Title: SYNchronizing Exercises, Remedies in GaIt and Cognition (SYNERGIC): A Randomized Controlled Double Blind Trial
Brief Summary: The proposed SYNERGIC trial is uniquely designed to evaluate the effect of aerobic and progressive resistance training exercises, combined with cognitive training and Vitamin D3 supplementation, in cognition and mobility in older adults with Mild Cognitive Impairment (MCI).


Options:
A: Inclusion Criteria:

* aged 60-77 years
* dementia Risk Score 6 points or more
* fulfillment of at least one of the following CERAD criteria: i) MMSE: 20-26 points ii) word list memory task (3x10 words): 19 words or less iii) delayed recall: 75% or less

Exclusion Criteria:

* malignant diseases
* dementia
* substantial cognitive decline
* major depression
* symptomatic cardiovascular disease
* revascularisation within 1 year
* severe loss of vision, hearing or communicative ability
* other conditions inhibiting from safe engagement in the prescribed intervention as judged by the study physician
* other conditions preventing from cooperation as judged by the study physician
B: Inclusion Criteria:

* Engaged with the Lumosity program at least 3 days in the first week after sign-up
* Access to an internet enabled computer to complete training

Exclusion Criteria:

* Paying subscriber
C: Inclusion Criteria:

1. At least 60 years of age
2. Self-reported levels of proficiency in English (French for Montreal site only) for speaking and understanding spoken language.
3. Able to comply with scheduled visits, treatment plan, and other trial procedures
4. Able to ambulate at least 10 meters independently
5. Having MCI operationalized using Albert et al. criteria as:

   * objective cognitive impairment in one of the following four cognitive domains: memory, executive function, attention, and language evaluated by the Montreal Cognitive Assessment (MoCA) test with scores ranging from 13-24/30.
   * Preserved activities of daily living on the disability scale confirmed by clinician interview
6. Having normal or corrected to normal vision in at least one eye so that they can identify symbols and stimuli presented on a computer screen in front of them.
7. Must be in sufficient health to participate in the study's aerobic-based exercise training program, based on medical history, vital signs, physical examination by study physicians, or written recommendation by family physician indicating one's appropriateness to participate in aerobic-based exercise training program.

Exclusion Criteria:

1. Serious underlying disease (such as active cancer, or recent heart attack) which, in the opinion of the investigator, may preclude engagement in interventions or may interfere with the participant's ability to participate fully in the study.
2. Diagnosis of dementia using criteria from the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition.
3. Participant with uncontrolled major depression, schizophrenia, severe anxiety and substance abuse.
4. Current parkinsonism or any neurological disorder with residual motor deficits (e.g. stroke with motor deficit), active musculo-skeletal disorders (e.g. severe osteoarthritis of lower limbs) or history of knee/hip replacement affecting gait performance at clinical evaluation.
5. Intention to enroll in other clinical trials during the same time period
6. Pre-existing exercise structured training program involving aerobic or resistance training in previous 6 months.
7. Taking cognitive enhancers, neuroleptics, anticholinergics or Vitamin D3 in doses more than 1000IU/day or equivalent.
D: Inclusion Criteria:

* Age 70 to 85 years
* Summary score between 88 (80 for less than 8 years of education) and 95 on the Modified Mini-Mental Exam
* Sedentary lifestyle, i.e., not actively participating in a formal exercise program within the past 3 months (defined as 30 minutes or more of formal exercise at least once a week; brisk walks will be considered formal exercise, leisurely walks will not)
* Fluency in standard American English (to limit staffing and translation costs in this pilot)
* Willingness to be randomized to any of the four intervention conditions

Exclusion Criteria:

* Failure to provide the name of a personal physician
* Living in a nursing home; persons living in assisted or independent housing will not be excluded
* Unable to communicate because of severe hearing loss or speech disorder
* Severe visual impairment, which would preclude completion of the assessments and/or intervention
* Neurologic disease, e.g. Alzheimer's (or other types of dementia), stroke that required hospitalization, Parkinson's, multiple sclerosis, amyotrophic lateral sclerosis, or prior diagnosis of mild cognitive impairment (MCI)
* Abnormal functioning based on the modified Telephone Interview for Cognitive Status (less than 30)
* Positive screen for MCI or dementia
* Scores greater than or equal to 1.5 standard deviations below normal on memory and non-memory domain tests (speed of processing, and verbal fluency)
* Severe rheumatologic or orthopedic diseases, e.g., awaiting joint replacement, active inflammatory disease
* Terminal illness with life expectancy less than 8 months, as determined by a physician
* Severe pulmonary disease, e.g., on home oxygen or chronic steroids
* Severe cardiac disease, including New York Health Association Class III or IV congestive heart failure, clinically significant aortic stenosis, history of cardiac arrest which required resuscitation, use of a cardiac defibrillator, or uncontrolled angina
* Other significant co-morbid disease that would impair ability to participate in the exercise-based intervention, e.g. renal failure on hemodialysis, severe or acute psychiatric disorder (e.g. bipolar disorder or major depression, schizophrenia), excessive alcohol use (more than 14 drinks per wk); persons with managed depression (on stable dosage for at least 3 months) will not be excluded
* Baseline Geriatric Depression Scale score greater than 6
* Other significant factors that may affect the ability for cognitive training, including a history of head trauma resulting in a loss of consciousness, current use of benzodiazepines, hypnotic or anticholinergic agents, and current use of cognitive enhancing prescription or investigational medications (e.g., donepezil, selegiline, tacrine)
* Member of household is already enrolled
* Lives distant from the study site or is planning to move out of the area in next 3 years or leave the area for more than 3 months during the next year
* History of participation in a cognitive program in the last 2 years (includes research studies involving memory training)
* Myocardial infarction, coronary artery bypass graft, or valve replacement within past 6 months
* Serious conduction disorder (e.g., 3rd degree heart block), uncontrolled arrhythmia
* Pulmonary embolism or deep venous thrombosis within past 6 months
* Stroke, hip fracture, hip or knee replacement, or spinal surgery within past 4 months
* Receiving physical therapy for gait, balance, or other lower extremity training
