STRATEGIES to Improve Memory in Alzheimer's Disease

Summary

Memory mistakes are one of the most detrimental symptoms in Alzheimer's Disease (AD). In this study the investigators will measure the long-term efficacy of memory strategies in patients with AD. First, the efficacy of the strategies will be evaluated in the laboratory by analyzing the behavioral response and the brain activity of the patients. During the first visit, patients will be taught the memory strategies and asked to repeat them at home for 4 weeks. During this period of time, patients will perform several memory tasks while their performance and brain activity will be measured using portable devices. Monitoring brain activity and behavioral responses to memory tasks will provide insightful information on the efficacy of the strategies and allow the investigation of how patients can maintain the strategies over time. The research will examine if improving memory through the use of cognitive strategies, can positively affect other domains of daily life.

Conditions

• Alzheimer Disease
• Dementia, Mild
• Mild Cognitive Impairment

Interventions

BEHAVIORAL

Memory strategies in Arm 1

Memory strategies will consist of daily at-home exercises lasting between 20 minutes to 1 hour depending on the memory tasks assigned to each participant. At the start of week 1 participants will be taught the memory strategies to use while completing the daily memory tasks. In week 1 and 2, subjects will be reminded daily to use the memory strategies. At the start of week 3, subjects will be advised to use the memory strategies however they will not be given daily reminders.

DEVICE

Electroencephalogram (EEG) headset in Arm 1

A cap that measures brain activity using a 16-sensor wireless dry (no gel applied) EEG device designed by BrainWaveBank Ltd., that uses Bluetooth technology to securely transmit EEG signals to an Android tablet. The cap will be used during week 1,2,3 and 4.

OTHER

Tablet in Arm 1

A computer tablet will be provided to each participant that will have daily reminders about the memory strategies during week 1 and 2, while no reminders will be present in week 3 and 4. The tablet software includes a user-friendly interface that provides feedback and instructions that help the participant properly wear the EEG headset. At the end of each session the tablet stores behavioral and EEG data on a secured server accessible by the research staff.

BEHAVIORAL

Memory strategies in Arm 2

Memory strategies will consist of daily at home exercises lasting between 20 minutes to 1 hour depending on the memory tasks assigned to each participant. During weeks 1 and 2, participants will be completing the memory tasks without being instructed to use any specific strategy. At the end of week 2 subjects will be taught the memory strategies and during week 3 and 4, they will be reminded daily to use the memory strategies while completing the memory tasks.
