Dementia is a broad term used to describe symptoms resulting from brain damage caused by various diseases or small strokes. It is a progressive condition, meaning that symptoms will worsen over time. The rate of decline depends on the type and stage of dementia, as well as individual factors. The severity of dementia can be influenced by factors such as the person’s overall health, lifestyle, adherence to medication, the specific type of dementia, and the age at which symptoms begin.
