Dementia in the elderly is a common neurodegenerative disease worldwide. It is a clinical syndrome caused by the irreversible death of brain neurons due to various factors. Initially, the main symptom in patients is impaired memory function, which at this stage does not significantly affect work and life, and is not overly concerning. As the disease progresses, the cognitive functions of the elderly, including visuospatial skills, calculation abilities, and executive functions, are notably impaired. Changes in personality and behavior also occur. What is most feared in dementia? It is particularly concerning when elderly individuals go out on their own and then cannot find their way home, leading to situations where they may become lost. If the elderly are unable to find adequate food outdoors, or if the weather is too cold or too hot, their life safety can be severely threatened. Additionally, dementia patients might inadvertently turn on the gas at home and forget to turn it off, which can easily lead to accidents. These are the most feared incidents related to dementia in the elderly.
