Mental disorders in geriatric age Introduction: Mental illness is a common but often neglected illness in the elderly. In the elderly population, the most common mental disorders are anxiety and depression and Alzheimer's disease, but due to stigma, misinformation and beliefs about aging, people often do not receive adequate care, and treatment is often reduced to pharmacological treatment, which rarely solves mental health and patient's well-being. Addressing mental health issues in older populations requires more attention, even more because anxiety or depression symptoms can indicate even physical illness, but also physical ailments can indicate mental health problems. Procedures: While writing this final paper, secondary data sources were used, ie sources collected from previous professional and scientific research. Professional and scientific databases available online were searched. Overview: Mental illnesses are common in old age, and their prevalence increases with the aging of population. Because of their severe consequences, mental illness in late life can be considered an important public health problem. Depression and bipolar disorder in the elderly are associated with medical comorbidities and cognitive decline, with an increased risk of dementia, suicide, and overall mortality. Conclusion: In developing the nursing profession and science, it is important to recognize the unique needs of the elderly population and focus even more on the field of mental illnesses. Although the elderly may have different worries and problems, the task of the nurse is to provide them with psychological well-being and support, as well as care and nursing that helps them to perform their daily activities independently for as long as possible.
