Online Brain Training Intervention for Over 50s

Study Overview
=================
Brief Summary
-----------------
This study is an open trial investigating the long-term use of an online brain training programme for adults over 50. It will determine whether there is sustained benefit to cognition, and whether this group can be engaged in this form of intervention over a period of 12 months.

Detailed Description
-----------------
This study will evaluate an optimised brain training programme to determine whether it is engaging for older adults and whether it results in improvement or maintenance of cognition over a 12 month period. The Brain Training intervention The programme is an updated version of the original 'Brain Test Britain' intervention, which was successfully evaluated in a large previous trial. It consists of a series of games or tests, completed on a computer. Each test is designed to target the participants' reasoning and problem-solving ability, for example by asking them to balance weights on a see-saw or select the 'odd-one-out' from a series of shapes. As the participants progress over the course of the study they will receive increasingly more challenging versions of each test, depending on their performance. The intervention has been updated from the original to improve engagement through improved visuals, more intelligent difficulty setting and a more engaging delivery platform. The research delivery platform: PROTECT A novel infrastructure resource has been developed at King's College London within the Maudsley Biomedical Research Unit for Dementia (BRU-D), which provides the opportunity to deliver the intervention to large numbers of older adults. The Platform for Research Online to investigate Cognition and Genetics in Ageing (PROTECT) is an online research tool. PROTECT is currently recruiting a cohort of over 10,000 adults over 50 who are cognitively healthy or have early cognitive impairment. Participants provide demographic and lifestyle information and will complete a battery of validated cognitive assessments annually. The focus of all research conducted through PROTECT is on the prevention of dementia and risk reduction. The optimised brain training intervention will be delivered through this platform. PROTECT has ethical approval from the NHS Research Ethics Service Committee for London Bridge (Ref: 13/LO/1578). Study Design Design: 12-month open online clinical trial Participants: 5000 adults over 50 Setting: Intervention delivered at home, online through the PROTECT website Recruitment Recruitment will be achieved through the PROTECT site through a national advertisement strategy. This will be accomplished through partnerships with the media and third sector. All participants registered on PROTECT will be invited to take part and provided with the information sheet. Participants will consent through the secure online procedure on the PROTECT site.
