For a diagnosis of dementia, which of the following criteria must be met?

Unexplained memory loss
A limitation in everyday life due to cognitive change
A family history of dementia
Age over 65 years

The correct answer is: A limitation in everyday life due to cognitive change

A diagnosis of dementia requires that there be a limitation in everyday life due to cognitive change. This criterion emphasizes the functional impact of cognitive decline, meaning that the individual experiences difficulties in performing daily activities, such as managing finances, handling personal care, or following conversations. It reflects the idea that dementia is not merely a collection of symptoms but rather a significant decline in cognitive abilities that directly affects one's capacity to function independently in society. Other considerations, such as unexplained memory loss, family history, or age over 65, can be associated with dementia, but they are not definitive criteria on their own for diagnosis. Memory loss can occur for various reasons that are not dementia-related, and having family history can increase risk, but it does not constitute a diagnosis. Age can also be a risk factor, but it does not automatically indicate that someone has dementia if they meet no other criteria. Therefore, the focus is on the observable effects of cognitive changes on daily living.
