About this study

Official title: Combined Aerobic Exercise and Cognitive Training for Alzheimer's Disease Prevention in At-Risk Seniors Estimated by An Exosomal Synaptic Protein Model: Cognition and Exosomal Synaptic Proteins Effects

The study aims to investigate the effect of a long-term combined aerobic exercise and cognitive training program on cognitive function and blood exosomal synaptic protein levels in seniors at increased risk for Alzheimer's Disease.

Read the detailed description

Alzheimer's disease (AD) is the most common cause of dementia in people older than 65 years worldwide. The neuropathological changes of AD occur decades before the onset of cognitive impairment, suggesting that early identification and timely intervention may postpone the clinical progress. In addition to its characteristic amyloid β and tau pathology, AD is also marked by synaptic dysfunction. Abnormal synaptic protein levels, such as growth associated protein 43 (GAP43), neurogranin, synaptotagmins, and synaptosome associated protein 25 (SNAP25) have been observed in the brain tissue and cerebrospinal fluid (CSF). Blood neuro-exosomal synaptic proteins have emerged as promising predictors for AD and cognitive decline. Particularly, the investigators previously reported a combination of blood neuro-exosomal protein (GAP43, neurogranin, SNAP25, and synaptotagmin 1) can predict AD 5 to 7 years before the clinical onset.

Both physical exercise and cognitive training have been demonstrated to improve cognitive function in AD and to exert a protective effect against developing dementia in the normal aging population. Furthermore, cognitive stimulation is an established modulator of synaptic plasticity and physical exercise might regulate synapse functional and structural change. However, whether cognitive training and physical exercise can alter exosomal synaptic protein levels and the relationship of biomarker changes to cognitive function in those seniors at increased risk for AD remain unclear.

In this study, the investigators aim to

  1. assess the effects of a long-term combined aerobic exercise and cognitive training program on cognitive function and the predictive biomarkers (blood neuro-exosomal synaptic proteins: GAP43, neurogranin, SNAP25, and synaptotagmin 1) in seniors at increased risk of AD with abnormally decreased levels of the biomarkers.
  2. determine the relationship of biomarker changes with cognitive function in these people.
  3. confirm the predictive value of the blood neuro-exosomal synaptic proteins for AD in a longitudinal setting.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in cognitive function over time as assessed by the Montreal Cognitive Assessment (MoCA)

    MoCA will be performed to evaluate the cognition of participants at the enrollment and year 1, year 3, year 5, year 7. The score ranges from 0 to 30, with higher values indicating better cognition.

    Measured: baseline time, year 1, year 3, year 5, year 7

  2. Change in cognitive function over time as assessed by Mini Mental State Examination (MMSE)

    MMSE will be performed to evaluate the cognition of participants at the enrollment and year 1, year 3, year 5, year 7. The score ranges from 0 to 30, with higher values indicating better cognition.

    Measured: baseline time, year 1, year 3, year 5, year 7

  3. Change in cognitive function over time as assessed by Clinical Dementia Rating (CDR)

    CDR will be performed to evaluate the cognition of participants at the enrollment and year 1, year 3, year 5, year 7. The score ranges from 0 to 18, with higher values indicating worse cognition.

    Measured: baseline time, year 1, year 3, year 5, year 7

  4. Change in cognitive function over time as assessed by Verbal Fluency Test

    Verbal Fluency Test will be performed to evaluate the semantic memory function of participants at the enrollment and year 1, year 3, year 5, year 7. Participants are asked to produce as many animals as possible within 1 minute. The score is the number of animals, with higher scores indicating better cognition.

    Measured: baseline time, year 1, year 3, year 5, year 7

  5. Change in cognitive function over time as assessed by Digit Span Test-Forward and Backward

    Digit Span Tests will be performed to evaluate the working memory of participants at the enrollment and year 1, year 3, year 5, year 7. The total scores are twelve for each test, with higher values indicating better cognition.

    Measured: baseline time, year 1, year 3, year 5, year 7

  6. Change in cognitive function over time as assessed by Trail-Making Test Parts A and B (TMT-A and TMT-B)

    TMT-A and TMT-B will be performed to evaluate the executive function of participants at the enrollment and year 1, year 3, year 5, year 7. Scoring is based on time taken to complete the test (e.g., 35 seconds yielding a score of 35), with lower scores indicating better cognition.

    Measured: baseline time, year 1, year 3, year 5, year 7

  7. Change in cognitive function over time as assessed by Boston Naming Test (BNT)

    BNT will be performed to evaluate the language function of participants at the enrollment and year 1, year 3, year 5, year 7. The score ranges from 0 to 30, with higher values indicating better cognition.

    ROCF will be performed to evaluate the visuospatial function and other cognition domains of participants at the enrollment and year 1, year 3, year 5, year 7. Participants are asked to produce a complicated line drawing, with higher scores indicating better cognition.

    Measured: baseline time, year 1, year 3, year 5, year 7

  9. Change in cognitive function over time as assessed by California Verbal Learning Test (CVLT)

    CVLT will be performed to evaluate the memory function of participants at the enrollment and year 1, year 3, year 5, year 7. Participants are asked to finish immediate recall, delayed recall, and delayed recognition tasks in the test, with higher scores indicating better cognition.

    Measured: baseline time, year 1, year 3, year 5, year 7

Secondary outcomes (5)

  5. The area under curve of the blood neuro-exosomal synaptic proteins (GAP43, neurogranin, SNAP25, and synaptotagmin1) for the accurate diagnosis of AD

    The area under curve is used to show the ability of the blood neuro-exosomal synaptic proteins (GAP43, neurogranin, SNAP25, and synaptotagmin1) to diagnose AD. The value of area under curve is higher, then the ability of the blood neuro-exosomal synaptic proteins to diagnose AD is stronger.
