We aim to investigate whether a popular hand exercise could be used to improve the action of eating in patients with Alzheimer’s disease (AD). A 6-month intervention was conducted in 60 patients with AD who live in a nursing home. They were divided into hand exercise and control groups. Patients of the control group maintained their daily routine. The improvement of Edinburgh Feeding Evaluation in Dementia scale in hand exercise group was significantly greater than in the control group ( P = .003). Significant differences in time of autonomous eating and time of simulated eating between patients in the hand exercise and control groups ( P < .05) were noted. The improvements in accuracy of eating action and coordination of eating action from baseline were significant in hand exercise group compared to the control group ( P = .020 and .014, respectively). Hand exercise is a safe and effective intervention to improve the feeding and eating of people with AD.

Alexithymia is widely recognized as the inability to identify and express emotions. It is a construct which consists of four cognitive traits such as difficulty in identifying feelings, describing feelings to others, externally oriented thinking, and limited imaginative capacity. Several studies have linked alexithymia to cognitive functioning, observing greater alexithymia scores associated with poorer cognitive abilities. Despite Alzheimer’s disease (AD) being a neurodegenerative pathology characterized by cognitive troubles from the early stages, associated to behavioral and emotional disturbances, very few investigations have studied the alexithymia in AD. These studies have shown that alexithymia scores—assessed with Toronto Alexithymia Scale (TAS)—were greater in AD patients than healthy participants. The objective of the study was to investigate if the alexithymia was present in patients with mild AD. We hypothesized that the AD group would show more alexithymia features than the control group. We evaluated 54 subjects, including 27 patients diagnosed with mild AD and 27 normal healthy controls, using the Shalling Sifneos Psychosomatic Scale (SSPS-R) and a neuropsychological test battery. Using non-parametric statistical analyses—Wilcoxon and Mann–Whitney U tests—we observed that the SSPS-R scores were similar in the AD and control groups. All participants showed SSPS-R scores below to 10 points, which means no-alexithymia. We did not find significant correlations between SSPS-R scores and cognitive variables in both groups (p > 0.22), but we observed a negative association between name abilities and alexithymia, but it does not reach to significance (p = 0.07). However, a significant correlation between SSPS-R score and mood state, assessed using Zerssen Rating Scale, was found in both groups (p = 0.01). Because we did not find a significant difference in the alexithymia assessment between both subject groups, pot hoc analyses were computed for each item of the SSPS-R. We made comparisons of alexithymic responses percentages in each SSPS-R item between AD and control groups, using Fisher’s test. We observed that AD patients produced more alexithymic responses in some items of SSPS-R test than the control group, particularly about difficulties to find the words to describe feelings, as well as difficulties of imagination capacity and externally oriented thinking. The present results do not confirm our hypothesis and they do not support the results of previous studies revealing great alexithymia in AD.

ABSTRACTThe amount of liver polyploidy in a group of patients with Alzheimer's disease (AD) was compared with that of an age-matched control group. There was great variability in the percentage of cells in each ploidy class from one individual to the next in both control and AD subjects. AD patients had a lower percentage of 2N cells, and a higher percentage of 4N cells than the controls. There was no difference in the percentage of 8N or 16N cells in AD, indicating that there was no shift to higher ploidy classes in AD. The most stringent statistical analysis failed to reveal statistically significant differences between the AD and control groups.

Background: Alzheimer’s disease is the most common cause of dementia. Metals such as zinc , copper, iron are likely involved in the neurodegeneration of Alzheimer’s disease . Copper can catalyze a flux of reactive oxygen species that can damage functional and structural macromolecules in brain. Most studies found association of high serum copper level with Alzheimer’s disease but also some studies did not. Methods: Total 48 patients of Alzheimer’s disease who were diagnosed according to NIA-AA ( National institute of Aging – Alzheimer’s Association) recommendation ( revised NINCDS-ADRDA) criteria were taken as study population purposively and 42 age and sex matched control were selected. Fasting serum copper level were done for both groups. Comparison of serum copper level of Alzheimer’s patients with that of the control group were done to see association. Results : A total of 28 male and 20 female with mean age of 66.20 ± 9.42 (mean±SD) years, 22 male and 20 female with mean age of 63.54 ± 9.74 (mean±SD) years constituted as case and control groups, respectively. The mean of serum copper in case and control groups were 0.95 ± 0.37 versus 0.92 ± 0.25 mg/L (P > 0.05). The present study found that serum copper levels are non-significantly higher in patients with AD than control group, however it did not show a significant relationship with severity of dementia. Conclusion: So our suggestion was to perform a study work including total serum copper level , serum ceruloplasmin level and free serum copper level comparing between a large Alzheimer’s Disease patients group and age , sex matched apparently healthy control group to understand the copper dyshomeostasis in Alzheimer’ Disease.

Background: Alzheimer’s disease (AD) which is the most common type of dementia is characterized by mental or cognitive disorders. People suffering with this condition find it inherently difficult to communicate and describe symptoms. As a consequence, both detection and treatment of comorbidities associated with Alzheimer’s disease are substantially impaired. Equally, action protocols in the case of emergencies must be clearly formulated and stated. Methods: We performed a bibliography search followed by an observational and cross-sectional study involving a thorough review of medical records. A group of AD patients was compared with a control group. Each group consisted of 100 people and were all León residents aged ≥65 years. Results: The following comorbidities were found to be associated with AD: cataracts, urinary incontinence, osteoarthritis, hearing loss, osteoporosis, and personality disorders. The most frequent comorbidities in the control group were the following: eye strain, stroke, vertigo, as well as circulatory and respiratory disorders. Comorbidities with a similar incidence in both groups included type 2 diabetes mellitus, glaucoma, depression, obesity, arthritis, and anxiety. We also reviewed emergency procedures employed in the case of an emergency involving an AD patient. Conclusions: Some comorbidities were present in both the AD and control groups, while others were found in the AD group and not in the control group, and vice versa.

Crucial interaction of caveolin-1 (CAV1) with beta- and gamma-secretases, and aberrant expression of the gene encoding this protein in Alzheimer's disease (AD) support a role for CAV1 in the pathophysiology of this disease.We report a novel polymorphic purine complex stretching ~150 bp of genomic DNA at the 1.5 kb upstream region of the human CAV1 gene, alleles and genotypes of which are associated with sporadic late-onset AD. Extra-short alleles were observed in the case group that were absent in the control subjects. Increased homozygosity for haplotypes was also observed at this region in the Alzheimer's cases, for those alleles and allele lengths shared by the case and control groups [(c2=30.75, df=1, p< .000, OR=4.54, CI 95% (2.56-8.3)]. This region contains GGAA and GAAA motifs, the consensus binding sites for the Ets and IRF family transcription factors, respectively, and is highly conserved in distantly-related non-human primates in respect with location and motif sequence. The effect of this complex sequence on the expression of CAV1, and the related mechanisms in the pathophysiology of AD remain to be clarified.

Apoe Gene Polymorphism

To explore the association of apolipoprotein E polymorphism with Alzheimer's disease (AD), so as to provide possible research value for potential targeted therapy. 120 AD patients and 50 healthy volunteers were enrolled to extract fasting blood samples. ApoE gene polymorphism and blood lipids were tested in blood. ApoE gene and genotype frequency between AD group and control group were compared by PCR and sequencing methods. MMSE, CDR, and BPSD were used to determine the intelligence. ApoE genotype was detected by DNA microarray. ɛ4 carrier accounted for 45% in AD group, which was significantly elevated compared with control group (12%) (P < 0.05). TG, TC, and LDL-C levels were increased, while HDL-C was reduced in ɛ4 allele carriers (allP < 0.05). The MMSE scores of ApoEɛ4 genotype carriers in AD group were markedly lower than those of nonApoEɛ4 genotype carriers (P < 0.05) and control (P < 0.01). The proportion of dementia in ApoEɛ4 genotype carriers from AD group was apparently higher than the ɛ4 gene non-carriers (P < 0.05). The ApoEɛ4 gene is an AD risk factor. The changes of genotype and frequency of ApoEɛ4 gene are the main factors leading to abnormal lipid metabolism in AD patients, suggesting that ApoEɛ4 gene detection might be helpful for the early diagnosis and treatment of AD.

Background: Alzheimer’s disease is predicted to increase dramatically in the near future. Alzheimer’s caregiving brings about severe problems for caregivers. Considering the corrosive consequences of Alzheimer’s disease on Alzheimer’s caregivers, finding an effective intervention is necessary. Thus, the present research conducted by the aim of investigating the effectiveness of cognitive-behavioral treatment for Alzheimer’s disease patients and their caregiver’s protocol on burdens of Alzheimer’s disease on caregivers and their sense of coherence (SOC). Methods: This study was a quasi-experimental research with a pretest-posttest control group design. The target population included all mild Alzheimer’s disease patients and their caregivers referred to the neurology ward of the hospitals in Rasht during summer 2018. According to the medical records and results of screening, 40 mild Alzheimer’s disease, patients and their caregivers recruited by convenience sampling method. After sampling, research participants randomly assigned into two experimental (n= 20) and waitlist control (n=20) groups. The Impact of Alzheimer’s Disease on Caregiver Questionnaire and SOC scale were used to measure the burdens of Alzheimer’s disease on caregivers and caregivers’ SOC. The CBTAC provided for the experimental group participants in 25 sessions of 90-minutes. In the end, the data analyze has done by multivariate analysis of covariance (MANCOVA) and using SPSS24 software. Results: The findings indicated that the CBTAC had a significant effect on the burdens and SOC of Alzheimer’s caregivers in the experimental group (P<0.01). In other words, the CBTAC decreases burdens and increase the SOC of Alzheimer’s caregivers significantly (P<0.01). Conclusion: Based on the research results, the CBTAC is an effective intervention in decreasing caregiving burden and the increasing SOC of Alzheimer’s caregivers. Therefore, CBTAC is a multicomponent intervention that can be used to improve the competency and mental health of Alzheimer’s caregivers.

Abstract Aerobic exercise is widely supported as a disease-modifying treatment for Alzheimer’s disease (AD) in animal models; however, its effects on cognition have been mixed in human studies, which may be attributable to inter-individual differences in aerobic fitness and cognitive responses to aerobic exercise. This study evaluated inter-individual differences in aerobic fitness and cognitive responses to 6-month aerobic exercise in participants with AD dementia by secondarily analyzing the FIT-AD Trial data. Aerobic fitness with the shuttle walk test (SWT), 6-minute walk test (6MWT), and maximal oxygen consumption (VO2max) from cycle-ergometer exercise test, and cognition with the AD Assessment Scale–Cognition (ADAS-Cog). Inter-individual differences were calculated as the differences in the standard deviation of 6-month change (SDR) in outcomes between the intervention and control groups. The sample size was 78 (77.4±6.3 years old, 15.7±2.8 years of education, 41% women). VO2max was available in 26 participants (77.7±7.1 years old, 14.8±2.6 years of education, 35% women). The results show that the SDR was 37.0, 121.1, 1.7, and 2.3 for SWT, 6MWT, VO2max, and ADAS-Cog, respectively, but there were no statistically significant differences between the intervention and control groups in these measures over six months. Our results indicate that inter-individual differences exist in aerobic fitness and cognitive responses to aerobic exercise in AD, which contributed to the favorable, but not statistically significant between-group differences in aerobic fitness and cognition. To conclude, our study is the first to demonstrate inter-individual differences in the responses to aerobic exercise in AD dementia using SDR.

Multiple EBV-transformed B cell lines were established from five patients with a clinical diagnosis of Alzheimer's disease (AD) and six age-matched controls. The supernatants were screened for antibody activity against SDS-treated isolated neurofibrillary tangles (NFT). Reactive supernatants were identified from both the AD and control group. The frequencies of anti-NFT antibody-secreting lines were 6.3 and 1.6% for the AD and the control groups, respectively. A proportion of these supernatants also stained NFT in situ and neurons and/or glia in sections of the frontal and the temporal cortexes of autopsied AD and normal brains, as well as cells from three cell lines (HeLa, fibroblast, and neuroblastoma). Several patterns of staining were revealed by these supernatants, indicating different reactive antigens. One supernatant stained NFT and astrocytes in sections from AD brains. It did not stain sections from two normal brains. This cell line is the result of the immortalization of a circulating B cell making antibody specific for an antigen in AD. The present approach may provide new insights in the pathogenesis of AD.
