Signs in People with Intellectual Disabilities: Interviews with Managers and Staff on the Identification Process of Dementia

Experiences of people with intellectual disability and dementia: A systematic review

BACKGROUND

Dementia disproportionately affects people with intellectual disability. Most qualitative studies explore their experiences by utilising proxy-reports. A smaller number of studies illustrate the possibility of exploring perspectives directly from people with intellectual disability and dementia.

METHOD

This systematic review synthesised findings from existing studies (n = 8) that involve people with intellectual disability and dementia as participants to understand their experiences of dementia. Searches were conducted using CINAHL, PsychInfo and Social Services Abstracts.

RESULTS

Findings include descriptions of changes in individual functioning, a narrowing of social worlds and of how people made sense of the changes despite often having no knowledge of their dementia diagnosis. Additionally, discussion focuses on how people's experiences are shaped by their environments.

CONCLUSION

The review recognises the complexities of speaking to people with intellectual disability about dementia, challenges views that people with intellectual and dementia cannot be involved in research and makes recommendations to support inclusion in future studies.

Community-Based Support and Social Services and Their Association with Frailty Factors in Older People with Intellectual Disability and Affective and Anxiety Disorders: A Swedish National Population-Based Register Study

Affective and anxiety diagnoses are common in older people with intellectual disability (ID). The aim was to describe support and social services for older people with ID and affective and/or anxiety diagnoses, also to investigate in this study group the association between support and social services and frailty factors in terms of specialist healthcare utilisation, multimorbidity, polypharmacy, level of ID and behavioural impairment. Data was selected from four population-based Swedish national registries, on 871 identified persons with affective and/or anxiety diagnoses and ID. Multivariate regression analysis was used to investigate associations between frailty factors during 2002-2012 and social services in 2012. People with multimorbidity who frequently utilised specialist healthcare were less likely to utilise residential arrangements. Those with polypharmacy were more likely utilise residential arrangements, and receive personal contact. People with moderate, severe/profound levels of ID were more likely to utilise residential arrangements and to pursue daily activities.

Healthcare utilisation patterns among older people with intellectual disability and with affective and anxiety diagnoses in comparison with the general population

OBJECTIVES

This study investigates specialist healthcare visits of older people with intellectual disability ID having affective and anxiety diagnoses in comparison with the general population, as well as across different levels of ID, behavioural impairment, and living in special housing in Sweden.

METHOD

The study is a retrospective national-register-based study from 2002-2012 of people with ID 55 years and older (n = 7936) and a control group the same size matched by birth year and sex from the general population at the end of study. The study groups comprised those with affective (n = 918) and anxiety (n = 825) diagnoses who visited specialist healthcare, including data about living in special housing at the end of study in 2012.

RESULTS

Older people with ID and with affective and anxiety diagnoses have a higher risk of inpatient and unplanned visits to psychiatric and somatic healthcare than the general population. The average length of stay in inpatient psychiatric healthcare was higher in older people with ID and anxiety diagnoses than in the general population. Within the ID group, more inpatient and unplanned visits were made by those with moderate and severe levels of ID, behavioural impairment, and living in special housing.

CONCLUSION

Older people with ID and affective and anxiety diagnoses are more likely to have inpatient and unplanned visits for specialist healthcare than the general population. Future research should explore the quality of healthcare services delivered by healthcare providers to older people with ID and with affective and anxiety diagnoses.

The AT(N) framework for Alzheimer's disease in adults with Down syndrome

The National Institute on Aging in conjunction with the Alzheimer's Association (NIA-AA) recently proposed a biological framework for defining the Alzheimer's disease (AD) continuum. This new framework is based upon the key AD biomarkers (amyloid, tau, neurodegeneration, AT[N]) instead of clinical symptoms and represents the latest understanding that the pathological processes underlying AD begin decades before the manifestation of symptoms. By using these same biomarkers, individuals with Down syndrome (DS), who are genetically predisposed to developing AD, can also be placed more precisely along the AD continuum. The A/T(N) framework is therefore thought to provide an objective manner by which to select and enrich samples for clinical trials. This new framework is highly flexible and allows the addition of newly confirmed AD biomarkers into the existing AT(N) groups. As biomarkers for other pathological processes are validated, they can also be added to the AT(N) classification scheme, which will allow for better characterization and staging of AD in DS. These biological classifications can then be merged with clinical staging for an examination of factors that impact the biological and clinical progression of the disease. Here, we leverage previously published guidelines for the AT(N) framework to generate such a plan for AD among adults with DS.

Health care utilisation among older people with Down syndrome compared to specific medical guidelines for health surveillance: a Swedish national register study

Background

Specific medical guidelines for health surveillance exist for people with Down syndrome (DS) since 25 years but knowledge of adherence to the guidelines is lacking. The guidelines were developed to avoid unnecessary suffering from preventable conditions. The aims of the study were to investigate 1) planned health care visits in relation to the co-morbidities described in specific medical guidelines as a measure of adherence, 2) unplanned health care visits as a measure of potentially unmet health care needs and 3) gender differences in health care utilisation among older people with DS.

Methods

This register-based study includes people with DS (n = 472) from a Swedish national cohort of people with intellectual disability (n = 7936), aged 55 years or more, and with at least one support according to the disability law, in 2012. Data on inpatient and outpatient specialist health care utilisation were collected from the National Patient Register for 2002–2012.

Results

A total of 3854 inpatient and outpatient specialist health care visits were recorded during the 11 years, of which 54.6% (n = 2103) were planned, 44.0% (n = 1695) unplanned and 1.4% (n = 56) lacked information. More than half of the visits, 67.0% (n = 2582) were outpatient health care thus inpatient 33% (n = 1272). Most planned visits (29.4%, n = 618) were to an ophthalmology clinic, and most unplanned visits to an internal medicine clinic (36.6%, n = 621). The most common cause for planned visits was cataract, found at least once for 32.8% in this cohort, followed by arthrosis (8.9%), epilepsy (8.9%) and dementia (6.6%). Pneumonia, pain, fractures and epilepsy each accounted for at least one unplanned visit for approximately one-fourth of the population (27.1, 26.9, 26.3 and 19.7% respectively). Men and women had similar numbers of unplanned visits. However, women were more likely to have visits for epilepsy or fractures, and men more likely for pneumonia.

Conclusions

Increased awareness of existing specific medical guidelines for people with DS is vital for preventive measures. The relatively few planned health care visits according to the medical guidelines together with a high number of unplanned visits caused by conditions which potentially can be prevented suggest a need of improved adherence to medical guidelines.

Use of dementia care mapping in the care for older people with intellectual disabilities: A mixed-method study

Background

The ageing of people with intellectual disabilities, with associated morbidity like dementia, calls for new types of care. Person‐centred methods may support care staff in providing this, an example being Dementia Care Mapping (DCM). DCM has been shown to be feasible in ID‐care. We examined the experiences of ID‐professionals in using DCM.

Methods

We performed a mixed‐methods study, using quantitative data from care staff (N = 136) and qualitative data (focus‐groups, individual interviews) from care staff, group home managers and DCM‐in‐intellectual disabilities mappers (N = 53).

Results

DCM provided new insights into the behaviours of clients, enabled professional reflection and gave new knowledge and skills regarding dementia and person‐centred care. Appreciation of DCM further increased after the second cycle of application.

Conclusion

DCM is perceived as valuable in ID‐care. Further assessment is needed of its effectiveness in ID‐care with respect to quality of care, staff‐client interactions and job performance.

The occurrence of comorbidities with affective and anxiety disorders among older people with intellectual disability compared with the general population: a register study

BACKGROUND

Little is known regarding the burden of comorbidities among older people with intellectual disability (ID) who have affective and anxiety disorders. Therefore, we aimed to investigate the occurrence and risk of psychiatric and somatic comorbidities with affective and/or anxiety disorders in older people with ID compared to the general population.

METHODS

This population study was based on three Swedish national registers over 11 years (2002-2012). The ID group was identified in the LSS register, which comprises of data on measures in accordance with the Act Concerning Support and Service for Persons with Certain Functional Impairments (n = 7936), and a same-sized reference cohort from the Total Population Register was matched by sex and year of birth. The study groups consisted of those with affective (n = 918) and anxiety (n = 825) disorder diagnoses. The information about diagnoses were collected from the National Patient Register based on ICD-10 codes.

RESULTS

The rate of psychiatric comorbidities with affective and anxiety disorders was approximately 11 times higher for people with ID compared to the general reference group. The two most common psychiatric comorbidities occurred with affective and anxiety disorders were Unspecified non-organic psychosis and Other mental disorders due to brain damage and dysfunction and to physical disease (8% for each with affective disorders and 7 and 6% with anxiety disorders, respectively). In contrast, somatic comorbidity comparisons showed that the general reference group was 20% less likely than the ID cohort to have comorbid somatic diagnoses. The most commonly occurring somatic comorbidities were Injury, poisoning and certain other consequences of external causes (49 and 47% with affective and anxiety disorders, respectively) and Signs and symptoms and abnormal clinical and laboratory findings not elsewhere classified (44 and 50% with affective and anxiety disorders, respectively).

CONCLUSION

Older people with ID and with affective and anxiety diagnoses are more likely to be diagnosed with psychiatric comorbidities that are unspecified, which reflects the difficulty of diagnosis, and there is a need for further research to understand this vulnerable group. The low occurrence rate of somatic diagnoses may be a result of those conditions being overshadowed by the high degree of psychiatric comorbidities.
