Stereotypes, Prejudice, and Discrimination

Stereotypes, Prejudice, and Discrimination

Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who...

Summary

This summary is machine-generated.

Racial and ethnic differences in frontotemporal dementia (FTD) neuropsychological testing were observed, with minoritized groups scoring lower. These disparities significantly decreased when accounting for factors like disease severity and education.

Background:

Frontotemporal degeneration (FTD) research understudies racial/ethnic differences in neuropsychological testing.
Understanding these differences is crucial for improving care for diverse FTD patient populations.

Purpose of the Study:

To evaluate racial and/or ethnic differences in cognitive test performance among FTD patients.
To assess the likelihood of impairment status in relation to race/ethnicity.

Main Methods:

Compared cognitive scores and impairment likelihood between Black, Hispanic, and White participants.
Utilized data from the National Alzheimer's Coordinating Center dataset.

Main Results:

Minoritized individuals showed lower scores and higher impairment likelihood in lexical retrieval, processing speed, cognitive flexibility, and working memory.
Differences were attenuated when controlling for disease severity, age, sex, education, and vascular comorbidities.

Conclusions:

Racial/ethnic disparities in FTD neuropsychological tests are significantly reduced by considering factors like disease severity and education.
Future FTD research must enhance representative participation and address social determinants of health to mitigate these differences.
