Detection of long-term care (LTC) residents at risk of delirium may lead to prevention of this disorder. The primary objective of this study was to determine if the presence of one or more Confusion Assessment Method (CAM) core symptoms of delirium at baseline assessment predicts incident delirium. Secondary objectives were to determine if the number or the type of symptoms predict incident delirium. ⋯ The presence of CAM core symptoms at baseline assessment predicts incident delirium in older LTC residents. These findings have potentially important implications for clinical practice and research in LTC settings.

Randomized Controlled Trial
A randomized, double-blind, placebo-controlled trial of memantine in a behaviorally enriched sample of patients with moderate-to-severe Alzheimer's disease.
Agitation and aggression in Alzheimer's disease (AD) are amongst the most serious of neuropsychiatric symptoms, and contribute to poor outcomes and worse quality of life. Previous studies have suggested a benefit for memantine on agitation and aggression, but none have examined its efficacy in community-dwelling patients with significant agitation and aggression at baseline, utilizing these behaviors as a primary outcome measure. ⋯ The study failed to show the superiority of memantine in this sample of patients with moderate-to-severe AD with significant baseline agitation and aggression. Methodological limitations could have contributed to these results.

Exercising choice and control over decisions is central to quality of life. The Mental Capacity Act 2005 (England and Wales) provides a legal framework to safeguard the rights of people with dementia to make their own decisions for as long as possible. The impact of this on long-term planning has been investigated; everyday decision-making in people's own homes remains unexplored. ⋯ Carers may gradually take on decision-making for people with dementia. This can bring with it added stresses, such as determining their relative's decision-making capacity and weighing up what is in their best interests. Practitioners and support services should provide timely advice to carers and people with dementia around everyday decision-making, and be mindful how abilities may change.

Caring for a relative with dementia has been associated with high levels of psychological morbidity in carers. Sense of coherence is an important resource of successful coping with caregiving. The purpose of the present study was to examine the relationship between stress associated with caregiving, sense of coherence, and self-reported depression and anxiety in family carers of people with dementia. We hypothesized that carers reporting high levels of anxiety and depression will report low levels of coherence, and that the relationship between caregiver stress and affective symptoms will be mediated by sense of coherence. ⋯ Carers reporting high levels of anxiety and depression are more likely to report low levels of sense of coherence. The relationship between stress related to caregiving and depressive symptoms is mediated by carers' self-reported sense of coherence. Future psychotherapeutic intervention studies in family carers of people with dementia may incorporate strategies that specifically target sense of coherence.

Although knowledge of established risk factors for Alzheimer's disease (AD) can logically contribute to the search for predictors of the progression of cognitive impairment, it has not yet been firmly established where in the cognitive impairment process these risk factors exert their effects and how to predict quantitatively for the progression of mild cognitive impairments (MCI) to AD. This study aimed to determine whether known risk factors increased the risk of progression from MCI to AD and to make prediction based on transition probabilities. ⋯ Known risk factors influenced differently for different transitions. Transition from global impairment was more likely to worsen to severe cognitive deterioration than transition from MCI.
