RESUMO
AIMS: The establishment of a vascular surgeon-led emergency diabetic foot service in 2006 has evolved to provide lower limb wound care for patients with and without diabetes. We aimed to determine whether the service was associated with sustained, improved limb salvage rates for the whole population, analyse key aspects of service provision and compare outcomes against published studies. METHODS: The vascular unit serves a largely rural population of approximately 240,000. Data was collected prospectively on lower limb amputations, arterial and minor surgical interventions from 2006 to 2015, and retrospectively retrieved for 2004-2005, prior to service commencement. Data was also collected on referral patterns, volume of patient admissions and attendances, and delays. Lower limb amputation rates were compared against published data and analysis of admission trends and delays employed non-parametric tests. RESULTS: Age/gender adjusted major lower limb amputations for the populations with and without diabetes were 412/100,000 in 2004 and 15/100,000 in 2005 respectively. Following service introduction, major amputations reduced and since 2012 have been sustained at between 15-44/100,000 and 1-3/100,000 for patients with and without diabetes respectively, comparing favourably with published data. Vascular interventions have remained static, but referrals of patients directly to the service and numbers of minor procedures have increased. CONCLUSIONS: The sustained decreases in all major lower limb amputations that have coincided with the development of a core team approach to providing rapid access and comprehensive care for patients with emergency diabetic foot problems may indicate that this service design benefits patients with and without diabetes.

BACKGROUND: Venous thromboembolism (VTE) prophylaxis in an important aspect of the care of hospitalised patients, for which the National Institute for Health and Care Excellence (NICE) has issued guidance. Guidance compliance continues to be a concern. Junior doctors are the main group responsible for prescribing thromboprophylaxis. We aimed to compare local pharmacological thromboprophylaxis prescribing against NICE guidelines in a surgical department at a district general hospital, and determine whether interventions aimed at improving compliance were effective. METHODS: Over four months, a two cycle audit of prescribing patterns for VTE prophylaxis was performed using data collected at four intervals: 1. Baseline 2. Following pro-forma introduction and feedback 3. A second baseline data collection. 4. Following VTE prophylaxis teaching. RESULTS: A total of 394 admissions were included. Correct identification and prescribing for at-risk patients ranged between 76 and 93 %, whilst risk assessment documentation and explanation to patients occurred in fewer than 50 and 66 % respectively. Prescribing and risk assessment improved in the first cycle (chi2 = 6.75, p = 0.009 and chi2 = 10.70, p = 0.001 respectively), a consequence of one specialty improving following additional feedback. Teaching was not associated with improvements. Overall compliance with NICE guidelines was achieved in no more than 25 % of admissions. CONCLUSIONS: Despite junior doctors generally prescribing VTE thromboprophylaxis appropriately, overall compliance with guidelines remained poor regardless of educational interventions. Verbal feedback was the only intervention associated with modest improvements. A pressurised work environment may limit the impact of educational interventions. Guidance simplification or devolving responsibility to other members of staff may improve compliance.

The observation of a bilingual advantage in executive control tasks involving inhibition and management of response conflict suggests that being bilingual might contribute to increased cognitive reserve. In support of this, recent evidence indicates that bilinguals develop Alzheimer's disease (AD) later than monolinguals, and may retain an advantage in performance on executive control tasks. We compared age at the time of receiving an AD diagnosis in bilingual Welsh/English speakers (n = 37) and monolingual English speakers (n = 49), and assessed the performance of bilinguals (n = 24) and monolinguals (n = 49) on a range of executive control tasks. There was a non-significant difference in age at the time of diagnosis, with bilinguals being on average 3 years older than monolinguals, but bilinguals were also significantly more cognitively impaired at the time of diagnosis. There were no significant differences between monolinguals and bilinguals in performance on executive function tests, but bilinguals appeared to show relative strengths in the domain of inhibition and response conflict. Bilingual Welsh/English speakers with AD do not show a clear advantage in executive function over monolingual English speakers, but may retain some benefits in inhibition and management of response conflict. There may be a delay in onset of AD in Welsh/English bilinguals, but if so, it is smaller than that found in some other clinical populations. In this Welsh sample, bilinguals with AD came to the attention of services later than monolinguals, and reasons for this pattern could be explored further.

The study investigated different types of awareness of memory dysfunction in dementia, specifically judgements concerning memory task performance or appraisal of everyday memory functioning and also exploring the neuropsychological correlates of such awareness. This was investigated in 76 people with dementia, comprising 46 patients with Alzheimer's disease (AD) and 30 patients with vascular dementia (VaD). The Memory Awareness Rating Scale (Clare et al., 2002, Neuropsychol Rehabil, 12, 341-362) was used, which includes an Objective-Judgement Discrepancy (OJD) technique involving comparison of subjective evaluation of performance on specific memory tasks with actual performance, and a Subjective Rating Discrepancy (SRD) technique, which compares self versus informant judgement of everyday memory function. The AD and VaD groups showed lower awareness than a normal control group for both types of measures, the AD group showing less awareness than the VaD group on the OJD measure. Regression analyses supported associations for both groups between memory impairment and the OJD measure and between naming impairment and the SRD measure. The findings are discussed in terms of neurocognitive theories accounting for loss of awareness in dementia.

Objective. Bilingualism has been shown to benefit executive function (EF) and delay the onset of Alzheimer's disease. This study aims at examining whether a bilingual advantage applies to EF in Parkinson's disease (PD). Method. In a cross-sectional outpatient cohort of monolingual English (n = 57) and bilingual Welsh/English (n = 46) speakers with PD we evaluated the effects of bilingualism compared with monolingualism on performance on EF tasks. In bilinguals we also assessed the effects of the degree of daily usage of each language and the degree of bilingualism. Results. Monolinguals showed an advantage in performance of language tests. There were no differences in performance of EF tests in monolinguals and bilinguals. Those who used Welsh less in daily life had better performance on one test of English vocabulary. The degree of bilingualism correlated with one test of nonverbal reasoning and one of working memory but with no other tests of EF. Discussion. The reasons why the expected benefit in EF in Welsh-English bilinguals with PD was not found require further study. Future studies in PD should include other language pairs, analysis of the effects of the degree of bilingualism, and longitudinal analysis of cognitive decline or dementia together with structural or functional neuroimaging.
RESUMO
BACKGROUND: Lifestyle factors represent prime targets for behaviour change interventions to promote healthy ageing and reduce dementia risk. We evaluated a goal-setting intervention aimed at promoting increased cognitive and physical activity and improving mental and physical fitness, diet and health. METHODS: This was a pilot randomised controlled trial designed to guide planning for a larger-scale investigation, provide preliminary evidence regarding efficacy, and explore feasibility and acceptability. Primary outcomes were engagement in physical and cognitive activity. Participants aged over 50 living independently in the community were recruited through a community Agewell Centre. Following baseline assessment participants were randomly allocated to one of three conditions: control (IC) had an interview in which information about activities and health was discussed; goal-setting (GS n = 24) had an interview in which they set behaviour change goals relating to physical, cognitive and social activity, health and nutrition; and goal-setting with mentoring (GM, n = 24) had the goal-setting interview followed by bi-monthly telephone mentoring. Participants and researchers were blinded to group assignment. Participants were reassessed after 12 months. RESULTS: Seventy-five participants were randomised (IC n = 27, GS n = 24, GM n = 24). At 12-month follow-up, the two goal-setting groups, taken together (GS n = 21, GM n = 22), increased their level of physical (effect size 0.37) and cognitive (effect size 0.15) activity relative to controls (IC n = 27). In secondary outcomes, the two goal-setting groups taken together achieved additional benefits compared to control (effect sizes ≥ 0.2) in memory, executive function, cholesterol level, aerobic capacity, flexibility, balance, grip strength, and agility. Adding follow-up mentoring produced further benefits compared to goal-setting alone (effect sizes ≥ 0.2) in physical activity, body composition, global cognition and memory, but not in other domains. Implementation of the recruitment procedure, assessment and intervention was found to be feasible and the approach taken was acceptable to participants, with no adverse effects. CONCLUSIONS: A brief, low-cost goal-setting intervention is feasible and acceptable, and has the potential to achieve increased activity engagement.

BACKGROUND: Self-report quality of life (QoL) measures for people with dementia are widely used as outcome measures in trials of dementia care interventions. Depressed mood, relationship quality and neuropsychiatric symptoms predict scores on these measures, whereas cognitive impairment and functional abilities typically do not. This study examines whether these self-reports are influenced by personality and by the person's awareness of his/her impairments. A strong negative association between QoL and awareness of deficits would have implications for the validity of self-report in this context and for therapeutic interventions aiming to increase adjustment and coping. METHODS: Participants were 101 individuals with earlyâstage dementia and their family carers participating in the Memory Impairment and Dementia Awareness (MIDAS) Study. QoL was assessed using the QoL-AD scale, and awareness was assessed in relation to memory, activities of daily living and social functioning. Self-concept, conscientiousness, quality of relationship and mood were assessed and a brief neuropsychological battery administered. Carers rated their own stress and well-being and reported on neuropsychiatric symptoms. A series of regression analyses predicting QoL-AD were carried out, identifying key variables in each domain of assessment to take forward to an overall model. RESULTS: Cognitive impairment was not related to QoL. The final model accounted for 57% of the variance in QoL-AD scores, with significant contributions from depressed mood, severity of irritability shown by the person with dementia, self-concept, quality of relationship (rated by the person with dementia) and male gender. The bivariate relationships of QoL-AD with awareness of memory function, awareness of functional abilities and conscientiousness were mediated by both depressed mood and self-concept. CONCLUSIONS: This study reports the most comprehensive approach to evaluation of awareness to date. Most of the indices of awareness used are not related to self-reported QoL. Discrepancies in evaluative judgements of memory function and functional abilities between people with dementia and carers are related to QoL, but this relationship is mediated by both depressed mood and self-concept, which have a much stronger relationship with QoL. The validity of self-report measures of QoL in people with early stage dementia is supported by these results.

Despite much research on the relationship between awareness and dementia little can be concluded concerning their relationship and the role of other factors. It is likely that studies capture different phenomena of awareness. This study aimed at identifying and delineating such variation by analysing data from three questionnaires obtained during the longitudinal study of awareness in 101 people with early-stage dementia. The data concerned awareness in relation to memory, activities of daily living and socio-emotional function. Significant differences in patterns of discrepancies were obtained. This suggests that the awareness phenomena involved were structurally different; and that, in turn, this may reflect variation in the intrinsic linking between awareness and its 'object' (different 'objects' determining different kinds of judgements). The identification of such differences is necessary so that appropriate methodologies can be applied to the study of awareness in different contexts.

Attachment bonds are important for personality development, emotion regulation and mental health throughout the lifespan. This systematic review explores the relevance of attachment for people with dementia, and how attachment influences the experience of caregivers of people with dementia. Eighteen studies were included. Three focused on attachment in terms of parent fixation in dementia, three examined attachment behaviour in dementia, five addressed attachment and dementia-related behavioural problems, and seven concentrated on attachment in caregivers. Attachment behaviours were evident at various stages of dementia and the presence of parent fixation was observed when attachment needs were not being met. Insecure attachment was related to neuropsychiatric symptoms. Attachment security had important consequences for caregiver psychological health. Implications of methodological issues such as the choice of respondent, measurement issues, and the lack of a longitudinal perspective are discussed. The implications of attachment for the support of people with dementia and caregivers are considered.

OBJECTIVE: We compared mindfulness-based cognitive therapy (MBCT) with both cognitive psychological education (CPE) and treatment as usual (TAU) in preventing relapse to major depressive disorder (MDD) in people currently in remission following at least 3 previous episodes. METHOD: A randomized controlled trial in which 274 participants were allocated in the ratio 2:2:1 to MBCT plus TAU, CPE plus TAU, and TAU alone, and data were analyzed for the 255 (93%; MBCT = 99, CPE = 103, TAU = 53) retained to follow-up. MBCT was delivered in accordance with its published manual, modified to address suicidal cognitions; CPE was modeled on MBCT, but without training in meditation. Both treatments were delivered through 8 weekly classes. RESULTS: Allocated treatment had no significant effect on risk of relapse to MDD over 12 months follow-up, hazard ratio for MBCT vs. CPE = 0.88, 95% CI [0.58, 1.35]; for MBCT vs. TAU = 0.69, 95% CI [0.42, 1.12]. However, severity of childhood trauma affected relapse, hazard ratio for increase of 1 standard deviation = 1.26 (95% CI [1.05, 1.50]), and significantly interacted with allocated treatment. Among participants above median severity, the hazard ratio was 0.61, 95% CI [0.34, 1.09], for MBCT vs. CPE, and 0.43, 95% CI [0.22, 0.87], for MBCT vs. TAU. For those below median severity, there were no such differences between treatment groups. CONCLUSION: MBCT provided significant protection against relapse for participants with increased vulnerability due to history of childhood trauma, but showed no significant advantage in comparison to an active control treatment and usual care over the whole group of patients with recurrent depression.

BACKGROUND: Little evidence is available about how quality of life (QoL) changes as dementia progresses. OBJECTIVES: We explored QoL trajectories over a 20-month period and examined what predicted change in QoL. METHOD: Fifty-one individuals with a diagnosis of Alzheimer's, vascular or mixed dementia (people with dementia (PwD)) participating in the Memory Impairment and Dementia Awareness Study rated their QoL using the QoL-Alzheimer's Disease Scale at baseline and at 20-month follow-up. PwD also rated their mood and quality of relationship with the carer. In each case, the carer rated his or her level of stress and perceived quality of relationship with the PwD. RESULTS: There was no change in mean QoL score. Nearly one-third of PwD rated QoL more positively at 20-month follow-up and nearly one-third rated QoL more negatively. These changes could be regarded as reliable in one-quarter of the sample. Participants taking acetylcholinesterase-inhibiting medication at baseline were more likely to show a decline in QoL score. There were no other significant differences between those whose scores increased, decreased or stayed the same on any demographic or disease-related variables, or in mood or perceived quality of relationship with the carer. Whereas baseline QoL score was the strongest predictor of QoL at 20 months, the quality of relationship with the carer as perceived by the PwD was also independently a significant predictor. CONCLUSIONS: There is a degree of individual variation in QoL trajectories. Use of acetylcholinesterase-inhibiting medication appears linked to decline in QoL score, whereas positive relationships with carers play an important role in maintaining QoL in early-stage dementia.

BACKGROUND: Measures of memory awareness based on evaluative judgement and performance monitoring are often regarded as equivalent, but the Levels of Awareness Framework suggests they reflect different awareness phenomena. Examination of memory awareness among groups with differing degrees of impairment provides a test of this proposition. METHOD: Ninety-nine people with dementia (PwD), 30 people with mild cognitive impairment (PwMCI), and their relatives completed isomorphic performance monitoring and evaluative judgement measures of memory awareness and were followed up at 12 and (PwD only) 20 months. In addition to the resulting awareness indices, comparative accuracy scores were calculated using the relatives' data to establish whether any inaccuracy was specific to self-ratings. RESULTS: When making evaluative judgements about their memory in general, both PwD and PwMCI tended to overestimate their own functioning relative to informant ratings made by relatives. When monitoring performance on memory tests, PwD again overestimated performance relative to test scores, but PwMCI were much more accurate. Comparative accuracy scores indicated that, unlike PwD, PwMCI do not show a specific inaccuracy in self-related appraisals. CONCLUSIONS: The results support the proposition that awareness indices at the levels of evaluative judgement and performance monitoring should be regarded as reflecting distinct awareness phenomena.

BACKGROUND: Ideally clinical trials should use some form of randomization for allocating participants to the treatment groups under trial. As an integral part of the process of assessing the effectiveness of these treatment groups, randomization performed well can reduce, if not eliminate, some forms of bias that can be evident in non-randomized trials. Given the vast set of possible randomization methods to choose from we demonstrate a method that incorporates many of the advantages of these other methods. METHODS: A step-by-step introduction of how to use the adaptive randomization algorithm for conducting a clinical trial is given. RESULTS: The implications, effects and capabilities of using the adaptive randomization algorithm are fully demonstrated and explained using simulated data and examples from actual trials. CONCLUSIONS: This paper provides an introduction to a dynamic type of treatment allocation, which fulfills the CONSORT requirements of participants being randomly allocated whilst maintaining a level of control of the balances overall, within the stratification variables and within the strata simultaneously. Maintaining control of the imbalances within the groups is vital particularly if interim analyses are planned.

OBJECTIVE: Although it is increasingly accepted that people with dementia retain a sense of self, there is a need for empirical evidence regarding the nature of the self-concept in early stage dementia, how this changes over time and how it relates to quality of life. METHODS: Self-concept was assessed using the short form of the Tennessee Self-concept Scale in 95 individuals with early stage dementia; 63 were reassessed after 12 months, and 45 were seen again at 20 months. Participants also completed measures of mood, cognitive functioning and quality of life. Caregivers provided proxy ratings of self-concept, completed measures of symptoms and distress at symptoms and rated their own levels of stress and well-being. RESULTS: Self-ratings of self-concept were close to the average range for the standardization sample, and the distribution did not differ significantly from expected values. Although caregiver ratings were slightly lower, discrepancies were small. There were no significant changes over time in self-ratings or informant ratings or discrepancies. At Time 1, self-ratings were predicted by anxiety, depression and memory, caregiver ratings were predicted by caregiver distress and by depression in the person with dementia and discrepancies were predicted by caregiver distress. These models remained predictive at later time points. Self-rated self-concept predicted quality of life, with the relationship only partially mediated by depression and anxiety. CONCLUSIONS: Self-concept appears largely intact in early stage dementia, but in view of the association between self-concept and quality of life, a preventive approach focused on supporting self-concept may offer benefits as dementia progresses.

BACKGROUND: Lifestyle factors playing a role in the development of late-life disability may be modifiable. There is a need for robust evidence about the potential for prevention of disability through behavior change interventions. METHODS/DESIGN: This feasibility study involves the development, implementation and initial testing of a behavior change intervention in a naturalistic setting. A small-scale randomized controlled trial (RCT) will investigate the implementation of a goal-setting intervention aimed at promoting behavior change in the domains of physical and cognitive activity in the context of a community resource center for over-50s. Healthy older participants attending the center (n = 75) will be randomized to one of three conditions: control (an interview involving a general discussion about the center); goal-setting (an interview involving identification of up to five personal goals in the domains of physical activity, cognitive activity, diet and health, and social engagement); or goal-setting with mentoring (the goal-setting interview followed by bi-monthly telephone mentoring). All participants will be reassessed after 12 months. Primary outcomes are levels of physical and cognitive activity. Secondary outcomes address psychosocial (self-efficacy, mood, quality of life), cognitive (memory and executive function), and physical fitness (functional and metabolic) domains. Cost-effectiveness will also be examined. DISCUSSION: This study will provide information about the feasibility of a community-based lifestyle intervention model for over-50s and of the implementation of a goal-setting intervention for behavior change, together with initial evidence about the short-term effects of goal-setting on behavior. TRIAL REGISTRATION: Current Controlled Trials ISRCTN30080637 (http://www.controlled-trials.com).

OBJECTIVES: The process of developing and living with dementia may activate attachment feelings and behaviours in people with dementia (PwD) and their carers. By obtaining information from both PwD and carer, we aimed to provide information on the nature and concordance of attachment patterns within the dyad and to examine the relative contribution of attachment representations in PwD and carers to the well-being of both parties. METHOD: Ninety-seven PwD and their carers completed categorical and dimensional ratings of attachment. PwD also rated their self-concept, mood and quality of life. Carers rated the functional ability of PwD and neuropsychiatric symptoms and measures of subjective well-being. RESULTS: People with dementia reported more insecure than secure attachment, with the most frequently reported style being dismissive attachment. Attachment security for PwD was related to more positive self-concept and less symptoms of anxiety. Attachment was not related to quality of life in PwD, but mood and self-concept were strong predictors of quality of life. Carer attachment security was related to their psychological health. Distress at symptoms and MMSE score of the PwD were the strongest predictors of stress. There was no association between PwD and carer attachment styles; PwD working models of attachment did not predict carer well-being and vice versa. CONCLUSION: Attachment representations may be important for the psychological well-being of PwD and carers, but there was no evidence of the reciprocal nature of attachment within these dyads.

BACKGROUND: The mechanism by which the multidisciplinary approach to diabetic foot disease reduces amputation rates is unclear. Ischemia, sepsis, and necrosis represent aspects of severe diabetic foot disease amenable to intervention. In 2006, a vascular unit introduced a rapid access service for severe foot disease, augmenting the established community provision. This study aimed to determine whether concurrent changes in amputation rates were observed, and to identify areas that may have influenced outcomes. METHODS: Unit data prospectively collected during 4 years for patients with lower-limb disease were compared with data retrieved over 2 years before the foot service. Outcome measurements were major amputations, foot surgery, vascular interventions, admissions, and length of stay. RESULTS: Major amputation rates associated with diabetes peaked in 2005 at 24.7/10,000 vs. 1.07/10,000 in 2009; (relative risk = 0.043, 95% confidence interval = 0.006-0.322). The proportion of diabetic to nondiabetic amputations decreased; foot surgery rates also dropped (53.7/10,000 in 2006 vs. 7.5/10,000 in 2009). The number of open revascularization procedures decreased, but the rates of endovascular procedures remained generally constant. Hospital admission rates decreased after initially peaking, and the length of stay was unchanged (16 vs. 15.5 days in 2004 and 2009, respectively). CONCLUSIONS: The integration of a vascular unit with community care has been associated with improved outcomes for patients with diabetic foot disease. Improvements were not related to the increased number of vascular procedures or hospitalizations, but did coincide with a greater proportion of patients attending the foot unit. The referral of patients to the unit facilitates the rapid management of severe disease, reducing delays deleterious to outcomes.

Assessment of activities of daily living is an important element in the diagnosis of dementia, with research suggesting a link between functional ability and cognition. We investigated the relationship between self- and informant ratings of instrumental activities of daily living (iADL) and verbal executive functioning in early-stage dementia. A total of 96 people with early-stage Alzheimer's disease or vascular or mixed dementia and their carers completed the Functional Activities Questionnaire; people with dementia also completed a test of letter fluency. Letter fluency was associated with self-ratings of iADL, while informant ratings of iADL were associated with the age and Mini-Mental State Examination score of the person with dementia. Self-ratings of perceived functioning suggested significantly less impairment than informant ratings. Those with impaired letter fluency rated themselves as having greater difficulties in iADLs than those who performed better. People with early-stage dementia vary in their subjective level of awareness of their iADL functioning, and difficulties with language production may contribute to better awareness of iADL impairments.

OBJECTIVES: In early-stage dementia, awareness at the meta-representational level involving a person's appraisal of his/her own condition and its implications has usually been assessed by interview, but contextual factors may influence responding. We examined the utility of an indirect, vignette-based method of eliciting awareness. METHOD: Three vignettes describing early-stage dementia, established dementia and healthy ageing were used to elicit views of the problem and the kinds of advice that might be helpful for the characters depicted. Responses were obtained from 91 people with early-stage Alzheimer's, vascular or mixed dementia, 87 carers and 80 older controls. For the participants with dementia, awareness was assessed in separate in-depth interviews and rated on a five-point scale for comparison purposes. RESULTS: Participants with dementia were often able to correctly identify the problems described in the vignettes, although scoring lower than carers or controls. Participants with dementia were also able to offer advice for those depicted, although to a lesser extent than carers or controls. Ability to offer advice was greater where MMSE scores were higher. For participants with dementia, vignette scores were moderately correlated with ratings derived from interviews, and those showing limited or no awareness offered fewer items of advice than those showing some or good awareness. In addition, 29% of participants with dementia spontaneously pointed out similarities between their own condition and that of the person depicted. CONCLUSIONS: The vignette method may be useful where resources preclude the use of in-depth interviews, and may supplement in-depth interviews as part of a multi-dimensional assessment of awareness.

BACKGROUND: Insufficient attention has been paid to the influence of psychological and social factors on discrepancy-based measures of awareness. OBJECTIVES: The present study tested a biopsychosocial model of awareness in early-stage dementia by gathering evidence regarding the relative contributions of neuropsychological, individual psychological and social factors to the level of scoring on measures used to index awareness. METHOD: Awareness was assessed in relation to memory, activities of daily living and social functioning in 101 individuals with early-stage dementia participating in the Memory Impairment and Dementia Awareness (MIDAS) Study. People with dementia (PwD) and carers also completed measures of individual psychological and social variables, and PwD completed measures of neuropsychological functioning. RESULTS: Scores on discrepancy-based indices of awareness and on the self-ratings and informant ratings contributing to these indices were associated with a range of factors including neuropsychological functioning of PwD, individual traits and dispositions and current affective functioning of PwD, socio-demographic characteristics of PwD and carers, carer well-being and carer perceptions of PwD and of quality of relationship with PwD. Patterns of association varied across domains of functioning. CONCLUSIONS: The findings support the relevance of a biopsychosocial approach to understanding the factors that influence unawareness of impairment in dementia.
