Psychopharmacology Case Studies: GAD and Depression
This paper presents three psychopharmacology case studies exploring the etiology, diagnosis, and treatment of generalized anxiety disorder (GAD) and depression across different patient populations. The first case examines GAD in an adolescent presenting with chronic worry, insomnia, and irritability, with treatment options including cognitive behavioral therapy and antidepressants. The second case addresses a child exhibiting symptoms consistent with both depression and hypothyroidism, highlighting the role of family, school, and environmental factors in diagnosis and treatment. The third case focuses on a 48-year-old woman experiencing depression following spousal bereavement, with discussion of vascular depression, DSM-5 diagnostic criteria, and complementary treatment approaches including psychotherapy and alternative medicine.
- Case 1: Generalized Anxiety Disorder (GAD): GAD etiology and symptoms in an anxious adolescent
- Diagnosis of GAD: DSM-5 criteria and clinical evaluation for GAD
- Treatment and Management of GAD: CBT, antidepressants, and lifestyle strategies for GAD
- Case 2: Depression and Hypothyroidism in a Child: Depression and hypothyroidism as differential diagnoses in a child
- Diagnosis and Treatment of Childhood Depression: Interviewing, questionnaires, Prozac, and psychotherapy for children
- Case 3: Depression in an Older Adult: Bereavement-triggered depression and vascular factors in a 48-year-old woman

What makes this paper effective
- Applies a consistent three-part structure (etiology, diagnosis, treatment) across all three cases, making the analytical framework easy to follow.
- Integrates DSM-5 diagnostic criteria directly into clinical reasoning, demonstrating familiarity with standard psychiatric classification tools.
- Considers differential diagnoses, such as hypothyroidism alongside depression in Case 2, showing critical thinking beyond a single-label approach.
- Addresses patient-specific factors (age, life circumstances, family context) that shape both diagnosis and treatment selection.
Key academic technique demonstrated
The paper demonstrates applied clinical reasoning by moving systematically from possible etiologies to formal diagnostic criteria to individualized treatment recommendations. Each case uses published criteria (DSM-5) and named pharmacological agents with their brand equivalents, grounding the discussion in professional psychopharmacology practice rather than general description.
Structure breakdown
The paper is organized into three discrete case studies. Each case opens with possible etiologies, proceeds through formal diagnostic considerations, and concludes with management and treatment recommendations. This parallel structure across all three cases reinforces the clinical method and makes comparative reading straightforward. References follow APA format and draw from clinical handbooks and reputable health information sources.
Case 1: Generalized Anxiety Disorder (GAD)
Possible Etiology
Generalized anxiety disorder (GAD) is a widespread anxiety condition characterized by chronic worrying, tension, and nervousness. This is distinct from a phobia, which involves fear of something specific or a particular situation. GAD diffuses a feeling of dread and unease across all aspects of a person's life. The anxiety is not as intense as a panic attack but lasts much longer, consequently lowering the general quality of life over an extended period. Regardless of whether a person is aware that their worrying is exaggerated, or believes that such worries protect them in some way, the consequence is the same: it is impossible to deliberately turn off the anxiety. Worries form an endless stream that flows through the mind (Segal, 2016). The first patient in this case study presents as a possible GAD case, as his worrying is now significantly affecting his quality of life, with anxiety and lack of sleep leading to mood swings and irritability.
Diagnosis of GAD
In order to assist the patient in dealing with generalized anxiety disorder, the health expert may conduct a physical examination to establish whether there is an underlying condition connected to the anxiety; request urine and blood tests if a medical condition is suspected; ask the patient pointed questions about his medical history and symptoms; and employ psychological assessment tools to determine a diagnosis.
Many experts apply the criteria laid out in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), published by the American Psychiatric Association, to investigate mental health conditions. The manual is also used by insurance companies in their compensation analysis processes.
The DSM-5 criteria for GAD include: exaggerated anxiety experienced on most days of the week about numerous events for a period spanning six months or longer; difficulty controlling the worry; and the presence of at least three of the following symptoms in adults — fatigue, restlessness, irritability, muscle tension, sleep problems, and concentration difficulties. The patient already presents with anxiety, sleep issues, and irritability. The following will therefore be examined in his case: whether his anxiety causes him significant distress and negatively disrupts his daily life; and whether his anxiety has no apparent link to a medical condition such as post-traumatic stress disorder, a physical illness, or substance abuse.
