ABC/123 Version X 1 The Case of the Sad Doctor CCMH/522 Version

The case involves a 55-year-old male dentist presenting with a month-long history of depressive symptoms, including persistent low mood, loss of interest, indecisiveness, feelings of guilt and hopelessness, and paranoia. He reports difficulty concentrating, anhedonia, and physical complaints such as weight loss, insomnia, decreased appetite and libido, constipation, and a sensation that his body is deteriorating with cancer. He has contemplated suicide but is deterred by his responsibilities.

The presentation of mood disturbances in this patient raises questions about the underlying psychiatric diagnosis, the potential severity of his condition, and appropriate treatment strategies. Several psychiatric conditions could account for his symptoms, but major depressive disorder (MDD) appears most consistent given the persistence, functional impairment, and physical symptoms.

Major depressive disorder (MDD) is a common and often debilitating mental health condition marked by persistent low mood and a loss of interest or pleasure, along with associated cognitive and physical symptoms. According to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), a diagnosis of MDD requires the presence of at least five symptoms during the same two-week period, representing a change from previous functioning, with at least one of the symptoms being depressed mood or loss of interest or pleasure (American Psychiatric Association, 2013).

In this case, the patient's symptoms align closely with the criteria: depressed mood, diminished interest in activities (including his professional work and tennis), significant weight loss, insomnia, psychomotor changes, fatigue, feelings of guilt and worthlessness, impaired concentration, and recurrent thoughts of death. His paranoia and physical complaints may suggest comorbid features or somatic preoccupations common in severe depressive episodes, particularly in older adults (Katon & Ciechanowski, 2014).

Differential Diagnosis

While MDD fits most clinical features, it is essential to differentiate this condition from other psychiatric or medical states that could present similarly. Bipolar disorder should be considered, but in the absence of manic or hypomanic episodes, depression remains unipolar. Psychotic depression could also be considered given paranoia and somatic fears, but without clear psychotic features such as hallucinations or delusions, MDD with mood-congruent psychotic features is more likely.

Other potential diagnoses include grief or bereavement, but the absence of a recent loss and the severity of symptoms favor a clinical depression. Medical conditions such as hypothyroidism, vitamin deficiencies, or neurodegenerative diseases could also mimic depressive symptoms and should be ruled out through appropriate investigations (Mitchell et al., 2017).

Pathophysiology and Contributing Factors

The biological underpinnings of depression involve complex alterations in neurotransmitter systems, especially serotonin, norepinephrine, and dopamine, and dysregulation of neuroendocrine pathways, including the hypothalamic-pituitary-adrenal (HPA) axis (Krishnan & Nestler, 2008). In older adults, biological vulnerabilities may be compounded by medical comorbidities, social isolation, and functional impairments.

Psychosocial factors, such as stress, personality traits, and lack of social support, also contribute to the development and persistence of depression. Chronic stress and feelings of hopelessness can exacerbate neurochemical imbalances, creating a vicious cycle (Hammen, 2005).

Management and Treatment

The management of major depressive disorder entails pharmacological, psychotherapeutic, and social interventions. Selective serotonin reuptake inhibitors (SSRIs) are typically first-line medications due to their favorable side effect profile and efficacy (Bailey et al., 2017). Given the physical complaints and the patient’s age, a thorough medical evaluation should precede pharmacotherapy to rule out organic causes.

Psychotherapy, especially cognitive-behavioral therapy (CBT), has demonstrated effectiveness in addressing maladaptive thought patterns, fostering behavioral activation, and improving coping skills (Hollon et al., 2002). A combined approach yields the best outcomes, especially in severe cases.

Addressing psychosocial factors, such as social isolation or role changes, is also crucial. Engaging family members and support networks can enhance treatment adherence and improve prognosis (Harvey et al., 2014).

Prognosis and Follow-up

Patients with depression, particularly in older adults, require ongoing monitoring for treatment response, side effects, and risk of suicide. Although the patient reports no specific positive events, his expressed suicidal ideation warrants careful risk assessment and possibly safety planning. Close follow-up, including regular clinical assessments and possibly involving a multidisciplinary team, can improve outcomes (Popp et al., 2015).

Conclusion

This case exemplifies the complexity of diagnosing and managing depression in middle-aged adults. The patient's presentation aligns with a diagnosis of major depressive disorder, necessitating a comprehensive treatment approach combining pharmacotherapy, psychotherapy, and social support. Early intervention is critical to prevent progression, improve quality of life, and reduce suicide risk.
