Dementia with Lewy bodies (DLB) is one of the most common subtypes of dementia. Although DLB shares characteristics with Alzheimer's disease, the condition requires specific treatment and care. New diagnostic criteria generated at Newcastle allow diagnosis of DLB as a distinct condition from Alzheimer's, and these criteria have been incorporated into five national and international guidelines. The work also resulted in an accurate and sensitive diagnostic technique, commercialised by GE Healthcare as the DaTSCAN imaging tool, which is approved by the US Food and Drug Administration and the European Medicines Agency. These new diagnostic criteria allow appropriate treatment and management of DLB for the first time.
Dementia is one of the greatest problems facing society today, both in financial terms and in terms of the quality of life of patients and caregivers. Newcastle research identified that cholinesterase inhibitors (CHEIs), originally licenced for use in Alzheimer's disease, would be of greater benefit in two other types of dementia; Lewy body dementia and Parkinson's disease. CHEIs are now recommended in national and international guidelines as a treatment for the cognitive and psychiatric symptoms associated with both of these conditions, which previously had no effective treatment. CHEIs are also licenced worldwide for use in Parkinson's dementia, and are used off- licence across the world as a first-line treatment for dementia with Lewy bodies.
Newcastle research on dementia contributed two aspects that helped to shape high-level policy: first that prevalence of the condition was higher than previously suspected, with implications for care of the ageing UK population. Secondly, that patients often experienced long delays before a diagnosis of dementia was given, leading to distress both for patients and their families. This research informed policy documents such as the Prime Minister's 2012 Challenge on dementia and national guidance in the form of commissioning packs. Patients benefit from more timely diagnosis with a better understanding of their needs and wishes and the NHS benefits through potential reductions in long term care costs.
Dementia poses substantial public health and societal challenges for Europe as there is currently no cure, and it is estimated that 10 million Europeans will be living with the disease in 2040. Good quality information allows for decision-makers to establish appropriate health policies and target resources where they are needed and where they are effective. The ALCOVE project (2011-2013) established a European network where knowledge on dementia could be shared and developed a series of recommendations for improving dementia care and quality of life across Europe. A particular strand of research within the project on timely diagnosis of dementia led by Worcester's Association for Dementia Studies has already stimulated policy debate on this issue in the UK and elsewhere in Europe, while a `toolbox' developed through the project for those living with dementia and their carers and for health and social care professionals has informed care practice.
Research by Professor Carol Brayne, has led to increased understanding and awareness of dementia as a key public health issue of our time. Outcomes of her DH/MRC funded longitudinal Cognitive Function and Ageing Studies (CFAS) have contributed to national and international health policy on dementia as well as public debate.
Specifically, the CFAS study provided evidence that was used in the highly influential report "Dementia UK" which led to the development of the 2009 National Dementia Strategy. Results from CFAS have increased healthcare workers' understanding of the condition, such as the complexity of cognitive impairment and the relationship between illness and disability.
CANTAB-Paired Associates Learning (PAL) was developed to detect early memory problems in Alzheimer's disease; and was recently (in 2012) launched by Cambridge Cognition (floated on the London Stock Exchange in April 2013) as a mobile (iPad) application (CANTABmobile™) suitable for use in GP clinics. This and other cognitive tests from the CANTAB battery have also been employed in 77 clinical trials since 2008, involving hundreds of sites world-wide, by most of the major pharmaceutical companies and by biotech, device and nutraceutical companies. CANTABmobile™ currently has 166 licensed user-practitioners including six clinical commissioning groups implementing the national initiative for early diagnosis.
Research carried out by Professor David Smith of the University of Oxford established that B vitamins could slow the rate of Alzheimer-related brain atrophy and cognitive decline in people with mild cognitive impairment (MCI), an early stage of Alzheimer's disease which is common in the elderly. Since 2008 the impact on sales and marketing of B vitamins worldwide has been significant; [text removed for publication], and over-the-counter and prescription B vitamin products marketed as helping to maintain memory function have achieved sales worth many millions of US dollars. Some doctors now prescribe B vitamins for the group of MCI patients identified by Smith as being most at risk.
