NCT02353884

Brief Summary

The purpose of this study is to find the characteristics of mild cognitive impairment (MCI) using technology of Multi-Modality MRI , including structural MRI, functional MRI and diffusion tensor imaging(DTI). Then analyze the difference between progressive MCI (MCIp) and stable MCI (MCIs) and further construct the predictable classifier from MCI to Alzheimer's disease (AD) based on Multi-Modality MRI characteristics of MCI patients.

Outcome Measures

Primary Outcomes (1)

  • the accuracy of a predictable classifier from MCI to AD based on Multi-Modality MRI characteristics of MCI patients.

    one-hundred MCI subjects and 50 healthy controls recruited underwent structure,resting-state functional magnetic resonance imaging and diffusion tensor imaging.After 2-year follow-up,the MCI subjects were divided into progressive MCI(MCIp) and stable MCI(MCIs).Based on differences among MCIp,MCIs and healthy controls in baseline neuroimaging data,some suitable indicators were selected,and then a predictable classifier from MCI to AD based on multi-modality MRI was constructed.At last,the leave-one-out cross validation analysis were conducted to estimate the accuracy of the classifier.The classification accuracy was measured by the proportion of MCI subjects that were correctly classified into the MCIp or MCIs groups

Sampling MethodProbability Sample
Study Population

The cognition of MCI is between healthy control and AD, which is thought the transitional stage of AD. Patients with MCI have heavy risk to convert to AD.

You may qualify if:

  • Age is between 55 to 75 years old
  • Memory loss complaint and confirmed by an informant
  • Cognitive impairment in single or multiple domains, adjusted for age and education
  • Normal or near-normal performance on general cognitive function and no or minimum impairment of daily life activities
  • A Clinical Dementia Rating (CDR) score is 0.5 and consistent with the boundary of neuropsychological scale
  • Failure to meet the criteria for dementia
  • Must be able to accept examination of MRI, sight and hearing allow to complete test
  • Right handedness

You may not qualify if:

  • Other diseases that cause cognitive impairment, such as thyroid disease, stroke and so on
  • People who have severe visual and hearing impairment
