What symptom would be least indicative of dementia in an elderly patient?

Agitation is often seen in various medical conditions, including anxiety disorders, depression, and even pain-related issues, rather than being a definitive marker of dementia itself. While it can accompany dementia, agitation does not specifically point to cognitive decline or memory impairment that are hallmark symptoms of the condition.

In contrast, impaired short-term memory, the inability to remember recent events, and loss of interest in activities are more directly related to cognitive changes commonly observed in dementia. Short-term memory impairment is especially crucial, as it typically signifies difficulties with new learning or recalling recent information, which are central deficits in dementia. Similarly, a loss of interest in previously enjoyed activities can reflect the apathy and social withdrawal often seen in dementia patients. Together, these symptoms create a clearer picture of cognitive decline than agitation alone.
