Therapy With Older Adults: Dysthymia Case Study Analysis
This paper presents a clinical case study of a 69-year-old African-American male diagnosed with mild persistent depressive disorder (dysthymia) with anxious distress (DSM-5 300.4/F34.1). The paper covers the rationale for this diagnosis over alternative conditions such as major depressive disorder, identifies appropriate screening instruments including the Beck Depression Inventory and the Hamilton Depression Rating Scale, and outlines a three-pronged treatment strategy combining pharmacotherapy (Sertraline/Zoloft), cognitive behavioral therapy, and psychoeducation. Standard clinical guidelines for assessing and treating elderly clients are reviewed, and the paper concludes with a clinical note clarifying that depression, while more prevalent in older adults, is not a normal or inevitable aspect of aging.

What makes this paper effective
- The diagnosis is supported by explicit mapping of the client's symptoms to specific DSM-5 criteria (e.g., criteria B, E, G, and H), demonstrating diagnostic rigor rather than vague clinical impressions.
- The treatment rationale is evidence-based, citing meta-analyses to justify the prioritization of pharmacotherapy over psychotherapy for dysthymia, and selecting Sertraline specifically because of its lower weight-gain risk profile for an obese client.
- The paper moves logically from case presentation through diagnosis, differential analysis, and treatment, then broadens to population-level clinical guidelines and a psychoeducational note — a well-organized clinical reasoning progression.
Key academic technique demonstrated
The paper exemplifies evidence-informed clinical reasoning: each recommendation — choice of screening tool, pharmacological agent, and therapy modality — is explicitly linked to peer-reviewed literature and population-specific considerations (age, comorbidities, medication history). This "claim → evidence → application" pattern is a hallmark of graduate-level clinical case writing.
Structure breakdown
The paper opens with a detailed case summary and mental status findings, followed by a diagnosis section that maps symptoms to DSM-5 criteria. Subsequent sections address screening instruments, differential diagnoses, and a three-part treatment plan. The paper closes with age-specific clinical guidelines and a psychoeducational note on aging and depression. The structure mirrors a standard psychiatric clinical note expanded for academic purposes, totaling approximately 900 words of substantive analysis.
Case Summary
The client is a 69-year-old African-American male with one adult child and six grandchildren. His chief complaints are depression and anxiety. He reports that his father — his main source of support — is dying, and that he has been experiencing worsening symptoms of depression and anxiety as a result. Specific complaints include sleep difficulties, a feeling of "moving in slow motion," poor concentration when reading, and persistent fatigue. He has stopped going to his volunteer position at a nursing home and no longer enjoys time with his family.
The client has hyperlipidemia and was diagnosed with prostate cancer earlier this year, for which he has received psychotherapy. He has never been hospitalized for a psychiatric illness but has an extensive medication history that includes Duloxetine, Zoloft, Lexapro, Prozac, and Effexor taken over several years. He is currently prescribed Lorazepam. He reports that his mother had depression but denies any personal history of trauma or substance abuse.
A mental status examination reveals that the client is alert and oriented with intact memory. His speech is coherent, and he demonstrates abstract thought with good impulse control and sound judgment and insight throughout the interview. He exhibits a depressed mood and expresses frustration and sadness regarding his father's imminent death. His thought processes are goal-directed, though there is evidence of guilt and rumination. He is pleasant and maintains good eye contact throughout the clinical interview.
Diagnosis: Mild persistent depressive disorder (dysthymia) with anxious distress — 300.4 (F34.1).
Rationale for Diagnosis
The crucial feature of a dysthymic disorder is a depressed mood occurring for most of the day on most days for at least two years (APA, 2013). The client displays a sad mood throughout the clinical interview and is distressed about the anticipated loss of his father. He has been on Lorazepam, a benzodiazepine prescribed for sleep difficulties, for over one year, and was on other medications — including Duloxetine and Zoloft — before that. It is therefore likely that the client's depressive symptoms have persisted for more than two years.
During periods of depressed mood, the client reports insomnia, fatigue, poor concentration, and feelings of guilt or worthlessness — four symptoms under DSM-5 Criteria B. The DSM-5 criteria for dysthymia require a client to meet at least two of the Criteria B symptoms; this client meets four. Furthermore, his symptoms cause significant impairment in social and occupational functioning, evidenced by his withdrawal from his volunteer role at the nursing home (Criteria H). The client denies alcohol and substance use, so his symptoms cannot be attributed to the physiological effects of substances (Criteria G). There is also no history of psychotic symptoms, satisfying Criteria E.
The client reports difficulty concentrating and persistent worry about his father's death — both of which are indicators of anxious distress (APA, 2013). His symptoms therefore meet the criteria for mild persistent depressive disorder (dysthymia) with anxious distress.
Screening Tools and Assessment Instruments
The APA recommends several instruments for screening adult clients presenting with depressive symptoms. One of the most widely used is the Beck Depression Inventory (recommended for clients aged 13 to 80), which assesses the severity of depressive symptoms using 21 self-rated items (Wheeler, 2014). For this client, the PMHNP could also consider the Center for Epidemiological Studies Depression Scale (CES-D), recommended for clients from age 6 through older adulthood, which measures symptoms based on 20 self-reported items (Wheeler, 2014; APA, 2019).
The Hamilton Depression Rating Scale, recommended for use across the lifespan, would also be appropriate. It is clinician-administered and measures depression before, during, and after treatment using 21 items (APA, 2019). Additionally, the PMHNP could consider the Montgomery-Åsberg Depression Rating Scale (MADRS), recommended for individuals aged 18 and older, which measures depression severity using 10 items scored on a 7-point scale (APA, 2019).
