Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The mSIM study involves developing and conducting feasibility testing of a web-based application that will deliver mobile-based simultaneous exercise and memory skills training program (mSIM) for amnesic Mild Cognitive Impairment (aMCI) patients.

The randomized control trial (RCT) will evaluate the efficacy of mSIM on memory performance and everyday functioning using 2 study arms (Group 1 activity monitoring control (via Fitbit) (CON) vs Group 2 mSIM intervention plus activity monitoring via Fitbit). mSIM treatment response will be evaluated using neuropsychological and functional evaluation. Concentration levels of peripheral biomarkers Brain-derived neurotrophic factor (BDNF) and norepinephrine (NE) also be assessed.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The purpose of the study is to create a web-based cognitive compensatory, and predominately memory skills, training course that is delivered on a mobile device and compatible with use on a stationary bicycle and test its efficacy on memory and functional ability.

Participants will be recruited from (1) the Pacific Brain Health Center in Santa Monica, which is a high-volume memory-care and dementia outpatient clinic within a large physician medical group affiliated with Providence Saint John's Health Center, (2) advertisement to participants in the local community, and (3) establishment of a website landing page that permits interested individuals to contact the trial coordinator. Up to five participants will be course beta testers. They will receive a truncated version of the course and will provide detailed feedback. 30 participants will be randomized into one of two groups. Group 1 (control arm) will have their physical activity levels continuously monitored (via Fitbit). Participants will receive the Experimental Research Subject's Bill of Rights prior to signing the informed consent form (ICF), authorization of use and disclosure of protected health information (PHI), and authorization of medical record release for the subject's treating physician, will be obtained from each participant prior to enrolling in the study. A copy of all signed ICF's will be given to the participants, and the investigator will retain the original.

Group 2 (active arm) will receive the mSIM intervention plus activity monitoring (via Fitbit). Group 2 will first undergo 2-6 week of an exercise ramp-up (2x/week) until they can sustain 40 minutes at 50% heart rate reserve (HRR). The intensity for mSIM training will be 40-60% HRR. After the ramp-up phase the mSIM participants will begin the 12-week intervention, comprised of 2 60-minute sessions/week. mSIM treatment response will be evaluated using neuropsychological and functional evaluation. Assessments will occur at baseline, mid-trial (3-4 months) and post-trial (5-6 months). Concentration levels of peripheral biomarkers BDNF and NE at baseline and post-trial (5-6 months) will also be assessed.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

The study will include two arms: Arm 1: activity monitoring only control (CON), Arm 2: active intervention with mSIM program (mSIM) plus activity monitoring (via Fitbit), to evaluate the efficacy of the mSIM intervention on memory performance and everyday functioning. The 'Activity monitoring only' arm will serve as the control group. Study objectives include measuring treatment related changes in memory performance and everyday functioning along with putative biomarkers of the behavioral changes.

* Subject must have adequate motor capacity to use a mobile phone/iPad/computer as indicated by self-report.
* Subjects must be able to provide medical clearance to participate in an unsupervised, moderate intensity exercise program from a physician.

Exclusion Criteria

* Subjects must not have an existing diagnosis of a neurodegenerative disorder (e.g., Alzheimer's Disease, Lewy Body Dementia, Frontal-Temporal Dementia).
* Subjects must not have a prior diagnosis that might impact cognition and movement abilities including: significant cardiovascular disease, significant respiratory disease, illness or injury, substance abuse, schizophrenia, bipolar disorder, or other neurological diseases.
* Subjects must not have a previous Mini Mental State Exam (MMSE) score below 19.
* Subjects must not have a previous Clinical Dementia Rating (CDR) global score of ≥2.
* Subjects must not have a Montreal Cognitive Assessment (MoCA)43 score of below 18 previously or during their screening evaluation.
* Subjects must not demonstrate a progression of aMCI to dementia at screening based on the best judgement of a study Clinical Neuropsychologist.
* Subjects must not currently participate in a high level of physical activity prior to study start as assessed by the International Physical Activity Questionnaire (IPAQ) at screening.
* Subjects must not endorse that they are unable to participate in moderate intensity aerobic activities, such as fast walking or passing/kicking a ball to a partner at screening.
