NCT07128186

Brief Summary

The objective of this observational study is to evaluate the accuracy and feasibility of an artificial intelligence-based multimodal cognitive screening system in early identification of diabetes-related mild cognitive impairment (MCI) among type 2 diabetes mellitus (T2DM) patients through a 3-5 year follow-up. It also aims to analyze the correlation between diabetic metabolic indicators (such as glycemic variability and HbA1c levels) and cognitive function changes, thereby determining the value of this intelligent screening system in early detection and intervention of cognitive impairment in T2DM patients, which constitutes the key focus of this research.

Outcome Measures

Primary Outcomes (2)

  • Early Identification Accuracy of the AI System

    Sensitivity, specificity, and area under the ROC curve (AUC) of the AI system in detecting Mild Cognitive Impairment (MCI), compared with traditional scales (MMSE/MoCA).

    From enrollment to the end of follow-up for 3-5 years

  • Cognitive Deterioration Rate

    Conversion rates from:Cognitively Normal (CN) → MCI; MCI → Alzheimer's Disease (AD)

    From enrollment to the end of follow-up for 3-5 years

Secondary Outcomes (2)

  • Association Between Diabetic Metabolic Indicators and Cognitive Decline

    From enrollment to the end of follow-up for 3-5 years

  • Predictive Value of Multimodal Data

    From enrollment to the end of follow-up for 3-5 years

Study Arms (2)

Cognitive Normal Group

Healthy control group without significant cognitive impairment in the study

Other: follow-up observation

Mild Cognitive Impairment Group

An intermediate state with subjective or objective cognitive decline (e.g., memory, executive function) that does not meet the diagnostic criteria for dementia

Other: follow-up observation

Interventions

In this study, no additional interventions were administered to any enrolled participants; only 3-5 years of follow-up observation were conducted, with cognitive status data collected at both baseline and endpoint.

Study Population

This study will enroll 5,000 eligible participants from 20 participating centers across Hubei Province for a 3- to 5-year longitudinal follow-up, with strict adherence to the predefined inclusion/exclusion criteria.

You may qualify if:

  • Diagnosed with type 2 diabetes mellitus (T2DM).
  • Aged 40-75 years, with self-reported or informant-reported memory complaints.
  • Cognitive assessment scores consistent with either:
  • Cognitive Normal (CN) or
  • Mild Cognitive Impairment (MCI).
  • Preserved ability to perform basic activities of daily living (ADLs).
  • Memory-specific deficits only (e.g., partial forgetfulness), with intact other cognitive domains (e.g., reasoning, judgment, attention, and executive function).

You may not qualify if:

  • Other types of diabetes (e.g., type 1 diabetes, gestational diabetes).
  • Education level \<6 years.
  • Metabolic disorders that may affect cognition, including:
  • Acute carbohydrate metabolism events within 3 months (e.g., severe hypoglycemia, diabetic ketoacidosis, hyperglycemic hyperosmolar state).
  • Hypothyroidism or other endocrine disorders.
  • Neurological/psychiatric conditions that may impair cognition:
  • History of head trauma, depression, anxiety, delirium, severe pulmonary/renal disease, heart failure, or malignancy.
  • Substance abuse (past 2 years), including nicotine/alcohol dependence.
  • Recent medication use (within 1 month):
  • Anti-Parkinsonian drugs, antiepileptics, sedatives/hypnotics.
  • Cognitive-enhancing drugs (e.g., donepezil, memantine).
  • Inability to complete AI screening or follow-up due to:
  • Speech/hearing/visual impairments or other disabilities
