What cognitive symptoms are included in the depression diagnostic criteria?

The correct answer identifies cognition or concentration loss as a key cognitive symptom included in the depression diagnostic criteria. In the context of depression, cognitive symptoms often manifest as difficulties in focusing, making decisions, or processing information. These cognitive impairments can significantly affect an individual's ability to function in daily life, contributing to the overall experience of the depressive episode.

While memory loss can indeed be observed in some individuals with depression, it is not universally recognized as a core cognitive symptom within the diagnostic criteria. Similarly, decision-making difficulties can fall under broader cognitive and concentration issues but are not specifically outlined as separate criteria. Therefore, focusing on cognition or concentration loss encapsulates a vital aspect of the cognitive symptoms experienced in depression, making it the most accurate choice in this context.
