Clinical Trial Summary

Alzheimer's disease (AD) is a neurodegenerative disease leading to one of the most common forms of dementia in humans and memory disorder is one of the first symptoms that lead to diagnosis.

Description:

Present in greater amounts in the regions of the hippocampus and cortex, the Brain-derived neurotrophic factor (BDNF) is essential to both learning and memory processes. This protein is found in lower amounts in people with AD. Acute physical activity of moderate to vigorous intensity would increase the levels of plasma BDNF whether for a healthy person or a person with AD. Nevertheless in rest, healthy people have higher level of BDNF than individuals with AD. There are no studies on the effect of chronic exercise based on BDNF level at rest in people with AD. In a hypothetical endurance training of 18 sessions, whether interval or continuous training the levels of BDNF would increase in people with AD at rest. Their physiological and neuropsychological performances would also show a rise.

Intervention

Device:
• Endurance Training
40 people will submitted to endurance training: 20 will perform a continuous training and 20 will perform an interval training. The variables that will be analyzed are maximum aerobic power, endurance, heart rate, prehension strength, Mini-Mental State Examination (MMSE), REY's test, biological examination and level of BDNF plasma, before and after the intervention and one month after the end of the intervention and one month after the end of the intervention.

Other:
• therapeutic education meetings
Group of 20 people will be the control group and will not perform ET. However, they will have 9 therapeutic education meetings.
