Insights and recommendations for working collaboratively and improving care in Alzheimer's disease: Learnings from the Finding Alzheimer's Solutions Together (F.A.S.T.) Council.

BACKGROUND: Collaborations between patient organisations (POs) and the pharmaceutical industry can help identify and address the unmet needs of people living with a disease. In Alzheimer's disease (AD), the scale and complexity of the current unmet needs call for a broad and cross-sectoral collaboration, including people living with Alzheimer's (PLWA), their care partners and the wider research community. OBJECTIVE: This study aimed to describe learnings from the Finding Alzheimer's Solutions Together (F.A.S.T.) Council, a collaboration between POs and Roche, convened to better understand the unmet needs of PLWA and their care partners. RESULTS: 1. Learnings from the collaboration, including clarifying objectives and members' expectations upfront, and establishing a set of guiding values and engagement principles. 2. Insights and recommendations for improving care in AD, including a wide range of unmet needs and potential solutions, systematically captured throughout the PLWA journey. These have resulted in several published reports and other outcomes, including (1) 'Portraits of care', highlighting the role of care partners, and the impact of coronavirus disease 2019 on care; (2) Clinical trial guidebook, recommending how PLWA and care partner experience can be incorporated into trial design; (3) 'Commitments Catalogue', highlighting progress by governmental organisations in achieving their commitments; and (4) a report to guide policy on improving diversity, equity and inclusion in clinical trials. CONCLUSIONS: Close collaboration between POs and the pharmaceutical industry in AD can enable effective research, in which PLWA and care partners are engaged as 'experts through experience' to help identify key unmet needs and co-create solutions with the wider AD research community. This paper and the work undertaken by the F.A.S.T. Council may act as a blueprint for meaningful collaboration between POs and the pharmaceutical industry. PATIENT OR PUBLIC CONTRIBUTION: The paper reports the collaboration between POs, the F.A.S.T. Council and Roche to progress towards a future in which PLWA can live fulfilling lives with their disease managed well. CLINICAL TRIAL REGISTRATION: Not applicable.

Discriminant Potential of the Alzheimer's Disease Assessment Scale-Cognitive Subscale (ADAS-Cog) in Greek Older Adults with Subjective Cognitive Decline and Mild Cognitive Impairment.

Background: Alzheimer's Disease Assessment Scale Cognitive Subscale (ADAS-Cog) is a widely used screening tool for detecting older adults with Alzheimer's disease among their cognitively healthy peers. A previous study in Greek population showed that ADAS-Cog-Greek (G) is a valid tool and can identify people with Alzheimer's disease from older adult control group; however, there is no current data about whether ADAS-Cog can differentiate older adults with mild cognitive impairment (MCI) from those who have subjective cognitive decline (SCD). Objective: The current study aimed to examine the discriminant potential of ADAS-Cog-G in Greek older adults who meet the criteria for SCD or MCI. Methods: Four hundred eighty-two community-dwelling older adults, visitors of the Greek Alzheimer Association and Related Disorders, were enrolled in the current study. One hundred seventy-six of them met the criteria for SCD and three hundred six had MCI. Results: Path analysis applied to the data showed that age, as well as educational level affected ADAS-Cog-G performance. Results showed that the cut-off scores, which better discriminate people with SCD from MCI as well as their sensitivity and specificity values, were extracted in participants with high educational level (13 educational years<) and mainly under the age of 75 years. Conclusions: The current study provided evidence concerning the discriminant potential of ADAS-Cog-G to differentiate older adults with SCD from those with MCI in the Greek population, and therefore contributes to the relevant literature on the field.

Cognition and Functionality Were Not Affected Due to the COVID-19 Pandemic in People with Mild Cognitive Impairment and AD Dementia Attending Digital Non-Pharmacologic Interventions.

BACKGROUND: The majority of previous studies showed that older adults with mild cognitive impairment (MCI) as well as Alzheimer's disease dementia (ADD) had impaired cognition and mood status, as well as increased behavioral disturbances after the first wave of the COVID-19 pandemic. However, there are still controversial data as regards the multifactorial impact of the restrictive measures on cognition, mood and daily function in older adults with MCI and ADD. AIM: In the current study, the scope is to identify possible deterioration by means of cognitive and functional level due to mood and behavioral alterations during the second quarantine imposed in Greece between November 2020 and May 2021, as well as one year after the second quarantine, in May 2022. METHODS: Participants were recruited from the two day centers of the Greek Association of Alzheimer Disease and Related Disorders (GAADRD). They underwent three yearly follow up assessments from May 2020 to May 2022 and participated in cognitive training interventions (through digital online means) during the aforementioned period. Mixed measures analyses of variance as well as path models were used for the study's purposes. RESULTS: The study sample comprised 210 participants (175 people with MCI and 35 people with ADD). The mean age was 71.59 and 77.94 for people with MCI and mild ADD, respectively, whereas the average number of years of education was 12.65 for those with MCI and 9.83 for people with mild ADD. The results show that participants' deterioration rate (D), calculated by means of their performance in neuropsychological and functional assessments between 2020 and 2021 (D1) and 2021 and 2022 (D2), did not change significantly, except for the Rey Auditory Verbal Learning Test (RAVLT), since both groups displayed a larger D2 across the test conditions (immediate recall, fifth trial and delayed recall). Trail Making Test-B (TMT-B) performance, applied only in the MCI group, decreased more in relation to the deterioration rate D2. Additionally, two path models were applied to measure the direct relationships between diagnosis, performance in tests measuring mood and neuropsychiatric disturbances (NPI) and cognition, as measured by the RAVLT, in the 2020-2022 assessments. TMT-B was administered only in the MCI population, and therefore was not included in path models. The results show that participants' scores in RAVLT conditions were related to diagnosis and NPI performance, which was positively affected by diagnosis. No other relationships between RAVLT with mood tests were observed. CONCLUSIONS: Our results show that after the second lockdown period, the neuropsychological performance of people with MCI and ADD, calculated by means of their D2, did not change, except from their verbal memory, as well as visual scanning and information processing, measured using the TMT-B. Therefore, it can be assumed that those who were enrolled in digital non-pharmacological interventions during the COVID-19 pandemic home restrictions did not experience increased cognitive and functional deterioration due to mood and behavioral alterations after the pandemic.

The Dementia Knowledge Assessment Scale, the Knowledge in Dementia Scale, and the Dementia Knowledge Assessment Tool 2: Which Is the Best Tool to Measure Dementia Knowledge in Greece?

Background: Measuring dementia knowledge can be a valuable tool for assessing the effectiveness of dementia awareness activities, identifying the potential benefits of dementia training programs, and breaking down common myths and stereotypes about dementia. Objective: To compare the psychometric properties of three widely used dementia knowledge tools, the Dementia Knowledge Assessment Tool 2 (DKAT2-G), the Dementia Knowledge Assessment Scale (DKAS-G), and the Knowledge in Dementia Scale (KIDE-G) in the Greek adult population. Methods: A convenience sample of 252 participants from the general population completed the survey online. Statistical analyses included Cronbach's internal reliability, retest reliability, factor analysis, concurrent and construct validity, and floor and ceiling effects. Results: The DKAS-G had the most appropriate reliability levels (Cronbach's alpha  =  0.845; retest reliability  =  0.921), whereas the DKAT2-G had satisfactory indexes (Cronbach's α= 0.760; retest reliability  =  0.630). The KIDE-G showed unsatisfactory reliability (Cronbach's α= 0.419; retest reliability  =  0.619). Construct validity was confirmed for all questionnaires, showing that all of them detected participants with pre-existing knowledge of dementia. Confirmatory factor analysis revealed a four-factor model for the DKAS-G and proposed the removal of 5 items. Floor and ceiling effects were found for the DKAT2-G and the KIDE-G, mainly among those who had previously participated in dementia training. Conclusions: The DKAS-G was found to have the highest levels of reliability and validity. The results prove that the DKAS-G meets the requirements for measuring dementia knowledge and evaluating dementia training programs in health professionals, caregivers, and the general population.

Examining Voting Capacity in Older Adults with and without Cognitive Decline.

BACKGROUND: Nowadays, controversy exists regarding the stage of cognitive decline and/or dementia where voting capacity is diminished. AIM: To evaluate whether general cognitive status in advancing age predicts voting capacity in its specific aspects. METHODS: The study sample comprised 391 people: 88 cognitively healthy older adults (CH), 150 people with Mild Cognitive Impairment (MCI), and 153 people with Alzheimer's disease dementia (ADD). The assessment included CAT-V for the voting capacity and Mini Mental State Examination (MMSE) for general cognitive ability. ANOVAs and ROC curves were the tools of statistical analysis towards (a) indicating under which MMSE rate participants are incapable of voting and (b) whether the CAT-V total score can discriminate people with dementia (PwADD) from people without dementia (PwtD). RESULTS: Out of the six CAT-V questions, one question was associated with a low MMSE cutoff score (19.50), having excellent sensitivity (92.5%) and specificity (77.20%), whilst the other five questions presented a higher MMSE cutoff score, with a good sensitivity (78.4% to 87.6%) and specificity (75.3% to 81.7%), indicating that voting difficulties are associated with cognitive status. Secondarily, the total CAT-V score discriminates PwADD from PwtD of 51-65 years (sensitivity 93.2%/specificity 100%-excellent), PwADD from PwtD of 66-75 years (sensitivity 73.3%/specificity 97.1%-good), PwADD from PwtD of 76-85 years (sensitivity 92.2%/specificity 64.7%-good), whilst for 86-95 years, a cutoff of 9.5 resulted in perfect sensitivity and specificity (100%). CONCLUSION: According to MMSE, PwADD have no full voting competence, whilst PwtD seem to have intact voting capacity. The calculated cut-off scores indicate that only people who score more than 28 points on the MMSE have voting capacity.

Emotional Function, Negative Thoughts about the Pandemic, and Adaptability Skills among Dementia Caregivers during the COVID-19 Pandemic.

Background: It can be easily inferred that dementia caregivers were severely affected by the general home confinement, or 'lockdown', due to their caregiving roles. Aim: The aim of the current study is to investigate how the quarantine measures applied during the COVID-19 pandemic affected the emotional function (specifically the emotional management, emotional experience, and stress symptoms) and the negative thoughts, as well as the adaptability skills, of Greek dementia caregivers. Materials andMethods: In total, 303 participants (138 in the non-caregiving adults-control group; 165 in the dementia caregivers-experimental group) were recruited from the day centers of the Greek Association of Alzheimer Disease and Related Disorders (GAADRD) from June 2020 to January 2021 in Thessaloniki, Greece. The caregiving population was split into group 1 (those who participated in support groups) and group 2 (those who did not participate in support groups). A self-reported questionnaire was created for research purposes and was digitally administered to participants via Google forms. Results: During the quarantine period, dementia caregivers had more difficulties in emotional management, especially in regards to stress symptoms, which was measured via the Beck Anxiety Inventory (BAI), in comparison to the control group. In regards to the caregiving populations, caregivers from group 1 were more able to manage their emotions according to their self-reports, but had increased agony and loneliness. Moreover, statistical significance was found between emotional management, negative feelings, and stress symptoms in those from group 2 who self-reported that the PwD deteriorated. This evidence was not found in group 1. Finally, there were no differences in the means of negative thoughts about the pandemic, as well as in the adaptation skills, both in dementia caregivers and in the control group, according to their self-reports. Discussion: It seems that different emotional aspects were affected in the dementia caregivers' population, and, therefore, future psychotherapeutic interventions should focus on those most severely affected by the restrictive measures imposed.

The discriminant validity of Rey Complex Figure Test (RCFT) in subjective cognitive decline, mild cognitive impairment (multiple domain) and Alzheimer's disease dementia (ADD; mild stage) in Greek older adults.

Aim: The goal of this study was to determine the discriminant potential of the Rey Complex Figure Test (RCFT) in older adults with Mild Cognitive Impairment multiple domain (mdMCI) and Alzheimer's Disease Dementia (ADD; mild subtype) as compared to older adults with Subjective Cognitive Decline (SCD).Materials and methods: We administered RCFT in 608 older adults, dividing them in three groups (217 individuals with SCD; 304 mdMCI population; 106 people with mild ADD, aged 50-90 years; M = 66.9, SD = 8.4) and a mean education of 10.20 (SD 4.3) years.Results: RCFT subtests have excellent discriminant validity, mainly between people with SCD and those with mild ADD. However, its discriminant validity in detecting older adults with SCD among mdMCI population is still questionable.Discussion: The use of RFCT in discriminating older adults with SCD from those with mild ADD both in research as well as in clinical practice is highly recommended.

Greek Adaptation of the Positive Aspects of Caregiving (PAC) Scale in Dementia Caregivers.

Objectives: The aim of the present study is to validate the Positive Aspects of Caregiving (PAC) scale in Greek informal family caregivers of patients with dementia, in order to assess its psychometric properties.Methods: Two hundred and forty-seven dementia caregivers completed the Greek version of the PAC (G-PAC) scale in correlation with the following psychometric tools, the Beck Depression Scale, the Zarit Burden Interview (ZBI), the Beck Anxiety Inventory (BAI), the Quality of Life-AD (QoL-AD), the Perceived Stress Scale (PSS), and the Neuropsychiatric Inventory (NPI). Caregivers were included in the study after they had been initially informed of its purpose and completed the informed consent.Results: The Principal Component Analysis (PCA) extracted two factors for the G-PAC, which is also in agreement with the original version, which is Enriching Life and Affirming Self. Concurrent validity suggested significant correlations between G-PAC and behavioral and psychological symptoms of dementia and with perceived stress. In regard to the reliability measures, the results showed that the G-PAC scale has very good internal reliability and high levels of test-retest reliability.Conclusions: The scale is a both valid and reliable tool, and therefore it can be used to assess the positive aspects of caregiving in dementia caregivers.Clinical implications: The development of positive psychology measures in dementia care can be regarded as the cornerstone of the psychotherapeutic interventions addressed to caregivers, and therefore helping them to adapt better in their caregiving role.

Rey Complex Figure Test (RCFT): Norms for the Greek older adult population.

BACKGROUND: The Rey Complex Figure Test (RCFT) is an integral part of every neuropsychological assessment, measuring visuoconstructional abilities in research and clinical practice. AIMS: Our goal was to create norms for the Greek older adults over 50 years old since there is no previous relevant study in Greece. METHODS: The RCFT was administered to 228 cognitively intact individuals aged 50 to 87 years (M = 64.12, SD = 8.69) with education from 3 to 23 years (M = 11.5, SD = 4.45). First, regression analyses explored the impact of demographics on RCFT performance. Afterwards, we calculated normative data using raw scores and transformed to percentile scores for RCFT Copy, Immediate recall, Delayed Recall, and Recognition tasks. RESULTS: Age and education were predictors of the Copy and Recall trials, whereas gender was not, having as the only exception the Recognition condition. Greek normative data adjusted for age and education level for the three RCFT conditions and gender for the Recognition trial are presented, as well as the relationship between the RCFT sub tasks. DISCUSSION: This is the first study measuring the RCFT norms in cognitively intact Greek older adults. CONCLUSIONS: Future studies should measure the psychometric properties of RCFT in this population.

Cross-Cultural Adaptation and Validation of the Greek Version of the "Full Outline of Unresponsiveness Score": A Prospective Observational Clinimetric Study in Neurosurgical Patients.

BACKGROUND: The Full Outline of Unresponsiveness (FOUR) score is a clinical instrument for the assessment of consciousness which is gradually gaining ground in clinical practice, as it incorporates more complete neurological information than the Glasgow Coma Scale (GCS). The main objectives of the current study were the following: (1) translate and cross-culturally adapt the FOUR score into Greek; (2) evaluate its clinimetric properties, including interrater reliability, internal consistency, and construct validity; and (3) evaluate the reliability of assessments among health care professionals with different levels of experience and training. METHODS: The FOUR score was initially translated into Greek. Next, patients with neurosurgical pathologies in need of consciousness monitoring were independently assessed with the GCS and FOUR score within one hour by four raters who had different levels of experience and training (two board-certified neurosurgeons, a neurosurgery resident, and a registered nurse). Interrater reliability, internal consistency, and construct validity were evaluated for the scales using weighted Cohen's κ (κw) and intraclass correlation coefficients (ICC), Cronbach's α and Spearman's ρ values, respectively. RESULTS: A total of 408 assessments were performed for 99 patients. The interrater reliability was excellent for both the FOUR score (ICC = 0.941) and GCS (ICC = 0.936). The values of κw exceeded 0.90 for all pairs, suggesting that the FOUR score can be reliably applied by raters with varying experience. Among the scales' components, FOUR score's brainstem and respiratory items showed the lowest, yet high enough (κw > 0.60), level of agreement. The interrater reliability remained excellent (κw > 0.85, ICC > 0.90) for all diagnosis and age groups, with a trend toward higher FOUR score values in the most severe cases (ICC = 0.813 vs. 0.723). Both the FOUR score and GCS showed high internal consistency (Cronbach's α > 0.70 for all occasions). The FOUR score correlated strongly with GCS (Spearman's ρ > 0.90 for all raters), suggesting high construct validity. CONCLUSIONS: The Greek version of the FOUR score is a valid and reliable tool for the clinical assessment of patients with disorders of consciousness. It can be applied successfully by nurses, residents, and specialized physicians. Therefore, its use by medical practitioners with different levels of experience and training is strongly encouraged.

Comparison of on Site versus Online Psycho Education Groups and Reducing Caregiver Burden.

OBJECTIVES: The purpose of this project was to comparatively assess the benefit from the effects of the online versus onsite psychoeducative interventions on caregivers' emotional burden, including their sense of burden, anxiety, and depression. METHODS: Seventy-one caregivers of Patients with Dementia (PwD) were divided in two groups, the online versus the onsite, and participated in the 4-month psychoeducational group intervention. Psychosocial assessment was performed using Beck Anxiety Inventory, Beck Depression Inventory and Zarit Burden Interview before and after the intervention. RESULTS: No significant differences were found between the online and onsite groups in anxiety (p = .531), depression (p = .577) and sense of burden (p = .623) after the interventions. Both interventions showed significant reductions across emotional variables measured over the course of the treatment study and treatment interventions. CONCLUSIONS: Both online and onsite interventions are effective at improving emotional health as they reduce the level of anxiety, depression, and sense of caregiver burden. CLINICAL IMPLICATIONS: The use of online psychoeducative interventions is indicative for use by clinicians who work with dementia caregivers as compared to the onsite ones. Therefore, they may be assumed as having significant utility in dementia caregivers, especially when being adapted during the recent confinement measures due to the coronavirus disease pandemic (COVID-19).

Longitudinal Cognitive and Physical Training Effectiveness in MCI, Based on the Experience of the Alzheimer's Hellas Day Care Centre.

This study assesses the effectiveness of a multicomponent Longitudinal Cognitive Training (CT) program plus physical exercise (PE) for people with Mild Cognitive Impairment (MCI). 155 people with MCI, completed a 3 years (3Y) CT+PE, whilst 133 were control. Neuropsychological assessment was performed at baseline and 3 years later, whilst CT+PE had additional annual assessments. According to the results, the 3Y CT+PE outperformed control in cognitive abilities (p < 0.002), and Activities of Daily Living (ADL) (p < 0.001), stabilized their functional performances between 1st and 2nd year, but worsened in working and verbal memory between 2nd and 3 rd year (p < 0.002). Control deteriorated in cognitive functions (p < 0.001) and ADL (p < 0.001) after 3 years, whilst 1.33% of the experimental and 13.53% of the control group progressed to dementia (p < 0.001). Longitudinal CT+PE improves cognitive performance and ADL in MCI and delay the progression to dementia.

Autonomic factors do not underlie the elevated self-disgust levels in Parkinson's disease.

INTRODUCTION: Parkinson's disease (PD) is manifested along with non-motor symptoms such as impairments in basic emotion regulation, recognition and expression. Yet, self-conscious emotion (SCEs) such as self-disgust, guilt and shame are under-investigated. Our previous research indicated that Parkinson patients have elevated levels of self-reported and induced self-disgust. However, the cause of that elevation-whether lower level biophysiological factors, or higher level cognitive factors, is unknown. METHODS: To explore the former, we analysed Skin Conductance Response (SCR, measuring sympathetic activity) amplitude and high frequency Heart Rate Variability (HRV, measuring parasympathetic activity) across two emotion induction paradigms, one involving narrations of personal experiences of self-disgust, shame and guilt, and one targeting self-disgust selectively via images of the self. Both paradigms had a neutral condition. RESULTS: Photo paradigm elicited significant changes in physiological responses in patients relative to controls-higher percentages of HRV in the high frequency range but lower SCR amplitudes, with patients to present lower responses compared to controls. In the narration paradigm, only guilt condition elicited significant SCR differences between groups. CONCLUSIONS: Consequently, lower level biophysiological factors are unlikely to cause elevated self-disgust levels in Parkinson's disease, which by implication suggests that higher level cognitive factors may be responsible.

Memory Clinics and Day Care Centers in Thessaloniki, Northern Greece: 30 Years of Clinical Practice and Experience.

Background: This review describes the diagnostic and interventional procedures conducted in two university memory clinics (established network of G. Papanikolaou Hospital: 1988-2017 and AHEPA hospital: 2017-today) and 2 day care centers (established network of DCCs: 2005-today) in North Greece and their contribution in the scientific field of dementia. The aims of this work are (1) to provide a diagnosis and treatment protocol established in the network of memory clinics and DCCs and (2) to present further research conducted in the aforementioned network during the last 30 years of clinical practice. Methods: The guidelines to set a protocol demand a series of actions as follows: (1) set the diagnosis criteria, neuropsychological assessment, laboratory examinations, and examination of neurophysiological, neuroimaging, cerebrospinal fluid, blood, and genetic markers; and (2) apply non-pharmacological interventions according to the needs and specialized psychosocial interventions of the patient to the caregivers of the patient. Results: In addition to the guidelines followed in memory clinics at the 1st and 3rd Department of Neurology and two DCCs, a database of patients, educational programs, and further participation in international research programs, including clinical trials, make our contribution in the dementia field strong. Conclusion: In the current paper, we provide useful guidelines on how major and minor neurocognitive disorders are being treated in Thessaloniki, Greece, describing successful practices which have been adapted in the last 30 years.

Are There Any Cognitive and Behavioral Changes Potentially Related to Quarantine Due to the COVID-19 Pandemic in People with Mild Cognitive Impairment and AD Dementia? A Longitudinal Study.

The aim of the study was to examine potential cognitive, mood (depression and anxiety) and behavioral changes that may be related to the quarantine and the lockdown applied during the COVID-19 pandemic in Greek older adults with mild cognitive impairment (MCI), and AD dementia in mild and moderate stages. METHOD: 407 older adults, diagnosed either with MCI or AD dementia (ADD), were recruited from the Day Centers of the Greek Association of Alzheimer Disease and Related Disorders (GAADRD). Neuropsychological assessment was performed at baseline (at the time of diagnosis) between May and July of 2018, as well as for two consecutive follow-up assessments, identical in period, in 2019 and 2020. The majority of participants had participated in non-pharmacological interventions during 2018 as well as 2019, whereas all of them continued their participation online in 2020. RESULTS: Mixed measures analysis of variance showed that participants' 'deterioration difference-D' by means of their performance difference in neuropsychological assessments between 2018-2019 (D1) and 2019-2020 (D2) did not change, except for the FUCAS, RAVLT, and phonemic fluency tests, since both groups resulted in a larger deterioration difference (D2) in these tests. Additionally, three path models examining the direct relationships between performance in tests measuring mood, as well as everyday functioning and cognitive measures, showed that participants' worsened performance in the 2019 and 2020 assessments was strongly affected by NPI performance, in sharp contrast to the 2018 assessment. DISCUSSION: During the lockdown period, MCI and ADD patients' neuropsychological performance did not change, except from the tests measuring verbal memory, learning, and phonemic fluency, as well as everyday functioning. However, the natural progression of the MCI as well as ADD condition is the main reason for participants' deterioration. Mood performance became increasingly closely related to cognition and everyday functioning. Hence, the role of quarantine and AD progression are discussed as potential factors associated with impairments.

Pilot feasibility study of cognitive training exercises for Egyptian adults: Proof of concept.

OBJECTIVES: Cognitive training exercises (CTE) are promising and effective interventions to enhance cognitive reserve and slowdown cognitive deterioration in people with subjective memory impairment (SCI) and mild cognitive impairment (MCI). In this pilot study, we aimed to assess the feasibility of CTE among Egyptian adults. METHODS: Eighteen participants above 40 years old were recruited. They underwent baseline neuropsychological assessment and functional assessment. However, after receiving a 6 weeks' cognitive training, eight participants (seven with MCI and one was cognitively intact) dropped out from the study. Finally, 10 participants (8 participants with MCI, 1 with SCI and 1 was cognitively intact) completed 12 weeks of CTE and undergone the post-assessment afterward. CTE included visual, verbal, memory, executive function, visuospatial, attention, and psychokinetic exercises through onsite and home-based sessions. RESULTS: For the 10 participants who completed 12 weeks of CTE, the Wilcoxon signed-rank test showed a statistically significant change in the scores of mini-mental state examination (Z = -2.546, p = 0.011), semantic fluency test (Z = -2.913, p = 0.004), subjective memory complaint questionnaire (Z = -2.913, p = 0.004), Consortium to Establish a Registry for Alzheimer's Disease Word List (first trial: Z = -2.641, p = 0.008; Word list recall: Z = -2.825, p = 0.005), construction abilities (immediate: Z = -2.121, p = 0.034; delayed recall: Z = -2.414, p = 0.016), and Digit span test (forward: Z = -2.724, p = 0.006; backward: Z = -2.724, p = 0.006). CONCLUSIONS: The results of this study suggested that CTE are feasible among Egyptian adults, especially those with MCI, and potentially effective in enhancing global cognition and after 12 weeks of training. Future research should shed light on the efficacy of longitudinal CTE implementation in Arab adults' populations.

Measuring Impulsivity in Greek Adults: Psychometric Properties of the Barratt Impulsiveness Scale (BIS-11) and Impulsive Behavior Scale (Short Version of UPPS-P).

INTRODUCTION: The aim of the present study was to validate the Barratt Impulsiveness Scale (BIS-11th version) scale as well as the short version of the Impulsive Behavior Scale (UPPS-P) in a population of Greek young adults. Secondly, we aimed at validating the BIS-11 in older adults. METHODS: 167 (Group 1) university students completed the Greek version of the BIS-11 (BIS-11-G) and the UPPS (UPPS-P-G) scales. Additionally, BIS-11-G was also administered to 167 (Group 2) cognitively intact older adults, to identify whether it could be used to measure impulsivity in an older adult population. RESULTS: Both scales had satisfactory internal reliability and test-retest reliability, as well as convergent validity in the young adult population. In regard to the factor structure, a principal component analysis (PCA) extracted two factors for the BIS-11-G in the young adult population and three factors in older adults, as well as three factors for the short UPPS-P-G in young adults. CONCLUSIONS: The BIS-11-G and the UPPS-P-G scales can be used to measure different aspects of impulsivity in the Greek population of different ages in research and clinical practice.

Discriminant Validity of the WAIS-R Digit Symbol Substitution Test in Subjective Cognitive Decline, Mild Cognitive Impairment (Amnestic Subtype) and Alzheimer's Disease Dementia (ADD) in Greece.

OBJECTIVE: The aim of the current study was to estimate the discriminant potential and validity of the Digit Symbol Substitution Test (DSST) of the WAIS-R in the Greek elderly population meeting criteria for subjective cognitive decline (SCD), mild cognitive impairment (aMCI; amnestic subtype), or Alzheimer's disease dementia (ADD). METHOD: Four hundred eighty-eight community-dwelling older adults, visitors of the Day Center of Alzheimer Hellas, participated in the study. Two hundred forty-three of them met the criteria for ADD, one hundred eighty-two for aMCI and sixty-three for SCD. RESULTS: Path analysis indicated that the DSST score is affected by age group, educational level, and diagnostic category, but is not affected by gender. The ROC curve analysis showed that the DSST sum score could perfectly differentiate SCD from ADD patients, whereas test's discriminant potential between aMCI and dementia ADD's subtype was satisfactory. However, DSST was unable to separate the SCD from the aMCI group. CONCLUSION: It appears that the DSST is unable to separate the SCD from aMCI population. Therefore, the test in question may be insensitive to incipient cognitive decline. On the contrary, the discriminant potential of the DSST as regards SCD and ADD is excellent, while discrimination between aMCI and ADD is good.

Setting Up a Cognitive Training Service for Egyptian Older Adults.

BACKGROUND: With greying of nations, dementia becomes a public health priority. The rising dementia prevalence escalates both health care expenses and burden, placing the entire healthcare system and caregivers under huge stress. Cognition-oriented interventions have been shown to enhance the overall cognitive performance among healthy and cognitively impaired older adults. OBJECTIVE: This article is assumed to be a steppingstone for the introduction and establishment of cognition- oriented interventions in Egypt. In addition, it aims to offer provisional guidance for health care providers in Arab speaking countries in a stepwise approach in order to establish cognition-oriented intervention services and help them to evaluate and monitor their efficacy. METHODS: Aconsortium of Egyptian and Greek specialists developed a protocol for the operations of the Ain Shams Cognitive Training Lab and the provision of cognition-oriented interventions. This protocol is based on a previous successful protocol that has been implemented in Greece for more than 10 years and is co-designed to fit the needs of older adults in Arabic speaking countries. RESULTS: The types of services offered, their objectives, recruitment of participants, delivery of interventions, measurement of outcomes and privacy policy are all outlined in the policy. CONCLUSION: Establishing the appropriate framework in which cognitive training strategies can be adapted and implemented in Arabic population, constitutes an inevitable achievement in healthy ageing and can be also assumed as a dementia prevention strategy. Moreover, setting up the first cognitive laboratory in Egypt older adults, can be a model of good practice across the Arabic countries.

A survey on the training needs of caregivers in five European countries.

AIM: This survey explored caregivers' perceived training needs in 5 European countries (United Kingdom, Greece, Bulgaria, Poland and Italy). BACKGROUND: Training can enhance the professional capacity of caregivers; however, caregivers' training needs within Europe have not been examined recently. METHODS: A survey conducted in 2015 captured data from 550 caregivers using a convenience sampling strategy, through a structured questionnaire and additional open-ended items and by conducting statistical and content analysis. RESULTS: The results indicated basic nursing skills and specialization, as well as training in psychology-related skills like time management, emotion regulation, communication and advanced health care systems as the emerging training needs. There were some country differences in specific training need areas. CONCLUSIONS: It was concluded that training in basic nursing skills and specialization in nursing specific conditions, in advanced health care systems and in psychology-related skills could add to the professional capacity of European caregivers employed in health and social care. IMPLICATIONS FOR NURSING MANAGEMENT: The findings inform about employed caregivers' training needs in Europe, which may contribute in the provision of quality care and organisational efficiency in health and social care.
