Dementia, in its various forms, is characterized by a generalized cognitive decline that can significantly compromise personal autonomy and quality of life. Mild Cognitive Impairment (MCI), although not classified as an overt form of dementia, represents a condition at evolutionary risk and is considered a crucial transitional stage for the early detection of cognitive decline. Understanding the impact of dementia and MCI from a multidimensional perspective is now essential to fully grasp the repercussions of these conditions on patients' daily lives. The present protocol aims to investigate key aspects related to these disorders, with the objective of exploring cognitive functioning, the degree of impairment in activities of daily living, and the presence of neuropsychiatric symptoms. Through an integrated and multidisciplinary approach, the study seeks to enhance clinical management and patient care, promoting more effective, targeted, and personalized interventions.
