Abstract
OBJECTIVE To analyze the differences in the dynamics of cognitive functions in the elderly and old people during a comprehensive neurocognitive rehabilitation program with- and without drug therapy. MATERIAL AND METHODS Ninety-six patients, aged 53-88 years, with cognitive impairment of varying degrees are divided into two groups depending on the presence/absence of drug therapy during the neurocognitive rehabilitation program. Assessment of cognitive functions was carried out twice: at the beginning and at the end of the rehabilitation program using international cognitive status assessment scales (MMSE and MoCA). RESULTS The analysis of the dynamics of cognitive functions revealed the high efficiency of the neurocognitive rehabilitation program in both groups. The results of the study demonstrate insignificant differences in the dynamics of cognitive functions in the two groups, however, a clear direct effect of drug therapy on changes in cognitive functions has not been established. An analysis of the statistical significance of the data did not reveal differences. CONCLUSIONS The study confirmed the positive dynamics of cognitive functions in the elderly and old people who underwent the neurocognitive rehabilitation program both with the use of drug therapy and without its use. The issue of the need to use drugs in the framework of this program requires further study. The results of the study can be used in planning programs of psychological, medical and social support for the elderly and old people.

Photo-Realistic Interactive Virtual Environments for Neurorehabilitation in Mild Cognitive Impairment (NeuroVRehab.PT): A Participatory Design and Proof-of-Concept Study.

Abstract
Mild cognitive impairment (MCI) is characterized by cognitive, psychological, and functional impairments. Digital interventions typically focus on cognitive deficits, neglecting the difficulties that patients experience in instrumental activities of daily living (IADL). The global conjecture created by COVID-19 has highlighted the seminal importance of digital interventions for the provision of healthcare services. Here, we investigated the feasibility and rehabilitation potential of a new design approach for creating highly realistic interactive virtual environments for MCI patients’ neurorehabilitation. Through a participatory design protocol, a neurorehabilitation digital platform was developed using images captured from a Portuguese supermarket (NeuroVRehab.PT). NeuroVRehab.PT’s main features (e.g., medium-sized supermarket, the use of shopping lists) were established according to a shopping behavior questionnaire filled in by 110 older adults. Seven health professionals used the platform and assessed its rehabilitation potential, clinical applicability, and user experience. Interviews were conducted using the think-aloud method and semi-structured scripts, and four main themes were derived from an inductive semantic thematic analysis. Our findings support NeuroVRehab.PT as an ecologically valid instrument with clinical applicability in MCI neurorehabilitation. Our design approach, together with a comprehensive analysis of the patients’ past experiences with IADL, is a promising technique to develop effective digital interventions to promote real-world functioning.

Training gains and transfer effects after mnemonic strategy training in mild cognitive impairment: A fMRI study. Int J Psychophysiol 2019; 154:15-26.

Abstract
Prior work has revealed that mnemonic strategy training (MST) can enhance memory for specific content and engages regions in the frontoparietal cognitive control network. Evidence of transfer to novel content is less clear. Here, we provide secondary analysis of functional magnetic resonance imaging (fMRI) data acquired during a randomized controlled trial that compared MST to an active education control condition in patients with amnestic mild cognitive impairment (a-MCI). In the trial, thirty participants with a-MCI were randomized to the education program (EP) or MST, where they learned to apply the technique to face-name associations during four intervening hour long training sessions. Participants underwent pre- and post-training fMRI scans, during which they encoded both the trained (i.e., those used during the four training sessions) and untrained ('novel') face-name associations. The primary cognitive outcome measures revealed significantly improved memory for both trained and novel stimuli - effects supporting near transfer of MST. Relative to pre-training, there were significant and highly similar increases in activation for both trained and novel stimuli, especially in regions associated with the frontoparietal cognitive control network bilaterally, but also in temporal areas related to social cognition and emotional processing. Critically, this pattern of activation was notably different from the EP group. Thus, the changes in activation were consistent with the strategies trained and, combined with the cognitively-based near transfer effects, suggest that MST focused on face-name association enhances performance by engaging cognitive control and social/emotional processing. Finally, our data indicated that our MST is a relevant and efficient intervention to a-MCI.

Abstract
People with dementia are often inevitably confronted with various difficulties with social interaction and communication, which is a core problem that can be improved with rehabilitative support, thus improving their quality of life. The authors propose rehabilitative support using communication via activities; co-beneficial relationship-based rehabilitation, which emphasizes the following 3 points: support for people with dementia to improve social reserves, which is the ability to overcome the decline in social cognition; support for family members for improving cognitive empathy, which is the ability to analyze the background of others’ behaviors and speech; and the involvement of the practitioner to supervise and empower them. The process of intervention is as follows: (1) selecting activities for collaboration; (2) sharing information on their current situation including declined abilities; (3) enhancing cognitive empathy through dementia education; (4) designing the intervention measures together; and (5) practice and feedback. Living with dementia involves a continuous process of coping with various challenges in daily living, however, the process of effectively managing these challenges is one of the ways to improve the quality of life of people with dementia and their family members.

Cognitive and Brain Activity Changes After Mnemonic Strategy Training in Amnestic Mild Cognitive Impairment: Evidence From a Randomized Controlled Trial. Front Aging Neurosci 2018; 10:342.

Abstract
Background: Mnemonic strategy training (MST) has been shown to improve cognitive performance in amnestic mild cognitive impairment (a-MCI), however, several questions remain unresolved. The goal of the present study was to replicate earlier pilot study findings using a randomized controlled design and to evaluate transfer effects and changes in brain activation. Methods: Thirty patients with a-MCI were randomized into MST or education program. At baseline, participants completed clinical and neuropsychological assessments as well as structural and functional magnetic resonance imaging (fMRI). Interventions were administered individually and comprised four sessions, over 2 weeks. MST taught patients to use a three-step process to learn and recall face-name associations. Post-treatment assessment included fMRI, a separate face-name association task, neuropsychological tests, and measures of metamemory. Behavioral (i.e., non-fMRI) measures were repeated after one and 3-months. Results: Participants in the MST condition showed greater improvement on measures of face-name memory, and increased associative strategy use; effects that were accompanied by increased fMRI activation in the left anterior temporal lobe. While all participants reported greater contentment with their everyday memory following intervention, only the MST group reported significant improvements in their memory abilities. There was no clear indication of far-transfer effects to other neuropsychological tests. Conclusion: Results demonstrate that patients with a-MCI not only show stimulus specific benefits of MST, but that they appear capable of transferring training to at least some other cognitive tasks. MST also facilitated the use of brain regions that are involved in face processing, episodic and semantic memory, and social cognition, which are consonant with the cognitive processes engaged by training.

Abstract
INTRODUCTION Given the limited effectiveness of pharmacological treatments, non-pharmacological interventions in neurodegenerative diseases have gained increasing attention in recent years and telerehabilitation has been proposed as a cognitive rehabilitation strategy. The purpose of this systematic review is to examine the evidence for the efficacy of cognitive telerehabilitation interventions compared with face-to-face rehabilitation in patients with mild cognitive impairment, Alzheimer's disease and frontotemporal dementia. METHODS In accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a systematic search of the Medline database was conducted. Out of 14 articles assessed for eligibility, five studies were identified, three in participants with mild cognitive impairment or Alzheimer's disease, two in patients with primary progressive aphasia. RESULTS The Physiotherapy Evidence Database scale was used to assess the methodological quality of four out of five studies included in this systematic review, with only one report receiving a high-quality rating. Effect-size analysis evidenced positive effects of telerehabilitation interventions, comparable with those reported for face-to-face rehabilitation. DISCUSSION The available evidence for the effectiveness of cognitive telerehabilitation is limited, and the quality of the evidence needs to be improved. The systematic review provides preliminary evidence suggesting that cognitive telerehabilitation for neurodegenerative disease may have comparable effects as conventional in-person cognitive rehabilitation.

Abstract
ObjectivesResearch shows that cognitive rehabilitation (CR) has the potential to improve goal performance and enhance well-being for people with early stage Alzheimer’s disease (AD). This single subject, multiple baseline design (MBD) research investigated the clinical efficacy of an 8-week individualised CR intervention for individuals with early stage AD.MethodsThree participants with early stage AD were recruited to take part in the study. The intervention consisted of eight sessions of 60–90 minutes of CR. Outcomes included goal performance and satisfaction, quality of life, cognitive and everyday functioning, mood, and memory self-efficacy for participants with AD; and carer burden, general mental health, quality of life, and mood of carers.ResultsVisual analysis of MBD data demonstrated a functional relationship between CR and improvements in participants’ goal performance. Subjective ratings of goal performance and satisfaction increased from baseline to post-test for three participants and were maintained at follow-up for two. Baseline to post-test quality of life scores improved for three participants, whereas cognitive function and memory self-efficacy scores improved for two.ConclusionsOur findings demonstrate that CR can improve goal performance, and is a socially acceptable intervention that can be implemented by practitioners with assistance from carers between sessions. This study represents one of the promising first step towards filling a practice gap in this area. Further research and randomised-controlled trials are required.

Abstract
There is a growing body of knowledge about the use of compensatory memory aids in memory rehabilitation, but relatively few controlled trials on how to train the use of such aids. This study investigated the effects of systematic training in the use of compensatory memory aids on everyday memory functioning within a Memory Aids Service. In a controlled clinical trial, a comparison was made between treatment participants and waiting list controls. Participants had everyday memory problems secondary to progressive or non-progressive neurological conditions. Following baseline assessment and goal setting, treatment participants underwent three training sessions, in which memory aids were matched to goals, across a six week period, with a follow-up assessment 12 weeks later. Outcome was measured by a goal attainment diary, neuropsychological test performance, psychosocial questionnaires and a problem solving inventory. There was a significant treatment effect of training on the goal attainment diary but only at 12 weeks follow-up. A post-hoc analysis indicated that treatment was effective for participants with a non-progressive condition but not for participants with a progressive condition. We conclude that a Memory Aids Service can be beneficial for patients with a non-progressive neurological condition, and make suggestions that might inform future applications of memory aids with those who have a progressive neurological disorder.

Abstract
Introduction To date, potential difficulties that people with cognitive deficits meet in everyday life are relatively well known, but in which activities mastery is desired, and why, is less researched. The aim of this study was to develop deeper knowledge about activities that people with cognitive deficits want to continue mastering in everyday life and the reasons why these activities were desired. Method In the frame of a scoping study, articles were gathered and charted. Sixteen qualitative studies were selected as meeting the aim of the study and analyzed with a descriptive-interpretative method. Findings The analysis of the studies showed that the desired activities conveyed social values or independence, supported significant roles, diminished negative influence on other people, and increased health and safety. Linkages, in the form of dependencies between the desired activities, were also identified. Conclusion When planning for interventions for facilitating everyday activities, for example with technology, it is beneficial to consider both safety and values that are more closely related to meaningfulness and wellbeing. Most difficult activities were identified as hindering outdoor activities, and targeting those activities might be most valuable for enabling active everyday lives for this group.

Abstract
Background. Cognitive interventions for older persons that may diminish the burden of cognitive problems and could delay conversion to dementia are of great importance. The underlying mechanisms of such interventions might be psychological compensation and neuronal plasticity. This review provides an overview of the literature concerning the evidence that cognitive interventions cause brain activation changes, even in damaged neural systems.
Method. A systematic search of the literature was conducted in several international databases, Medline, Embase, Cinahl, Cochrane, and Psychinfo. The methodological quality was assessed according to the guidelines of the Dutch Institute for Health Care Improvement (CBO). Results. Nineteen relevant articles were included with varied methodological quality. All studies were conducted in diverse populations from healthy elderly to patients with dementia and show changes in brain activation after intervention. Conclusions. The results thus far show that cognitive interventions cause changes in brain activation patterns. The exact interpretation of these neurobiological changes remains unclear. More study is needed to understand the extent to which cognitive interventions are effective to delay conversion to dementia. Future studies should more explicitly try to relate clinically significant improvement to changes in brain activation. Long-term follow-up data are necessary to evaluate the stability of the effects.

Abstract
[Purpose] The purpose of this study was to investigate the effect of cognitive
rehabilitation including tasks of cognitive training on performance of everyday activities
in elderly people with early-stage Alzheimer’s disease. [Subjects and Methods] Forty-three
elderly people (15 men, 28 women) with a diagnosis of Alzheimer’s disease who had a
Mini-Mental State Examination (MMSE) score of 18 or above were randomly assigned to two
groups: the cognitive rehabilitation group (experimental) and control group. This study
used a randomized controlled trial design. Cognitive rehabilitation is consisted of 8
sessions, each lasting 60 minutes (individual 30 min, group 30 min). The eight weekly
individual sessions of cognitive rehabilitation were performed consisting of an
individualized intervention focusing on a personally meaningful goal. The eight weekly
group sessions involved practicing time-and-place orientation, matching faces and names,
and learning memory and sustaining attention. [Results] Significant improvements were
observed in rating of occupation performance and satisfaction, Quality of Life in
Alzheimer’s Disease (QOL-AD), and the orientation subscale of the MMSE in the experimental
group, whereas participants in the control group did not show any significant difference
in any tests between before and after the intervention. [Conclusion] Cognitive
rehabilitation including tasks of cognitive training is an effective intervention for
improving performance and satisfaction with respect to activities of daily living and
specific cognitive functions.

Attention-Deficit/Hyperactivity Disorder (ADHD), a neuropsychiatric condition characterized by attention and impulsivity problems, is one of the most common behavioral disorders. The first line of treatment for ADHD is psychostimulant medication, but this has limited effectiveness, particularly in adults, and is often associated with adverse side-effects. Thus, it is imperative that new non-pharmaceutical approaches to treatment are developed. This study aims to evaluate the impact of a non-pharmacological Self-Alert Training (SAT) intervention on ADHD symptom prevalence, psychological and cognitive functioning, and on everyday functional impairment in adults with ADHD. Fifty-one adult participants with a current diagnosis of ADHD were randomized to either SAT or a Control Training (CT) program. They were assessed at baseline, immediately following the 5-week training period, and after 3-months using ADHD symptoms scales, as well as a series of neuropsychological tests and psychological questionnaires. Subjective ratings of everyday life attention and memory problems were also collected. The SAT group showed significant improvements in ADHD inattentive and impulsive symptoms, depressive symptoms and in self-efficacy ratings compared to the CT group at both post-training and at the 3-month assessment. Pre-post improvements in SAT participants on untrained cognitive tasks measuring selective attention and executive functions were also observed. Finally, the SAT group reported improved subjective ratings of everyday life attention at both assessment points. This pattern of results suggests that SAT may be beneficial in treating ADHD symptoms as well as psychological and cognitive impairments in adult ADHD. A large-scale randomized controlled trial (RCT) is needed.

Abstract
OBJECTIVE Mild dementia is marked by deficits in cognition and everyday activities. However, few studies have translated findings from both areas of functioning into effective cognitive rehabilitation. The purpose of this review was to critically evaluate the existing literature on the type and success of interventions and on their extent of use of cognitive theory. Given the limited evidence base in this population, further insights were obtained from studies on mild cognitive impairment (MCI), which involves fewer cognitive and everyday functioning problems than dementia. METHODS From the literature searches, 11 studies on mild dementia and three studies on MCI were obtained. Studies were only included if the interventions either targeted instrumental activities of daily living or activities of daily living directly or as an outcome measure or if the interventions focused on real-life aspects not captured in the standardised daily activities. For inclusion, patients needed a diagnosis of dementia or MCI, and Mini-Mental State Examination scores had to be above 17 for mild dementia. RESULTS The majority of interventions indicated improved everyday activity performance in early dementia and MCI. Focusing on individual, as opposed to global, daily activities appeared to be an important determinant of intervention success in mild dementia but not in MCI. However, few attempts had been made to develop interventions grounded in evidence-based models. CONCLUSIONS This review highlights the need for further translation of the understanding of cognitive and everyday activity deficits into successful interventions for daily activities in MCI and early dementia. Hence, research is first required to link individual activities with cognitive domains.

Abstract
The main goal of this study was to evaluate the impact of a cognitive rehabilitation programme on 12 behavioural and psychological symptoms of dementia (BPSD) in patients with mild to moderate Alzheimer's disease (AD). This six-month single-blind block-randomised cross-over controlled study was conducted with 15 mild to moderate AD participants and their caregivers. All participants received a four-week home-based cognitive rehabilitation programme to learn/re-learn an instrumental activity of daily living. They were assessed up until three months following the end of the intervention. The Neuropsychiatric Inventory (NPI-12) was employed to evaluate patients' BPSD at seven assessment points during the course of the study. A general linear mixed model analysis performed on the NPI data revealed that aberrant motor behaviours (AMB) increased significantly more in the treatment condition than in the control condition. In addition, both groups registered a significant reduction of delusional symptoms during the second half of the study. Employing a multi-symptom approach to assess participants' BPSD, this cross-over randomised controlled study showed that an individualised cognitive rehabilitation intervention was generally well-tolerated by mild to moderate AD patients. Future cognitive rehabilitation studies conducted with this population should pay attention to AMB symptom changes.

Abstract
OBJECTIVES The Long Lasting Memories (LLM) program concerns a newly integrated platform which combines cognitive exercises with physical activity within the context of advanced technologies. The main objective of this study was to present the preliminary results that determine the possible effectiveness of the LLM program in the improvement of cognitive functions and symptoms of depression in healthy elderly and subjects with mild cognitive impairment (MCI). METHOD Fifty healthy and MCI subjects participated in the study. All of them received one hour's physical training and 35 minutes' cognitive training, 3 times a week, during the 12 weeks of the program. Before and after the intervention all participants were assessed using a battery of neuropsychological tests. RESULTS The results showed a significant improvement after the LLM training in global cognitive function, in verbal memory, in attention, in episodic memory and symptoms of depression. CONCLUSION This study indicates that LLM is a promising solution for older adults with and without cognitive impairment, maintaining their wellbeing with few professional and technical requirements.

Abstract
Although some studies point to cognitive stimulation as a beneficial therapy for older adults with cognitive impairments, this area of research and practice is still lacking dissemination and is underrepresented in many countries. Moreover, the comparative effects of different intervention durations remain to be established and, besides cognitive effects, pragmatic parameters, such as cost-effectiveness and experiential relevance to participants, are seldom explored. In this work, we present a randomized controlled wait-list trial evaluating 2 different intervention durations (standard = 17 vs brief = 11 sessions) of a cognitive stimulation program developed for older adults with cognitive impairments with or without dementia. 20 participants were randomly assigned to the standard duration intervention program (17 sessions, 1.5 months) or to a wait-list group. At postintervention of the standard intervention group, the wait-list group crossed over to receive the brief intervention program (11 sessions, 1 month). Changes in neuropsychological, functionality, quality of life, and caregiver outcomes were evaluated. Experience during intervention and costs and feasibility were also evaluated. The current cognitive stimulation programs (ie, standard and brief) showed high values of experiential relevance for both intervention durations. High adherence, completion rates, and reasonable costs were found for both formats. Further studies are needed to definitively establish the potential efficacy, optimal duration, cost-effectiveness, and experiential relevance for participants of cognitive intervention approaches.

Abstract
Cognitive training is an emergent approach that has begun to receive increased attention in recent years as a non-pharmacological, cost-effective intervention for Alzheimer’s disease (AD). There has been increasing behavioral evidence regarding training-related improvement in cognitive performance in early stages of AD. Although these studies provide important insight about the efficacy of cognitive training, neuroimaging studies are crucial to pinpoint changes in brain structure and function associated with training and to examine their overlap with pathology in AD. In this study, we reviewed the existing neuroimaging studies on cognitive training in persons at risk of developing AD to provide an overview of the overlap between neural networks rehabilitated by the current training methods and those affected in AD. The data suggest a consistent training-related increase in brain activity in medial temporal, prefrontal, and posterior default mode networks, as well as increase in gray matter structure in frontoparietal and entorhinal regions. This pattern differs from the observed pattern in healthy older adults that shows a combination of increased and decreased activity in response to training. Detailed investigation of the data suggests that training in persons at risk of developing AD mainly improves compensatory mechanisms and partly restores the affected functions. While current neuroimaging studies are quite helpful in identifying the mechanisms underlying cognitive training, the data calls for future multi-modal neuroimaging studies with focus on multi-domain cognitive training, network level connectivity, and individual differences in response to training.

Abstract
There is enormous interest in designing training methods for reducing cognitive decline in healthy older adults. Because it is impaired with aging, multitasking has often been targeted and has been shown to be malleable with appropriate training. Investigating the effects of cognitive training on functional brain activation might provide critical indication regarding the mechanisms that underlie those positive effects, as well as provide models for selecting appropriate training methods. The few studies that have looked at brain correlates of cognitive training indicate a variable pattern and location of brain changes--a result that might relate to differences in training formats. The goal of this study was to measure the neural substrates as a function of whether divided attentional training programs induced the use of alternative processes or whether it relied on repeated practice. Forty-eight older adults were randomly allocated to one of three training programs. In the single repeated training, participants practiced an alphanumeric equation and a visual detection task, each under focused attention. In the divided fixed training, participants practiced combining verification and detection by divided attention, with equal attention allocated to both tasks. In the divided variable training, participants completed the task by divided attention, but were taught to vary the attentional priority allocated to each task. Brain activation was measured with fMRI pre- and post-training while completing each task individually and the two tasks combined. The three training programs resulted in markedly different brain changes. Practice on individual tasks in the single repeated training resulted in reduced brain activation whereas divided variable training resulted in a larger recruitment of the right superior and middle frontal gyrus, a region that has been involved in multitasking. The type of training is a critical factor in determining the pattern of brain activation.

Abstract
This was an exploratory study, with the purpose of developing and piloting an intervention for people with mild cognitive impairment (MCI) and their family members using cognitive rehabilitation. A case series design was used with pre- and post-intervention and 3-month follow-up outcome measures. Five participants (two males, three females; mean age 75 years) with a diagnosis of MCI attended the memory clinic with a family member. Intervention consisted of six to eight individual sessions of cognitive rehabilitation consisting of personalized interventions to address individually relevant goals delivered weekly. The main rehabilitation strategies utilized were external aids, personal diary, face-name association, relaxation, and encouraging participants to develop habits and routines. The primary outcome measure was goal attainment as assessed by Goal Attainment Scaling. Secondary outcome measures included measures of memory, anxiety, depression, and activities of daily living. Qualitative data were collected post-intervention by interview. Post-intervention 84% of the goals were attained, with 68% maintained at a 3-month follow-up. Mean anxiety and depression scores decreased during the intervention. No significant changes were recorded on a test of memory. The findings suggest that the strongest effect was in relation to compensatory strategies for prospective and episodic memory deficits. Feedback from participants during qualitative interviews indicated that they found strategies useful and implemented them in their daily routines. The findings support the use of a dyadic cognitive rehabilitation intervention for people with MCI and memory difficulties.

Abstract
In recent years, cognitive difficulties associated with normal aging and dementia have been receiving increased attention from both public and scientific communities. With an increase in overall lifespan, promoting healthy cognition has become a priority and a necessity for minimizing and preventing individual and societal burdens associated with cognitive dysfunctions in the elderly. The general awareness concerning the efficacy of preventive (e.g., lifestyles) and palliative treatment strategies of cognitive impairments, related to either healthy or unhealthy trajectories in cognitive aging, is continuously rising. There are several therapeutic strategies which can be broadly classified as either pharmacological or non-pharmacological/psychosocial. In face of the modest evidence for success of pharmacological treatments, especially for dementia related impairments, psychosocial interventions are progressively considered as a complementary treatment. Despite the relative spread of psychosocial interventions in clinical settings, research in this area is rather scarce with evidence for success of these therapies remaining controversial. In this work we provide an evidence based perspective on cognitive intervention(s) for healthy aging, pre-dementia (mild cognitive impairment), and dementia populations. Current evidence and future directions for improving cognitive functions in the elderly are discussed as well.

Abstract
Working memory is a cognitive process that is particularly vulnerable to decline with age. The current study sought to evaluate the efficacy of a working memory training scheme in improving memory in a group of older adults. A 5-week online training scheme was designed to provide training in the main components of Baddeley's (2000) working memory model, namely auditory and visuospatial short-term and working memory. A group of older adults aged between 64 and 79 were randomly assigned to a trainee (n = 19) or control (n = 17) group, with trainees engaging in the adaptive training scheme and controls engaging in a non-adaptive version of the program. Before and after training and at 3- and 6-month follow-up sessions, trainees and controls were asked to complete measures of short-term and working memory, long-term episodic memory, subjective ratings of memory, and attention and achievement of goals set at the beginning of training. The results provided evidence of an expansion of auditory short-term memory span, which was maintained 6 months later, and transfer to long-term episodic memory but no evidence of improvement in working memory capacity per se. A serendipitous and intriguing finding of a relationship between time spent training, psychological stress, and training gains provided further insight into individual differences in training gains in older adults.

Abstract
BACKGROUND People with Alzheimer disease (AD) are capable of new learning when cognitive support is provided, suggesting that there is plasticity even in a degenerating brain. However, it is unclear how a cognition-focused intervention operates on a neural level. OBJECTIVE The present study examined the effects of cognitive rehabilitation (CR) on memory-related brain activation in people with early-stage AD, as measured by functional magnetic resonance imaging (fMRI). METHODS A total of 19 participants either received 8 weeks of CR treatment (n = 7) or formed a control group (n = 12). We scanned participants pretreatment and posttreatment while they learned and recognized unfamiliar face-name pairs. RESULTS Following treatment, the CR group showed higher brain activation during recognition of face-name pairs in the left middle and inferior frontal gyri, the left insula, and 2s regions in the right medial parietal cortex. The control group showed decreased activation in these areas during recognition after the intervention period. Neither group showed an activation change during encoding. Behavioral performance on face-name learning did not improve for either group. CONCLUSIONS We suggest that CR may have operated on the process of recognition through partial restoration of function in frontal brain areas that are less compromised in early-stage AD and that physiological markers may be more sensitive indicators of brain plasticity than behavioral performance.

Abstract
An increasing number of studies have relied on brain imaging to assess the effects of cognitive training in healthy aging populations and in persons with early Alzheimer's disease or mild cognitive impairment (MCI). At the structural level, cognitive training in healthy aging individuals has been associated with increased brain volume, cortical thickness, and density and coherence of white matter tracts. At the functional level, task-related brain activation (using fMRI and PET) and fluorodeoxyglucose positron emission tomography (FDG-PET) were found to be sensitive to the effects of training. In persons with MCI, cognitive training increased brain metabolism and task-related brain activation, whereas healthy older adults showed patterns of increased and decreased activation. Further studies are required to generalize these findings to larger groups and to investigate more diverse training protocols. Research will also need to address important methodological issues regarding the use of biomarkers in cognitive aging, including reliability, clinical validity, and relevance to the pathophysiological process.

Abstract
Non-pharmacological intervention of memory difficulties in healthy older adults, as well as those with brain damage and neurodegenerative disorders, has gained much attention in recent years. The two main reasons that explain this growing interest in memory rehabilitation are the limited efficacy of current drug therapies and the plasticity of the human central nervous and the discovery that during aging, the connections in the brain are not fixed but retain the capacity to change with learning. Moreover, several studies have reported enhanced cognitive performance in patients with neurological disease, following non-invasive brain stimulation [i.e., repetitive transcranial magnetic stimulation and transcranial direct current stimulation to specific cortical areas]. The present review provides an overview of memory rehabilitation in individuals with mild cognitive impairment and in patients with Alzheimer’s disease with particular regard to cognitive rehabilitation interventions focused on memory and non-invasive brain stimulation. Reviewed data suggest that in patients with memory deficits, memory intervention therapy could lead to performance improvements in memory, nevertheless further studies need to be conducted in order to establish the real value of this approach.

Abstract
Older adults with cognitive impairments often have difficulty performing instrumental activities of daily living (IADLs). Prompting technologies have gained popularity over the last decade and have the potential to assist these individuals with IADLs in order to live independently. Although prompting techniques are routinely used by caregivers and health care providers to aid individuals with cognitive impairment in maintaining their independence with everyday activities, there is no clear consensus or gold standard regarding prompt content, method of instruction, timing of delivery, or interface of prompt delivery in the gerontology or technology literatures. In this paper, we demonstrate how cognitive rehabilitation principles can inform and advance the development of more effective assistive prompting technologies that could be employed in smart environments. We first describe cognitive rehabilitation theory (CRT) and show how it provides a useful theoretical foundation for guiding the development of assistive technologies for IADL completion. We then use the CRT framework to critically review existing smart prompting technologies to answer questions that will be integral to advancing development of effective smart prompting technologies. Finally, we raise questions for future exploration as well as challenges and suggestions for future directions in this area of research.

Abstract
Although language rehabilitation in patients with primary progressive aphasia (PPA) is recommended, rehabilitation studies in this clinical syndrome are scarce. Specifically, in relation to semantic dementia (SD), few studies have shown the possibility of lexical relearning. Objective To analyze the effectiveness of rehabilitation for lexical reacquisition in SD. Methods Three SD patients were submitted to training for lexical reacquisition based on principles of errorless learning. Comparisons between naming performance of treated items (pre and post-training) and non-treated items of the Boston Naming Test (BNT) were made. Results All patients improved their performance in naming treated words after intervention. However, decline in performance in naming of non-treated items was observed. Case 1 named zero items at baseline while her performance post-training was 29.4% correct responses without cueing, and 90.7% correct with and without cueing. Case 2 named 6.9% of items correctly at baseline and his performance in post-training was 52.9% without cueing and 87.3%, with and without cueing. Case 3 named zero items at baseline and his performance in post-training was 100% correct responses without cueing. Considering the performance in naming the non-treated items of the BNT, the percentages of correct responses in the first evaluation and in the re-evaluation, respectively were: 16.7% and 8.3% (case 1; 14 month-interval); 26.7% and 11.6% (case 2; 18 month-interval) and 11.6% and 8.3% (case 3; 6 month-interval). Conclusions The reacquisition of lost vocabulary may be possible in SD despite progressive semantic deterioration.

Abstract
OBJECTIVES To provide evidence regarding the clinical efficacy of cognitive rehabilitation (CR) in early-stage Alzheimer disease (AD). DESIGN Single-blind randomized controlled trial comparing CR with relaxation therapy and no treatment. SETTING Outpatient, community-based setting. PARTICIPANTS Sixty-nine individuals (41 women, 28 men; mean age 77.78 years, standard deviation 6.32, range = 56-89) with a diagnosis of AD or mixed AD and vascular dementia and a Mini-Mental State Examination score of 18 or above, and receiving a stable dose of acetylcholinesterase-inhibiting medication. Forty-four family carers also contributed. INTERVENTION Eight weekly individual sessions of CR consisting of personalized interventions to address individually relevant goals supported by components addressing practical aids and strategies, techniques for learning new information, practice in maintaining attention and concentration, and techniques for stress management. MEASUREMENTS The primary outcomes were goal performance and satisfaction, assessed using the Canadian Occupational Performance Measure. Questionnaires assessing mood, quality of life and career strain, and a brief neuropsychological test battery were also administered. A subset of participants underwent functional magnetic resonance imaging (fMRI). RESULTS CR produced significant improvement in ratings of goal performance and satisfaction, whereas scores in the other two groups did not change. Behavioral changes in the CR group were supported by fMRI data for a subset of participants. CONCLUSIONS The findings support the clinical efficacy of CR in early-stage AD. CR offers a means of assisting people with early-stage AD and their families in managing the effects of the condition.
