Prof J Cohen-Mansfield), and Minerva Center for Interdisciplinary Study of End of Life (Prof J Cohen-Mansfield),should consider dementia in older people without known dementia who have frequent admissions or who develop delirium. Delirium is common in people with dementia and contributes to cognitive decline. In hospital, care including appropriate sensory stimulation, ensuring fluid intake, and avoiding infections might reduce delirium incidence.Acting now on dementia prevention, intervention, and care will vastly improve living and dying for individuals with dementia and their families, and thus society.

People with dementia are usually older, often have co-morbidities and may need help in coping with these illnesses. A third of older people now die with dementia and all professionals working in endof-life care need to make this a central part of their planning and communication. In this commission, we have detailed evidence-based approaches to dementia and its symptoms. Services should be available, scalable and give value. As there are limited resources, professionals and services need to use what works, not use what is ineffective, and be aware of the difference. Overall, there is good potential for prevention and, once someone develops dementia, for care to be high-quality, accessible, and give value to an under-served, growing population. Effective dementia prevention and care could transform the future for society and vastly improve living and dying for individuals with dementia and their families. Acting now on what we already know can make this difference happen. Key Messages 1 There are increasing numbers of people with dementia globally although incidence in some countries has decreased. 2 Be ambitious about prevention: We recommend energetically treating hypertension in middle aged and older people without dementia to reduce dementia incidence. Interventions for other risk factors, including more childhood education, exercise, maintaining social engagement, reducing smoking, and management of hearing loss, depression, diabetes and obesity; may have the potential of delaying or preventing a third of dementias. 3 Treat cognitive symptoms: To maximise cognition, people with Alzheimer's dementia or Dementia with Lewy Bodies should be offered Cholinesterase Inhibitors (ChEIs)at all stages, or memantine for severe dementia. ChEIs are not effective in Mild Cognitive Impairment. 4 Individualise dementia care: Good dementia care spans medical, social and supportive care, should be tailored to unique individual and cultural needs, preferences, priorities, and should incorporate support for the family carers 5 Care for family carers. Family carers are at high risk of depression. Effective interventions reduce the risk and treat the symptoms, include START (Strategies for Relatives) or REACH (Resources for Enhancing Alzheimer's Caregiver Health intervention) and should be made available. 6 Plan for the future. People with dementia and their families value discussions about the future and decisions about possible attorneys to make decisions. Clinicians should consider capacity to make different types of decisions at diagnosis. 7 Protect people with dementia. People with dementia and society require protection from possible risks of the condition, including self-neglect, vulnerability including to exploitation, managing money, driving or using weapons. Risk assessment and management at all stages of the disease is essential but it should be balanced against the persons' right to autonomy. 8 Manage neuropsychiatric symptoms. Management of the neuropsychiatric symptoms of dementia including agitation, low mood or psyc...

The QOL-AD seems to be reliable and valid for individuals with MMSE scores greater than 10. Further research is needed to clarify the relationship between patient and caregiver reports of patient quality of life and to identify factors that influence quality of life throughout the progression of dementia.

Checklist (RMBPC), a 24-item, caregiver-report measure of observable behavioral problems in dementia patients, provides 1 total score and 3 subscale scores for patient problems (memory-related, depression, and disruptive behaviors) and parallel scores for caregiver reaction. Data were obtained from 201 geriatric patients and their caregivers. Factor analysis confirmed 3 first-order factors, consistent with subscales just named, and 1 general factor of behavioral disturbance. Overall scale reliability was good, with alphas of .84 for patient behavior and .90 for caregiver reaction. Subscale alphas ranged from .67 to .89. Validity was confirmed through comparison of RMBPC scores with well-established indexes of depression, cognitive impairment, and caregiver burden. The RMBPC is recommended as a reliable and valid tool for the clinical and empirical assessment of behavior problems in dementia patients.

Introduction: Nonpharmacological therapies (NPTs) can improve the quality of life (QoL) of people with Alzheimer’s disease (AD) and their carers. The objective of this study was to evaluate the best evidence on the effects of NPTs in AD and related disorders (ADRD) by performing a systematic review and meta-analysis of the entire field. Methods: Existing reviews and major electronic databases were searched for randomized controlled trials (RCTs). The deadline for study inclusion was September 15, 2008. Intervention categories and outcome domains were predefined by consensus. Two researchers working together detected 1,313 candidate studies of which 179 RCTs belonging to 26 intervention categories were selected. Cognitive deterioration had to be documented in all participants, and degenerative etiology (indicating dementia) had to be present or presumed in at least 80% of the subjects. Evidence tables, meta-analysis and summaries of results were elaborated by the first author and reviewed by author subgroups. Methods for rating level of evidence and grading practice recommendations were adapted from the Oxford Center for Evidence-Based Medicine. Results: Grade A treatment recommendation was achieved for institutionalization delay (multicomponent interventions for the caregiver, CG). Grade B recommendation was reached for the person with dementia (PWD) for: improvement in cognition (cognitive training, cognitive stimulation, multicomponent interventions for the PWD); activities of daily living (ADL) (ADL training, multicomponent interventions for the PWD); behavior (cognitive stimulation, multicomponent interventions for the PWD, behavioral interventions, professional CG training); mood (multicomponent interventions for the PWD); QoL (multicomponent interventions for PWD and CG) and restraint prevention (professional CG training); for the CG, grade B was also reached for: CG mood (CG education, CG support, multicomponent interventions for the CG); CG psychological well-being (cognitive stimulation, multicomponent interventions for the CG); CG QoL (multicomponent interventions for PWD and CG). Conclusion: NPTs emerge as a useful, versatile and potentially cost-effective approach to improve outcomes and QoL in ADRD for both the PWD and CG.

These results suggest that regular exercise is associated with a delay in onset of dementia and Alzheimer disease, further supporting its value for elderly persons.

T IS WELL-KNOWN THAT ALZHEIMER disease adversely affects cognitive, emotional, and behavioral functioning. 1 Less well-known are the deleterious effects of Alzheimer disease on physical conditioning. However, there are a number of studies linking Alzheimer disease with physical deterioration. For example, when compared with age-matched controls, Alzheimer disease patients show more signs of undernutrition, 2 higher risk of falls and fractures, 3-6 and more rapid decline on measures of mobility. 7,8 Once injured, Alzheimer disease patients are at greater risk of subsequent injury than age-and sex-matched controls. 3 Reduced muscle mass has also been associated with loss of independence. 9 Consequently, improved physical conditioning for patients with Alzheimer disease may extend their independent mobility and enhance their quality of life despite progression of the disease. Research is accumulating to suggest that even the oldest adults can improve cardiovascular function and in-Author Affiliations are listed at the end of this article.

Our dementia and AD incidence rates are consistent with recent US and European cohort studies, providing clinicians and researchers new information concerning the reproducibility of incidence estimates across settings. Increased risk was associated with age and the apolipoprotein E genotype; also with a low baseline cognitive screening test score. Educational level was inversely associated with the risk of dementia and positively associated with the baseline cognitive test score; thus, detection of AD by the screening test could also be influenced by educational level.
