Background: During the COVID-19 pandemic we implemented a partially online music intervention to examine the feasibility, experiences and short-term outcomes on the challenging behaviour and well-being of adults with intellectual disabilities.

Method: This mixed-methods study included 10 participants with mild or moderate intellectual disabilities who received 16 one-hour individual music sessions in 10 weeks, either face-to-face or online. Data on feasibility and experiences from participants and music workers were collected and analysed using inductive thematic analysis.

Background: Dementia is often associated with Neuropsychiatric Symptoms (NPS) such as agitation, depression, hallucinations, anxiety, that can cause distress for the resident with dementia in long-term care settings and can impose emotional burden on the environment. NPS are often treated with psychotropic drugs, which, however, frequently cause side effects. Alternatively, non-pharmacological interventions can improve well-being and maintain an optimal quality of life (QoL) of those living with dementia.

Aim: A prospective design was used to investigate the relationship of current psychiatric symptoms of incarcerated people with serious mental illness (SMI) and aggressive behavior on a penitentiary ward for crisis intervention.

Methods: One hundred sixty detainees with SMI, detained in a high-security penitentiary psychiatric facility, were screened every 2 weeks with the Brief Psychiatric Rating Scale-Extended (BPRS-E) by trained clinicians, to ensure that the data on psychiatric symptoms were up-to-date. Aggressive behavior was registered with the Staff Observation Aggression Scale-Revised.

Background: Increasing physical activity is one of the most promising and challenging interventions to delay or prevent cognitive decline and dementia.

Methods: We conducted a randomized controlled trial to assess the effects of a physical activity intervention, aimed at increasing step count, in elderly with low levels of physical activity on measures of strength, balance, aerobic capacity, and cognition. Participants were assigned to 9 months of exercise counseling or active control.

Background: Research on the association between physical inactivity and cognitive decline and dementia is dominated by studies with short-term follow-up, that might be biased by reverse causality.

Objective: Investigate the long-term association between physical activity, cognition, and the rate of age-associated cognitive decline.

Methods: We investigated the association between late-life physical activity and executive functioning and rate of decline of executive abilities during follow-up of up to 16 years, in 3553 participants of the prospective Rotterdam Study cohort.

Physical exercise affects hippocampal structure and function, but the underlying neural mechanisms and the effects of exercise intensity remain incompletely understood. Therefore, we undertook a comprehensive, multi-modal 3T and 7T MRI randomized controlled trial (Netherlands Trial Register - NL5847) in which we randomized 52 young, non-athletic volunteers to a 12-week low- or high-intensity exercise program. Using state-of-the-art methods, we investigated changes in hippocampal volume, as well as changes in vasculature, neuro-metabolites, and peripheral growth factors as potential underpinnings.

Pain is one of the most common health problems and has a severe impact on quality of life. Yet, a suitable and efficient treatment is still not available for all patient populations suffering from pain. Interestingly, recent research shows that low threshold mechanosensory C-tactile (CT) fibres have a modulatory influence on pain.

Background: Understanding if and how pain influences activities of daily living (ADL) in dementia is essential to improving pain management and ADL functioning. This study examined the relationship between the course of pain and change in ADL functioning, both generally and regarding specific ADL functions.

Methods: Participants were Dutch nursing home residents (n = 229) with advanced dementia.

Cognitive reserve (CR) is known to reduce or even protect against the negative effects of aging on cognitive functioning. Nonetheless, little is known about how CR influences the relationship between different cognitive abilities and age in the old-old. The goal of the present study was, therefore, to test the hypothesis whether, in the old-old, CR still modifies the relationship between age and cognitive functioning.

: Previous studies suggest an association between poor mastication and cognitive impairment. The role of chewing efficiency and dentition in this relation is unclear. The aim was to examine global cognitive functioning and dentition as predictors for chewing efficiency, in older people with mild cognitive impairment (MCI) or dementia.

: Over the past decade, a trend has been noticed in the Netherlands to replace large-scaled special care units (SCUs) caring for 20-30 residents with dementia by small-scaled SCUs caring for up to 8 residents. Systematic evaluations, however, have yielded a differentiated picture of the effects. As the impact on psychotropic drug use has hardly been addressed thus far, we examined the (potential) impact of psychotropic drug use when moving residents with dementia from large-scaled to small-scaled SCUs.

: Alterations in insulin-like growth factor I (IGF-I) signaling have been associated with dementia and Alzheimer's disease (AD). Studies on the association between IGF-I levels and dementia risk have been inconclusive. We reported earlier that higher levels of IGF-I receptor stimulating activity are associated with a higher prevalence and incidence of dementia.

Background: Nursing home residents with dementia show a rapid decline in their ability to perform activities of daily living. This decline is linked to a greater care dependency, which is associated with a reduced quality of life. Care dependency is influenced by multiple predictors, yet current research often focuses on the contribution of a single or a small number of predictors of care dependency.

Background: Previous literature has shown a putative relationship between playing a musical instrument and a benefit in various cognitive domains. However, to date it still remains unknown whether the exposure to a musically-enriched environment instead of playing an instrument yourself might also increase cognitive domains such as language, mathematics or executive sub-functions such as for example planning or working memory in primary school children.

Design: Cross-sectional.
