Dementia-friendly public toilets

Many older adults avoid travelling and social interaction because of the scarcity of public toilets or their inaccessibility. Furthermore, where public toilets are provided, poor design and signage can preclude independent use, particularly for people living with dementia | The Lancet

In general, there is a gap between current public toilet provision and toilet design appropriate for individuals living with dementia, who might have behavioural change, poor level of motivation, loss of mobility and manual dexterity, or abnormalities in visual information processing. In response to research and anecdotal evidence, many guidelines are available to inform and improve the design and independent usability of toilet facilities for people living with dementia. Examples include the use of familiar or automatic flush systems, non-reflective surfaces, good lighting, contrast between doors and surroundings and between the toilet and toilet seat, sinks that do not resemble urinals, well labelled taps and soap dispensers, and the careful placing of mirrors.

However, as highlighted by a substantial amount of anecdotal evidence, the absence of simple and clear way-out signs negates any positive influence of a well designed toilet facility. Such an omission can result in distress, anxiety, embarrassment, and reluctance to use the toilet in the future. Common examples reported to investigators include instances of people having to enter opposite sex toilet facilities to guide their partners out, or going through the wrong door and into undesired or incorrect locations. A fire exit sign showing someone running with a directional arrow is also easily misunderstood as an exit sign, which can result in misdirection with people ending up outside the building and, in some cases, wandering on to a road. Similarly, doors that are both a fire exit and the route back to a public area can cause confusion, and might elicit a reluctance to open them, primarily because of the fear of setting off a fire alarm.

Less REM sleep tied to greater risk of dementia

People who get less rapid eye movement (REM) sleep may have a greater risk of developing dementia, according to a new study. REM sleep is the sleep stage when dreaming occurs. | Neurology | ScienceDaily

People who get less rapid eye movement (REM) sleep may have a greater risk of developing dementia, according to a new study published in the August online issue of Neurology.

There are five stages of sleep. Stage one is light sleep. Stage two is when the body begins to prepare for deeper sleep, including stages three and four. Stage five is REM sleep. During this dream stage, the eyes move rapidly and there is increased brain activity as well as higher body temperature, quicker pulse and faster breathing. The first REM stage occurs about an hour to an hour-and-a-half into sleep and then recurs multiple times throughout the night as the cycles repeat.

The study looked at 321 people with an average age of 67 who participated in The Framingham Heart Study. During that study, sleep cycles were measured for each participant. Researchers collected the sleep data and then followed participants for an average of 12 years. During that time, 32 people were diagnosed with some form of dementia and of those, 24 were determined to have Alzheimer’s disease.

The people who developed dementia spent an average of 17 percent of their sleep time in REM sleep, compared to 20 percent for those who did not develop dementia. After adjusting for age and sex, researchers found links between both a lower percentage of REM sleep and a longer time to get to the REM sleep stage and a greater risk of dementia. For every percent reduction in REM sleep there was a 9 percent increase in the risk of dementia. The results were similar after researchers adjusted for other factors that could affect dementia risk or sleep, such as heart disease factors, depression symptoms and medication use.

Introduction: The end of life for someone with dementia can present several challenges for practitioners. Challenges may be eased with the use of heuristics (rules-of-thumb). For example, FAST is used in stroke: Facial-weakness, Arm-weakness, Slurred-speech, Time to call 999.

Methods: A co-design approach with three phases:

  1.  Focus groups and semi-structured interviews with family carers and practitioners, to identify key decisions and how these should be made. Results were presented to a co-design group consisting of health and care practitioners, and family carers tasked with developing a toolkit of heuristics, through workshops.
  2. Testing the heuristics in practice for six-months in five clinical and care settings.
  3. Evaluation of heuristics through interviews and questionnaires at three and six-months.

Results: Four sets of heuristics were developed, covering; eating/swallowing difficulties, agitation/restlessness, reviewing treatment, and routine care. The heuristics are arranged as flowcharts. Eating/swallowing difficulties have two rules; ensuring eating/swallowing difficulties do not come as a surprise and reflection about ‘comfort-feeding’ only. Agitation/restlessness encourages a holistic approach, considering the environment, physical causes, and caregivers’ health/wellbeing. Reviewing treatment/interventions prompts practitioners to consider the benefits to quality-of-life and comfort. Finally, routine care, such as bathing, prompts practitioners to ensure care interventions improve or do not harm quality-of-life.

Conclusions: Practitioners liked the simplicity of the heuristics, making their implicit knowledge explicit, enhancing their confidence in making decisions at the end of life.

Effectiveness of dementia risk reduction messaging in NHS health checks.

NHS health check 40-64 dementia pilot research findings | Alzheimer’s Society

10774-2

The NHS Health Check programme is a statutory public health intervention commissioned by all local authorities in England. It aims to improve the health and wellbeing of adults aged 40-74 years through the promotion of earlier awareness, assessment, and management of the major risks factors and conditions driving premature death, disability and health inequalities in England.

The overall aim of the research was to evaluate the pilot and assess the feasibility of extending the NHS Health Check for 40-64 year olds to include a dementia risk reduction component. Specific objectives of the research included first, to understand the impact of the NHS Health Check on an individual’s knowledge and awareness of dementia risk reduction and the impact of the intervention on individuals’ intention to change behaviour.

The second objective was to identify (where sample sizes allowed) whether any differences in the delivery of the intervention between pilot sites had any effect on individual’s awareness and understanding of dementia risk reduction.

The third objective was to understand professional awareness and confidence in promoting dementia risk reduction messages and to identify further training requirements, resources and support.

The final objective was to assess any implications for services and commissioners and provide PHE with advice on any further longer-term evaluation that will be required.

Is use of the internet in midlife associated with lower dementia incidence?

Study suggests that use of internet by individuals aged 50 years or older is associated with a reduced risk of dementia

student-849825_1920

Objectives: Dementia is expected to affect one million individuals in the United Kingdom by 2025; its prodromal phase may start decades before its clinical onset. The aim of this study is to investigate whether use of internet from 50 years of age is associated with a lower incidence of dementia over a ten-year follow-up.

Methods: We analysed data based on 8,238 dementia free (at baseline in 2002–2004) core participants from the English Longitudinal Study of Ageing. Information on baseline use of internet was obtained through questionnaires; dementia casesness was based on participant (or informant) reported physician diagnosed dementia or overall score on the Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE). Cox proportional hazards regression analysis was used for examining the relationship between internet use and incident dementia.

Results: There were 301 (5.01%) incident dementia cases during the follow-up. After full multivariable adjustment for potential confounding factors, baseline internet use was associated with a 40% reduction in dementia risk assessed between 2006–2012 (HR = 0.60 CI: 0.42–0.85; p < 0.05).

Conclusion: This study suggests that use of internet by individuals aged 50 years or older is associated with a reduced risk of dementia. Additional studies are needed to better understand the potential causal mechanisms underlying this association.

Dementia can have significant detrimental impacts on the well-being of those with the disease and their carers. A range of computer-based interventions, including touchscreen-based interventions have been researched for use with this population in the hope that they might improve psychological well-being.

The data bases, PsycInfo, ASSIA, Medline, CINAHL, and Cochrane Reviews were searched for touchscreen-based interventions designed to be used by PWD with reported psychological well-being outcomes. Methodological quality was assessed using Pluye and Hong’s (2014) Mixed Methods Appraisal Tool (MMAT) checklist.

Sixteen papers were eligible. They covered 14 methodologically diverse interventions. Interventions were reported to be beneficial in relation to mental health, social interaction, and sense of mastery. Touchscreen interventions also reportedly benefit informal carers in relation to their perceived burden and the quality of their relationships with the people they care for. Key aspects included the user interface, provision of support, learning style, tailored content, appropriate challenge, ergonomics, and users’ dementia progression.

Whilst much of the existing research is relatively small-scale, the findings tentatively suggest that touchscreen-based interventions can improve the psychological well-being of PWD, and possibilities for more rigorous future research are suggested.

They are among the earliest signs and symptoms of neurocognitive disorders and incipient cognitive decline, yet are under-recognized and often challenging to treat. With this in mind, the Alzheimer’s Association convened a Research Roundtable in May 2016, bringing together experts from academia, industry, and regulatory agencies to discuss the latest understanding of NPSs and review the development of therapeutics and biomarkers of NPSs in AD. This review will explore the neurobiology of NPSs in AD and specific symptoms common in AD such as psychosis, agitation, apathy, depression, and sleep disturbances. In addition, clinical trial designs for NPSs in AD and regulatory considerations will be discussed.
