Ageing and learning disability

Iatrogenic Alzheimer's disease in recipients of cadaveric pituitary-derived growth hormone

Alzheimer's disease (AD) is characterized pathologically by amyloid-beta (Aβ) deposition in brain parenchyma and blood vessels (as cerebral amyloid angiopathy (CAA)) and by neurofibrillary tangles of hyperphosphorylated tau. Compelling genetic and biomarker evidence supports Aβ as the root cause of AD. We previously reported human transmission of Aβ pathology and CAA in relatively young adults who had died of iatrogenic Creutzfeldt-Jakob disease (iCJD) after childhood treatment with cadaver-derived pituitary growth hormone (c-hGH) contaminated with both CJD prions and Aβ seeds. This raised the possibility that c-hGH recipients who did not die from iCJD may eventually develop AD. Here we describe recipients who developed dementia and biomarker changes within the phenotypic spectrum of AD, suggesting that AD, like CJD, has environmentally acquired (iatrogenic) forms as well as late-onset sporadic and early-onset inherited forms. Although iatrogenic AD may be rare, and there is no suggestion that Aβ can be transmitted between individuals in activities of daily life, its recognition emphasizes the need to review measures to prevent accidental transmissions via other medical and surgical procedures. As propagating Aβ assemblies may exhibit structural diversity akin to conventional prions, it is possible that therapeutic strategies targeting disease-related assemblies may lead to selection of minor components and development of resistance.

Developmental language disorder - a comprehensive study of more than 46,000 individuals

Developmental language disorder (DLD) is characterized by enduring low language abilities with a significant functional impact, in the absence of biomedical conditions in which language impairment is part of a complex of impairments. There is a lack of awareness of DLD even among healthcare professionals. Here we estimated the prevalence of DLD and its links to reading and learning difficulties and physical and mental health in the Danish Blood Donor Study (N = 46,547), where DLD-related information is based on questionnaires (self-report). We compared the questionnaire-derived DLD status with the relevant language-related diagnoses from hospital registers. We also investigated the genetic architecture of DLD in a subset of the cohort (N = 18,380). DLD was significantly associated with reading and learning difficulties and poorer mental and physical health. DLD prevalence was 3.36%-3.70% based on questionnaires, compared with 0.04% in hospital registers. Our genetic analyses identified one genome-wide significant locus, but not a significant heritability estimate. Our study shows that DLD has health-related implications that may last into adulthood, and that DLD may be undiagnosed in general healthcare. Furthermore, DLD is likely more genetically heterogeneous than narrower developmental language phenotypes. Our results emphasize the need to raise awareness of DLD and consider criteria for molecular studies of DLD to reduce case heterogeneity.

Examining the effects of computerised cognitive training on levels of executive function in adults with Down syndrome

BACKGROUND

Individuals with Down syndrome (DS) are at much greater risk of developing Alzheimer's disease, and one of the early clinical symptoms of Alzheimer's disease is executive dysfunction. In the general population, cognitive training has shown some promising results in relation to maintaining or improving cognitive processes. There is currently a gap in the literature in relation to cognitive training for adults with DS.

METHODS

A quasi-experimental mixed factorial design with partial crossover was used involving an 8-week intervention period using a brain training programme. Participants were matched on age and then randomly assigned to either the intervention group or the delayed intervention group. Forty adults with DS, aged between 30 and 49 and with a mild or moderate level of intellectual disability, participated in the study. All participants completed baseline measures of executive function, using both neuropsychological assessments and an informant-rated measure of behavioural executive function. The intervention group first completed the training and then the delayed intervention group. Executive function assessments were repeated for both groups following the training.

RESULTS

The study aimed to examine whether a cognitive training programme could have an effect on levels of executive function. While conclusions are limited owing to small sample size, improvement was seen in neuropsychological assessments of executive function following cognitive training. Positive effects reflected in everyday behaviours were not as promising.

CONCLUSIONS

This study showed that, while it has not been previously an area of focus, individuals with DS can complete a computerised cognitive training programme. Furthermore, the results were promising with significant improvements found in neuropsychological assessments of executive function. These findings need further investigation with a larger sample size and would benefit from the use of a brain imaging component to strengthen the findings.

Associations between electroencephalography power and Alzheimer's disease in persons with Down syndrome

BACKGROUND

It is complicated to diagnose dementia in persons with Down syndrome (DS). Older studies have, however, demonstrated low-frequency activity in electroencephalography (EEG) in persons with concurrent DS and Alzheimer's disease (DS-AD). The aim of this study was to examine whether it was possible to identify AD-associated changes (increased high-frequency power and decreased low-frequency power) in persons with DS-AD compared with DS.

METHODS

We included 21 persons with DS-AD and 16 with DS without cognitive deterioration assessed by the informant-based Dementia Screening Questionnaire in Intellectual Disability. EEG was recorded for all participants. Absolute power for each electrode and global power were calculated for all frequency bands for both eyes open and eyes closed.

RESULTS

For global power in the eyes closed condition, we found an increased global slow-frequency activity and a decreased global high-frequency activity in DS-AD compared with DS. In addition, we found a significant difference in the global alpha/delta ratio with the largest difference found for global alpha power in DS-AD compared with DS.

CONCLUSIONS

In the current study, we found that changes known to be associated with AD could also be identified when comparing DS-AD with DS using quantitative EEG. In general, these findings suggest that EEG might be a useful tool in diagnosing AD in persons with DS, but larger studies are needed.

Psychosocial experiences of the ageing of middle-aged people with intellectual disabilities in South Korea

This study aims to explore the psychosocial experiences of the ageing of middle-aged people with intellectual disabilities in Korea. Data were collected through 28 face-to-face interviews with Korean individuals with intellectual disabilities, aged between 40 and 50. This study identified several key factors faced by middle-aged people with intellectual disabilities. First, they experience financial constraints due to a lack of economic self-determination. Second, they have a very narrow range of social connections. Typically, they have small and weak networks consisting of only a few social workers, personal assistants, or group home workers, or their peers at group home or workshops. This is often due to a lack of information, money, and age-appropriate services. Third, those who have jobs in middle age have positive opportunities acquired through work. Fourth, study participants experienced considerable unspecified anxiety about ageing, as well as fear of death and uncertainty regarding the future. Recommendations are made to improve active ageing in an appropriate setting for middle-aged people with intellectual disabilities. Improved training and education about economic self-determination are needed for these individuals and their families, as well as improved information about community services. Moreover, enhanced community services for them must be developed. These individuals would benefit from improved employment opportunities as well. Workshops regarding active ageing and death should be developed. Finally, future plans for living placement must be in place.

Living with a disability: a qualitative study of associations between social relations, social participation and quality of life

PURPOSE

We explored which shared aspects of social relations were considered important to the quality of life of persons between the ages of 10 and 40 years living with a disability. We examined how social relations were experienced as affecting quality of life and social participation.

MATERIALS AND METHODS

Fifteen focus groups involving 48 persons with disabilities were conducted using photo elicitation, preference ranking and props. Focus group interviews were supplemented with seven individual interviews with individuals unable to participate in focus groups. All focus group interviews and individual interviews were audiotaped, transcribed, and thematic data analysis was conducted.

RESULTS

We identified caregiving, dependency, and understanding as essential for quality of life. Acceptance from society, discrimination and prejudice, and the ability to participate in society were also highlighted as affecting quality of life. The use of social tactics to avoid confrontation with certain aspects of their disability was common among participants.

CONCLUSIONS

Across disabilities, caregiving, dependency, understanding and acceptance, and discrimination and prejudice were all important aspects for the quality of life of the individuals. Social relations were closely related to social participation, and the latter affected the quality of life of the participants. Social tactics were used to navigate social relations. Implications for rehabilitation We suggest to formalize the concept of social tactics and use it in patient education to enhance quality of life in individuals living with disabilities. People may accept and learn to cope with the impact of their disability, but how they maintain their social participation and social relations also impact on their quality of life. In their assessment, professionals working with individuals with disabilities should, therefore, give more priority to analyze the impact of social relations. When intervening, an effort to establish and maintain social relations should be considered along with psychological help, allocation of aids and economical support aiming to enhance quality of life and social participation among individuals with disabilities. When evaluating efforts to improve quality of life, it is important to investigate whether the intervention has improved the social relations.

Healthy Ageing in People with Intellectual Disabilities from Managers' Perspective: A Qualitative Study

An increasing number of people with intellectual disability (ID) are reaching older ages today although they experience more health problems than the older population without ID. Leaders in intellectual disability services can greatly influence the conditions for a healthy ageing, and the aim of the present study was to explore healthy ageing in this group from the perspective of the leaders. Interviews with 20 leaders were subjected to qualitative content analysis. The findings gave rise to the overall theme ageing in dependence, which emerged from the following six categories: Supporting self-determination; Inaccessible activities after retirement; Signs of decline; Increased and specific needs for support and care; A non-question of gender; Aspects concerning the end of life and death. A prerequisite for healthy ageing in the case of people with ID is, according to the leaders, that they can live the life according to their preferences and make independent choices whilst at the same time receiving adequate support. With the shrinking of their social network after retirement, they become increasingly dependent on staff and leaders in the group home, who need to know what healthy ageing implies.

Physical activity levels in adults with intellectual disabilities: A systematic review

Despite evidence that inactivity is a major factor causing ill health in people with intellectual disabilities (pwID) there are gaps in our knowledge of their physical activity (PA). To date, there is no published systematic review of their PA levels. Therefore, we performed a systematic review from January-October 2015, comprising studies from across the globe to establish PA levels, determine how they were measured, and what factors influenced PA in adults with intellectual disabilities (awID). Five databases were searched. Studies were included if written in English, peer-reviewed, had primary research data, and measured PA levels of awID. Quality was assessed using a 19-item checklist. Meta-summary of the findings was performed and a meta-analysis of factors influencing PA using multiple regression. Fifteen studies were included consisting of 3159 awID, aged 16-81 years, 54% male and 46% female. Only 9% of participants achieved minimum PA guidelines. PA levels were measured using objective and subjective methods. ID severity, living in care, gender, and age were independently significantly correlated with the number of participants achieving PA guidelines with the strongest predictor being ID severity (Beta 0.631, p < 0.001). Findings should be in the context that most of the participants were in the mild/moderate range of ID severity and none of the studies objectively measured PA in people with profound ID. To inform measurement and intervention design for improved PA, we recommend that there is an urgent need for future PA studies in awID population to include all disability severity levels.

Characterising the nature of primary care patient safety incident reports in the England and Wales National Reporting and Learning System: a mixed-methods agenda-setting study for general practice

Background

There is an emerging interest in the inadvertent harm caused to patients by the provision of primary health-care services. To date (up to 2015), there has been limited research interest and few policy directives focused on patient safety in primary care. In 2003, a major investment was made in the National Reporting and Learning System to better understand patient safety incidents occurring in England and Wales. This is now the largest repository of patient safety incidents in the world. Over 40,000 safety incident reports have arisen from general practice. These have never been systematically analysed, and a key challenge to exploiting these data has been the largely unstructured, free-text data.

Aims

To characterise the nature and range of incidents reported from general practice in England and Wales (2005–13) in order to identify the most frequent and most harmful patient safety incidents, and relevant contributory issues, to inform recommendations for improving the safety of primary care provision in key strategic areas.

Methods

We undertook a cross-sectional mixed-methods evaluation of general practice patient safety incident reports. We developed our own classification (coding) system using an iterative approach to describe the incident, contributory factors and incident outcomes. Exploratory data analysis methods with subsequent thematic analysis was undertaken to identify the most harmful and most frequent incident types, and the underlying contributory themes. The study team discussed quantitative and qualitative analyses, and vignette examples, to propose recommendations for practice.

Main findings

We have identified considerable variation in reporting culture across England and Wales between organisations. Two-thirds of all reports did not describe explicit reasons about why an incident occurred. Diagnosis- and assessment-related incidents described the highest proportion of harm to patients; over three-quarters of these reports (79%) described a harmful outcome, and half of the total reports described serious harm or death (n = 366, 50%). Nine hundred and ninety-six reports described serious harm or death of a patient. Four main contributory themes underpinned serious harm- and death-related incidents: (1) communication errors in the referral and discharge of patients; (2) physician decision-making; (3) unfamiliar symptom presentation and inadequate administration delaying cancer diagnoses; and (4) delayed management or mismanagement following failures to recognise signs of clinical (medical, surgical and mental health) deterioration.

Conclusions

Although there are recognised limitations of safety-reporting system data, this study has generated hypotheses, through an inductive process, that now require development and testing through future research and improvement efforts in clinical practice. Cross-cutting priority recommendations include maximising opportunities to learn from patient safety incidents; building information technology infrastructure to enable details of all health-care encounters to be recorded in one system; developing and testing methods to identify and manage vulnerable patients at risk of deterioration, unscheduled hospital admission or readmission following discharge from hospital; and identifying ways patients, parents and carers can help prevent safety incidents. Further work must now involve a wider characterisation of reports contributed by the rest of the primary care disciplines (pharmacy, midwifery, health visiting, nursing and dentistry), include scoping reviews to identify interventions and improvement initiatives that address priority recommendations, and continue to advance the methods used to generate learning from safety reports.

A comparison of reports of caregiver burden between foster family care providers and staff caregivers in other settings

There has been increasing concern about the impact of dementia symptoms on the lives and on the care being provided for persons with intellectual disability (ID) in out-of-home settings. One such setting that has received little attention is foster family care homes. These settings in the USA replicate family living and while some supports and resources are provided, they are not designed to meet intensive care needs. As a preliminary step in understanding family experiences and to expand the range of interest in Alzheimer’s disease (AD) in persons with ID beyond traditional out-of-home settings, a pilot study was initiated that included aging persons with ID and symptoms of AD who were living in foster family care settings in two regions of New York State as well as more traditional out-of-home care subjects. Comparisons of matched samples on subjective and objective burden measures suggest that there are few differences in experiences. The limitations of these findings are considered and recommendations made for future, related research.

Planning ahead

Despite the acknowledged increase in the number of older people with intellectual disabilities (ID) in the UK, the age-related health and social care needs of this population have yet to be fully understood and addressed. Although there is some evidence of positive development, the current picture of service provision is characterized by fragmentation and limited choice of resources and specialist care. Policy aims are variably met and inconsistently applied. Research suggests that service planning is often incoherent, that many older people with ID and their carers receive poor quality non-specialist care and that staff are inadequately trained to manage the often multiple and complex needs of this user group. There is a considerable co-joined service development and research challenge in this emerging field. If older people with ID and their carers are to receive quality provision, a coherent and well-funded service planning system is required which is underpinned by articulated agency partnerships, informed by good practice developments in the fields of ID, gerontology and dementia care, and linked to evidence about effective models of care and services. The incorporation of the perspectives of users and carers in the planning process is an essential pre-requisite as is a commitment to the development of effective support across the life course of all individuals with ID.

A critical literature review of the effectiveness of various instruments in the diagnosis of dementia in adults with intellectual disabilities

Introduction

Currently, there is no consensus on dementia diagnostics in adults with intellectual disabilities (ID). There are three types of assessments available: direct cognitive tests, test batteries, and informant reports.

Methods

A systematic literature search was conducted in four databases yielding 9840 records. Relevant studies were identified and selected using predefined inclusion and exclusion criteria and then coded and classified according to assessment type. This was completed by two independent researchers, with a third consulted when discrepancies arose. The review collates diagnostic instruments and presents strengths and weaknesses.

Results

Overall 47 studies met the search criteria, and 43 instruments were extracted from the selected studies. Of which, 10 instruments were classified as test batteries, 23 were classified as direct cognitive tests, and the remaining 10 were informant reports.

Discussion

This review can recommend that cognitive test batteries can offer the most practical and efficient method for dementia diagnosis in individuals with ID.

Quantitative Electroencephalography as a Diagnostic Tool for Alzheimer's Dementia in Adults with Down Syndrome

Background

Assessment of dementia in individuals with intellectual disability is complex due to great inter-individual variability in cognitive function prior to dementia and a lack of standardized instruments. Studies have indicated that quantitative electroencephalography (qEEG) results may be used as a diagnostic marker for dementia. The aim of this study was to examine the value of qEEG in the diagnostic evaluation of dementia in patients with Down syndrome (DS).

Method

The study included 21 patients with DS and mild-to-moderate dementia due to Alzheimer's disease (DS-AD) and 16 age-matched adults with DS without cognitive deterioration assessed by the informant-based Dementia Screening Questionnaire in Intellectual Disability (DSQIID). Conventional EEG was performed and analysed quantitatively using fast Fourier transformation. Outcomes were centroid frequency, peak frequency, absolute power, and relative power.

Results

In several regions of the brain, a significant decrease in the theta-1 band (4-7 Hz) was identified for the centroid frequency. A significant negative correlation was demonstrated between the mean of the centroid frequency of the theta-1 band and the total DSQIID score.

Conclusion

We found that qEEG can detect a significant decrease in centroid frequency in a sample of patients with DS-AD as compared to a sample of adults with DS and no cognitive deterioration.

Dementia and mild cognitive impairment in adults with intellectual disability: issues of diagnosis

Individuals with intellectual disability (ID) are now living longer with the majority of individuals reaching middle and even "old age." As a consequence of this extended longevity they are vulnerable to the same age-associated health problems as elderly adults in the general population without ID. This includes dementia, a general term referring to a variety of diseases and conditions causing substantial loss of cognitive ability and functional declines; adults with Down syndrome are at especially high risk. A great deal of recent effort has focused on the very earliest detectable indicators of decline (and even prodromal stages of dementia-causing diseases). A condition called mild cognitive impairment (MCI) has been conceptually defined as a decline in functioning that is more severe than expected with typical brain aging but not severe enough to meet criteria for a diagnosis of dementia. Consensus criteria for both dementia and MCI have been developed for typically developing adults but are of limited applicability for adults with ID, given their pre-existing cognitive impairments. Early diagnosis will continue to be of growing importance, both to support symptomatic treatment and to prevent irreversible neuropathology when interventions are developed to slow or halt the progression of underlying disease. While the intellectual and developmental disabilities field has for some time recognized the need to develop best-practices for the diagnosis of MCI and dementia, there remains a pressing need for empirically based assessment methods and classification criteria.

Lived experiences of ageing and later life in older people with intellectual disabilities

The aim of this article is to explore how older people with intellectual disability (ID), who live in group accommodation, describe their lived experience in relation to ageing and later life. The article is based on a study with a phenomenological approach, grounded on the concept of life-world. Individual, qualitative interviews were conducted with 12 people with ID (five men, seven women), between the ages of 48 and 71 (mean=64), who lived in four different group accommodation units in southern Sweden. A descriptive phenomenological analysis method was used, which disclosed a structure consisting of themes and sub-themes. The findings of the study reveal the informants' lived experience of ageing and later life as a multifaceted phenomenon, expressed through the two themes, ‘age as a process of change’ and ‘existential aspects of ageing’, each with three sub-themes. The body is an essential element in their experience of ageing and growing old, and in how this experience is expressed. The study also found social, cultural and historical dimensions of the life-world to be important in the informants' experience of ageing and later life. This supports understanding of the existence of a collective life-world for older people with ID, the unique experiences the informants share because of their disability and its consequences for their lifecourse.

Issues in caregiving for older people with intellectual disabilities and their ageing family carers: a review and commentary

BACKGROUND

In keeping with worldwide demographic changes and an ageing population, people with intellectual disabilities are living longer and all the evidence suggest that this trend will continue. This 'new' population of older people and their carers will pose challenges for health and social care providers.

AIM

This paper presents a review of the literature on key issues influencing caregiving for older people with intellectual disabilities and their ageing family carers.

METHODS

The review was undertaken using a framework adapted from the NHS Centre for Reviews and Dissemination. Papers were identified through the use of databases including CINAHL, Science Direct, PsychoInfo, Blackwell Synergy, the Cochrane Library and MEDLINE.

FINDINGS

The key themes which emerged from the literature and which consequently form the basis of this review include: ageing family carers, future planning and support services. In the context of family caregiving, older people with intellectual disabilities represent a unique group insofar as they are unlikely to be married and therefore have no spouse or dependents to care for them in later life. As a result, parents (usually mothers) have to continue caring for their son or daughter with an intellectual disability as they both grow older, often resulting in a mutually dependent relationship. The caregiving situation is further complicated by poor emergency and future planning and by a lack of appropriate services for this group of individuals.

CONCLUSIONS

In light of the emergence of a 'new' population of older people with intellectual disabilities, there is an urgent need to develop services and support structures which will enable these individuals and their ageing carers to 'age in place' and when this is no longer possible, to have appropriate alternatives that recognise the duality of their needs as older people and as people with intellectual disabilities.

IMPLICATIONS FOR PRACTICE

Opportunities for supervision could be one way to increase individuals' awareness of their own role in the team.

Health of ageing people with intellectual disability and the role of the nurse in Ireland

The number of people with intellectual disability living into old age continues to increase. As one ages, generally, functional ability decreases and health issues increase, with recognising and responding to the health needs of the person with intellectual disability of great importance and the responsibility of the intellectual disability nurse. The nurse must review and adjust the way they deliver care to ageing people with intellectual disability, not only in terms of responding to their health needs but also through collaborative working within teams and other services. As Ireland has specifically trained nurses in intellectual disability, it has a prime opportunity to address the health needs and concerns of people with intdisability and actively advocate for how services develop and responds to the changing health needs of ageing people with intellectual disability.

[Aging and quality of life: challenges and opportunities for people with intellectual disabilities]

In the coming years, a growing number of people with an intellectual disability will reach retirement age. In line with the change of paradigms, the leading ideas of participation, inclusion and self-determination have become the principles of the ideological and conceptual framework in social services for people with disabilities. However, in many places convincing concepts and arrangements of support for elderly people with intellectual disabilities are lacking, particularly beyond institutionalized concepts. The research project "Lebensqualität inklusiv(e)" (quality of life included) tries to bridge this gap. On the base of an estimation of the demographic development for this group of people, models of best practice have been documented and evaluated focusing on living conditions and the special requirements for elderly people with intellectual disabilities in order to gather ideas for the development of arrangements of support. The results show that an interdisciplinary cooperation is indispensable.

The role of nurses in meeting the health care needs of older people with intellectual disabilities: a review of the published literature

People with intellectual disabilities are now living longer and as a consequence are likely to have greater physical and mental health needs compared to the general population. Nurses may have a crucial role to play in meeting such needs, although it is unclear whether nurses are prepared for this role. This review of the available literature found little evidence of nurses undertaking effective interventions in meeting the health needs of older people with intellectual disabilities in the UK and Ireland. Nurses have been alerted to the increase in numbers of older people with intellectual disabilities and offered some direction on their future role in this area. Most of the available literature is based mainly on informed opinion rather than research findings.

Hospitalisation rates for ambulatory care sensitive conditions for persons with and without an intellectual disability--a population perspective

BACKGROUND

There is evidence that persons with an intellectual disability (ID) face barriers to primary care; however, this has not been extensively studied at the population level. Rates of hospitalisation for ambulatory care sensitive conditions are used as an indicator of access to, and quality of, primary care. The objective of the study was to compare hospitalisation rates for ambulatory care sensitive conditions between persons with and without an ID in a publicly insured population.

METHODS

Persons with an ID were identified among the general population of a Canadian province between 1999 and 2003. Using a list of conditions applicable to persons with an ID, rates of hospitalisations for ambulatory care sensitive conditions for persons with and without an ID were calculated and compared. Regression models were used to adjust for age, sex and place of residence. Hospitalisation rates for specific conditions were also compared, controlling for differences in disease prevalence where possible.

RESULTS

Persons with an ID were consistently hospitalised for ambulatory care sensitive conditions at a higher rate than persons without an ID. Between 1999 and 2003 the adjusted rate ratio (RR) was 6.1 [95% confidence interval (CI) = 5.6, 6.7]. Rate ratios were highest when comparing persons with, to persons without, an ID between the ages of 30-39 (RR = 13.1; 95% CI = 10.6, 16.2) and among urban area dwellers (RR = 7.0; 95% CI = 6.2, 7.9). Hospitalisation rates for epilepsy and schizophrenic disorders were, respectively, 54 and 15 times higher for persons with compared with persons without an ID. Rate ratios for diabetes and asthma remained significant after controlling for the population prevalence of these diseases.

CONCLUSIONS

The large discrepancy in rates of hospitalisation between persons with and without an ID is an indicator of inadequate primary care for this vulnerable population. Decreasing the number of ambulatory care sensitive condition hospitalisations through specialised outpatient programmes for persons with an ID would potentially lead to better health, improved quality of life and cost savings. Future research should include potentially important factors such as disease severity, socio-economic variables and measures of health service organisation in the analysis. International comparisons of ambulatory care sensitive condition hospitalisation rates could point to the benefits and limitations of the health service policy directions adopted by different countries.

Bridging policies and practice: challenges and opportunities for the governance of disability and ageing

Introduction

In the context of an increasingly ageing society with a growing number of persons diagnosed with chronic disabling conditions including dementia and persons with disabilities, ageing and disability represent two policy fields which need to be jointly re-thought. So far, policymakers and other political actors have not adequately reacted to these changing demographics.

Description of policy and practice

The two policy fields are based upon different presuppositions. Also, disability and ageing interest groups set different agendas. As several political actor groups with diverse interests and goals operate in the political space, efforts to bridge policies and practices in ageing and disability are confronted with several challenges.

Conclusion and discussion

In order to create a policy framework for disability and ageing, shared political priorities need to be developed. It is necessary to re-think current disability and ageing policies and the objectives formulated by diverse interest groups in both fields, and future policies should not only focus on ‘active/healthy/normal ageing’ vs. ‘non-healthy/non-normal ageing’. Overlap of contents between disability and ageing policies exists with both fields informing one another. This mutual influence will shape policymaking and policy practices with regard to an ageing population with a growing number of persons with disabilities.

Service use and cost of mental disorder in older adults with intellectual disability

BACKGROUND

The cost of caring for people with intellectual disability currently makes up a large proportion of healthcare spending in western Europe, and may rise in line with the increasing numbers of people with intellectual disability now living to old age.

AIMS

To report service use and costs of older people with intellectual disability and explore the influence of sociodemographic and illness-related determinants.

METHOD

We collected data on receipt and costs of accommodation, health and personal care, physical as well as mental illness, dementia, sensory impairment and disability in a representative sample of adults with intellectual disability aged 60 years and older (n = 212).

RESULTS

The average weekly cost in GBP per older person was 790 pounds (41,080 pounds per year). Accommodation accounted for 74%. Overall costs were highest for those living in congregate settings. Gender, intellectual disability severity, hearing impairment, physical disorder and mental illness had significant independent relationships with costs. Mental illness was associated with an additional weekly cost of 202 pounds.

CONCLUSIONS

Older adults with intellectual disability comprise about 0.15-0.25% of the population of England but consume up to 5% of the total personal care budget. Interventions that meet needs and might prove to be cost-effective should be sought.

The impact of aging on eating, drinking, and swallowing function in people with Down's syndrome

Many people with Down's syndrome (DS) experience eating, drinking, and swallowing (EDS) difficulties, which can potentially lead to life-threatening conditions such as malnutrition, dehydration, and aspiration pneumonia. As the life expectancy of people with DS continues to improve, there is an increasing need to examine how the aging process may further affect these conditions. Published research studies have yet to address this issue; therefore, this article draws on the literature in three associated areas in order to consider the dysphagic problems that might develop in aging people with DS. The areas examined are EDS development in children and adolescents with DS, EDS changes associated with aging, and EDS changes associated with dementia of the Alzheimer's type (DAT) because this condition is prevalent in older adults with DS. This article concludes that unlike in the general population, the aging process is likely to cause dysphagic difficulties in people with DS as they get older. Therefore, it is suggested that longitudinal studies are needed to examine the specific aspects of EDS function that may be affected by aging and concomitant conditions in DS.

Mortality in adults with moderate to profound intellectual disability: a population-based study

BACKGROUND

People with intellectual disability (ID) experience a variety of health inequalities compared with the general population including higher mortality rates. This is the first UK population-based study to measure the extent of excess mortality in people with ID compared with the general population.

METHOD

Indirectly standardized all-cause and disease mortality ratios (SMRs) and exact Poisson confidence intervals were calculated by age and sex for all adults, aged 20 years or over, with moderate to profound ID living in Leicestershire and Rutland, UK, between 1993 and 2005. The general population of Leicestershire and Rutland, which has a population of approximately 700,000 individuals in this age range, was used for comparison. To explore differences within the study population, overall SMRs were also calculated by presence of Down syndrome and last place of residence (city or county).

RESULTS

Of 2436 adults identified, 409 (17%) died during 23,000 person-years of follow-up. Both all-cause and disease-specific mortality were around three times higher than the general population but varied considerably with age. The largest differences were observed in people in their twenties, where all-cause mortality was almost nine times higher in men (SMR=883; 95% CI=560-1325) and more than 17 times higher in women (SMR=1722; 95% CI=964-2840). At a particular disadvantage were people with Down syndrome and women with ID living in the city.

CONCLUSIONS

The relatively high SMRs observed in young people and in women, particularly those living in inner city areas and with Down syndrome, deserve further investigation for possible explanations, including socio-economic factors.

Fifteen-year follow-up of 92 hospitalized adults with Down's syndrome: incidence of cognitive decline, its relationship to age and neuropathology

BACKGROUND

The clinical and neuropathological features associated with dementia in Down's syndrome (DS) are not well established. Aims To examine clinico-pathological correlations and the incidence of cognitive decline in a cohort of adults with DS.

METHOD

A total of 92 hospitalized persons with DS were followed up from 1985 to December 2000. At outset, 87 participants were dementia-free, with a median age of 38 years. Assessments included the Prudhoe Cognitive Function Test (PCFT) and the Adaptive Behavior Scale (ABS), to measure cognitive and behavioural deterioration. Dementia was diagnosed from case records and caregivers' reports.

RESULTS

Eighteen (21%) patients developed dementia during follow-up, with a median age of onset 55.5 years (range 45-74). The PCFT demonstrated cognitive decline among those with a less severe intellectual disability (mild and moderate) but not among the profoundly disabled people (severe and profound). Clinical dementia was associated with neuropathological features of Alzheimer's disease, and correlated with neocortical neurofibrillary tangle densities. At the age of 60 years and above, a little more than 50% of patients still alive had clinical evidence of dementia.

CONCLUSIONS

Clinical dementia associated with measurable cognitive and functional decline is frequent in people with DS after middle age, and can be readily diagnosed among less severely intellectually disabled persons using measures of cognitive function such as the PCFT and behavioural scales such as the ABS. In the more profoundly disabled people, the diagnosis of dementia is facilitated by the use of behavioural and neurological criteria. In this study, the largest prospective DS series including neuropathology on deceased patients, the density of neurofibrillary tangles related more closely to the dementia of DS than senile plaques. In people with DS surviving to middle and old age, the development of dementia of Alzheimer type is frequent but not inevitable, and some people with DS reach old age without clinical features of dementia.

Assessing dementia in people with learning disabilities: the relationship between two screening measures

As life expectancy increases for people with learning disabilities, the impact of dementia on people with learning disabilities and their families, carers and services is becoming more apparent. Psychological services for learning disabilities are receiving an increasing number of referrals requesting dementia assessment. Health and social care services are adapting to the diverse needs of an ageing population with learning disabilities. This article describes a study investigating the relationship between two assessments for dementia in people with learning disabilities. Carers of people with learning disabilities over the age of 50 (or 40 if the individual had Down syndrome) completed the Dementia Questionnaire for Mentally Retarded People and the Adaptive Behaviour Scale--Residential and Community. Overall, the two questionnaire measures showed significant relationships. However, results suggested that both assessments have clinical value in informing individual needs and aiding diagnosis. Implications for both clinical and social care services are discussed.

Age at death of people with an intellectual disability in Ireland

This study examined the age at death of people with an intellectual disability in Ireland. Using data from the National Intellectual Disability Database, the average age at death of 1120 people who died between 1996 and 2001 was 45.68 years, with no difference in lifespan between men and women. A more severe level of intellectual disability predicted shorter lifespan. In general, those requiring lower levels of day-to-day support and supervision had a longer lifespan. Those living in the family home had the shortest lifespan while those in hospital residential environments had the longest lifespan. Those not attending any day service had a longer lifespan than those attending a range of day services. There were also differences in age at death across different health board regions. These findings are discussed in light of their implications for service planning.

A long-term population-based clinical and morbidity profile of Angelman syndrome in Western Australia: 1953-2003

PURPOSE

To investigate the incidence, clinical presentation and associated comorbidities of Angelman syndrome (AS) in Western Australia, with establishment of an information database for the disorder.

METHODS

Data were collected from Disability Services Commission files, supplemented by datasets provided by the Western Australian Data Linkage Unit. The analysis was retrospective and quantitative.

RESULTS

Thirty-four individuals (two deceased) were identified (19 F, 15 M), with a mean age of 21.6 years; 52.9% had an IQ < 40, with the remainder of IQ 40-69. The incidence was one in 40,000 births and mean age at diagnosis was 5.8 years. The mean age of the 23 home residents was 20.2 years compared to 27.9 years in the nine individuals in sheltered accommodation. In general, the patients exhibited a typical AS clinical presentation. A median of 5.5 (range 0-20) hospital admissions was recorded per person, with epilepsy, gastrointestinal disorders, and dental work all common reasons for admission.

CONCLUSIONS

The estimated incidence was low compared to other reports, as was the proportion of IQ < 40. AS cases required substantial levels of medical care, especially those who were epileptic. An increase in the future numbers of AS patients needing sheltered accommodation is predicted.

Cognitive behaviour therapy and people with learning disabilities: implications for developing nursing practice

People with learning disabilities are an ageing and increasing population and have been the subject of policy initiatives by the four countries of the UK, detailing the range of supports that need to be in place for this group. The evidence base of their mental health needs is growing and with it the need to ensure the full range of psychotherapies available to the general population are made available to people with learning disabilities. Cognitive Behaviour Therapy (CBT) is now a widely accepted and effective form of psychotherapy for many mental health problems and the evidence base is growing on the effectiveness with the learning disability population; however, the model needs to be applied differently for this group to take account of their cognitive impairment and support needs. Registered Nurses in Learning Disabilities are well placed to apply this approach within their clinical practice; however, there is an absence of leadership and direction in the development of CBT for this group of clinicians. There is a need to support education and practice development to contribute to addressing the emotional needs of people with learning disabilities. Action is required to support education to prepare Registered Nurses in Learning Disabilities to practice CBT and to contribute to the ongoing development of research in this area of clinical practice.

Economic implications of current and future provision of English learning disability health services

People with learning disabilities represent approximately 2.3% of the population. Levels of physical disability, sensory impairment and mental health difficulties provide enormous challenges to the health and social services responsible for their care. Following political initiatives, such as Valuing People, statutory frameworks implementing care standards and changes to the Mental Health Act, as well as economic implications, are significant. Pharmacotherapy for the projected treatment of Alzheimer's dementia in Down's syndrome will require major investment. There is a disproportionate impact on rural services as an urban/rural divide grows in the residential care services. Increasing movement of specialist provision from the National Health Service to the private sector, with recruitment and retention issues pulling clinicians in the same direction, is slowly changing the economics of learning disability services as we know them.

Behavioural symptoms among people with severe and profound intellectual disabilities: a 26-year follow-up study

BACKGROUND

Very little is known about the natural history of challenging behaviour and psychiatric disorder in people with severe and profound degrees of intellectual disability.

AIMS

To clarify the natural history of challenging behaviour and psychiatric disorder in this population through a longterm prospective cohort study over a 26-year period.

METHOD

One hundred individuals with severe or profound intellectual disability were randomly selected in 1975. Their behaviour was recorded through carer and psychiatrist ratings using the Modified Manifest Abnormality Scale of the Clinical Interview Schedule. The presence and severity of psychiatric disorder were also recorded. The study was repeated in 1981/82 and 1992/93. We repeated the study again in 2001, supplementing the original observational data with the Checklist of Challenging Behaviour.

RESULTS

Behavioural symptomatology is remarkably persistent, particularly stereotypy, emotional abnormalities, eye avoidance and overactivity, although the severity of overall psychiatric disorder does show some abatement through time.

CONCLUSIONS

These findings influence the prospects of success in relocating adults with severe and profound degrees of intellectual disability back into the community.

Costs of village community, residential campus and dispersed housing provision for people with intellectual disability

BACKGROUND

In recent years, a growing volume of research evidence has been generated about the relative cost-effectiveness of various types of community-based residential supports for people with intellectual disability (ID) in the UK. However, few reliable data are available to inform planners, commissioners or service providers about the quality and costs of providing support within residential or village communities.

METHODS

The evaluation described in the present paper aimed to fill some of the gaps in knowledge by examining the comparative costs of supporting people in village community settings, in National Health Service (NHS) residential campuses and in dispersed, community-based housing schemes. The complete service package received by each study participant was described and costed, and a series of statistical analyses was undertaken to identify factors associated with variations in the cost of support. The analyses reported in the present paper were based on comparisons of 86 people living in village communities, 133 in residential campuses and 281 in dispersed housing schemes.

RESULTS

Wide variations in cost were found, not only between models of accommodation, but between individual organizations, settings and service users. Multivariate analysis revealed that higher costs were associated with supports for people with higher levels of ID and more severe challenging behaviour. The cost of support was affected by the size of the residential setting, with smaller facilities likely to be more expensive. Associations were also found between increased costs, and services for younger users, male users and people who had not moved from a NHS hospital. Generally, more sophisticated service processes within the setting were associated with higher costs; although systematic arrangements for supervision and training of staff had a negative effect on cost.

CONCLUSIONS

The cost findings should be considered alongside evidence on outcomes. A comparison of village communities and dispersed housing schemes suggests that both models of provision appear be associated with particular benefits, although different types of setting are appropriate for different individuals and therefore, the continued development of a range of residential models is important.

Long-term affective disorder in people with mild learning disability

BACKGROUND

Increased risk of affective disorder in learning disability has been reported, although the extent to which this is due to adverse social and material circumstances is uncertain and there have been potential limitations in the measurement of affective disorder.

AIMS

To determine risk of affective disorder in those classified with mild learning disability in the British 1946 birth cohort and to investigate whether this risk was accounted for by disadvantage in childhood and adulthood.

METHOD

Learning disability was defined as the equivalent of an IQ < or =69 at age 15 years. The Present State Examination at age 36 years and the Psychiatric Symptom Frequency Scale at age 43 years provided psychiatric outcome measures.

RESULTS

Learning disability was associated with a fourfold increase in risk of affective disorder, not accounted for by social and material disadvantage or by medical disorder.

CONCLUSIONS

Learning disability is strongly associated with risk of affective disorder, persisting well into midlife.

Intra-amygdala spermidine administration improves inhibitory avoidance performance in rats

In the present study, we investigated the effect of immediate post-training bilateral infusion of spermidine, a polyamine agonist, into the amygdala on inhibitory avoidance learning of rats. Bilateral microinjection of spermidine (0.02--20 nmol) caused an increase in test step-down latencies at high concentrations. Administration of arcaine (0.002--0.2 nmol), an antagonist of the NMDA receptor polyamine binding site, decreased test step-down latencies. On the other hand, co-administration of arcaine and spermidine completely reversed the spermidine-induced increase of test step-down latencies. These results provide evidence that polyamines may be involved in learning and memory modulation in the amygdala.

The needs of older people with learning disabilities

There has been a growing realization that the needs of older people with learning disabilities are not being met. There has been little attention paid in nursing literature to the needs of this client group. This article will explore the issues about older people with learning disabilities and highlight some of the important areas that learning disability nurses may need to address. It is evident that there needs to be more collaboration between a range of different services and professionals. Areas of good practice can be used in developing innovative and flexible services, which are client led. Learning disability nurses may need to update their skills and knowledge and develop a 'critical practice' approach to meet the many challenges that older people with learning disabilities may pose.
