the effectiveness of dual task training in elderly with cognitive decline

Conditions: Mild Cognitive Impairment

Summary: cognitive decline is the impairment of memory, execution, or language. early detection of the individuals who manifest cognitive decline and provide appropriate interventions may help reduce the burden of their caregivers and the medical expenses of the health-care system. many studies have found that dual-task training combining cognitive training and exercise can improve cognitive function in older adults. however, it is yet not clear the appropriate frequency of the effective dual-task training for elderly with cognitive decline. thus, this study aims to compare the intervention effects of high frequency sequential and low frequency dual-task training for elderly with cognitive decline.
