Novel conceptual framework for tackling the global challenge of dementia
30 July 2015
A novel conceptual framework for tackling the global challenge of dementia has been proposed in an article published in The Lancet.
Professor Martin Rossor, UCL Institute of Neurology and the National Hospital for Neurology and Neurosurgery (UCLH), and Professor Martin Knapp, LSE, have suggested modelling a “cognitive footprint” of activities, interventions and policies.
Mental skills such as memory, awareness, judgment, and
problem-solving are required to carry out any knowledge-based task.
Development of these cognitive abilities is affected by environmental
and lifestyle factors – from even before birth right through to later
These abilities affect the well-being of the individual, and the overall social and economic well-being of a nation. The cognitive potential of a population determines its cognitive capital, which is a key resource for creating wealth through better skills, more efficient communication, research breakthroughs and technological innovation.
The concept of a cognitive footprint starts with the premise that the cognitive potential of any individual should be realised, and the lifetime contribution of any individual to a society’s cognitive capital should be maximised.
Drawing an analogy with the concept of a carbon footprint, it is suggested that a cognitive footprint can be developed for individual actions and interventions and also for national and local policies.
The impetus for developing the concept arose from concern around the focus of the dementia challenge on late life dementia and particularly on Alzheimer’s disease. Whilst recognising this is a cause for major concern because of changing demographics it risks losing sight of the importance of less severe impairments of cognition due to many different diseases. It also argues for a life course perspective rather than focussing on late life.
