Which of the following is NOT considered a sign of depression?

Anhedonia, changes in appetite, decreased energy, irritability, apathy, and low self-esteem are all recognized symptoms of depression that align with the criteria listed in diagnostic manuals such as the DSM-5. Each of these options reflects common emotional or behavioral manifestations seen in individuals suffering from depression.

On the other hand, apraxia refers specifically to the neurological inability to perform tasks or movements when asked, despite having the desire and physical ability to do so. It does not directly relate to the emotional or psychological symptoms typically associated with depression. Moreover, while fatigue can be a symptom of depression, the presence of apraxia does not correlate with the mood or cognitive aspects of the disorder. Therefore, identification of apraxia as part of the symptomatology of depression would not be accurate, making this option the one that does not fit within the typical signs of depression.
