Clinical Trial Summary

The current study will examine the use of a mobile electronic application used to deliver cognitive rehabilitation to patients with mild cognitive impairment due (MCI) due to Alzheimer's disease (AD), and patients with mild AD. Patients will be given a specific cognitive rehabilitation program on their mobile device (iPad) with specific tasks for them to complete. The goal of this study is to determine if a) patients are able to use and adhere to a cognitive rehabilitation program delivered to their mobile device and b) to determine if patients can improve their language, attention, and memory by completing cognitive rehabilitation tasks assigned to them.

Description:

In the current study, the investigators are examining the use of a mobile electronic application used to deliver cognitive rehabilitation tasks to patients with mild cognitive impairment due to Alzheimer's disease, and patients with mild Alzheimer's disease. An estimated 100 patients will be enrolled into the study (~50 patients with mild cognitive impairment, ~50 patients with Alzheimer's disease). Participants will either receive memory tasks designed to help stabilize or improve memory (Intervention Group) or a set of word or math puzzles (Control Group). Participants will complete memory tasks or puzzles for a six month period. The investigators will conduct pre- and post- neuropsychological testing to assess changes in cognitive status (e.g., memory, language, executive functioning) in the intervention group. Neuropsychological tests assessing changes to cognition will be completed prior to participant assignment to the Intervention or Control Group. Both groups will then be assessed again using neuropsychological tests. The investigators will also assess changes in performance on cognitive rehabilitation tests over the six month period to determine the efficacy of these tasks.

Intervention

Behavioral:
• Intervention Group
The investigators are interested in how practicing memory tasks can improve memory in patients with MCI and with AD. Specifically, patients will perform a set of cognitive rehabilitation tasks designed to train memory in order to determine if these tasks are effective in improving memory or slowing the progression of Alzheimer's disease. Patients will practice memory tasks for about an hour daily, for a total duration of 6 months. A research assistant or clinician will conduct weekly check-ins with each participant assess whether or not participants in the Intervention Group exhibit weekly improvements and to determine if patients are regularly adhering to the tasks.
• Control Group
The Control Group will not receive any cognitive rehabilitation tasks for a six month period. Instead, they will simply be given booklets of puzzles (e.g., word search, number puzzles, etc.) to work on for the duration of 6 months. A research assistant or clinician will conduct weekly check-ins with each participant assess whether or not participants in the control group feel like they are benefiting from the puzzles. Participants in the Control Group will be given a standard battery of neuropsychological tests prior to the the puzzles and after the puzzles to assess any changes in memory, language, attention, and executive functioning.

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.	Month 0 (Prior to administration of cognitive rehabilitation tasks) and Month 6 (after administration of cognitive rehabilitation tasks)
Primary	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.	Month 0 (Prior to administration of cognitive rehabilitation tasks) and Month 6 (after administration of cognitive rehabilitation tasks)
Secondary	Changes in performance on cognitive rehabilitation tasks (composite measure of memory tasks)	In the intervention group, the investigators will examine speed and accuracy data on all cognitive rehabilitation memory tasks. Tasks will be converted into a single memory composite measure (for both speed and accuracy data).; The investigators will cull performance on the tasks on a weekly basis. Weekly data will be treated as a single data points. Participants will be followed for approximately 24 weeks (or 6 months).; The investigators will use a regression analysis to analyze to determine changes in the slope on speed and accuracy for each of these data points. Additionally, the investigators will use inferential statistics, such as ANOVA, to determine if participants improve on a week by week basis. These analyses will be conducted on the composite of memory data collected from all the memory tasks.	During intervention (6 month time frame, composite measure)
