Memorandum by The Stroke Association

  The Stroke Association has been the major funder of research into all aspects of stroke illness and its care including prevention. The Association has a major concern for the prevention of disability through the primary prevention of strokes and transient ischaemic attacks (TIAs), improvements in the early management of stroke illness (the creation of stroke units) and the effective rehabilitation both immediately after the acute episode and in the longer term. The Association is concerned to assist patients achieve independence through adjustment to disability and effective rehabilitation. The case is compelling:

    —  Suffering a stroke increases the chances of disability more markedly than any other condition.

    —  Stroke is a more powerful cause of disability than musculo-skeletal and other chronic disorders.

    —  Stroke has a greater disability impact than other chronic diseases.

    —  Stroke causes a greater range of disabilities than any other condition.

    —  A quarter of a million people suffer with long-term severe disability due to stroke in the UK.

  The conclusions from the research conducted for the Association informs the care of all older people with disability[1] and for this reason and because stroke services are covered by standard 5 of the National Service Framework for Older People it has been appropriate for the Stroke Association to serve as a member of the Funders' Forum.

THE BIOLOGICAL PROCESSES OF AGEING

    —  What are promising avenues for research? How will such research benefit older people and delay the onset of long-term illnesses and disabilities?

  Derek Wanless has focussed on the importance of life style factors in the development and progress of chronic illness. Older people stand to be major beneficiaries of the change in emphasis that Wanless recommends. Whereas the benefits have been identified effective strategies for bringing about these benefits have not been defined.

  The report from the Academy of Medical Sciences "Restoring neurological function: putting the neurosciences to work in neurorehabilitation" prepared by Professors Ray Tallis and Richard Frackowiak identifies the opportunities which research in to rehabilitation presents.

    —  Differences between the sexes, and between different social and ethnic groups in the UK.

  Although there is a social gradient for stroke as for coronary heart disease this is not presently afforded a high priority. On the other hand Professor Hugh Markus (St George's Hospital, research supported by the Stroke Association) reporting on his research concludes: "Individuals of African and African Caribbean descent living in the United Kingdom and the United States have a markedly increased risk of stroke compared with white individuals. In a recent population stroke registry study in London, UK, African Caribbeans had a doubling of stroke incidence compared with that of whites. This increased incidence remains after adjustment for cardiovascular risk factors and socioeconomic status. The reasons for this increase in stroke risk are uncertain, although the increase in risk could be related to differences in the prevalence of cardiovascular risk factors or susceptibility to them, reduced access to or utilization of medical care, uncontrolled for socioeconomic factors (including associated environmental factors), and/or differing genetic predispositions."

Professor Markus's study reached the conclusion that—more advanced deleterious changes in the wall of the carotid arteries (atheroma) occur in UK African Caribbeans even after controlling for conventional risk factors. There are highly significant ethnic differences in the distribution of many potential cerebrovascular candidate genes. Although those examined did not explain the ethnic differences in extent of damage to the carotid arteries, other genetic predispositions or environmental exposures could account for these differences[2].

    —  How effectively is research co-ordinated in the public, private and charitable sectors (including internationally)?

    —  Have the correct priorities been identified? Are there any gaps in research?

  The Funders' Forum for Research in Ageing and Older People has identified priorities for research in its field and gaps. The list is included here because it is relevant but it will have been discussed in greater detail in a submission from the MRC.

    —  the psychology of ageing, disability and dependence;

    —  the economic and social implications, behaviour and aspirations of an ageing population;

    —  technologies and design to help people maintain independence and autonomy and their effects on older people;

    —  technologies for the detection, prediction, diagnosis and treatment of age related disease, and the effects of these technologies on older people;

    —  the molecular and cellular changes associated with basic biological processes of cell death, senescence and physiological ageing;

    —  the causes of, and influences on age related diseases and disability;

    —  prevention of breakdown in health and loss of independence in old age and of specific diseases and conditions which cause these;

    —  treatment of disease and breakdown in health in older people;

    —  rehabilitation strategies to improve and maintain function and restore independence; and

    —  the delivery of effective and efficient health and social care for old and frail people.

DISCUSSION OF THESE TOPICS IN THE FFRAOP BUSINESS PLANNING GROUP LED TO THESE CONCLUSIONS: (SEPTEMBER 2003)

    "High quality research in basic sciences in relation to ageing, and research in the epidemiology, causes, prevention and treatment of disease in old age should continue to be supported. Research which is of particular relevance to ageing should be identified and categorised.

    What is relatively sparse is multi-disciplinary research into the causes, prevention, and rehabilitation of multi-factorial breakdown of independence in old age. Research in ageing and older people requires a new strategy."

CO-ORDINATION

  Research has depended upon support from a number of relatively small medical research charities faced with a set of research priorities, which has inhibited collaboration on more ambitious research.

  The Research Councils point to a considerable amount of research funded by them which is taking place in many of the common diseases of adults as well as older people. They point to a considerable amount of basic research being undertaken in the biological, social and behavioural sciences, some of which may be specifically directed at ageing and some of the rest will have implications for ageing. Close examination of the previous research strategies suggests that the issues specific to the needs of older people have been neglected.

THESE ARE VERY SIMILAR TO THE RECOMMENDATIONS PROPOSED BY THE NHS STRATEGIC REVIEW ON AGEING AND AGE-ASSOCIATED DISABILITY, WHICH REPORTED IN JUNE 1999. PROGRESS HAS BEEN VERY DISAPPOINTING

    —  Is there sufficient research capability in the UK?

    —  Is the research being used to inform policy?

DEFINITELY NOT . . .

  The Stroke Association has placed a high priority upon the building of the research capacity in physiotherapy, occupational therapy, speech and language therapy and nursing. It has offered a small number of research bursaries annually for 10 years. The Association welcomes recent initiatives made by the DoH.

THE APPLICATION OF RESEARCH IN TECHNOLOGY AND DESIGN TO IMPROVE THE QUALITY OF LIFE OF OLDER PEOPLE, INCLUDING:

    —  Existing technologies which could be used to a greater extent to benefit older people.

    —  The development of new technologies.

  Research in this area consists of pilot projects and the design of exciting prototypes only. Funding is required to expand these pilot studies into extensive trials.
