Arms of the Study

Arm 1

Arm 2

Arm Type

No Intervention

Experimental

Arm Label

Control group

Physical exercise

Arm Description

No intervention

A 3-month walking program (3 times a week for 12 weeks) on treadmill supervised by a physiotherapist. Duration of the exercise is progressively increased from 15 min to 45 min over a 6-week period and the intensity of the exercise is moderate (a 12-13 score on Borg scale).

Outcomes

Primary Outcome Measures

Brain Glucose Consumption
Brain glucose uptake (umol/100g/min) using 18F-FDG PET imaging
Brain Acetoacetate Consumption
Brain acetoacetate uptake (umol/100g/min) using 11C-AcAc PET imaging

5. Study Description

Brief Summary
The aim of this study is to evaluate the effect of a 3-month walking program on brain energy metabolism in patient with mild Alzheimer's disease (AD). Two groups of sedentary patients with mild AD are followed and compared over a 3-month period of time: Control (non-active) and walking (from 15 to 45 minutes of exercise on a treadmill, 3 times a week for 12 weeks) groups. All the participants are evaluated on their cognition, brain volumes (MRI) and brain fuel consumption (PET scan with 18-FDG and 11C-AcAc) at the beginning and at the end of the study.
