Answer: (A)

Depression in older adults often comes with cognitive complaints such as memory problems, trouble concentrating, and slowed thinking, which can resemble dementia. This overlap is why depression is frequently mistaken for a dementing process; the cognitive symptoms may be the dominant or early feature, sometimes called pseudodementia. Key to understanding is how the two differ in pattern and course. Depression has prominent mood symptoms (sadness, anhedonia, fatigue, guilt) and the cognitive issues are often not progressive and may improve with effective treatment. Dementia shows a steady, gradual decline across multiple cognitive domains (memory, language, executive function), with mood changes less central and with a worsening trajectory over time. In pseudodementia, patients may appear unusually concerned about their memory and may perform poorly on tests due to lack of effort but can show improvement as mood improves. True dementia, by contrast, tends to show consistent deficits and less motivation to engage in testing. Clinically, this means screening for mood symptoms when elderly patients present with cognitive complaints and re-evaluating cognition after optimizing treatment for depression. If cognition improves with antidepressant therapy or psychotherapy, that supports depression as the underlying issue. If deficits persist or worsen despite mood treatment, further evaluation for dementia is warranted.
