About this study
The proposed study aims to explore brain mechanisms mediating the cognitive benefits of aerobic exercise in patients with mild cognitive impairment- a prodromal stage of Alzheimer disease. We will perform FMRI experiments, as well as laboratory and behavioral tests that will advance our knowledge about the nature of these mechanisms. Participants will participate in individual- tailored aerobic training program. Pre and post evaluation will identify brain changes following the training using advanced techniques of brain imaging. Cognitive performance will be assessed prior and at the end of the program, as well as endocrine markers reflecting improvement in learning abilities. Moreover, demonstrating cortical plasticity in subjects with aMCI has tremendous practical significance for these subjects .
Read the detailed description
Mild cognitive impairment (MCI), a prodromal stage of Alzheimer disease (AD), refers to a transitional state between the cognition of normal aging and dementia such AD. To date, therapeutic approaches to AD are symptomatic and of modest efficacy. Nontheless, recent studies in animal models or healthy subjects, have shown that aerobic exercise affect brain plasticity. The current proposal aims at exploring the brain mechanisms mediating the cognitive benefits of aerobic exercise in patients with amnestic MCI (aMCI),in compare to a control group of subjects with aMCI receiving stretching exercise. More specifically, we aim to perform two fMRI experiments, that will advance our knowledge about the nature of mechanism of the cognitive benefit resulting of aerobic exercise. Our preleminary results suggest that subjects with aMCI show different hierarchy of reliable responses when processing long time scales in auditory task. Therefore, in the first experiment, we will evaluate how these patterns of temporal hierarchy of language processing are affected by aerobic exercise. Next, we will explore whether aerobic exercise affect memory enocoding task, which rely on areas in the medial temporal lobe who bear a heavy neuropathological burden in MCI. The insights gained from the study may have important clinical implications for patients who are at the early stages of Alzheimer's disease

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
physical trainingOther
Participants in both the aerobic and stretching groups will carry out their activity routines 3 d/wk for 45 to 60 minutes per session for 4 months. Training will be on "one on one" basis, where each participant will be supervised by an experienced trainer at the participant's home.Aerobic intervention protocol: subjects will practice with stationary bicycle. Exercise intensity will be monitored through wireless HR monitor. Participants will be also monitored for the intensity of their workouts by the Borg's Rating of Perceived Exertion and the "talk" test (a subjective method for estimating of appropriate cardiorespiratory exercise intensity).
Stretching exercise protocol: Participants in the stretching control group will carry out a prescribed routine of stretching and balance exercises.

How can a doctor refer a patient or contact the research team?
Contact Talma Hendler, MD (97236973953, hendlert@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
functional Magnetic Resonance Imaging (time frame: two weeks prior to intervention). It is what the study was designed to measure, not a finding.

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Apr 2014.
