The "intervention group" will participate in the 6-month interdisciplinary comprehensive rehabilitation program. The ABI Wellness (ABIW) program aimed at this population would be 7 hours a week (2 days per week will be scheduled for the intervention group), consisting of around 4 hours of cognitive training (through specified drills, cognitive exercises focused on executive functioning), 1 hour of physical exercise, 1 hour of mindfulness sessions (meditation) and scheduled break times.

The "non-intervention" group or control group will have all the same pre-tests administered as the intervention group, however, will not participate in the cognitive program. The control group will be required to complete the assessment periods only, however, keep a record of their daily activities in a log format which is presented in the materials included herein. No other intervention or programming will be provided.

The ABI Wellness program includes a computerized task which will be completed by all participants remotely. The exercise is a sustained visual-spatial processing task of progressively increasing difficulty. Subjects are presented with an analog clock face, initially showing only one hand. The subject uses a keyboard to enter a value for the hour shown. Feedback on the computer screen indicates whether the response is correct or incorrect. If the response was incorrect, the subject continues to respond until the correct response is entered. After this, a new clock face is shown. Once subjects reach a criterion of 90% accuracy over a series of consecutive responses, an additional hand is added to the clock face. Participants will complete the program at home, online, and will be required to be present on a video call during the exercise with the other participants and research assistants. The program is 150 hours over 6 months, through twice weekly 3-hour sessions.

Telephone Montreal Cognitive Assessment (T- MoCA) - non-invasive screening tool which takes approximately 10 minutes to complete. Thirty items assessing multiple cognitive domains are contained in the MoCa: short-term memory; visuospatial abilities via clock drawing; and a cube copy task; executive functioning via an adaptation of Trail Making phonemic fluency, and verbal abstraction; attention, concentration, and working memory via target detection, serial subtraction, digits forward, and digits backward; language via confrontation naming with low-familiarity animals, and repetition of complex sentences; and orientation to time and place (Nasreddine et al., 2005). The MoCA is scored by obtaining an item total.

Memory Alteration Test (M@T) - A non-invasive memory screening test used to discriminate between subjects with subjective memory complaints (SMC) Without objective memory impairment and patients with amnesic mild cognitive impairment (A-MCI) and with Mild Alzheimers disease (AD). (M@T), which is a memory screening test, capable for discriminating between subjects with subjective memory complaints (SMC) (without objective memory impairment) and patients with amnestic mild cognitive impairment (A-MCI) and with mild Alzheimer's disease (AD). This is a cognitive test with high internal consistency and validity, short application (5-10 min), easy to perform and to interpret (Carnero-Pardo et al., 2011a).

Mild Cognitive Impairment Questionnaire (MCQ) -QOL will be measured using the 13-item MCQ tool designed to take 5 minutes to administer. The MCQ tool uses a scale of 0-4 (none, rarely, sometimes, often, or always) to assess two constructs - Practical Concerns and Emotional Concerns. Scores are transformed and presented on a metric of 0 (no problems) to 100 (maximum impact of MCI). Scale scores are interpreted using the following guide: a scale score of 0-20 indicates 'never' experiencing the issue, 21-40 'rarely' experiencing it, 41-60 'sometimes' experiencing it,61-80 'often' experiencing it, 81-100 'always' experiencing it. The MCQ has been shown to have great stability and reliability through test-retest and substantial validity with this population.

Interviews - Semi-structured interviews will occur with all participants in the study including the intervention and the control group with a focus upon lived experience specific to quality of life.
