Abstract
Background/Purpose: Older patients living with dementia and their caregivers are ideal beneficiaries of telemedicine, cost-effectiveness, caregiver satisfaction, and physician acceptance. The aim is to study the effect of a telemedicine dementia enabled program on the health outcome of dementia patients and their caregivers, as regard the patient outcome, caregiver stress, and caregiver satisfaction. Methods: Ninety-seven (n = 97) elderly subjects were recruited from the outpatient clinics and inpatient ward of Geriatrics Hospital, Ain Shams University Hospitals. Seventy subjects completed 6 months of follow-up using a telegeriatrics model. Patient outcomes (delirium, behavioral and psychological symptoms of dementia [BPSD], and need for home consultations, emergency room [ER] visits, clinic visits, and hospital admissions) were assessed and followed. Caregiver stress was evaluated and monitored using the abridged Arabic version of the Zarit Burden Interview ZBI-A. Caregiver satisfaction was assessed using dedicated satisfaction questionnaire designed by Ain Shams Virtual Hospital. Results: elirium episodes, BPSD episodes, and the need for home consultations, clinic visits, ER visits, and hospital admissions. This was statistically significant after the second, fourth, and sixth months of follow-up (p-value <0.001). In addition, the telegeriatrics follow-up model had a positive effect on both caregiver stress and caregiver satisfaction. Conclusions: The telegeriatrics follow-up model is a useful tool in the improvement of health outcomes of dementia patients, reduction of caregiver stress, and achievement of caregiver satisfaction.

Abstract
BACKGROUND Cognitive decline is one of the aging health problems that strongly affects daily functioning and quality of life of older adults and threatens their independence. The aim of this study was to assess the prevalence and pattern of cognitive impairment (CI) among community-dwelling elderly in Egypt and the contribution of socioeconomic status to inequality in cognitive impairment. METHODS A cross-sectional study involved 470 community-dwelling elderly aged 60 years or older living in Kafr El-Sheikh Governorate, Egypt. Subjects were recruited from home visits, geriatric clubs, and outpatient clinics. The Montreal Cognitive Assessment tools (MoCA & MoCA-B) were used to assess the prevalence of cognitive impairment, Hachinski ischemic score (HIS) to investigate the type of cognitive impairment, Ain Shams Cognitive Assessment (ASCA) tool to assess the pattern of specific cognitive domain affection, and an Egyptian socioeconomic status (SES) scale to classify the SES of the study participants. RESULTS The prevalence of cognitive impairment was 50.2% distributed as 37.7% for mild cognitive impairment (MCI) and 12.5% for dementia. The most common type of cognitive impairment was the degenerative type (47.9%). Pattern of specific domain affection among cognitively impaired subjects ranged from 94% for visuospatial function to 12.7% for abstraction. Cognitive impairment was significantly higher with increasing age, female sex, marital status (single or widow), low education, higher number of comorbidities, and positive family history of cognitive impairment (p < 0.001). Also, cognitive impairment was concentrated mainly among participants with low socioeconomic score (p < 0.001). CONCLUSION In Egypt, cognitive impairment is significantly prevalent and concentrated among those who are in low socioeconomic status. Patients with mild CI were more than those with dementia, and the most common type of CI was the degenerative type. Increasing educational level of low SES population and improving their access to healthcare services are highly recommended to improve the inequity of cognitive impairment.

Abstract
BACKGROUND Alzheimer's disease is a chronic neurodegenerative disorder that results in total cognitive impairment and functional decline. Family members are the most usual caregivers worldwide, resulting in an increasing total burden and a subsequent degradation of their quality of life. OBJECTIVES To evaluate the burden of care and quality of life among informal caregivers to Alzheimer patients in Egypt. METHODS A descriptive research design was used. The study was conducted at outpatient clinics of El-Abbasya Mental Hospital in Cairo, Egypt. This study included 550 informal caregivers of Alzheimer patients. Data were gathered through questionnaires using the Sociodemographic Profile of Family Caregivers, an adopted version of the Montgomery Borgatta Caregiver Burden scale, and Health-Related Quality of Life Scale. RESULTS Nearly three quarters (73.5%) of the informal caregivers were female. Additionally, the physical burden among the informal caregivers was the highest (21.58 ± 8.13), while the psychological burden was the lowest (7.48 ± 25.35). Besides, around one-third (30%) of the informal caregivers had a total poor quality of life. SIGNIFICANCE OF RESULTS Total burden among informal caregivers of Alzheimer patients was relatively high (64.71 ± 26.86). Moreover, less than one-tenth (8%) of the informal caregivers for Alzheimer's patients had a good quality of life, whereas more than half (62%) of them had an average quality of life. In the Egyptian context, ongoing health education initiatives for those who care for Alzheimer patients are essential, and additional research employing large study sample sizes in varied contexts is strongly advised.

Abstract
INTRODUCTION The Addenbrooke's Cognitive Examination III (ACE-III) (2012) is a brief cognitive battery that assesses five sub-domains of cognition (attention and orientation, memory, verbal fluency, language, and visuospatial abilities) which are commonly impaired in dementia. OBJECTIVE We aimed to validate the Egyptian-Arabic ACE-III in dementia patients, and to provide cut-off scores for the ACE-III in diagnosing dementia in Egyptian-Arabic speakers. METHODS We included 37 patients with dementia (Alzheimer's disease, n = 25, vascular dementia, n = 8, and dementia with Lewy bodies, n = 4) and 43 controls. RESULTS There was a statistically significant difference (p < 0.001) in the total ACE-III score between dementia patients (mean 49.81 ± 18.58) and controls (mean 84.84 ± 6.36). There was also a statistically significant difference between dementia patients and controls in all sub-score domains of the ACE-III (p < 0.001). Using a receiver operator characteristic curve, the optimal cut-off score for dementia on the ACE-III total score was 72, (89% sensitivity, 95% specificity, 92% accuracy). CONCLUSIONS The results of this study provide objective validation of the Egyptian-Arabic version of the ACE-III as a screening tool for dementia, with high sensitivity, specificity, and accuracy comparable to other translated versions of the ACE-III.

Abstract
Alzheimer's disease (AD) is a chronic, progressive, multifactorial, and the most common neurodegenerative disease which causes dementia and mental deterioration in the elderly. The available treatments for AD are not disease-modifying drugs and only provide symptomatic relief. Astaxanthin (ATX), a second-generation antioxidant, is a dark red carotenoid and exhibits the highest antioxidant capacity, anti-inflammatory, neuroprotective, and antiapoptotic effects. In this study, we investigated the therapeutic effect of different doses of ATX on the cerebral cortex and hippocampus of AD-like rats. The AD-like model was induced in rats using hydrated aluminum chloride (AlCl3.6H2O) solution that was given orally at a dose of 75 mg/kg daily for 6 weeks. Morris water maze (MWM) behavioral test was performed to confirm the cognitive dysfunction then AD-like rats were orally treated with different doses of ATX (5, 10, and 15 mg/kg) dissolved in dimethyl sulfoxide (DMSO) for six weeks. The results indicated that ATX significantly and dose-dependently improved the performance of AD-like rats treated with ATX during MWM and suppress the accumulation of amyloid β1-42 and malondialdehyde. Also, significantly inhibit acetylcholinesterase and monoamine oxidase activities and the expression of β-site amyloid precursor protein cleaving enzyme 1 (BACE 1). ATX also significantly elevated the content of acetylcholine, serotonin, and nuclear factor erythroid-2-related factor 2 (Nrf2) and miRNA-124 expression. The effect of ATX treatment was confirmed by histopathological observations using H&E stain and morphometric tissue analysis. From this study, we concluded that ATX may be a promising therapeutic agent for AD through targeting different pathogenic pathways.

Abstract
BACKGROUND Dementia is one of the world's greatest public health issues. Most people with dementia receive home care, and family members are vulnerable to feeling burdened and depressed that reinforces the need for caregiver-driven services to mitigate these negative effects. OBJECTIVE The purpose of this research was to evaluate the effect of the psychoeducational program on burden and quality of life of family caregivers for people with dementia. METHODS This randomized controlled trial (RCT) was conducted on 60 family caregivers. Participants were randomly assigned to receive either the 8-session psychoeducational program (study group) or routine care only (control group). The demographic data of the caregivers and their patients, the burden of caregivers using Zarit Burden Interview (ZBI), and the quality of life of the patients using Quality of Life in Alzheimer Disease (QoL-AD) questionnaire were measured before and after the psychoeducational program and compared between the study group and the control group. RESULTS The results revealed that 80% of the family caregivers were female and 42% were daughters. The mean ± SD of the baseline burden was 61 ± 13.7 and 60.9 ± 10 in the study and the control group, respectively. ZBI burden score in the study group demonstrated a significant drop after the psychoeducational program compared to the control group. Logistic regression analysis showed that caregivers who received the psychoeducational program have OR (95% CI) of 14 (3.1-67.8) compared to those who did not receive the psychoeducational program. CONCLUSIONS Psychoeducational program is effective in reducing the family caregivers' perceived burden. These findings need to be considered in developing comprehensive dementia care programs to well increase the strategies that help caregivers to deal with their patients.

Abstract
Abstract
Background
The high illiteracy rates in the North African and Middle Eastern region make direct cognitive testing challenging. Validated instruments for dementia in Arabic language are lacking specially those targeting low-educated subjects.
Objectives
The aim of this study was to develop a cognitive evaluation battery suitable for both educated and illiterate Egyptian elderly people.
Design
A cross-sectional study was conducted. Setting: Ain-Shams University geriatric and ophthalmology wards, geriatrics outpatient clinic, and geriatric clubs. Participants: 159 male and female participants aged ≥ 60 years were recruited.
Measurements
Cut-off points were determined according to DSM-IV criteria for dementia and MMSE scores which divided the participants into 3 quadrants as normal, having mild cognitive impairment and having dementia then application of the new battery test was done.
Results
Test re-test reliability ranged from adequate to high in most of its tests with r ≥ 0.7. There was a statistical significance between all battery tests when divided into normal and dementia according to DSM IV criteria except in digit span forward length, digit span backward length, stimulus cue of confrontation naming and judgment. Means and standard deviations were calculated for each battery subset, for the whole sample, for low-educated group and group with > 9 years education according to three quadrants of MMSE.
Conclusion
A new valid and reliable neurocognitive evaluation battery that can differentiate between normal, mild cognitive impairment, and dementia in both educated and illiterate subjects under the name of Ain Shams Cognitive Assessment (ASCA) scale is now available.

Abstract
Abstract
Background
Mental and neurocognitive disorders are the leading cause of disabilities amongst the older adult populace worldwide. The population of the older adult in Egypt is fast growing. The national census in 2017 revealed a 2.56% increase in the older adult population from the 2006 census, and these figures are expected to double by year 2031. This study aims to review current evidence about the prevalence of mental and neurocognitive disorders amongst older adult population in Egypt.
Results
A systematic review was carried out, and 16 studies met the inclusion criteria outlined in this study. Four main mental and neurocognitive disorders were identified: depression, anxiety, cognitive impairment and dementia. The reported prevalence of depression, anxiety, dementia and cognitive impairment are 23.7–74.5%, 14.2–72%, 3.66–39.2% and 1.74–51.4%, respectively. Anxiety and depression were positively correlated with the female gender, increasing age and lower educational status. Also, cognitive impairment and dementia were positively correlated with age, illiteracy or low education. However, there appears to be inconsistencies in the diagnostic tools used.
Conclusion
Egypt aging population is growing, and this research brings to forefront the scale of mental and neurocognitive disorders amongst the older adult population. This may help ensure evidence-based initiatives are put in place and priority is given to resource allocation for geriatric mental and neurocognitive disorders in Egypt.

Abstract
Alzheimer's disease (AD) is a progressively debilitating neurodegenerative disorder that has no effective remedy, so far, with available therapeutic modalities being only symptomatic and of modest efficacy. Necroptosis is a form of controlled cell death with a recently emerging link to the pathogenesis of several neurodegenerative diseases. This study investigated the role of necroptosis in the pathogenesis of AD and evaluated the potential beneficial effect of the necroptosis inhibitor, necrosulfonamide (NSA), in a rat model of AD. AD was induced by oral administration of AlCl3 (17 mg/kg/day) for 6 consecutive weeks. Administration of NSA (1.65 mg/kg/day) intraperitoneally for 6 weeks significantly amended AlCl3-induced spatial learning and memory deficits, as demonstrated by enhanced rat performance in Morris water and Y-mazes. NSA alleviated the abnormally high hippocampal expression of tumor necrosis factor-alpha (TNF-α), β-site amyloid precursor protein cleaving enzyme 1 (BACE1), β-amyloid, glycogen synthase kinase-3β (GSK-3β), phosphorylated tau protein, and acetylcholinesterase with concordant replenishment of acetylcholine. The amendments of AD perturbations achieved by NSA correlated with its inhibitory effect on the phosphorylation of the key necroptotic executioner, mixed lineage kinase domain-like protein (MLKL). Histopathological alterations supported the biochemical findings. In conclusion, NSA treatment represents a promising anti-Alzheimer's approach, mitigating AD neuropathologies via targeting MLKL-dependent necroptosis.

Abstract
Background In Egypt, the population of older adults is rapidly growing. The last census in 2017 indicated that older adults numbered 94.8 million, which is a 2.56% increase from the 2006 census. There is growing evidence that the older population is at greater risk for some forms of mental disorders such as depression, dementia, and many more. Objective This study aims to review the current evidence regarding the prevalence of mental disorders among older adults in Egypt. This will be achieved by estimating the current prevalence of mental disorders and identifying any sociodemographic correlations with mental disorders. Methods An electronic search of 5 key databases (MEDLINE, PsycINFO, EMBASE, AMED, and PubMed) from their date of inception was conducted. In addition, scans of reference lists and searches of key journals, citations, and relevant internet resources were conducted. Studies were included if they were published in English, point prevalence studies, conducted with older Egyptians aged ≥60 years, and conducted using a validated diagnostic tool to ascertain mental disorders. Studies that did not meet any of these criteria were excluded. Results This systematic review started in November 2018. The literature search of the 5 databases revealed 343 papers. After screening titles and abstracts, scanning citations and reference lists, and searching internet sources, a total of 38 full-text articles were accessed, of which 16 studies met the eligibility criteria and were included. We are currently in the process of data extraction and synthesis. Conclusions This research will help bring the scale of mental disorders among older adults in Egypt to the forefront. This may help ensure evidence-based initiatives are established and that priority is given to resource allocation for geriatric mental health in Egypt.

Abstract
Machine learning algorithms are currently being implemented in an escalating manner to classify and/or predict the onset of some neurodegenerative diseases; including Alzheimer's Disease (AD); this could be attributed to the fact of the abundance of data and powerful computers. The objective of this work was to deliver a robust classification system for AD and Mild Cognitive Impairment (MCI) against healthy controls (HC) in a low-cost network in terms of shallow architecture and processing. In this study, the dataset included was downloaded from the Alzheimer's disease neuroimaging initiative (ADNI). The classification methodology implemented was the convolutional neural network (CNN), where the diffusion maps, and gray-matter (GM) volumes were the input images. The number of scans included was 185, 106, and 115 for HC, MCI and AD respectively. Ten-fold cross-validation scheme was adopted and the stacked mean diffusivity (MD) and GM volume produced an AUC of 0.94 and 0.84, an accuracy of 93.5% and 79.6%, a sensitivity of 92.5% and 62.7%, and a specificity of 93.9% and 89% for AD/HC and MCI/HC classification respectively. This work elucidates the impact of incorporating data from different imaging modalities; i.e. structural Magnetic Resonance Imaging (MRI) and Diffusion Tensor Imaging (DTI), where deep learning was employed for the aim of classification. To the best of our knowledge, this is the first study assessing the impact of having more than one scan per subject and propose the proper maneuver to confirm the robustness of the system. The results were competitive among the existing literature, which paves the way for improving medications that could slow down the progress of the AD or prevent it.

Abstract
Abstract
Background
Although cognitive impairment is common in the elderly population, studies investigating its rate in Hajj pilgrims are lacking.
Objectives
To estimate the rate of cognitive impairment among a sample of Arabic-speaking elderly Hajj pilgrims and examine its association with their activities of daily living (ADL).
Methods
A cross-sectional study was conducted during the Hajj season 1438 Hijri Calendar (August 2017). Hajj pilgrims were recruited using a probability sampling method and were interviewed for demographics, the MINI-Cog and the ADL instrument.
Results
Among the 340 recruited pilgrims, 99 (29.2%) had positive results in the MINI-Cog indicating probable cognitive impairment. In multivariate logistic regression, the educational level (odds ratio (OD) 0.456; 95% CI 0.346 to 0.598) and the need for help during Hajj (OD 0.581; 95% CI 0.342 to 0.984) were found significantly associated with positive MINI-Cog. Although no significant differences in the ADL were found between pilgrims with and without positive MINI-Cog, the scores of the ADL and the MINI-Cog were found to be positively correlated but weak (rs = 0.134, P = 0.013) indicating a possible association between better cognitive functions and better ADL performance.
Conclusion
Probable cognitive impairment among Arabic elderly Hajj pilgrims was found to be very common. Further diagnostic studies and studies on the impact of cognitive impairment on the performance of Hajj pilgrims are warranted.

Epidemiology of Alzheimer's Disease and Dementia in Arab Countries: A Systematic Review. Behav Neurol 2019; 2019:3935943. [PMID: 31772681 PMCID: PMC6854962 DOI: 10.1155/2019/3935943] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2019] [Revised: 05/25/2019] [Accepted: 09/16/2019] [Indexed: 11/17/2022] Open
Abstract
Background/Objectives Contrary to popular belief, the condition of dementia is not an actual discrete disease, but rather a group of symptoms, most notable of which is the disturbance of memory and social ability, often severe enough to impair daily functioning. As a result, it has been a major cause of functional deterioration among varying populations in the world. This study is aimed at reviewing the epidemiology of dementia in Arab countries in terms of its prevalence, distribution, and risk factors. Methods A systematic literature review was conducted using articles published in PubMed, Embase, Scopus, and other local journals between 1990 and 2018. After applying the inclusion and exclusion criteria, a total of 18 studies were concluded to be eligible for the review. Results Prevalence studies demonstrated that dementia is indeed a prevalent condition in Arab countries, ranging between 1.1% and 2.3% among age groups of 50 years and older, as well as between 13.5% and 18.5% among age groups of 80 years and above. However, these results are not different from those of many other countries in the world. Moreover, prevalence was found to vary depending on sociodemographic characteristics. Major risk factors of dementia included hypertension, low income, and low education, while the risk of developing dementia is increased by obesity, diabetes mellitus, and cardiovascular risk factors. Despite the growing evidence regarding the epidemiological distribution and determinants of dementia worldwide, studies from the Arab region remain scarce. Conclusion This systematic review highlights the need for population-based studies to provide necessary information for developing preventive and curative strategies specific to the Arab region.

Abstract
Introduction: Alzheimer’s disease (AD) is a neurodegenerative disorder that has no definite cure. Currently, there is great interest in using plant-based medicines to treat AD. In the present study, the neuroprotective effects of Astragalus kahiricus root extract were evaluated in a retrograde amnesia model. Methods: Male albino mice were given four training sessions in the Morris water maze for seven consecutive days. Treated groups were administered A. kahiricus (25 or 50 mg/kg, i.p.) before ethanol (3.5 gm/kg, i.p) injection. All animals were given a test session in the Morris water maze apparatus. Acetylcholinesterase activity and the levels of oxidative stress biomarkers were also measured. Results: Memory impairment was observed, after ethanol administration, as increased escape latency time and path length travelled by the animals. On the other hand, A. kahiricus significantly reduced both escape latency time and path length. In addition, the extract demonstrated an inhibitory effect on acetylcholinesterase activity and total nitrite level. Moreover, A. kahiricus significantly increased the level of reduced glutathione in mice brain. Conclusion: This study demonstrated the potential behavioural and biochemical neuroprotective properties of A. kahiricus root extract, which might further be considered an important candidate for the treatment of AD.

Abstract
Globally, there is an increase in the older population, whose lives are affected by local cultural norms. In Eastern Mediterranean countries, dementia is conventionally hidden from view with few dedicated services or recognition for diagnosis. The aim of this systematic review is to explore the limited literature on dementia and cognitive impairment among older people in Eastern Mediterranean countries to present an evaluation of current practices and to consolidate knowledge for future planning. Thirty-three studies were identified for inclusion in the review, and four themes were apparent. Firstly, prevalence, comorbidity and gender: In Eastern Mediterranean countries, many studies identify that the prevalence of dementia is high. As is the case elsewhere, many older adults in Eastern Mediterranean countries have at least one coexisting long-term condition, and some experience low life-satisfaction. Secondly, culture: In Eastern Mediterranean countries, the older adult is highly respected, and placement outside of the family home is considered an abandonment of family duty. The term dementia carries stigma, and it is widely believed that dementia is caused by ‘fate’. Thirdly, recognition and tools: There is a lack of verified assessment instruments to assess for dementia. Despite concerns about the cultural appropriateness of the Mini-Mental State Exam, particularly for people who have low literacy levels, and low literacy being the norm in Eastern Mediterranean countries, the Mini-Mental State Examination is the main assessment instrument. Translation and transition of non-Arabic assessment instruments and tools with psychometric properties presents a challenge for clinicians. Finally, workforce issues: health care workers lack knowledge about dementia, as dementia care is a relatively recent addition to the nursing and medical syllabi. While there were some inconsistencies in the papers published, many of the articles call for increasing educational programmes and health and social care policies to promote improved and practical gerontological nursing and medicine. Health care professionals need education about sociocultural, religious, and language needs to deliver improved culturally sensitive care.
