Which of the following are common signs and symptoms of depression in children and adolescents? (Select all that apply)

Choice A reason: Persistent or frequent angry mood is a common symptom of depression in children and adolescents, often presenting as irritability rather than sadness. This reflects neurochemical imbalances affecting mood regulation, disrupting emotional stability, and is a key diagnostic criterion, making it a correct choice for depression symptoms. Choice B reason: Grandiose thinking is characteristic of mania or bipolar disorder, not depression. Depression in children typically involves low mood, anhedonia, or irritability, not inflated self-esteem or grandiosity, making this an incorrect symptom for depression and more aligned with other psychiatric conditions. Choice C reason: A sudden increase in energy and speech suggests mania or hyperactivity, not depression. Depression in children and adolescents is marked by low energy, fatigue, and reduced activity, making this an incorrect symptom, as it contrasts with the typical presentation of depressive disorders in this age group. Choice D reason: Loss of interest in previously enjoyed activities (anhedonia) is a hallmark of depression in children and adolescents. It reflects diminished pleasure due to altered brain reward pathways, particularly involving dopamine, and is a core diagnostic criterion, making this a correct and common symptom of depression. Choice E reason: Changes in sleep patterns and increased fatigue are common in pediatric depression, often presenting as insomnia or hypersomnia. These reflect disruptions in circadian rhythms and neurotransmitter imbalances, impacting energy levels and emotional regulation, making this a correct and frequently observed symptom in depressed children and adolescents.
