Dementia is a disease characterized by impaired cognitive function and irreversibly affects the ability to think, understand, learn, remember, coordinate and judge. The World Health Organization (WHO) estimates that approximately 50 million people globally have dementia, and the total number of people with dementia is projected to reach 82 million by 2030, and the global cost of dementia will be about $ 2 trillion. Alzheimer's dementia is the most common form of dementia and accounts for 60-70% of all dementias, with other major forms including vascular dementia, Lewy body dementia, and frontotemporal dementia. Impaired cognitive functions are the main symptoms of all forms of dementia and can be categorized into five main domains: memory, executive function, language, visual spatial abilities, personality, and behavior. The diagnosis is confirmed by one of the methods of imaging (neuroimaging), most often by computed tomography (CT) and magnetic resonance imaging (MR). The pharmacological gold standard for the treatment of dementia are cholinesterase inhibitors in combination with an NMDA receptor agonist. The extent of health care for patients with dementia depends on the stage of dementia, and most often includes the provision of assistance due to reduced ability to take care of themselves in the form of feeding, elimination of waste products and maintaining personal hygiene. The progression of dementia leads to a reduction in mobility and thus a high risk of falling, therefore nursing interventions should be aimed at encouraging movement and ensuring safe conditions for movement. In the late / terminal stage of dementia, patients are most often in delirium, unaware of themselves and their surroundings, and nursing interventions are aimed at preventing the complications of prolonged lying down. Providing psychological support to the patient, but also to his family, is extremely important during all stages of dementia. Additional education of nurses / technicians can facilitate the implementation of health care for patients with dementia and consequently lead to more favorable outcomes for patients and higher levels of satisfaction of nurses / technicians.
