Summary
Black adults have higher odds of mild cognitive impairment (MCI) due to factors like diabetes and stroke. Identifying and addressing these modifiable risk factors is crucial for reducing health disparities.
Area of Science:
- Gerontology
- Neuroscience
- Public Health
Background:
- Mild cognitive impairment (MCI) poses a significant public health challenge, disproportionately affecting certain ethnoracial groups.
- Understanding modifiable risk factors for MCI is essential for reducing health inequities.
Purpose of the Study:
- To investigate potential risk factors associated with MCI in adults aged 65 and older.
- To compare the prevalence of these risk factors between Black and White participants.
- To explore the interplay between race, MCI, and various exposures.
Main Methods:
- Cross-sectional study of 2845 adults aged 65+ years.
- Evaluated exposures including education, health, lifestyle, and sensory function.
- Used logistic regression to model MCI risk, adjusting for covariates and examining race*exposure interactions.
Main Results:
- Black participants exhibited 53% higher odds of MCI compared to White participants, even after adjusting for age, sex, and education.
- Depressive symptoms, diabetes, stroke, lifetime smoking, sleep disturbances, social isolation, loneliness, anxiety, and sensory impairments were associated with increased MCI odds.
- No significant interactions were found between race and specific exposures.
Conclusions:
- Black individuals face a higher risk of MCI, linked to specific health and lifestyle factors.
- The identified risk factors for MCI were consistent across both Black and White participants.
- Targeting modifiable risk factors may help mitigate MCI burden and reduce health disparities.

01:27Ethnic Identity within a Larger Culture
30
Adolescents from ethnic minority backgrounds face a multifaceted journey in forming their identities, shaped by the intersections of cultural expectations and personal exploration. For these adolescents, identity formation involves not only typical developmental challenges but also navigating the perceptions and attitudes of the majority culture. As they grow, adolescents in ethnic minority groups often become increasingly aware of stereotypes, social biases, and discrimination, all of which...

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

01:30Cognitive Development During Adulthood
94
Cognitive development continues throughout adulthood, undergoing significant shifts across early, middle, and late stages. Individual transition occurs from adolescent idealism to pragmatic and adaptable thinking in early adulthood. During this period, individuals learn to integrate personal beliefs with the recognition that other perspectives are equally valid. Exposure to the complexities of modern society, diverse experiences, and higher education contribute to this adaptive thought process,...

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...

01:27Language and Cognition

Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.

01:30Negative and Cognitive Symptoms of Schizophrenia

Negative symptoms of schizophrenia indicate a reduction or absence of typical behaviors and emotional responses found in healthy individuals, while positive symptoms reflect an excess or distortion of normal functioning.
Negative Symptoms
Negative symptoms of schizophrenia manifest as deficits in normal emotional and behavioral functioning, profoundly impacting daily life. Individuals with schizophrenia often display a flat affect, characterized by a near-total absence of emotional expression,...
