In a cross-sectional survey of 10,797 community-dwelling older adults in China's Yangtze River Delta, stigma was the factor most strongly associated with lower dementia screening intention, while perceived benefits ranked second and emerged as the network's central hub. The 2025 study found perceived benefits were positively linked to screening-related health literacy and approval from significant others, and negatively linked to stigma.

Why It Matters To Your Practice

• Dementia screening uptake depends on more than access: modifiable psychosocial factors may strongly shape whether older adults intend to be screened.

• For clinicians using or considering AI-enabled risk assessment or screening workflows, patient acceptance may hinge on how clearly benefits are communicated and how stigma is addressed.

• The findings are especially relevant in community and primary care settings serving older adults, where screening conversations often begin.

Clinical Implications

• When discussing dementia screening, emphasize practical benefits such as earlier planning, symptom evaluation, caregiver support, and access to services.

• Screen for stigma during routine conversations; fear, shame, or fatalism may be bigger barriers than logistics alone.

• AI tools that identify high-risk patients may improve workflow, but they will not by themselves increase screening uptake if patients do not perceive value.

• Consider involving family or trusted others when appropriate, since approval from significant others was positively connected to perceived benefits.

Insights

• Researchers surveyed older adults from Shanghai and Jiangsu, Zhejiang, and Anhui provinces between April and October 2025.

• Multiple machine-learning models were compared, with XGBoost showing comparatively strong performance and generalizability.

• SHAP analysis ranked stigma as the top factor associated with screening intention, followed by perceived benefits.

• Network analysis suggested perceived family burden may reinforce stigma, pointing to another target for counseling and education.

The Bottom Line

• If AI expands dementia screening in practice, clinician communication will still matter: reducing stigma and increasing perceived benefits may be key to converting risk identification into actual screening intent.
