Dementia is a broad term used to describe a decline in cognitive function that interferes with daily living. It encompasses a range of symptoms; including memory loss, impaired reasoning, difficulty with problem-solving, and changes in behavior or social abilities. Dementia is not a single condition, but rather a collection of symptoms caused by various underlying diseases or disorders.

Alzheimer’s disease is the most prevalent form of dementia, responsible for approximately 60–80% of all cases. It is a progressive neurological disorder that gradually damages areas of the brain responsible for memory, thinking, and language. Over time, individuals with Alzheimer’s may experience confusion, disorientation, and challenges with communication and self-care.
