50/100

✓ Peer-reviewed alzhub usefulness score 50 out of 100. Mild cognitive impairment

Topic: Risk, prevention and care in population studies

The rate of reversion from MCI to normal cognition was 37.0% after 2 years and 32.9% after 12 years. The rate of progression to dementia was 18.0% after 2 years and 30.2% after 12 years. In the nomogram for reversion to normal cognition, the most significant influences were grip strength, depression, number of meetings, age, and regular exercise, with an area under the ROC curve (AUC) of .66. In contrast, in the nomogram for progression to dementia, the most significant influences were age, grip strength, instrumental activities of daily living, number of social meetings attended, depression, and regular exercise, with an AUC of .69. These nomograms can serve as an effective intervention tool for preventing dementia in the field of community health care since they can serve as a visual technique for presenting information on risk to individuals with MCI.

Key findings

The rate of reversion from MCI to normal cognition was 37.0% after 2 years and 32.9% after 12 years.

In the nomogram for reversion to normal cognition, the most significant influences were grip strength, depression, number of meetings, age, and regular exercise, with an area under the ROC curve (AUC) of .66.

Why it matters

In community-dwelling older adults with mild cognitive impairment, the rate of reversion to normal cognition was 37.0% after 2 years and 32.9% after 12 years, while progression to dementia was 18.0% after 2 years and 30.2% after 12 years. Nomograms based on factors such as grip strength, depression, social meetings, age, and regular exercise were built to present risk information, with modest accuracy.
