Public Health.

Background: Some individual-level interventions for dementia risk factors could be cost saving. We aimed to estimate the cost effectiveness of population-level interventions for tackling dementia risk factors. We found such interventions for tobacco smoking, excess alcohol use, diet modification to decrease hypertension and obesity, air pollution, and head injury.

Public Health.

Background: Approximately 40% of global dementia cases are associated with 12 modifiable risk factors (less education, hearing loss, hypertension, obesity, smoking, depression, social isolation, physical inactivity, diabetes, alcohol excess, air pollution, and traumatic brain injury). However, the number of people with these risk factors differs between populations. Latin American countries differ in socioeconomic and geographic aspects and, therefore, risk factors prevalence.

Developing Topics.

Background: Sleep disturbance is common and distressing for people with dementia, with no known safe, effective treatments. We previously developed and delivered DREAMS-START (Dementia RElAted Manual for Sleep; STrAtegies for RelaTives), a multimodal non-pharmacological intervention, and demonstrated feasibility and acceptability. This randomised controlled trial (RCT) aimed to establish whether DREAMS-START is clinically-effective in reducing sleep disturbances in people with dementia at home after 8 months compared to usual care.

Dementia Care Research and Psychosocial Factors.

Background: The progressive nature of dementia and the complex needs means that people living with dementia require tailored approaches to address their changing care needs over time. These include physical multimorbidity, psychological, behavioural, and cognitive symptoms and possible risks arising from these and helping family caregivers. However, provision of these interventions is highly variable between and within countries, partly due to uncertainty about their efficacy and scarce resources.

Dementia Care Research and Psychosocial Factors.

Background: Data from high-income countries (HICs) suggest a decline in age-specific incidence rates of dementia. However, this has happened primarily in HICs, with low- and middle- income countries (LMICs) facing two main challenges: a higher burden of risk factors and, in general, a faster ageing population. Most people with dementia live in LMICs, and this is set to increase, thus requiring urgent and robust action to prevent, treat and support people with dementia and their families.
