A nurse is assessing an adult's ability to adhere to their treatment plan during a routine medical appointment. Which of the following assessment findings should the nurse identify as a manifestation of dementia?

Withdrawal from social activities is a recognized manifestation of dementia. As dementia progresses, individuals commonly disengage from hobbies, friends, and social interactions they previously enjoyed. This occurs due to difficulty following conversations, embarrassment over memory lapses, loss of initiative (apathy), and declining ability to perform familiar tasks in group settings. Needing to retrace steps to locate a misplaced item is a normal age-related change in memory, not a hallmark of dementia. Similarly, forgetting names but later remembering them — a phenomenon known as the tip-of-the-tongue experience — is also considered a normal finding associated with aging rather than pathological memory impairment. Cataract-related visual changes are a physical, ophthalmological change of aging unrelated to cognitive decline or dementia. To distinguish dementia from normal aging, the nurse should focus on functional and behavioral changes such as social withdrawal, persistent confusion, impaired judgment, and an inability to complete familiar tasks — of which social withdrawal is the only finding listed here that qualifies as a dementia manifestation.
