Dementia is a chronic and progressive brain disorder impacting memory, thinking, behavior, and daily activities. Primarily affecting older adults, it is not a normal part of aging. Alzheimer's disease is the most common cause, but other types include vascular dementia, Lewy body dementia, and frontotemporal dementia. Symptoms range from memory loss and confusion to mood changes and communication difficulties. While currently incurable, early diagnosis and supportive care can enhance quality of life. Effective management involves medical treatment, lifestyle adjustments, and support from caregivers and healthcare professionals
