Abstract
Alzheimer's disease considerably compromises communication skills. Language changes become more prominent as the disease progresses. Deterioration of language and cognition reduces the ability of holding conversations, which has a negative impact on social interaction.

Abstract
BACKGROUND Cognitive interventions (either restorative or compensatory) developed for mild Alzheimer's Disease (AD) have been tested widely with cognitive measures, but less is known about how the effects of such interventions are generalizable to daily functioning. In the present study, we looked at affective state and perceived functionality and quality of life indicators, for three different cognitive rehabilitation programs. METHODS Fifty-one AD patients in the mild stage of the disease were selected for the study and were randomly assigned to one of three cognitive training groups: (1) Memo+ (a paper and pencil memory training program); (2) SenseCam (wearable camera used as a passive external memory aid); (3) Written diary (a personal journal, used as control condition). All patients attended 11 sessions, twice a week, of 1-hour length. The three outcome indicators were examined with standardized instruments applied before the intervention, one week after and at six months follow-up. RESULTS After treatment, the SenseCam and Memo+ groups had significantly reduced depressive symptoms compared to the Diary control condition. The same was found for measures of perceived functional capacity. No intervention effects were found for quality of life measures. The immediate effects of the interventions were not maintained at follow-up. CONCLUSIONS Our results suggest that two types of memory rehabilitation can improve depressive symptomology and instrumental activities of daily living, suggesting that these interventions can stimulate not only cognition but also well-being, at least in the short term.

Abstract
INTRODUCTION There is a debate about the ability of patients with Alzheimer's disease to build an up-to-date representation of their memory function, which has been termed mnemonic anosognosia. This form of anosognosia is typified by accurate online evaluations of performance, but dysfunctional or outmoded representations of function more generally. METHOD We tested whether people with Alzheimer's disease could adapt or change their representations of memory performance across three different six-week memory training programs using global judgements of learning. RESULTS We showed that whereas online assessments of performance were accurate, patients continued to make inaccurate overestimations of their memory performance. This was despite the fact that the magnitude of predictions shifted according to the memory training. That is, on some level patients showed an ability to change and retain a representation of performance over time, but it was a dysfunctional one. For the first time in the literature we were able to use an analysis using correlations to support this claim, based on a large heterogeneous sample of 51 patients with Alzheimer's disease. CONCLUSION The results point not to a failure to retain online metamemory information, but rather that this information is never used or incorporated into longer term representations, supporting but refining the mnemonic anosognosia hypothesis.

Abstract
Physical activity can have a positive impact on cognition and well-being in older people. This article reviews and evaluates the effects of planned physical activity programmes on mood, sleep and functional ability in people with dementia. A total of 27 studies between 1974 and 2005 were found. Of these, four included participants living at home, two involved participants who were living either at home or in care homes and 21 included participants living solely in care homes. Since psychosocial intervention can reduce family caregiver burden, the break down of home-care and associated rates of institutionalization, the indirect effects of these physical activity programmes on the family caregiver are also explored. The scope for developing physical activity programmes for people with dementia in primary care using families and volunteers is discussed.

Abstract
BACKGROUND Alzheimer's disease, a global public health issue, accounts for 60 to 80% of all dementias. Alzheimer's disease primarily causes cognitive impairment and drugs have only modest short-term effects, highlighting a pressing need to develop effective interventions. Aerobic exercise holds promise for treating cognitive impairment in Alzheimer's disease through biologically sound mechanisms. Nonetheless, aerobic exercise studies in Alzheimer's disease are limited with mixed findings. METHODS/DESIGN This pilot randomized controlled trial will investigate the effects of a 6-month, individualized, moderate-intensity cycling intervention (20 to 50 minutes per session, 3 times a week) on cognition and hippocampal volume in community-dwelling older adults with mild-to-moderate Alzheimer's disease. The specific aims are to: 1) determine the immediate effect of the cycling intervention on cognition in Alzheimer's disease; 2) examine if the cycling intervention slows cognitive decline in Alzheimer's disease from baseline to 12 months; and 3) assess the effect of aerobic exercise on hippocampal volume over 12 months. Ninety subjects will be randomized on a 2:1 allocation ratio to cycling or attention control (low-intensity stretching) and followed for another 6 months. Allocations will be concealed to all investigators and outcome assessors will be blinded to group assignments and previous data. Cognition will be measured by the Alzheimer's disease Assessment Scale-Cognition at baseline before randomization and at 3, 6, 9, and 12 months. Hippocampal volume will be measured by magnetic resonance imaging at baseline and 6 and 12 months. The sample size of 90 will give 80% power to detect a 2.5-point difference in within-group changes in the Alzheimer's disease Assessment Scale-Cognition at 6 months for the cycling group. DISCUSSION Findings from this study will address the critical gap of exercise efficacy in Alzheimer's disease and use of magnetic resonance imaging as an outcome measure in clinical trials. This study will provide a potential treatment that may increase physical function and quality of life and curb the prohibitive costs for the growing dementia population. TRIAL REGISTRATION Primary registration: (NCT01954550; date of registration: 20 September 2013). Secondary registration: (NCT01954550; date of registration: 1 October 2013).

Abstract
There is a pressing need to establish recruitment, retention, and adherence feasibility to inform clinical trials that will evaluate how exercise affects the symptoms and disease trajectory in Alzheimer's disease (AD). This paper reported the recruitment rate, retention, and adherence from a 6-month cycling study in community-dwelling older adults with mild-to-moderate AD using a single-group, repeated-measures design. Seven recruitment strategies were tested. Participants were prescribed an individualized, 15-45-min moderate intensity cycling 3 times a week for 6 months. The results showed a 1.87 recruitment rate (No. of participants recruited per month per site), 78.6% retention (No. of completers/No. of enrolled participants), and 86.4% adherence (number sessions meeting prescription dose/total number of sessions). The findings addressed a major gap in aerobic exercise studies in AD. Successful recruitment relies on community partnership, whereas strategies for ensuring participant exercise safety collectively improved retention and adherence.

Abstract
BACKGROUND The subjective experience of participating in aerobic exercise is unknown in Alzheimer's disease (AD). OBJECTIVE The purpose of this study was to understand the subjective perceptions of the feasibility and impact of a 6-month, moderate-intensity aerobic exercise intervention by older adults with AD and their family caregivers. METHODS Ten older adults with AD who completed the intervention and their family caregivers participated in four focus group interviews. RESULTS Four converging themes were identified: "There was no perceived positive change in cognitive symptoms," "The 6-month exercise program was socially rewarding," "The 6-month exercise program increased physical strength," and "Participation in aerobic exercise was a positive experience." Family caregivers further identified two additional themes: "The exercise program led to improved attitude in older adults with AD" and "The exercise program reduced caregiver stress." DISCUSSION Aerobic exercise is a feasible and well-perceived intervention for older adults with AD and their family caregivers.

Abstract
Aerobic exercise is a promising behavioral therapy for Alzheimer's disease (AD), yet few studies have investigated the effect of aerobic exercise on cognition in AD. The purpose of this pilot study was to examine the effect of 6-month aerobic exercise on the change in executive function, global cognition, quality of life (QOL), and depression in community-dwelling older adults with mild to moderate AD. A single group, repeated measures design with outcomes measured at baseline, 3 months, and 6 months was used. Results show that there were no significant changes in any measures except for depression (p = .026). There was a trend toward improvement in executive function and QOL with moderate effect sizes (ESs) and a trend toward deterioration in global cognition with moderate to large ESs. Randomized controlled trials are needed to evaluate the therapeutic effect of aerobic exercise in older adults with AD.

Abstract
Some types of formulaic (routine and familiar) language seem to remain fairly intact in people with language and memory disturbances, making it a useful tool for both testing language skills and supporting language retention and use. Proverbs can reasonably be considered a subset of formulaic language, and while it is known that the ability to understand proverbs is compromised in dementia, completing them ought to be relatively easy, if proverbs are stored holistically like other kinds of formulaic language. However, this study reports how three people with dementia often struggled to complete proverbs in a game used in a day-care centre to stimulate the memory and language skills. By examining their responses and relating them to the causes of formulaic language patterns, it is argued that these games are not as appropriate a tool for stimulating memory and language skills as might be first thought. Although they do provide a much-needed opportunity for sustained patient-carer interaction that transcends the basic delivery of physical care needs, the games contravene some of the guidelines offered by Orange (2001) regarding the best way to support people with Alzheimer’s Disease in constructive interaction.

Abstract
Alzheimer's disease is a global, epidemic problem affecting mainly older adults with tremendous social and financial burdens. Older adults with Alzheimer's disease showed reduced physical activity and cognitive changes that are probably amenable to aerobic exercise training. The purpose of this paper is to develop a conceptual model to guide future aerobic exercise research and practice by synthesizing the current state of the science on aerobic exercise training in older adults with AD. The literature review found 12 qualified studies that met the eligibility criteria for inclusion in this review and revealed six constructs (aerobic exercise training, physical fitness, physical performance, activities of daily living limitations, cognition, and psychological and behavioral symptoms), which composed the Functional Impact of aerobic exercise Training in Alzheimer's disease (FIT-AD) model. The state of science on each construct in older adults with Alzheimer's disease is reviewed and summarized. The emerging evidence suggests that aerobic exercise training might positively impacts all five other constructs. The implications of the FIT-AD model for future research and practice are discussed highlighted.

Abstract
With the rapidly aging population, it is expected that increases in cases of dementia will double over the next 20 years. Currently, there is no cure for diseases such as Alzheimer's disease or frontotemporal dementia (FTD) that cause progressive dementia, and only a few pharmacological interventions that slow the progression of the decline exist. Given that there is no cure available, a rehabilitation approach that emphasizes maintaining existing abilities and removing excess disability (as opposed to emphasizing cure or recovery) for as long as possible is warranted. The current paper proposes that nonpharmacological rehabilitation efforts need to target 5 broad areas/targets: memory enhancement, altering social contingencies and communication styles, improving self-care skills, the arrangement of physical environments to maintain and improve functioning, and increasing physical fitness/physical activity. The purpose of this paper is to review specific behaviorally oriented interventions that target these 5 areas and show promise for inclusion in comprehensive rehabilitation efforts for individuals with dementia.

Abstract
While errorless learning and spaced retrieval have both proved effective in helping many patients with acquired brain injury (ABI) and dementia learn novel information, it is not clear which of these principles we should apply to target treatment most effectively. To address this issue we conducted a systematic comparison of these principles in three experiments, comparing their effectiveness in healthy controls (N = 60), patients with ABI (N = 30), and patients with dementia (N = 15). Participants were asked to learn face-name associations, and the relative effectiveness of the principles over and above trial-and-error learning was investigated. The results were remarkably consistent across experiments: Both errorless learning and spaced retrieval produced greater accuracy in name recall than did trial-and-error learning, but recall under conditions of spaced retrieval was significantly better than that under errorless learning. We discuss the implications of these findings and suggest that spaced retrieval may be the stronger memory rehabilitation principle when it comes to learning face-name associations in people with mild to moderate memory impairment.

Abstract
Rehabilitation is a relatively novel concept in dementia. This article explores the potential for rehabilitative approaches in dementia care. On the basis of a structured literature review that focused on the current state of research evidence for rehabilitation related to Alzheimer’s Disease (AD) implications will be discussed for future research in this area and the translational challenges in terms of making findings applicable to care organization and delivery. The article further sets out to critically appraise the concept of ‘evidence’ in the context of rehabilitation methodology. Translational challenges in the application of research evidence in clinical and social care practice are discussed.

Abstract
Alzheimer's disease is the leading cause of dementia in older adults. Although memory problems are the most characteristic symptom of this disorder, many individuals also experience progressive problems with communication. This systematic review investigates the effectiveness of methods to improve the verbal communication of individuals with Alzheimer's disease with their caregivers. The following databases were reviewed: PsychINFO, CINAHL, EMBASE, MEDLINE, REHABDATA, and COMDIS. The inclusion criteria were: (i) experimentally based studies, (ii) quantitative results, (iii) intervention aimed at improving verbal communication of the affected individual with a caregiver, and (iv) at least 50% of the sample having a confirmed diagnosis of Alzheimer's disease. A total of 13 studies met all of the inclusion criteria. One technique emerged as potentially effective: the use of memory aids combined with specific caregiver training programs. The strength of this evidence was restricted by methodological limitations of the studies. Both adoption of and further research on these interventions are recommended.

Abstract
The effects of long-term treatment in a demented patient were evaluated in this study. One individual diagnosed with Alzheimer's dementia (AD) was treated with neuropsychological rehabilitation techniques as well as drugs for a period of 2 years and 10 months. An A-B-A-B design was performed for the cognitive treatment. Neuropsychological treatment consisted of a combination of direct re-training and training in activities of daily living. Cognitive performance was monitored with the Mattis Dementia Rating Scale. Results showed improvement and a slower decline during the treatment phases (A) as compared to the no-treatment phases (B). The Conceptualisation and Attention subscales benefited most followed by the Memory subscale. Long-term treatment was shown to be effective in AD. Although cognitive drugs may have been beneficial neuropsychological rehabilitation played an important role in the success of this treatment, appearing as a necessary condition.

Abstract
This randomized study evaluated the combined effect of a cognitive-communication program plus an acetylcholinesterase inhibitor (donepezil; donepezil-plus-stimulation group; n = 26), as compared with donepezil alone (donepezil-only group; n = 28) in 54 patients with mild to moderate Alzheimer's disease (AD; Mini-Mental Status Examination score of 12- 28) ranging in age from 54 to 91 years. It was hypothesized that cognitive-communication stimulation in combination with donepezil would positively affect the following: (a) relevance of discourse, (b) performance of functional abilities, (c) emotional symptoms, (d) quality of life, and (e) overall global function, as measured by caregiver and participant report and standardized measures. Cognitive-communication, neuropsychiatric, functional performance, and quality of life evaluations were conducted at baseline and Month 4, the month after the 2-month active stimulation period. Follow-up evaluations were performed at Months 8 and 12. The stimulation program consisted of 12 hr of intervention over an 8-week period and involved participant-led discussions requiring homework, interactive sessions about AD, and discussions using salient life stories. Additive effects of active stimulation with donepezil were examined in 2 ways: (1) comparing mean group performance over time and (2) evaluating change scores from baseline. A Group x Time interaction was found for the donepezil-plus-stimulation group in the emotional symptoms of apathy and irritability as compared with the donepezil-only group. Evaluation of change scores from baseline to 12 months revealed a positive effect for the donepezil-plus-stimulation group on discourse and functional abilities with a trend on apathy, irritability, and patient-reported quality of life. In sum, the research revealed benefits to the donepezil-plus-stimulation group in the areas of discourse abilities, functional abilities, emotional symptoms, and overall global performance. This study adds to growing evidence that active cognitive stimulation may slow the rate of verbal and functional decline and decrease negative emotional symptoms in AD when combined with acetylcholinesterase inhibitors, indicating a need to advance research in the area of cognitive treatments. The fact that AD is a progressive brain disease should not preclude ameliorative treatment.

Abstract
UNLABELLED This article describes a comprehensive cognitive-linguistic intervention program for mild to moderate Alzheimer's disease (AD) patients that provided communication skills practice in the context of health-enhancing and esteem-building community-based activities: physical fitness training and supervised volunteer work. The interventions were administered by undergraduate students who completed academic work, received faculty supervision, and earned three credits for one semester of participation. Effects of the interventions on the discourse of four participants who completed all 4 years of the program are reported in detail. The maintained or improved performance on multiple discourse outcome measures provides powerful rationale for making such interventions more widely available and preliminary support for their effectiveness in preserving communicative function. An additional role for speech-language pathologists (SLPs)--as trainers and supervisors of non-professional rehab partners for persons with dementia--is proposed. LEARNING OUTCOMES From this article, participants will be able to (1) list specific language tasks that can be used to assess discourse in individuals with AD; (2) identify several cognitive-linguistic interventions appropriate for use with AD patients; and (3) understand how long-term cognitive-linguistic interventions may affect the language performance of individuals with AD.

Abstract
At a time when they are losing skills in virtually all arenas of life, persons with Alzheimer's disease can experience significant, esteem-building achievements in physical fitness and mood through supervised participation in an exercise program. The effects of physical exercise plus cognitive and social stimulation on persons with early stage Alzheimer's disease were assessed in a longitudinal study. Twenty-four such individuals, aged 54 to 88 at program entry, participated in 16 to 20 exercise sessions and 10 community activity sessions per semester for two to eight semesters. Half of the weekly exercise sessions included memory and language stimulation activities. Students, supplemented by family caregivers, supervised the sessions. Exercise sessions consisted of flexibility, balance, aerobic, and weight resistance activities. Preparticipation and semiannual post-testing of aerobic fitness and duration and upper and lower body strength was done. Highly significant fitness gains (p < .001) were achieved in the six-minute walk test, upper and lower body strength, and duration of aerobic exercise. Five participants, aged 86 to 91, completed six to eight semesters and were doing 27 to 45 minutes of aerobics per session at program's end. Five participants scored within the normal range for age-matched healthy active adults on the six-minute walk test at baseline. Nine others achieved and three exceeded the normal range during treatment. Cognitive decline was slowed and mood improved. First-year cognitive outcomes have been published elsewhere. An article reporting final cognitive outcomes is in preparation; Outcome data is summarized on the project website: www.u.arizona.edu/ ~sarkin/elderrehab.html. The benefits of physical exercise can be made available at nominal cost to Alzheimer's patients and other elderly persons by using students to provide transportation, supervision, and the motivational support that is key to exercise adherence. Further research is needed to determine the relative contributions of each program component to the positive outcomes.

Abstract
UNLABELLED Three direct measures of dementia insight were administered to 20 participants in a longitudinal Alzheimer's disease (AD) rehabilitation research project and to subsets of these participants that completed one (N = 19), two (N = 12), and three (N = 6) years of program participation. The measures were: (1) responses to a discourse prompt question about AD (ADPQ); (2) endorsements of seven items on the Geriatric Depression Scale (GDS) about the effects of dementia (separate analyses were done for two of the seven items that related specifically to memory and thinking); and (3) a sentence-completion exercise. Responses to measures 1 and 2 and the subset of 2 were quantified, tracked over time, and subjected to correlational analyses with age, Mini-Mental State Exam (MMSE) score, and depression, as measured by total GDS score, and with each other. MAJOR FINDINGS There were no decreases in insight from baseline to year 1, 2, or 3, as measured by free responses to the AD prompt question. There was a significant decline in insight from baseline to year one on the GDS measure, but no change from year 1 to year 2 and a return to baseline level at year 3. There was no correlation between insight and baseline age, between insight and MMSE score at any time point, between MMSE score and depression, as measured by total GDS score, or between MMSE score and depression score, except for the year 3 completers, where depression score was negatively correlated with MMSE score at year 3 only. GDS insight and ADPQ scores were not correlated. Several participants that showed no insight on the quantified measures did so on the sentence completions.
