The most common form of dementia in the elderly population is Alzheimer’s disease (AD). World Health Organization (WHO) thus defines Alzheimer’s disease: “a set of neurodegenerative brain symptoms, resulting in progressive impairment of memory, thinking, cognition, counting, language, ability to learn and assessing situations, which disturb everyday life”. It usually develops in 65+-yearolds, and the risk of AD in 85+-year-olds is as high as 50%. It has become a considerable threat to the society, given the longer life expectancy and an increase in the retirement-aged population. AD prevention and treatment methods described in this paper are still being developed and perfected. Studies on genesis of the disease aim at comprehensive understanding of its causes. New, alternative treatment methods are still sough. Researchers develop and test biomarkers that could facilitate early diagnosis.
The article focuses on the analysis of the functioning of the category of the dimension of memory and psychological perception of time by a person suffering from dementia of the Alzheimer type. Our observations were related to the theoretical understanding of psychology researchers memory, psychological perception of time and neuropsychologists. Moving away from a clinical study for the analysis of expression resulting in interaction with investigating, while the participant conversation here is aware of the procedure. This research methodology allows us to grasp the dynamics of changes in the behavior of the test and explore the essence of co-occurring in this type of dementia, cognitive and language. In the first part of the approximate sketch is necessary to understand the practical part, the terminology concerning the psychology of memory, temporal horizon of human rights and basic definitions and assumptions Medical on Alzheimer’s. As part of the empirical analysis of the material shows that due to the disintegration of autobiographical memory adult has difficulty organizing his own experiences and events. As a result, systematically loses the ability to plan for the future, both the distant, perspective, and the next.
The prevalence of individual civilisational diseases has been constantly increasing in recent years. Their occurrence is related, among other factors, to changes in lifestyle (stress, low levels of physical activity, low-quality diet), increasing urbanisation and industrialisation (environmental pollution). Lifestyledependent diseases include type 2 diabetes and Alzheimer's disease which is not only related to lifestyle - one of the main risk factors is age. The increasing life expectancy of the population associated with the development of civilisation (health, social and welfare) therefore has a significant impact on its occurrence. In 2017, the number of people with diabetes was approximately 476 million, which represented an increase of 129.7% compared to 1990 [1]. For Alzheimer's disease, incidence and prevalence increased by 147.95% and 160.84% respectively between 1990 and 2019 [2]. The economic and social costs associated with the occurrence of these diseases are enormous [3,4]. Among the drugs used in the treatment of Alzheimer's disease, compounds of natural origin that have the cholinesterase inhibitor activity - the isoquinoline alkaloid galantamine - have been successfully used [101], as well as the semi-synthetic phisostigmine derivative isolated from Physostigma venenosum – rivastigmine (Fig. 4.) [5,6]. One of the most commonly used drugs in the treatment of diabetes is metformin, a synthetic derivative of galegin isolated from Galega officinalis (Fig. 2.) [7]. Natural-derived compounds can therefore be highly active and safe preparations used in both the prevention and treatment of certain diseases. The present work aims to review and summarise information on the potential use of herbaceous wild plants: Stellaria media, Epilobium angustifolium and Chenopodium album in the prevention and therapy of diabetes and Alzheimer's disease. Promising results have been obtained in both in vitro and in vivo studies on the potential use of extracts from these plants. They exhibited protective (neuroprotective activity, protection of organs from damage in the progress of diabetes, effects on body weight control and obesity reduction) and therapeutic (effects on lowering blood glucose levels, reducing insulin resistance, inhibitory effects on cholinesterase, α-glucosidase and α-amylase) activities. Polyphenolic compounds and flavonoids were shown to be important in determining the biological activity of the extracts. Available literature data indicate a high potential for the use of extracts obtained from these plants, both in the prevention and therapy of type 2 diabetes and Alzheimer's disease.
According to the statistics, there are currently 36 million people with dementia of the Alzheimer type in the world. The incidence of disease increases with the age. According to the Slovak Alzheimer’s Society in 2010, Slovakia had approximately 60,000 patients with Alzheimer’s disease and some other related diseases. Estimated number in 2030 is 180 000 patients. The disease also applies to the other ten thousand of nursemaids and family members who care for the disabled. For these reasons, it is necessary that the society should respond to the situation. And also providers of social services are professionally prepared to work with this type of client.
