新出现的证据表明,在少数族裔人群中,性功能障碍和性别差异可能会增加患阿尔茨海默氏症的风险。
疾病和痴呆症相关疾病(ADRD)。这一举措可能不会到期,至少在一定程度上是为了减少少数群体的累积社会影响。
压力;;与社会心理隔离和孤独有关;;心理障碍和心理障碍阻碍了他们的护理和服务。社会心理支持,等等。
另一方面,在少数族裔面临压力的情况下,它也已经成为一个保护性的因素,它是一个成功的潜在预测因素。
认知老龄化在中国普通老年人中存在。然而,很少有研究对社交网络的社会支持进行评估。
对性障碍和非性别的少数族裔进行了详细的研究,以进一步确定促进认知能力的具体因素和特征。

这一事件的风险来自于ADRD。我们可以预计,在中国的社交网络体系中,有更多的理解和差异,也有更多的相似之处。
少数人和大多数成年人的这些特征与他们的关系密切相关,这与他们的压力和衰老相关的认知有关。
这将使我们能够更好地识别与认知能力、储备能力和弹性相关的可修改的因素,并为未来提供信息。
干预措施旨在防止认知能力下降和ADRD。
英文摘要
7. PROJECT SUMMARY/ABSTRACT
Emerging evidence suggests that sexual and gender minority populations are at increased risk for Alzheimer’s
disease and related dementias (ADRD). This may be due, at least in part, to the cumulative impact of minority
stress;; related social isolation and loneliness;; and barriers to care and support services. Social support, on the
other hand, has emerged as a protective factor in the face of minority stress, and as a predictor of successful
cognitive aging among the general population. However, few studies have assessed the social support networks
of sexual and gender minorities in detail to determine the specific support characteristics that facilitate cognitive
reserve and resilience. The proposed study will fill this gap by comparing the stress, social support networks,
and aging-related cognition of a newly recruited sample of sexual and gender minority adults (n = 300, age 25-
85) to those of a matched heterosexual, cisgender sample (n = 300) enrolled in an ongoing longitudinal study of
aging and cognitive reserve (the Reference Ability Neural Networks or RANN study). In addition, the proposed
study will conduct secondary analysis of MRI data collected in RANN to explore differences in brain features
between minority and majority groups, generating hypotheses for future research. The specific aims are: (1) To
compare stress (perceived general stress and minority stress related to one or more marginalized identities) and
cognitive performance across multiple domains in newly recruited sexual / gender minority adults and matched
heterosexual, cisgender adults enrolled in the RANN study;; (2) To compare social network characteristics of
sexual / gender minority adults to those of matched heterosexual, cisgender adults, and examine within- and
between-group differences in social support based on sexual orientation, gender identity, and age;; (3) Across
both identity groups (N = 600), to examine the role of minority stress, social support, resources and wellbeing in
development of cognitive reserve and resilience (i.e., how these assets moderate the effects of minority stress
and aging on health and cognitive functioning);; and (4) In an exploratory analysis, to evaluate differences
between sexual / gender minority (n > 40) and matched heterosexual, cisgender RANN participants in MRI-
measured brain features and their relation to stress, social network characteristics, cognitive functioning, and
risk for incident ADRD. We expect that understanding differences and similarities in the social networks of
minority and majority adults and the relationship of these characteristics to stress and aging-related cognition
will enable us to identify modifiable factors associated with cognitive reserve and resilience, informing future
interventions to prevent cognitive decline and ADRD.
