When does a person get worse and how much time do they have with dementia?

A person with dementia may experience a decline in cognitive and functional abilities over time, with progression varying widely among individuals. Factors such as the type of dementia, overall health, and support systems can influence the rate of decline. Typically, dementia progresses over several years, but some individuals may experience rapid deterioration, while others may maintain function for a longer period. It's essential for families and caregivers to seek medical advice for tailored information regarding prognosis and care planning.
