Which of the following is considered a sign of dementia?

The presence of changes in the ability to interpret what has been seen is a significant indicator of dementia. Individuals with dementia often experience difficulties with visual perception, which can manifest as trouble recognizing familiar objects, people, or even navigating their environment. This impairment goes beyond typical age-related changes and can severely affect an individual's understanding and interaction with their surroundings. Such alterations in perception can lead to confusion and disorientation, which are common symptoms of various types of dementia.

In contrast, normal forgetfulness is usually part of the aging process and does not imply a cognitive decline consistent with dementia. The recall of past events can remain intact for individuals with dementia, especially in the early stages, as long-term memory is often one of the last functions to be affected. Increased cognitive sharpness would actually be contrary to the effects of dementia, which typically results in a gradual decline in cognitive abilities. Understanding these distinctions is essential for recognizing signs of dementia and providing appropriate care and support.
