Dementia is a progressive neurological disorder that affects cognitive function, memory, and behavior. It is not a specific disease but rather a term used to describe a wide range of symptoms associated with a decline in mental abilities severe enough to interfere with daily life. The most common cause of dementia is Alzheimer’s disease, but other conditions like vascular dementia, Lewy body dementia, and frontotemporal dementia can also lead to its development.

People with dementia may experience memory loss, difficulty with language and communication, impaired judgment, disorientation, and changes in mood and behavior. As the condition progresses, individuals may struggle with basic tasks such as dressing, eating, and maintaining personal hygiene. Dementia can have a significant impact on a person’s independence, relationships, and overall quality of life.
