Which of the following is NOT a common symptom in older adults experiencing depression?

Increased socialization is generally not associated with depression in older adults and therefore is the correct choice. When individuals are experiencing depression, they often exhibit a withdrawal from activities and interactions that they once enjoyed, leading to increased social isolation rather than socialization.

Common symptoms of depression in older adults typically include withdrawal from activities, where they may lose interest in hobbies or social engagements that they previously participated in. Feelings of hopelessness are another hallmark of depression and can manifest as a pervasive sense of despair or an outlook that things will not improve. Additionally, cognitive issues such as memory problems can occur, as depression can impact concentration and cognitive functioning, leading to what may sometimes be referred to as "pseudodementia," where cognitive deficits appear due to the depressive state rather than a primary neurodegenerative disease. Thus, recognizing increased socialization as not aligning with the behavioral patterns typical of depression in older adults is crucial in understanding the disorder's presentation in this demographic.
