Opis:
Introduction. Alzheimer’s disease (AD) is one of the most common neurodegenerative diseases, which is a serious health problem for societies that live longer. Spontaneous dominant mutations and polymorphisms of selected genes play an important role in development of AD. Aim. Several polymorphisms in selected genes strongly associated with development of Alzheimer’s disease were highlighted in this review: APOE, CYP46, APP, PSEN1, PSEN2, UBQLN1, BACE1, PRND, APBB2, TOMM 40. These gene polymorphisms have a significant role in the development of Alzheimer’s disease and they have potential to be biomarkers. Researchers combine efforts to find significant polymorphisms that would ensure that a person is predisposed to the occurrence of disease symptoms. This topic is often taken up by scientists seeking to develop effective genetic tests for diagnosing AD. Material and methods. Analysis of literature from web of knowledge: Web of Science (all database), NCBI and PubMed. Results. We reviewed the selected important genes and polymorphisms which are most often associated with development of AD. Conclusion. It should be noted that nowadays scientists strive not to focus on only one polymorphism in the gene but on several polymorphisms in different genes concomitantly and above all on interactions between them to the diagnosis of this disease. Only this approach to AD will contribute to the creation of appropriate identification methods. Moreover, we should use the new generation tools - the platform for collecting data and personalized medicine.

Opis:
Language functions, particularly disordered lexical skills were diagnosed in the examined woman based on selected diagnostic tests of the Boston Diagnostic Aphasia Examination (BDAE). Furthermore, an experimental version of the author's original test for assessing lexical-semantic performance in dementia was used. The author presents a case study of a 79-year-old woman diagnosed with logopenic variant primary progressive aphasia (lvPPA) secondary to Alzheimer’s disease. The author describes the symptoms of anomie manifested by the study participant and the supplementary strategies she applied in the case of lexical deficits. The analysis of the findings obtained in the course of language function assessment allowed the author to assess the fluency of speech, speech comprehension, repetition and naming. The study participant diagnosed with lvPPA was observed to manifest the following: an absence of motor speech disorders, absence of characteristics of evident agrammatism, preserved comprehension of individual words, preserved semantic knowledge of objects, disordered retrieval of words in spontaneous speech and in attempts to name, and disordered repetition of sentences and phrases. The analysis of the discussed case study allowed the author to discuss the progressive lexical deficits manifested by the lvPPA patient and to record those supplementary strategies that were most frequently applied in the lexical difficulties experienced by the female patient diagnosed with lvPPA.

Opis:
Handwriting is a component of the complex language that came about late in the history of mankind and which develops late in human beings. Numerous works have raised changes in both the graphic and kinematic characteristics of writing. Although, age does not modify the lexical and syntactic parameters of language, it can however modify its spatial structure, especially pressure and speed. Many neurodegenerative pathologies, especially Alzheimer's disease, are characterized by a progressive disorganization of writing. Depending on the cognitive stage of the dementia, the graphic gesture deteriorates as does the spatial construction. Objective: Our study aims at assessing the characteristics of Arabic writing in a healthy Moroccan population and to compare it to people with mild to moderate Alzheimer's disease. Our objective is to help health professionals detect early cognitive deterioration in neurodegenerative diseases by analyzing the graphic gesture. Handwriting is captured on a graphic tablet (WACOM) and is analyzed "online" as a sequence of acquired signals (position, pressure, speed and pen inclination) in Moroccan patients with mild to moderate Alzheimer's disease and these were compared to those of normal volunteers. We performed a first analysis of the results from 18 Alzheimer's patients compared to 18 control subjects. The results reveal differences between the control and Alzheimer's groups. AD subjects had lower speeds and accelerations compared to the control subjects. The time spent on paper and in the air was significantly greater in the AD subjects. This preliminary analysis of the results allowed us to identify distinguishing characteristics through the analysis of different handwriting parameters in order to identify the two groups studied.

Opis:
The current study was undertaken to elucidate a possible neuroprotective role of dehydroepiandrosterone (DHEA) against the development of Alzheimer's disease in experimental rat model. Alzheimer's disease was produced in young female ovariectomized rats by intraperitoneal administration of AlCl3 (4.2 mg/kg body weight) daily for 12 weeks. Half of these animals also received orally DHEA (250 mg/kg body weight, three times weekly) for 18 weeks. Control groups of animals received either DHAE alone, or no DHEA, or were not ovariectomized. After such treatment the animals were analyzed for oxidative stress biomarkers such as hydrogen peroxide, nitric oxide and malondialdehyde, total antioxidant capacity, reduced glutathione, glutathione peroxidase, glutathione reductase, superoxide dismutase and catalase activities, antiapoptotic marker Bcl-2 and brain derived neurotrophic factor. Also brain cholinergic markers (acetylcholinesterase and acetylcholine) were determined. The results revealed significant increase in oxidative stress parameters associated with significant decrease in the antioxidant enzyme activities in Al-intoxicated ovariectomized rats. Significant depletion in brain Bcl-2 and brain-derived neurotrophic factor levels were also detected. Moreover, significant elevations in brain acetylcholinesterase activity accompanied with significant reduction in acetylcholine level were recorded. Significant amelioration in all investigated parameters was detected as a result of treatment of Al-intoxicated ovariectomized rats with DHEA. These results were confirmed by histological examination of brain sections. These results clearly indicate a neuroprotective effect of DHEA against Alzheimer's disease.

Opis:
Alzheimer's disease is of neurodegrading nature and belongs to progressive diseases. It is classified as the most common cause of dementia disease of old age. The incidence is rapidly increasing in the group of patients over 65 years of age. The characteristic symptoms include cognitive and functional disorders. As the disease progresses, and thus the severity of symptoms increases the scope of activities related to patient care grows. The role of nurses is conditioned by the patient's functional status and demand for professional care. The area of activities reflects deficits in carrying out self-service and the lack of caregivers’ knowledge. The nurse should identify patients’ problems and as well as those of their families, define the goals to be reached, implement appropriate measures and evaluate the actions. Patient’s education is a process of successive, logically and causally related steps that are being taken in order to induce changes in the behavior of the patient. In connection with the progression of the disease and, consequently, total reliance, it requires from nurses appropriate attitude adequate to the work performed and characterised by outstanding high morality. The educational role in the case of patients with AD and their families plays a significant role in the process of treatment. It provides a sense of security and psychological support. The patient at every stage of the disease is guaranteed to have adequate quality of life. Also, it prepares the family to the care of the patient at home and defines various ways to solve problems.
Choroba Alzheimera ma charakter neurodegradacyjny i należy do chorób postępujących. Zaliczana jest jako najczęstsza przyczyna choroby otępiennej wieku podeszłego. Częstość występowania gwałtownie wzrasta w grupie ludzi powyżej 65 roku życia. Charakterystycznymi objawami są zaburzenia funkcji poznawczych oraz funkcjonalnych. Wraz z postępem choroby, a tym samym nasileniem objawów zwiększa się zakres działań opiekuńczo-pielęgnacyjnych wobec pacjenta. Rola pielęgniarki uwarunkowana jest stanem funkcjonalnym pacjenta oraz zapotrzebowaniem na profesjonalną opiekę. Obszar działań odzwierciedla deficyty w wykonywaniu czynności samoobsługowych oraz brak wiedzy opiekunów. Pielęgniarka powinna określić problemy pacjenta i jego rodziny, postawić cele do wykonania, wdrożyć odpowiednie środki realizacji oraz ocenić działania. Edukacja pacjenta to proces kolejno następujących, powiązanych logicznie i przyczynowo czynności, które są podejmowane w celu wywołania zmian w zachowaniu pacjenta. W związku z progresją choroby i w konsekwencji całkowitej niesamodzielności, wymaga od pielęgniarki odpowiedniej postawy adekwatnej do wykonywanej pracy oraz wyróżniającej się dużą moralnością. Rola edukacyjna w przypadku pacjentów z AD oraz ich rodzin odgrywa znaczącą rolę w procesie leczenia. Zapewnia poczucie bezpieczeństwa oraz wsparcia psychicznego. Pacjent na każdym etapie choroby ma zapewnianą odpowiednią jakość życia. Poza tym przygotowuje rodzinę do opieki nad pacjentem w warunkach domowych oraz wskazuję różne drogi rozwiązania problemów.

Opis:
Molecular cloning and sequencing of a cDNA encoding rabbit presenilin-1 (Ps1) fragment was performed by reverse transcription polymerase chain reaction (RT-PCR) using primers: 5'-GGA TGA GCA GCT AAT CTA TAC C-3' and 5'-TCC ATT CAG GGA GGT ACT TGA TA-3'. The cDNA fragment revealed 402 nucleotides. The sequence was well conserved and found to be 91, 90, 88, 87 and 78% homologous to that of human, lemur, rat, mouse and chicken, respectively. The cDNA translated into a 130 amino-acid protein fragment. The deduced amino-acid sequence was also well conserved in various species and exhibited 98% similarities with those of rat, lemur and human homologues. However, differences were noticed at residues 145, 168 and 212. This cDNA fragment is quite significant because it is the most conserved portion of Ps1 in various animals and encodes four transmembrane regions (TM2, 3, 4, 5) as defined in human Ps1. Moreover, it includes more than 50% of the sites at which substitutions have been reported in familial Alzheimer's disease (FAD). Therefore, it is suggested that the rabbit can be used as an experimental model for future studies on Ps1 and its physiological functions to work out possible pathways leading to FAD linked neurodegeneration.

RESEARCH OBJECTIVE: The aim of this paper is to summarize the knowledge of non-pharmacological treatment in the care of people with Alzheimer’s disease. The contribution is theoretical and provides a suitable prerequisite for further examination of the subject matter, namely the need for quality education and the need to change the approach of care for people with Alzheimer’s disease. THE RESEARCH PROBLEM AND METHODS: The presented contribution approaches the preferred values of care such as coping, self-decision and identity from the clients perspective, as well as new trends in non-pharmacological treatment of Alzheimer’s. Based on the study of professional domestic and foreign literature of social, psychological and medical orientation, we approach selected non-pharmacological therapies. THE PROCESS OF ARGUMENTATION: After defining the goal of the contribution and the basic concepts of Alzheimer-type dementia, it follows (i) the theory of physical environment adaptation, (ii) Tom Kitwood’s approach to care and (iii) health promoting and preventive approach in the social-healthcare sector. A substantial part of the argumentation is the need to create a new culture of care provision. RESEARCH RESULTS: The result of this argumentation is the need for quality preparation of future generations of healthcare professionals and the need for a change in the philosophy and culture of providing care for people with dementia in the countries of Eastern and Central Europe. CONCLUSIONS, INNOVATIONS AND RECOMMENDATIONS: This analysis confirms the need to change the attitudes and self-reflection of helping professionals in the care of people with Alzheimer’s disease. There is also an urgent need to change the preparation of future generations of assisting professionals and further education in line with the latest research and knowledge on the provision of social and health care.

Opis:
Introduction. Alzheimer disease (AD) is one of the best-known diseases. It is neurodegenerative disease characterized by gradual memory loss and dysfunction of behaviour. The pathogenesis of this disease is unclear. Icariin (ICA) is a flavonoid found in a Chinese medicinal herb. It is recognised for a wide range of biological and medical activities: anti-tumour and anti-inflammatory, and also has an impact on the nervous system: stimulates neuroproliferation and prevents neuron’s apoptosis. ICA may have a potential role in AD disease treatment. Objective. The purpose of this article is to review current knowledge about mechanisms and use of ICA in AD treatment. State of knowledge. AD does not present established pathomechanism, about which there are some hypotheses. Each hypothesis mentioned and checked in this review, with result that ICA may have a potential role. One well-known hypothesis is that about amylolytic which is associated with amyloid precursor protein (APP) gene mutation, which leads to amyloid beta (Aβ) protein accumulation and to occurenc of the disease. In this hypothesis, ICA may inhibit Aβ protein aggregation or alter APP expression. ICA may stifle neuronal apoptosis and promote neurogenesis and neuromodulation. According to other hypotheses, ICA could also impact on iron overload in the brain, harmful for neurons hyperhomocysteinaemia, disorder of the intracellular calcium management. Modification of theTau protein structure is another one theory of ICA action. Flavonoid from China may also have an influence on axonal transport. Conclusions. According to the literature there is no single mechanism of ICA action in slowing down AD progress. A wide range of therapeutic points is demonstrated by the broad effect of this substance. Further research is mandatory.

Opis:
Alzheimer’s disease is the most common form of dementia that can cause a brain neurological disorder with progressive memory loss as a result of brain cell damage. Prevention and treatment of disease is a key challenge in today’s aging society. Accurate diagnosis of Alzheimer’s disease plays an important role in patient management, especially in the early stages of the disease, because awareness of risk allows patients to undergo preventive measures even before irreversible brain damage occurs. Over the years, techniques such as statistical modeling or machine learning algorithms have been used to improve understanding of this condition. The objective of the work is the study of the methods of detection and progression of Alzheimer’s disease through artificial intelligence techniques that have been proposed in the last three years. The methodology used was based on the search, selection, review, and analysis of the state of the art and the most current articles published on the subject. The most representative works were analyzed, which allowed proposing a taxonomic classification of the studied methods and on this basis a possible solution strategy was proposed within the framework of the project developed by the Cuban Center for Neurosciences based on the conditions more convenient in terms of cost and effectiveness and the most current trends based on the use of artificial intelligence techniques.
