Background: Dementia is a progressive neurodegenerative condition whose global prevalence is rising in tandem with an aging population. It imposes significant personal, societal, and economic burdens, affecting not only those diagnosed but also their caregivers and communities. This narrative review critically evaluates the impact of dementia on quality of life, with a specific focus on the physical, emotional, and social dimensions affecting patients and caregivers across different stages of the disease. Methodology: A comprehensive review of 25 peer-reviewed articles and authoritative reports published between January 2011 and January 2025 was conducted. Databases searched included PubMed, Scopus, and Web of Science. Studies were selected based on their relevance to dementia subtypes, symptomatology, and quality-of-life outcomes, with emphasis on high methodological rigor and recent findings. Results: Dementia significantly impairs physical functioning through mobility decline, comorbid conditions, and loss of independence, factors that also burden caregivers. Emotionally, it leads to high rates of depression, anxiety, and identity erosion in patients, while caregivers experience chronic stress and grief. Socially, stigma, isolation, and inadequate community infrastructure exacerbate marginalization. These domains are interconnected, with deterioration in one often accelerating decline in others. Stage-specific challenges and sociocultural disparities further influence outcomes. Conclusion: Improving the quality of life in dementia requires a holistic, multidimensional approach. Interventions must address physical, emotional, and social needs concurrently while adapting to disease stage and cultural context. Personalized care, caregiver support systems, stigma reduction, and equitable access to services are essential to mitigating the wide-ranging impact of dementia.
