a promising construct for future research on SCD and dementia risk.

“…The current study aimed at delineating neural markers of proficient emotional resilience and empathy in ageing, which are increasingly recognized as important protective factors against mental illness and cognitive decline in this population 71 . We assessed both reactivity and recovery of brain networks to negative socio-affective situations (i.e., during and after exposure) in a large cohort of healthy elderly, allowing us to probe for emotional carryover effects in resting state (emotional inertia) as an indicator of maladaptive regulation processes 16 , and to examine their relationship with measures of anxiety, rumination, and negative thoughts.…”

While basic emotional functions seem preserved in the elderly, adaptive brain mechanisms required to cope with socio-emotional stressful events remain unresolved and scarcely investigated in this population. To evaluate how the aging brain reacts during and after emotionally challenging social events, we designed a new "task-rest" paradigm in which elderly participants (N=127) underwent functional magnetic resonance imaging (fMRI) while exposed to socio-emotional videos. We unveil neural markers of "emotional inertia" in brain activity and connectivity following negative scenes. Exposure to others' suffering induced differential activations that lingered over time into the subsequent resting-state in regions of the default mode network (DMN). Moreover, emotional elicitation potentiated subsequent resting-state connectivity between posterior DMN and amygdala, which in turn was related to anxiety, rumination, and negative thoughts. These findings uncover brain mechanisms underlying emotional resilience and empathy in the elderly and may help understand how poor social stress regulation promotes neurodegenerative diseases.

“…Risk factors included RNT and the personality trait neuroticism (25)(26)(27). Potentially protective factors included purpose in life (28)(29)(30), meditation practice (31)(32)(33), and the conscientiousness personality trait (34,35). We further included measures of rumination and worry to assess the role of timedependent negative thoughts (i.e., past-and future-directed), and the remaining dimensions of the big five personality framework (extraversion, agreeableness, and openness to experience).…”
