Summary

Background: Current treatment for Alzheimer's disease (AD) is symptomatic and can only temporarily slow down progression.

Exercise has the potential to improve cognition, psychological symptoms, physical performance and quality of life, but evidence is scarce. Previous trials are short, often underpowered and involving home based light exercise programs. Most have included nursing homes residents with severe or undefined dementia. The aim of the ADEX trial is to establish whether exercise is effective in improving cognition, physical performance and quality of life as well as reducing the prevalence of psychological symptoms among AD patients.

Methods: The ADEX Trial is a multicentre, single-blind, randomized clinical trial. Based on power calculations the investigators plan to recruit 192 home-dwelling patients aged 50-90 years with mild to moderate AD. The participants will be randomly allocated into two groups: An intervention group attending 16 weeks of continuously supervised moderate aerobic exercise 1 hour three times a week and a control group only receiving usual care. The hypothesis is that aerobic exercise will improve physical function, the cognitive and daily functioning and quality of life in people with mild to moderate AS.

Blood sampling will be performed in all subjects to examine effects on biomarkers. A subgroup of the patients will also undergo MRI, PiB-PET and lumbar puncture to investigate structural changes and β-amyloid accumulation.

Further, a health-economic analysis will be performed.

Recruitment was started in January 2012. Last study visits are planned to be performed in January 2014 and results will be available in 2014. This RCT will contribute to evidence regarding the potential effects of a systematic program of physical exercise for patients with Alzheimer's disease.

Conditions

  • Alzheimer Disease

Interventions

OTHER

Aerobic exercise

Physical exercise in the intervention group will be delivered as an individually tailored program consisting of 4 weeks of adaptation exercise followed by 12 weeks of continuously supervised moderate aerobic exercise 1 hour three times a week. The participants can choose from treadmill, stationary bike and crosstrainer.
