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 faBMC psychiatryRepetitive negative thinking is associated with subjective cognitive decline in older adults: a cross-sectional study.PMC7547434002AS-SF-15b-002Whitfield TWirth MMarchant NLSchlosser MDemnitz-King HfalseRepetitive negative thinking is associated with subjective cognitive decline in older adults: a cross-sectional study.<h4>Background</h4>In the absence of a cure or effective treatment for dementia, attention has shifted towards identifying risk factors for prevention.
