“…By altering salience network connectivity, early Aβ pathology may make older adults more sensitive to affective information. While increased emotional sensitivity may yield interpersonal benefits for some people as they become more attuned and responsive to the emotions of others, it may also make them more vulnerable to negative emotional experiences including depressed mood ( Donovan et al, 2018 , Yasuno et al, 2016 ), loneliness ( Donovan et al, 2016 ), and neuroticism ( Binette et al, 2021 , Fredericks et al, 2018 , Snitz et al, 2015 , Terracciano et al, 2021 ). The Aβ+ participants in the present study did not exhibit significant depressive symptoms during the years in which empathy was assessed, however, which suggests our results were not accounted for by depressive symptoms or low mood.…”

“…Similar salience network connectivity enhancements have also been reported in asymptomatic adults at genetic risk for AD ( Machulda et al, 2011 ) and in individuals with mild cognitive impairment (MCI) ( Bai et al, 2009 ), a clinical stage that often precedes AD dementia. In addition to lower scores on tests of episodic memory ( Hedden et al, 2013 ), cognitively healthy older adults with elevated Aβ have greater increases in neuroticism ( Binette et al, 2021 , Fredericks et al, 2018 , Snitz et al, 2015 , Terracciano et al, 2021 ) as well as higher depression ( Donovan et al, 2018 , Yasuno et al, 2016 ) and loneliness ( Donovan et al, 2016 ) than their peers, affective changes that may reflect enhanced connectivity in the salience network ( Balthazar et al, 2014 , Fredericks et al, 2018 , Zhou et al, 2010 ).…”

“…Pesquisas têm evidenciado associações entre os traços de personalidade, envelhecimento saudável e longevidade, sendo que cada traço possui uma relevância particular (Pocnet, Popp, & Jopp, 2020), com destaque para C e N (Terracciano et al, 2021;Turiano et al, 2021). Igualmente, esses dois traços aparecem subjacentes a um estilo de vida composto por hábitos que aumentam a predisposição para o desenvolvimento da doença de Alzheimer, em que a configuração de elevado N e baixo C estão associados com inflamação em certas regiões do cérebro que são preditores da doença (Terracciano et al, 2021). Em conjunto, os traços C e N explicam 8% da variância na produção dessas inflamações no cérebro.…”

“…Conscienciosidade é um dos traços de personalidade mais importantes para explicar o ES, já que está diretamente associado com o engajamento em comportamentos de promoção da saúde, e com a qualidade da cognição (Terracciano et al, 2021;Pocnet et al, 2020;Turiano et al, 2021). O traço C parece influenciar o ES por meio da saúde e do bem-estar, como é o caso da faceta autodisciplina, que é associada positivamente com comportamentos saudáveis (por exemplo, alimentação saudável e prática de atividades físicas) e negativamente com comportamentos não saudáveis (uso de álcool e cigarro).…”

“…The advances in knowledge about the association between personality and neuropathology in Alzheimer’s disease (AD) is highlighted in the literature [ 1 , 2 , 3 , 4 ]. In turn, personality changes in AD have been documented in the literature and may be a useful early clinical marker [ 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 ].…”
