Effectiveness of Home-based Electronic Cognitive Therapy in Alzheimer's Disease

Changes in cognition as measured by the Mini Mental Status Exam

Participants will be administered the Mini Mental Status Exam (MMSE) to both the intervention and control groups. This will occur prior to any to type of intervention (Month 0). Scores on the MMSE range from 0 to 30. Specifically the investigators are examining if cognitive status changes as measured by the MMSE prior to intervention (Month 0), and post-intervention (Month 6). The investigators will compare changes in MMSE scores both pre- and post- in the intervention group, but also compare performance on these measures to the control group.

Time frame: Month 0 (Prior to administration of cognitive rehabilitation tasks) and Month 6 (after administration of cognitive rehabilitation tasks)

Changes in cognition as measured by the Montreal Cognitive Assessment

Participants will be administered the Montreal Cognitive Assessment (MoCA) to both the intervention and control groups. This will occur prior to any to type of intervention (Month 0). Scores on the MoCA range from 0 to 30. Specifically the investigators are examining if cognitive status changes as measured by the MoCA prior to intervention (Month 0), and post-intervention (Month 6). The investigators will compare changes in MoCA scores both pre- and post- in the intervention group, but also compare performance on these measures to the control group.

Time frame: Month 0 (Prior to administration of cognitive rehabilitation tasks) and Month 6 (after administration of cognitive rehabilitation tasks)

Changes in cognition as measured by the Consortium to Establish a Registry in Alzheimer's disease Word List Test

Participants will be administered the Consortium to Establish a Registry in Alzheimer's disease Word List Learning Test (CERAD) to both the intervention and control groups. This will occur prior to any to type of intervention (Month 0). The CERAD measures the immediate recall of a list of words (up to 30 correct recall on 3 individual recall trials), delayed recall (up to 10 correct recall after a 5 minute delay), and on yes-no recognition memory (up to 10 correct recognition). Specifically the investigators are examining if list learning changes as measured by the CERAD prior to intervention (Month 0), and post-intervention (Month 6). The investigators will compare changes in CERAD scores both pre- and post- in the intervention group, but also compare performance on these measures to the control group.

Time frame: Month 0 (Prior to administration of cognitive rehabilitation tasks) and Month 6 (after administration of cognitive rehabilitation tasks)

Changes in cognition as measured Letter and Category Fluency

Participants will be administered the Letter and Category Fluency to both the intervention and control groups. This will occur prior to any to type of intervention (Month 0). For letter fluency, participants name as many words as possible in a minute that start with the letters F, A, and S. For category fluency, participants name as many words as possible in a minute that are within the Animals, Vegetables, and Fruits categories. Specifically the investigators are examining if fluency changes as measured by the fluency prior to intervention (Month 0), and post-intervention (Month 6). The investigators will compare changes in fluency scores both pre- and post- in the intervention group, but also compare performance on these measures to the control group.

Time frame: Month 0 (Prior to administration of cognitive rehabilitation tasks) and Month 6 (after administration of cognitive rehabilitation tasks)

Changes in cognition as measured by the Boston Naming Test (Short Form)

Participants will be administered the Boston Naming Testing Short Form (BNT-15) to both the intervention and control groups. This will occur prior to any to type of intervention (Month 0). The BNT-15 consists of 15 line drawings (with a maximum score of 15 correct). Specifically the investigators are examining if confrontation naming of line drawings as measured by the BNT-15 prior to intervention (Month 0), and post-intervention (Month 6). The investigators will compare changes in fluency scores both pre- and post- in the intervention group, but also compare performance on these measures to the control group.

Time frame: Month 0 (Prior to administration of cognitive rehabilitation tasks) and Month 6 (after administration of cognitive rehabilitation tasks)

Changes in cognition as measured by the Trail Making Parts A & B

Participants will be administered the Trail Making Test (Parts A \& B) to both the intervention and control groups. This will occur prior to any to type of intervention (Month 0). The Trail Making Test Part A consists of connecting a series a numbers with a line in ascending order as quickly as possible (performance is timed, the score is the time it takes to finish). The Trail Making Test Part B consists of connect a series of letters and numbers, alternating back and forth between them, as quickly as possible in ascending order (performance is timed, the score is the time it takes to finish). Specifically the investigators are examining if Trail Making performance as measured by the Trail Making Tests prior to intervention (Month 0), and post-intervention (Month 6). The investigators will compare changes in fluency scores both pre- and post- in the intervention group, but also compare performance on these measures to the control group.

Time frame: Month 0 (Prior to administration of cognitive rehabilitation tasks) and Month 6 (after administration of cognitive rehabilitation tasks)
