Question to the Department of Health and Social Care:

To ask the Secretary of State for Health and Social Care, what research his Department has undertaken on potential links between dementia and depression.

The Department delivers dementia research via the National Institute for Health and Care Research (NIHR). Recently completed NIHR-funded research has found that depression across the life course is associated with an increased risk of dementia, but that this is strongest in mid to late life. Further research is needed to determine whether the strength of this association is due to depression as a risk factor for dementia or the early presentation of neurodegenerative processes.

The NIHR is funding the £2.9 million ENHANCE programme, which will develop an app intervention to address risk factors for dementia, including depression, and will test it to see the effects on cognition, risk, quality of life, and affordability. In the long-term, the research will examine health records to see if the app intervention has reduced rates of dementia. NIHR-funded research is also seeking to understand whether compassion focused therapy is an acceptable intervention for people with dementia and depression or anxiety.

The NIHR continues to welcome funding applications for research into any aspect of human health and care, including dementia. These applications are subject to peer review and judged in open competition, with awards being made on the basis of the importance of the topic to patients and health and care services, value for money, and scientific quality. Welcoming applications on dementia to all NIHR programmes enables maximum flexibility both in terms of the amount of research funding a particular area can be awarded, and the type of research that can be funded.
