Introduction and purpose. The prompt asks for a structured clinical reasoning exercise focused on selecting a DSM-5 diagnosis, coding it appropriately, and outlining a rationale that ties observed signs and symptoms to DSM-5 criteria. It also requires consideration of supporting tests, differential diagnoses, treatment strategies (including pharmacology, psychotherapy, and psychoeducation), safety planning, and the standard guidelines used to assess and treat the patient. Additionally, it asks for a clinical note addressing whether depression is a normal part of aging. This paper provides a reasoned synthesis suitable for an academic clinical write-up while emphasizing evidence-based considerations relevant to older adults who may present with depressive symptoms. (American Psychiatric Association, 2022; NICE, 2020)

Proposed diagnosis and DSM-5-TR code. The most likely diagnosis to consider given an older adult with persistent depressive symptoms, functional impairment, and associated somatic complaints is Major Depressive Disorder, recurrent, moderate (DSM-5-TR code F33.1). This choice aligns with the DSM-5-TR criteria, which require: (a) at least five of the core depressive symptoms during a two-week period, with at least one being depressed mood or anhedonia; (b) clinically significant distress or impairment; (c) there is no history of a manic, hypomanic, or mixed episode; (d) symptoms are not attributable to another medical condition or substance use; and (e) symptoms are not better explained by another psychiatric disorder (American Psychiatric Association, 2022). In older adults, presentation can include fatigue, sleep disturbance, appetite changes, psychomotor changes, and cognitive complaints that may mimic cognitive decline, underscoring the need for careful differential assessment (Blazer, 2019; Alexopoulos, 2005). (APA, 2022; Blazer, 2019; Alexopoulos, 2005)

Rationale and linkage to DSM-5-TR criteria. The rationale rests on linking observed signs and symptoms to DSM-5-TR diagnostic criteria. If the patient experiences persistent depressed mood or anhedonia most days for at least two weeks, accompanied by at least four other symptoms such as change in sleep, appetite/weight, fatigue, psychomotor agitation or retardation, feelings of worthlessness or excessive guilt, diminished ability to concentrate, or recurrent thoughts of death, and there is meaningful impairment in social, occupational, or other functioning, Major Depressive Disorder becomes the most parsimonious diagnosis (American Psychiatric Association, 2022). In geriatric populations, differential diagnosis must carefully rule out major medical contributors (thyroid disease, anemia, infection, metabolic abnormalities), medications with depressive side effects, and neurocognitive disorders that could explain or complicate symptom presentation (Mayo Clinic, 2023; NIA, 2022). The linkage is strengthened when screening tools and objective assessments confirm persistent affective disturbance with impairment, in the absence of episodes of mania or hypomania, and when temporal pattern and context (e.g., bereavement, chronic illness, bereavement-associated neurovegetative symptoms) are integrated into the diagnostic reasoning. (APA, 2022; Mayo Clinic, 2023; NIA, 2022)

Tests and tools to identify the diagnosis. A systematic approach to identification includes: (1) structured clinical interview and mood assessment to document duration, number of symptoms, and impairment; (2) standardized screening instruments such as the Patient Health Questionnaire-9 (PHQ-9) or the Geriatric Depression Scale (GDS) to quantify severity and track changes; (3) cognitive screening with brief tools like the Montreal Cognitive Assessment (MoCA) or Mini-Mental State Examination (MMSE) to distinguish depressive symptoms from cognitive impairment; (4) medical work-up to rule out secondary causes (complete blood count, thyroid-stimulating hormone, vitamin B12, folate, metabolic panel) and consideration of neuroimaging if neurocognitive symptoms or focal deficits are present; and (5) collateral information from family or caregivers to gain perspective on functioning and symptom trajectory (Reynolds & Cuijpers, 2010; Blazer, 2019; NICE, 2020). These steps help ensure that the diagnostic picture reflects a primary mood disorder rather than a somatic or cognitive comorbidity. (Reynolds & Cuijpers, 2010; Blazer, 2019; NICE, 2020)

Differential diagnoses to consider. Several conditions can mimic or accompany late-life depression and warrant careful differential diagnosis: (a) Adjustment disorder with depressed mood when symptoms are in response to a identifiable stressor and do not meet full criteria for MDD; (b) Bipolar spectrum disorders, given the possibility of a manic or hypomanic history; (c) Major neurocognitive disorder or other dementias presenting with depressive features or pseudodementia; (d) delirium or medication-induced mood changes; (e) hypothyroidism, anemia, vitamin B12 deficiency, electrolyte disturbances, chronic inflammatory states; (f) chronic pain conditions and sleep disorders; (g) substance-induced mood disorder, including alcohol or sedative misuse; and (h) grief-related depressive episodes that persist beyond normative bereavement and cause functional impairment (Alexopoulos, 2005; Blazer, 2019; APA, 2022). A comprehensive assessment helps distinguish MDD from these alternatives and informs treatment planning. (Alexopoulos, 2005; Blazer, 2019; APA, 2022)

Treatment strategy and rationale. A multi-modal treatment plan for late-life depression typically includes pharmacotherapy, psychotherapy, safety planning, and psychoeducation, tailored to the patient’s comorbidity, functional status, and preferences. Pharmacotherapy commonly begins with a selective serotonin reuptake inhibitor (SSRI) such as sertraline or escitalopram due to favorable tolerability profiles in older adults, with gradual titration and close monitoring for side effects (e.g., hyponatremia, falls risk, hyponatremia risk, sleep disturbances). If SSRI response is inadequate or contraindicated, a serotonin-norepinephrine reuptake inhibitor (SNRI) such as venlafaxine or duloxetine may be added or substituted, mindful of blood pressure and hepatic function. In cases of partial response or contraindications to antidepressants, augmentation strategies (e.g., mirtazapine, bupropion) can be considered, again with attention to metabolic and seizure risk. For severe, refractory, or psychotic depression, electroconvulsive therapy (ECT) remains a highly effective option with favorable safety in older adults when indicated. Parallel to pharmacotherapy, evidence-based psychotherapies such as cognitive-behavioral therapy (CBT) or problem-solving therapy (PST), and interpersonal therapy (IPT) adapted for older adults, should be offered, particularly when cognitive impairment is mild or absent and social support is available (APA, 2022; NICE, 2020). Psychoeducation for patients and caregivers about symptom trajectories, treatment expectations, adherence, and safety planning is essential. (APA, 2022; NICE, 2020)

Safety considerations, pharmacology, diagnostics, psychotherapy, and psychoeducation. Safety must be embedded in the care plan given elevated suicide risk in some older adults with depression. A structured safety plan, crisis resources, and caregiver involvement are important, particularly when there is expressed or emergent suicidal ideation. Pharmacologic treatment requires dose initiation at a low level with slow titration and monitoring of interactions, comorbidities, and polypharmacy risks common in older adults. Psychopharmacology should be chosen with regard to medical comorbidity, renal/hepatic function, cardiovascular status, and concomitant medications. Psychotherapies such as CBT or IPT can be delivered in person or via telehealth, with adaptations for sensory or cognitive limitations. Psychoeducation should cover the purpose of treatment, expected timelines, potential adverse effects, and how to monitor progress. Guidelines from major bodies emphasize integrated, patient-centered care and regular re-evaluation of diagnosis and treatment effectiveness. (Chaudron et al., 2013; APA, 2022; NICE, 2020; Mayo Clinic, 2023)

Standard guidelines for treating or assessing this patient. The treatment plan should be informed by established guidelines that address late-life depression, including APA practice guidelines for MDD, NICE recommendations for recognition and management, and geriatric-specific considerations. These guidelines advocate for an integrated approach combining pharmacotherapy and psychotherapy, tailored to medical comorbidity and functional status, with ongoing monitoring for efficacy and safety. In older patients, guidelines consistently highlight the importance of starting with low-dose antidepressants, monitoring for adverse effects, assessing cognitive status, ensuring social support, and considering non-pharmacological interventions such as PST, CBT, and IPT. (APA, 2022; NICE, 2020)

Clinical note: Is depression a normal part of aging? Depression is not a normal part of aging. While mood changes, loss of loved ones, chronic illness, and social isolation can contribute to depressive symptoms in older adults, clinical depression is a treatable disorder that warrants investigation and intervention. Normal aging may involve slower processing or temperament changes, but persistent depressed mood and anhedonia with functional impairment should prompt a diagnostic workup for major depressive disorder and other conditions. Distinguishing grief from clinical depression is critical; if depressive symptoms persist beyond what would be expected for bereavement or meet full DSM-5-TR criteria, a mood disorder diagnosis should be considered and treated accordingly. (Mayo Clinic, 2023; Blazer, 2019; APA, 2022)

Conclusion. The diagnostic process for older adults presenting with depressive symptoms should begin with a careful DSM-5-TR-based assessment, followed by targeted medical screening, cognitive evaluation, and consideration of comorbidities. The most fitting DSM-5-TR code in many cases is F33.1 (Major depressive disorder, recurrent, moderate), but clinicians should verify recurrence pattern, severity, and functional impact prior to finalizing the diagnosis. A layered treatment approach—combining pharmacotherapy, psychotherapy, safety planning, and psychoeducation—offers the best chance for symptom remission and functional recovery when tailored to the patient’s medical and social context. Regular follow-up and re-evaluation ensure responsiveness to treatment and adjustment for competing diagnoses or new medical issues. (APA, 2022; NICE, 2020)
