Primary Outcome(s)

Main Objective: This is a feasibility study designed to inform the following process / primary outcomes:
• to obtain estimates of memory performance which will inform a power calculation;
• to explore with patient-participants and carers barriers to participation which include management of symptoms during washout period. This will be achieved formally using the end of study focus group as well as informally during mid-and end of study clinic visits with clinical members of research team, and during ON/OFF research visits with the PhD student/assessor.

Primary end point(s): This is a feasibility study designed to inform the following process outcomes:

- to obtain estimates of memory performance which will inform a power calculation;

- management of symptoms during washout period

Secondary Objective: • drop-out rate;
• effectiveness of recruitment strategy;
• identification of training needs of members of the research team and patient-participant participant panel (PPI);
• to obtain estimates of memory performance which will inform a power calculation gathered during ON and OFF research sessions;
• establish the likely staffing resources and timetable needed for the subsequent main study;
• validate composition of the neuropsychological test battery;
• to gather personal reflections of patient-participant participants and public and patient-participant involvement (PPI) members on their respective research experience.
• to explore with patient-participants and carers barriers to participation which include
o relative timing of ON and OFF sessions in each treatment arm
o duration of the ON and OFF research sessions.

Timepoint(s) of evaluation of this end point: End of study.
