Technical Summary
Developing effective treatment for dementia critically depends on characterising the development and progression of cognitive decline many years prior to current dementia diagnosis. ContinUous behavioUral Biomarkers Of cognitive Impairment (CUBOId) leverages a £12M investment in the EPSRC Sensor Platform for HEalthcare in a Residential Environment (SPHERE) Interdisciplinary Research Collaboration, which aims to advance the state of the art in sensing for many different health-related behaviours at home.
The objective of this proposal is to develop novel computational behavioural analysis algorithms that derive signatures relevant to dementia from SPHERE’s sensor network. Using these new algorithms, CUBOId aims to demonstrate that it is possible to reveal previously unseen behavioural biomarkers of early Alzheimer’s disease (AD) pathology, derived from autonomous, continuous, long-term, behavioural measurement.
As proof of principle, enhancing diagnosis will be explored through testing the hypothesis that in Mild Cognitive Impairment (MCI), where subtle cognitive deficits can be difficult to interpret, there is a behavioural AD signature identifiable using SPHERE technology. Second, we explore the hypothesis that behavioural markers of AD observable with this technology will be more sensitive to treatment effects than standard cognitive measures used in clinical trials.
In so doing, the CUBOId team will have developed, tested and de-risked a unique new asset for the community of researchers in the UK Dementias Research Institute, which can also be applied to cohorts in the Dementias Platform UK as well as internationally. Importantly, the proposed proleptic appointment of a “rising star” at Bristol is intended to develop the potential of SPHERE-type sensors and algorithms specifically for use in dementia; to nurture the important interface between computer science and dementia research at the University and to personally lead engagement between Bristol and the DRI.

| Title | Mild Cognitive Impairment Clinic |
| Description | We have established a clinical service for patients who have mild memory symptoms. The aim of this is to provide early accurate diagnosis, prognostic information and research opportunities - notably the CUBOID study when appropriate. We are using standard clinical tests - neuropsychology, blood tests, neuroimaging and CSF biomarkers - to stratify patients at an earlier stage of disease when both the patient and GP request it. |
| Type Of Material | Model of mechanisms or symptoms - human |
| Year Produced | 2017 |
| Provided To Others? | No |
| Impact | We are planning to evaluate this new service after 1 year. Important outcomes will be patient experience and research recruitment rates. |

| Form Of Engagement Activity | A formal working group, expert panel or dialogue |
| Part Of Official Scheme? | No |
| Geographic Reach | Local |
| Primary Audience | Public/other audiences |
| Results and Impact | A PPI event was run by the ReMemBr group. The purpose was to raise awareness of the CUBOId project and collect feedback on how we should proceed with recruitment and overcome any foreseeable challenges. The event was a success, generating positive discussion. Participants felt reassured that the home sensor technology is not intrusive. Ideas were also generated on how we might reassure potential participants, such as showing them photographs of what the equipment looks like when it has been installed in people's homes. We intend to obtain permission to use photographs of people's homes that are currently involved in the related SPHERE 100 Homes project. |
