Title: Computer-Based Therapy for Mild Cognitive Impairment
Brief Summary: The purpose of this study is to determine the neuropsychological and neurophysiological impacts of a computer-based training program designed to improve the cognitive performance of patients with mild cognitive impairment (MCI).

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:

1)65 - 90 years of age 2)Meet definition for MCI including complaints of cognitive decline as indicated by patient report and/or informant report, and corroborated by clinician judgment and, the absence of dementia, defined as impairment of memory and at least one other domain of cognitive function.
