Depression in Adolescents: Symptoms, Diagnosis, and Treatment
This paper examines depression in adolescents through a combination of clinical overview and detailed case analysis. It begins by defining affective disorders and outlining the WHO classification of depressive episodes by severity. The paper then applies DSM-5 diagnostic criteria to a clinical case involving a 16-year-old female hospitalized for suicidal ideation, exploring her differential diagnosis, psychosocial history, familial influences, and cultural considerations. Treatment approaches discussed include cognitive behavioral therapy, antidepressant pharmacotherapy—specifically SSRIs—antipsychotic medications, and family-based psychoeducational interventions. The paper concludes by emphasizing the need for further research into childhood and adolescent depression treatment.

What makes this paper effective
- The paper integrates theoretical frameworks (WHO classification, DSM-5 criteria) with a detailed clinical case, grounding abstract diagnostic categories in a concrete patient presentation.
- It addresses multiple dimensions of the patient's condition — biological, familial, environmental, and cultural — reflecting a holistic biopsychosocial approach.
- The treatment section is well-organized, distinguishing between psychotherapy, pharmacotherapy, and psychosocial interventions, with specific evidence cited for each modality.
Key academic technique demonstrated
The paper demonstrates applied diagnostic reasoning: it systematically works through DSM-5 criteria, differential diagnoses, and comorbid conditions before arriving at a multi-axis diagnosis. This method of ruling out competing diagnoses while building a cumulative clinical picture is a core technique in clinical case writing and psychiatric assessment.
Structure breakdown
The paper opens with a theoretical overview of affective disorders and WHO severity classifications, then transitions to DSM-5 criteria specific to children and adolescents. The clinical case is introduced mid-paper and anchors the remaining sections, which cover differential diagnosis, psychosocial history, familial and cultural influences, and treatment. The final sections broaden back out to evidence-based pharmacological and psychosocial interventions, closing with a research gap observation. This funnel-then-broaden structure is well-suited to case study writing.
Overview of Affective Disorders and Depressive Episodes
The link between symptoms, etiology, core biochemical processes, treatment outcome, and treatment response of affective (mood) disorders is yet to be adequately understood to allow for categorization that meets universal approval. Still, an attempt must be made in this regard, and researchers propose a potentially acceptable framework derived from extensive consultation.
In the case of affective disorders, the basic disturbance is a change in affect (mood), typically extreme elation or depression, with or without related anxiety. An overall change in activity level generally accompanies this mood change, and a majority of other related symptoms will either be recognized within the context of these changes or will be secondary to them. Most disorders have a tendency toward repetition, and the commencement of individual bouts is usually linked to stressful circumstances or events.
The key criteria for classification of affective disorders have been selected for practical purposes, in that they permit easy identification of common clinical problems. Single spells are distinguished from multiple-episode or bipolar disorders, since a considerable percentage of clients experience only a single episode of illness. Severity is accorded importance owing to its treatment implications as well as for providing different service levels. Differentiating between severity levels remains an ongoing challenge — the three levels (severe, moderate, and mild) are specified because of their preference among many clinicians (WHO, n.d., p. 94).
Typically, in severe, moderate, and mild depressive episodes, the patient normally experiences a depressed mood, reduced energy, and loss of enjoyment and interest, resulting in diminished activity and increased fatigability. One common symptom is noticeable tiredness following minimal effort. Other symptoms that commonly occur include:
- Disturbed sleep
- Lowering of self-confidence and self-esteem
- Ideas of unworthiness and guilt (even in mild depression)
- Acts or ideas of suicide or self-harm
- Pessimistic, hopeless views of the future
- Diminished appetite
- Decreased attention and concentration
The low mood does not vary much from day to day and is typically unresponsive to circumstances, but may nevertheless display a distinctive diurnal variation as the day progresses. As with manic episodes, the clinical presentation of depression shows marked individual variation. Among adolescents in particular, atypical presentations are especially common. In some instances, motor agitation, anxiety, and distress may be more pronounced, and additional features such as irritability, histrionic behavior, hypochondriac preoccupations, excessive drinking, and exacerbated pre-existing obsessional or phobic symptoms might obscure the underlying mood change. For mild-to-severe depressive episodes, a minimum of two weeks is required for diagnosis; however, in cases of abnormally severe symptoms and rapid onset, shorter diagnostic periods may be reasonable.
Some patients may develop distinctive features recognized as having particular clinical significance. The most characteristic examples of depression's "somatic" symptoms include:
- Loss of pleasure or interest in normally enjoyable activities
- Waking earlier than usual (at least two hours early)
- Lack of any emotional reaction to ordinarily pleasurable events and surroundings
- Weight loss (usually defined as a minimum of 5% body weight loss within one month)
- Worse depression in the daytime
- Noticeable loss of libido and appetite
- Objective evidence of psychomotor agitation or retardation (reported or noted by others)
This somatic syndrome is generally not considered present unless at least four of the aforementioned symptoms are clearly identified.
The mild-moderate-severe categorization of depressive episodes should be used only for the first episode. Any subsequent episodes should be categorized under a subdivision of recurring depressive disorder. These severity grades cover the various clinical states that psychiatrists encounter across diverse settings. People suffering from mild depression commonly seek treatment at general medical and primary care settings, while psychiatric inpatient clinics mostly deal with those suffering from severe depression (WHO, n.d.).
DSM-5 Diagnostic Criteria for Adolescent Depression
According to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), severe depressive conditions are characterized by a sense of desolation, sorrow, and guilt; sleep disturbances; and loss of interest in activities. In a majority of cases, people suffering from major depression also undergo significant weight change.
Acute depression has been diagnosed across all age groups and is seen most commonly in females. There are many effective treatment options for depressive disorders, but if left untreated, severe depressive disorder may end in suicide (Sheaffer, 2016). According to DSM-5 criteria, adolescents or children may be diagnosed as depressed if a minimum of five symptoms are present over a two-week diagnostic period, including either (1) irritable or depressed mood or (2) loss of pleasure or interest, along with any three of the following symptoms:
- Hypersomnia or insomnia
- Considerable appetite or weight change (over 5% of body weight within one month)
- Fatigue or loss of energy
- Psychomotor retardation or agitation
- Indecisiveness or reduced concentration
- Persistent thoughts of suicide or death
- Feelings of guilt or worthlessness
Aside from the aforementioned DSM-5 criteria, teenagers and children might also experience:
- Constant irritable or sad mood
- Feelings of boredom
- Frequent non-specific or vague physical complaints
- Substance or alcohol abuse
- Frequent truancy or poor academic performance
- Recklessness
- Increased anger, hostility, or irritability
These symptoms must bring about considerable functional impairment or distress. Depression scales such as the Reynolds Adolescent Depression Inventory, Beck Depression Inventory, and Children's Depression Inventory may be employed for establishing baseline functioning, measuring severity, and monitoring treatment progress (MDwise, 2010).
