According to the World Health Organization, over 55 million people worldwide live with dementia, with Alzheimer’s dementia being the most common form. Alzheimer’s dementia is a neurodegen-erative disorder and a progressive disease that affects the brain, characterized by personality chang-es, memory loss, and reasoning abilities. An early sign of Alzheimer’s dementia is forgetfulness. The population equates forgetfulness with aging, which is the most common problem of late disease detection, thus we lose the opportunity to start the treatment process in time. Early diagnosis and treatment are essential for halting the progression of the disease. The main treatment of Alzheim-er’s dementia includes pharmacological and non-pharmacological treatment. The US Food and Drug Administration (FDA) has approved cholinesterase inhibitors (ChEIs) and the N-methyl-d-aspartate (NMDA) antagonist memantine as drugs for the symptomatic treatment of the disease (improving cognition and reducing loss of independence...). With non-pharmacological treatment, psychother-apies are organized, where it is discovered what was the trigger for the onset of the disease, and the adjustment of behavioral interventions in the environment, and nursing care is planned, which is carried out already at the patient’s admission. The staff caring for the patient monitors non-verbal communication, tries to communicate in such a way that sentences and questions are short and clear, requiring a simple answer. In a combination of pharmacological and non-pharmacological treatment, the symptoms can be significantly alleviated and the progression of the disease can be reduced. In recent decades, we have witnessed the growth of diseases, which is why intensive ef-forts of researchers are needed to develop better clinical tools and therapy. The development of new types of drugs that target different neurotransmitter systems, aimed at treating cognitive defi-cits and behavioral disorders. The aim and purpose of this case report is to describe the manner of occurrence, causes and factors of the disease, treatment, planning and implementation of nursing interventions, and to describe the prevention of the occurrence of the disease and clarify the pathology and pathophysiology.
