Aerobic Exercise Training in Mild Cognitive Impairment Study

Completed · Not applicable

Conditions studied: Mild Cognitive Impairment

In brief

This study is being done to find out whether regulation of brain blood flow is altered in patents with mild cognitive impairment (those who have memory problems but otherwise healthy) when compared with healthy elderly individuals. In addition, this study will determine whether exercise training improves brain blood flow, brain structure, and brain function in patients with mild cognitive impairment (MCI). This is a research study because at present the investigators know little about brain blood flow regulation in patients with mild cognitive impairment. The investigators also know little about whether exercise training improves brain blood flow, brain structure, and brain function in patients with mild cognitive impairment.
