Enhancing Outcomes in Alzheimer's Disease: Exploring the Effects of a Diversified Rehabilitation Program Combined with Donepezil on Apathy, Cognitive Function, and Family Caregiver Burden.

BACKGROUND AND OBJECTIVE: Alzheimer's disease is a progressive neurodegenerative disorder characterized by cognitive decline, behavioral changes, and functional impairments. Apathy, a common symptom in Alzheimer's disease, refers to a lack of motivation, interest, and emotional responsiveness. It can significantly impact patients' quality of life and increase caregiver burden. This study aimed to determine the effects of a diversified rehabilitation program combined with donepezil on apathy, cognitive function, and family caregiver burden of Alzheimer's disease patients. METHODS: A total of 105 Alzheimer's disease patients treated at our hospital between January 2020 and January 2023 were selected and analyzed retrospectively. They were assigned to the control group (n = 50) or the observation group (n = 55). The two groups did not differ in terms of general data such as age and sex. All patients were treated with donepezil orally. The control group was given routine nursing, whereas the observation group was given a diversified rehabilitation program intervention, including cognitive training and emotional support. The Hasegawa's dementia scale, mini-mental state examination, and Montreal cognitive assessment scale were adopted to evaluate the cognitive function of the two groups before and after treatment. A caregiver burden scale, the Zarit Burden Interview (ZBI) and the Apathy Evaluation Scale Informant version (AES-I) were used to evaluate the caregiver burden and apathy of the two groups. RESULTS: A significantly higher overall response rate to treatment was found in the observation group (94.55%) than in the control group (80.00%) (p = 0.024). After treatment, scores on the Hasegawa's dementia scale, mini-mental state examination, and Montreal cognitive assessment scale of the two groups increased to varying degrees, with greater increases in the observation group than in the control group (p < 0.05). The ZBI and AES-I scores of the two groups decreased to different degrees after treatment, with greater decreases in the observation group than in the control group (p < 0.05). CONCLUSION: A diversified rehabilitation program combined with donepezil can substantially alleviate the apathy of Alzheimer's disease patients, improve their cognitive function, and reduce the burden on their families.

Physical Exercise and Alzheimer's Disease: Effects on Pathophysiological Molecular Pathways of the Disease.

Alzheimer's disease (AD), the most common form of neurodegenerative dementia in adults worldwide, is a multifactorial and heterogeneous disorder characterized by the interaction of genetic and epigenetic factors and the dysregulation of numerous intracellular signaling and cellular/molecular pathways. The introduction of the systems biology framework is revolutionizing the study of complex diseases by allowing the identification and integration of cellular/molecular pathways and networks of interaction. Here, we reviewed the relationship between physical activity and the next pathophysiological processes involved in the risk of developing AD, based on some crucial molecular pathways and biological process dysregulated in AD: (1) Immune system and inflammation; (2) Endothelial function and cerebrovascular insufficiency; (3) Apoptosis and cell death; (4) Intercellular communication; (5) Metabolism, oxidative stress and neurotoxicity; (6) DNA damage and repair; (7) Cytoskeleton and membrane proteins; (8) Synaptic plasticity. Moreover, we highlighted the increasingly relevant role played by advanced neuroimaging technologies, including structural/functional magnetic resonance imaging, diffusion tensor imaging, and arterial spin labelling, in exploring the link between AD and physical exercise. Regular physical exercise seems to have a protective effect against AD by inhibiting different pathophysiological molecular pathways implicated in AD.

Regular Physical Exercise Modulates Iron Homeostasis in the 5xFAD Mouse Model of Alzheimer's Disease.

Dysregulation of brain iron metabolism is one of the pathological features of aging and Alzheimer's disease (AD), a neurodegenerative disease characterized by progressive memory loss and cognitive impairment. While physical inactivity is one of the risk factors for AD and regular exercise improves cognitive function and reduces pathology associated with AD, the underlying mechanisms remain unclear. The purpose of the study is to explore the effect of regular physical exercise on modulation of iron homeostasis in the brain and periphery of the 5xFAD mouse model of AD. By using inductively coupled plasma mass spectrometry and a variety of biochemical techniques, we measured total iron content and level of proteins essential in iron homeostasis in the brain and skeletal muscles of sedentary and exercised mice. Long-term voluntary running induced redistribution of iron resulted in altered iron metabolism and trafficking in the brain and increased iron content in skeletal muscle. Exercise reduced levels of cortical hepcidin, a key regulator of iron homeostasis, coupled with interleukin-6 (IL-6) decrease in cortex and plasma. We propose that regular exercise induces a reduction of hepcidin in the brain, possibly via the IL-6/STAT3/JAK1 pathway. These findings indicate that regular exercise modulates iron homeostasis in both wild-type and AD mice.

The Role of the Family in the Care of Alzheimer Patients.

According to the World Health Organisation (WHO 2002), people's life expectancy worldwide is continuously growing, and on the one hand, that is one of the greatest triumphs of humanity to date. But at the same time, it is also one of the most important challenges as the aging of the population raises economic and social requirements in all countries.

Effects of the online computerized cognitive training program BEYNEX on the cognitive tests of individuals with subjective cognitive impairment and Alzheimer's disease on rivastigmine therapy

Background/aim: Clinical trials conducted on the efficacy of computerized cognitive training (CCT) programs have not led to any important breakthroughs. CCT is a safe and inexpensive approach, but its efficacy in patients on rivastigmine therapy has not been evaluated. This study aims to compare effects of CCT and examines rivastigmine to determine whether CCT has any further contributions to make. Materials and methods: Sixty individuals with subjective memory complaint (SCI) and 60 individuals with early stage Alzheimer's dementia (AD) were subjected to the Montreal Cognitive Assessment (MoCA), Cambridge Cognition (CANTAB tests: MOT, PRM, DMS, SWM, PAL, RTI), and Bayer-ADL. After screening patients who were diagnosed with AD, we started rivastigmine patch treatment (10 cm2 = 9.5 mg). The SCI and AD groups were randomly divided, and one each of the SCI and AD groups were accessed using BEYNEX, a web-based program. After a minimum of at least 1200 min of use, the diagnostic tests were repeated. Results: The AD groups' MoCA scores of the BEYNEX-practicing group demonstrated meaningfully increase, whereas they decreased in the control group, and the Bayer-ADL scores indicated improvement in ADL. The CANTAB tests both in SCI and AD and in groups using BEYNEX showed positive improvement in MOT, DMS, and PAL data. Conclusion: This study is a rare example that focuses on both groups with SCI and AD. The efficacy of CCT varies across cognitive domains and shows significant efficacy for AD but small improvements in cognitively healthy older adults. In future studies, integration with a smart learning algorithm may lead to interesting observations on which parameters are more sensitive to change under long-term use of CCT in a large number of subjects.

Why Not a Global Postural Reeducation as an Alternative Therapy Applied to Alzheimer's Patients in Nursing Homes? A Pioneer Randomized Controlled Trial.

INTRODUCTION: The classical gymnastics has always given great importance to exercises of -rachis extension and abduction of the arms during deep inhalation to acquire a greater -thoracic capacity. OBJECTIVE: The aim of this study is to organize the concentration and the self-limited capacity of patients with Alzheimer's disease (AD) thanks to the physical and -respiratory exercise modalities of global postural reeducation. DESIGN: A randomized controlled trial was conducted. SETTING: Nursing homes. PARTICIPANTS: Patients with probable AD diagnosis. INTERVENTION: The global postural reeducation method (GPR) was implemented for a total of 72 treatment sessionswith a frequency of 3 times a week, for 24 weeks consecutively. MAIN OUTCOME MEASURES: The Neuropsychiatric Inventory, Mini Mental State Examination, Geriatric Depression Scale, Quality of Life in Alzheimer's Disease and Tinetti Scale and respiratory rate frequency (RSP/F) were applied. RESULTS: Ninety elderly people participated in this study, precisely 50 women and 40 men aged 67-92 years (mean age = 81.17, SD = 5.24). The therapy had a significant effect on the difference between groups in all the outcomes (p < 0.05 in all cases) with a large effect size with exception of the RSP/F (p > 0.05). CONCLUSION: This study demonstrated a very good tolerance rate on behalf of the significant results achieved.

Improving Engagement of Mild to Moderate Dementia Alzheimer's Disease Patients Using Evidence-Based Visual Cognitive Stimulation Exercises.

INTRODUCTION: Different studies have proven the effectiveness of cognitive stimulation (CS) for people with mild to moderate dementia, but further research is needed to gain insight into how CS interventions should be designed and developed. OBJECTIVES: The objective of this study was to gather and analyze data about the development of a series of CS sessions with Alzheimer's disease (AD) patients, to gain insight into how different individuals engage to different CS activities. METHODS: 24 AD patients with mild to moderate dementia (GDS = 4 and 5) participated in the study. Twelve different sessions were held with a different stimulation exercise each. Information about the achievement and engagement for each of the exercises were recorded for each patient. RESULTS: A significant correlation was found between the global engagement and the GDS level, and between engagement and gender (and also with educational level) for one of the exercises. These results may be useful for designing CS sessions depending on the composition of the group. For example, five exercises got very different engagement results when comparing patients with GDS = 4 and GDS = 5; if the session group consists of patients with both GDS levels, these kinds of exercises should be avoided to gain homogeneity in the engagement and prevent discouragement. CONCLUSIONS: The type and characteristics of CS exercises have an impact on the engagement level of AD patients with mild to moderate dementia. Further studies are necessary to better understand which characteristics of the exercises affect the engagement of the patient according to their particularities. This kind of study may help the design of CS sessions and improve the results obtained.

Efficacy of Cognitive Rehabilitation in Alzheimer Disease: A 1-Year Follow-Up Study.

INTRODUCTION: The benefit of cognitive rehabilitation (CR) for patients with early-stage Alzheimer disease (AD) remains difficult to assess. METHOD: An observational, prospective study was conducted in a sample of 52 patients with AD included in a clinical, individualized CR program. Cognitive rehabilitation consisted of 1 weekly session during 3 months at home, followed by 1 monthly contact for 9 months. Rehabilitation techniques were used by experienced therapists to adapt activities important for the patient. Evaluation of patient's dependence in activities and objective and subjective caregiver's burden was performed with a research quantitative scale immediately after the intervention and at 6-month and 1-year follow-up. RESULTS: Analyses with repeated measure analysis of variance showed decreased patient's dependence for adapted activities at 3 months, 6 months, and 1 year. Objective and subjective percentage of caregiver's burden was also decreased at all evaluations with our research functional scale, while there was no change on Zarit's burden scale. Global cognition slightly decreased over 1 year. CONCLUSIONS: This observational study in a clinical setting is in line with the benefit of CR for patients with mild AD reported in recent randomized controlled trials. The benefit obtained for adapted activities remained after 1 year, even if global cognition declined. Moreover caregiver's burden related to all individually relevant daily activities (from a list of 98) evaluated within the CR program was decreased after 1 year. Those preliminary results emphasize the importance of choice for the measurement instrument to report CR efficacy and claim for further validation of such tools.

Individual goal-oriented cognitive rehabilitation to improve everyday functioning for people with early-stage dementia: A multicentre randomised controlled trial (the GREAT trial).

OBJECTIVES: To determine whether individual goal-oriented cognitive rehabilitation (CR) improves everyday functioning for people with mild-to-moderate dementia. DESIGN AND METHODS: Parallel group multicentre single-blind randomised controlled trial (RCT) comparing CR added to usual treatment (CR) with usual treatment alone (TAU) for people with an ICD-10 diagnosis of Alzheimer, vascular or mixed dementia, and mild-to-moderate cognitive impairment (Mini-Mental State Examination [MMSE] score ≥ 18), and with a family member willing to contribute. Participants allocated to CR received 10 weekly sessions over 3 months and four maintenance sessions over 6 months. Participants were followed up 3 and 9 months post randomisation by blinded researchers. The primary outcome was self-reported goal attainment at 3 months. Secondary outcomes at 3 and 9 months included informant-reported goal attainment, quality of life, mood, self-efficacy, and cognition and study partner stress and quality of life. RESULTS: We randomised (1:1) 475 people with dementia; 445 (CR = 281) were included in the intention to treat analysis at 3 months and 426 (CR = 208) at 9 months. At 3 months, there were statistically significant large positive effects for participant-rated goal attainment (d = 0.97; 95% CI, 0.75-1.19), corroborated by informant ratings (d = 1.11; 95% CI, 0.89-1.34). These effects were maintained at 9 months for both participant (d = 0.94; 95% CI, 0.71-1.17) and informant (d = 0.96; 95% CI, 0.73-1.2) ratings. The observed gains related to goals directly targeted in the therapy. There were no significant differences in secondary outcomes. CONCLUSIONS: CR enables people with early-stage dementia to improve their everyday functioning in relation to individual goals targeted in the therapy.

Implementation and evaluation of a driving cessation intervention to improve community mobility and wellbeing outcomes for people living with dementia: study protocol of the 'CarFreeMe' for people with dementia program.

BACKGROUND: Giving up driving is a pivotal life event and universal challenge for people living with dementia and their families, and a complex area of clinical practice for health professionals who monitor driving cessation. The best outcomes are for individuals to plan for and eventually cease driving, however with insufficient support programs in place, many avoid the issue until it is reaches a crisis point. This program of research investigates a comprehensive support- and education-based intervention targeted at people living with dementia and their care partners who are managing driving cessation. The primary aim of this research is to determine the effectiveness of the program through a cluster randomized controlled trial. METHODS/DESIGN: The intervention (CarFreeMe) is an intensive program delivered by a trained health professional that addresses practical and emotional needs relevant to driving cessation. The seven module program is person-centred, covering awareness raising, adjustment, and practical support that is individualized according to geographic location and the particular goals and preferences of participants. A cluster randomized controlled trial will evaluate the effectiveness of the program. Evaluation will take place pre-intervention, immediately following, and three months post-intervention. Clusters are randomized to either intervention or usual treatment. Participants within clusters will be recruited via primary and secondary care clinics, community agencies, service providers, local media, social media, support groups, and word of mouth. The primary outcome measure for persons with dementia and their care partners is lifespace, collected via (i) smartphone GPS technology and (ii) self-reported number of episodes away from home (during the past week). Secondary outcomes include safe alternative transport status, wellbeing, depression, anxiety, and self-efficacy, which will be collected from dyads. Caregiving strain will be collected from care partner/family member only. A process evaluation of the intervention will also be undertaken. DISCUSSION: There is an urgent need for therapeutic approaches to supporting people living with dementia and their families to negotiate the complex decision making involved in deciding to change their approach to driving. The driving cessation intervention may fill an important gap in service delivery to people living with dementia who are adjusting to life without driving.

Maintenance of occupational therapy (OT) for dementia: protocol of a multi-center, randomized controlled and pragmatic trial.

BACKGROUND: There is a growing interest in developing tailored non-pharmacological strategies to face patients' needs in dementia. Occupational therapy (OT) may contribute to promote self-empowerment of both patients and caregivers. France has implemented nationwide OT over a short-term period of 3/4 months. The main objective of the MathéoAlz study is to measure the impact of maintaining OT over 4 supplementary months on patients' neuropsychiatric symptoms. METHODS/DESIGN: The MatheoAlz trial (Maintenance of Occupational Therapy in Alzheimer's disease) is a multi-center, pragmatic randomized controlled trial testing maintenance of OT over 4 supplementary months compared to routine OT delivered as recommended. This paper describes the study protocol. MatheoAlz plans to enroll 240 dyads, i.e. dementia patients and caregivers, whose main inclusion criteria are: prescription for routine OT, patients with mild or moderate dementia, living at home, receiving support from an informal caregiver. The study will compare a control group of patients benefiting from 12 to 15 initial sessions of OT over 3/4 months and an intervention group of patients benefiting from these initial sessions plus 8 extra home sessions over 4 supplementary months. The main outcome is the patient's neuropsychiatric symptoms assessed by the Neuropsychiatric Inventory at 8 months. Several clinical outcomes and economic consequences are measured at 4, 8 and 12 months. DISCUSSION: This is the first trial designed to assess the specific impact of the maintaining OT on the patients' neuropsychiatric symptoms burden. The results will inform policymakers on strategies to implement in the near future. TRIAL REGISTRATION: This trial was registered at ClinicalTrials.gov on February 16, 2018, identifier: NCT03435705 .

Review of AAC interventions in persons with dementia.

BACKGROUND: Communication is an important priority in dementia research. Communication strategies and scaffolds, specifically through augmentative and alternative communication (AAC), offer vital compensatory support for persons with dementia in an attempt to maintain the latter's quality of life and well-being through participation with others. To date, no research review has been published that synthesizes the current research of AAC in the field of dementia. AIMS: To provide an overview of current AAC strategies and techniques used for supporting communication in dementia by surveying the literature base in a systematic manner, synthesizing the findings and highlighting trends and gaps. METHODS & PROCEDURES: A multifaceted search strategy included nine electronic database searches, using specific keywords. Application of predefined selection criteria during screening procedures led to the inclusion of 39 studies. Data were extracted and studies synthesized according to communication partners; description of AAC strategies and techniques; outcome measures; and communication outcomes. MAIN CONTRIBUTION: This review shows that the majority of the research to date has focused on supporting the interactions of persons with dementia of the Alzheimer's type (DAT) using non-electronic memory and communication aids. Future research should focus on social participation and person-centred communication to optimize functional communication with AAC. Training programmes targeting dyadic interaction and supporting persons with dementia from diverse ethnic backgrounds are avenues for further research. CONCLUSIONS: Research trends and, more importantly, the gaps highlighted in this research review present speech-language therapists and researchers with a set of current priorities that are necessary for the advancement of the knowledge base.

[Some aspects of rehabilitation of disabled persons of the elderly and senior age at the present stage.]

The article presents the results of the analysis of the needs of elderly and elderly disabled in various types of rehabilitation, including providing them with technical means of rehabilitation, reflects the problems that this group of people have when it comes to resolving issues of medical and social rehabilitation. The importance of an integrated approach in carrying out rehabilitation measures in the study contingent was stressed. Attention is focused on some imperfection of the current regulatory and legal framework in the part concerning the examination in the service of medical and social expertise of the disabled elderly and senile. It is proposed to make appropriate changes that provide for a simplified, in-absent examination of this contingent of persons in the service of medical and social expertise, if it is necessary to make or introduce changes to the current individual rehabilitation program, to habilitate.

[Bio-psycho-social model of energizing care of the elderly and senile age at home.]

Due to the introduction of new medical technologies, there is an increase in the number of people, including the elderly and senile age, who have extended their lives, but who need constant care from medical and social services at home. In the study of age differences of biological needs in home care, it was found that for middle-aged people the greatest difficulties and contribution to the reduction of quality of life brought insufficient nutrition, limited independence in the performance of household manipulations due to joint damage, pain and other biological causes, as well as hypothermia syndrome compared with elderly and senile age. For people of older age groups was characterized by the need to bridge the lack of communication; enhancing the role of the family in the implementation of care; increased confidence in caregivers; increased availability of medicines; and increased availability of religious services. Developed on the basis of identified age-based determinants of quality of life, the original model of the bio-psychosocial activating care for the geriatric contingent of patients at home, the difference from traditional approaches is the use of activating kinesitherapy and cognitive exercises, contributes to the achievement of a higher level of functionality and independence of the geriatric patient, which is accompanied by improving the quality of life.

Targeting Functional Decline in Alzheimer Disease: A Randomized Trial.

BACKGROUND: Alzheimer disease results in progressive functional decline, leading to loss of independence. OBJECTIVE: To determine whether collaborative care plus 2 years of home-based occupational therapy delays functional decline. DESIGN: Randomized, controlled clinical trial. (ClinicalTrials.gov: NCT01314950). SETTING: Urban public health system. PATIENTS: 180 community-dwelling participants with Alzheimer disease and their informal caregivers. INTERVENTION: All participants received collaborative care for dementia. Patients in the intervention group also received in-home occupational therapy delivered in 24 sessions over 2 years. MEASUREMENTS: The primary outcome measure was the Alzheimer's Disease Cooperative Study Group Activities of Daily Living Scale (ADCS ADL); performance-based measures included the Short Physical Performance Battery (SPPB) and Short Portable Sarcopenia Measure (SPSM). RESULTS: At baseline, clinical characteristics did not differ significantly between groups; the mean Mini-Mental State Examination score for both groups was 19 (SD, 7). The intervention group received a median of 18 home visits from the study occupational therapists. In both groups, ADCS ADL scores declined over 24 months. At the primary end point of 24 months, ADCS ADL scores did not differ between groups (mean difference, 2.34 [95% CI, -5.27 to 9.96]). We also could not definitively demonstrate between-group differences in mean SPPB or SPSM values. LIMITATION: The results of this trial are indeterminate and do not rule out potential clinically important effects of the intervention. CONCLUSION: The authors could not definitively demonstrate whether the addition of 2 years of in-home occupational therapy to a collaborative care management model slowed the rate of functional decline among persons with Alzheimer disease. This trial underscores the burden undertaken by caregivers as they provide care for family members with Alzheimer disease and the difficulty in slowing functional decline.

Living well with dementia groups: changes in participant and therapist verbal behaviour.

OBJECTIVES: This paper reports two related analyses of verbal material from seven Living Well with Dementia groups: the first examines changes in the verbal behaviours of participants across the course of the sessions in all seven groups; while the second contrasts therapist behaviour in two groups. METHODS: In the first analysis, recordings of three sessions from each group were transcribed and participant descriptions of dementia were analysed using the Markers of Assimilation of Problematic Experiences of Dementia (MAPED) rating procedure. In the second analysis, therapist behaviour in weeks 2 and 8 from two groups (F and G) was analysed using the Hill Counsellor Verbal response rating scale. Inter-rater reliabilities for the two sets of ratings were 'good' and 'very good', respectively. RESULTS: For the MAPED ratings, a five by four contingency table was analysed using chi-squared, which indicated a highly significant change in assimilation. There were significant higher levels of level 1 and 2 markers in the first two sessions and level 4 for sessions 5 and 6. Facilitators used significantly more direct guidance and information giving behaviour in the second session at Location F compared to Location G. CONCLUSIONS: The results suggest that important changes occurred in the way that dementia was described across the seven LivDem groups: this includes both reductions in the avoidance of direct references to dementia after the first two sessions, as well as an increase in 'insight' statements. Directive facilitator behaviour may be associated with poorer outcomes.

The potential of virtual reality-based training to enhance the functional autonomy of Alzheimer's disease patients in cooking activities: A single case study.

Impairments in performing activities of daily living occur early in the course of Alzheimer's disease (AD). There is a great need to develop non-pharmacological therapeutic interventions likely to reduce dependency in everyday activities in AD patients. This study investigated whether it was possible to increase autonomy in these patients in cooking activities using interventions based on errorless learning, vanishing-cue, and virtual reality techniques. We recruited a 79-year-old woman who met NINCDS-ADRDA criteria for probable AD. She was trained in four cooking tasks for four days per task, one hour per day, in virtual and in real conditions. Outcome measures included subjective data concerning the therapeutic intervention and the experience of virtual reality, repeated assessments of training activities, neuropsychological scores, and self-esteem and quality of life measures. The results indicated that our patient could relearn some cooking activities using virtual reality techniques. Transfer to real life was also observed. Improvement of the task performance remained stable over time. This case report supports the value of a non-immersive virtual kitchen to help people with AD to relearn cooking activities.

Can people with Alzheimer's disease improve their day-to-day functioning with a tablet computer?

New technologies, such as tablet computers, present great potential to support the day-to-day living of persons with Alzheimer's disease (AD). However, whether people with AD can learn how to use a tablet properly in daily life remains to be demonstrated. A single case study was conducted with a 65-year-old woman with AD. A specific and structured intervention tailored to her needs was conceptualised for the use of a calendar application on a tablet computer according to the following learning stages: Acquisition, Application and Adaptation. In spite of her severe episodic memory deficit, she showed progressive learning of the tablet application during the intervention phase. Furthermore, data compiled over 12 months post-use show that she used the tablet successfully in her day-to-day life. She was even able to transfer her newly acquired ability to other available applications designed to monitor regular purchases, consult various recipes and play games. Tablet computers thereby offer a promising avenue for cognitive rehabilitation for persons with AD. This success was mainly achieved through a one-on-one individual programme tailored to this person. The limits and constraints of utilising tablet computers for persons with AD are discussed.

Impact of AP@LZ in the daily life of three persons with Alzheimer's disease: long-term use and further exploration of its effectiveness.

AP@LZ is an electronic organiser that was designed to support the day-to-day activities of persons with Alzheimer's disease. To assess the potential of this technology, three participants (NI, JB, RD) were approached to take part in the study. They benefited from a structured cognitive intervention to learn how to operate AP@LZ; the intervention included the following learning stages: Acquisition, Application and Adaptation. Pre- and post-intervention measures were collected. NI, for whom a longitudinal study was conducted, still continued to use AP@LZ 24 months post-intervention. JB and RD also showed a gradual improvement in their performance throughout the intervention phase (sessions 1 to 19 for JB: performance increased from 50 to 100%; sessions 1 to 25 for RD: from 56 to 89%). The results of the use of AP@LZ in activities of daily living suggest that the application was beneficial for three persons with Alzheimer's disease whose profiles differed notably (age, cognitive and social profiles). Thus, results indicate that they were all able to learn how to operate AP@LZ's functions and to use them in their activities of daily living. Cognitive intervention appears to play an important role for the promotion of learning and adoption of such technology.
