Predicting cognitive impairment risk in people with type 2 diabetes

Early Diagnosis and Risk Evaluation of Mild Cognitive Impairment in Diabetes

Observational The Affiliated Nanjing Drum Tower Hospital of Nanjing University Medical School · NCT05590442

This study is trying to see if certain tests can help predict which people with type 2 diabetes might develop mild cognitive impairment as they get older.

What this trial studies

This observational study aims to develop and validate a risk model that predicts the likelihood of mild cognitive impairment in individuals diagnosed with type 2 diabetes mellitus. The study will involve cognitive assessments, including the Montreal Cognitive Assessment Scale (MoCA) and olfactory tests, to gather data on participants aged 40 to 80 years. By analyzing these assessments, researchers hope to identify key risk factors associated with cognitive decline in this population. The findings could lead to improved screening and early intervention strategies for those at risk.

Who should consider this trial

Good fit: Ideal candidates for this study are individuals aged 40 to 80 years with type 2 diabetes and MoCA scores between 19 and 30.

Not a fit: Patients with significant cognitive impairment (MMSE scores < 24) or other neurological conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance early detection and management of cognitive impairment in patients with type 2 diabetes, potentially improving their quality of life.

How similar studies have performed: Other studies have explored cognitive impairment in diabetes, but this specific risk model approach is relatively novel.
