The case involves a physician with a complex and long-term unstable mood disorder, raising questions about whether the patient has a mood disorder, a personality disorder, or both. The primary challenge is how to treat such a difficult patient effectively. To evaluate the patient, specific questions should be asked to gather relevant clinical information, including inquiries about the patient's mood episodes, behavioral problems, and history of mood fluctuations. Additionally, feedback from significant others in the patient's life such as family members and close contacts is essential for a comprehensive assessment. Appropriate physical exams and diagnostic tests, including metabolic panels, liver function tests, and assessments for diabetes, should be conducted to rule out physiological causes and monitor for medication side effects. Given the risk of suicide in mood disorders, screening with tools like the Columbia-Suicide Severity Rating Scale is critical. Differential diagnoses include recurrent major depression with anxious/dysphoric temperament, Bipolar II disorder, and a cluster B personality disorder, with the most likely being recurrent major depression with anxious features. Treatment options involve mood stabilizers like Lithium or Lamictal, with careful monitoring of renal function, liver function, and metabolic syndrome development, alongside regular lab testing. Medication management must be tailored to the individual, considering potential side effects, comorbidities, and race-related dosing differences. Continuity of care involves structured follow-up visits to assess medication efficacy and adherence. Ethical considerations include close monitoring, especially since the patient is a physician who may self-prescribe or disregard treatment recommendations. The complexity of treating challenging cases emphasizes the importance of collaborative care, ongoing assessment, and patient safety. Overall, a multidisciplinary, patient-centered approach is essential for managing such complicated mood disorders effectively.

Treating complex mood disorders, particularly in difficult patients such as physicians who self-prescribe, requires a comprehensive, nuanced approach that addresses both the clinical presentation and the underlying psychosocial factors (American Psychiatric Association, 2013). When assessing whether a patient has a mood disorder, a personality disorder, or both, clinicians must undertake a thorough and systematic evaluation, incorporating detailed history-taking, collateral information gathering, and appropriate laboratory and diagnostic testing.
Diagnostic Evaluation: History and Mental Status Examination
The initial step in diagnosis involves detailed questioning about the patient's mood episodes, behavioral patterns, and functional impairment. Asking about periods of elevated mood, racing thoughts, sleep disturbances, and impulsivity helps differentiate between bipolar disorder and unipolar depression. For instance, questions like "Have there been times when your energy levels spiked, and your thoughts felt racing or uncontrollable?" can discern manic or hypomanic episodes (Hirschfeld, 2002). Further, inquiries about the impact of these symptoms on occupational, social, and familial functioning provide insight into the severity and chronicity of the disorder (Hirschfeld, 2002).
Collateral information, especially from significant others, enhances diagnostic accuracy. For example, questioning family members about observed mood swings, irritability, or impulsive behaviors that the patient may underreport is crucial. Questions such as "Have you noticed any periods where the patient seemed unusually energetic, irritable, or had decreased need for sleep?" can provide corroborative evidence (Stahl, 2013). This is particularly relevant for differentiating bipolar disorder from personality disorders, which often involve pervasive patterns of behavior rather than episodic mood changes.
A comprehensive mental status examination assesses cognitive functioning, presence of psychotic features, and risk factors such as suicidal ideation. The Columbia-Suicide Severity Rating Scale (C-SSRS) provides a quantitative measure of suicidal thoughts and intent, vital for risk stratification (Columbia-Suicide Severity Scale, 2016). The exam also includes vital signs, physical assessment, and laboratory investigations to identify physiological contributors or medication side effects.
Physical Tests and Laboratory Studies
Laboratory evaluations are integral to ruling out medical conditions that may mimic or exacerbate mood symptoms. These include a Complete Metabolic Panel (CMP) to assess renal and hepatic function, Hemoglobin A1c for diabetes screening, and liver function tests. Since mood stabilizers such as Lithium are nephrotoxic, baseline and periodic renal function tests are mandated (Tolliver & Anton, 2015). Thyroid function tests are also essential, as hypothyroidism can present with depressive symptoms.
Psychiatric pharmacotherapy requires careful monitoring of side effects. Patients on antipsychotics need metabolic panels to detect potential metabolic syndrome, including weight gain, dyslipidemia, and glucose intolerance. Regular lab tests every 3-6 months are recommended for patients on such medications (Stahl, 2013). Urine drug screens are also critical, as illicit substance use can complicate mood disorder management.
Differential Diagnoses and Most Probable Diagnosis
The differential diagnoses include recurrent major depression with anxious/dysphoric features, Bipolar II disorder, and a cluster B personality disorder such as borderline or narcissistic personality disorder. Each diagnosis has distinctive features: mood episodes in bipolar disorder are episodic with distinct periods of normalcy; personality disorders entail chronic interpersonal and behavioral patterns. In this case, recurrent major depression with an anxious/dysphoric temperament appears most probable, given the patient's predominant depressive symptoms, historical suicide attempt, and the absence of overt mania episodes (DSM-5, 2013).
While the patient exhibits hypomanic features since age 23, such as irritability and decreased need for sleep, these are less prominent or may have been underreported (Stahl Online, 2018). Confirming hypomanic episodes through collateral reports is essential before diagnosing Bipolar II. The absence of clear, sustained hypomanic episodes favors a diagnosis of complex major depression with anxious features.
Pharmacological Management
First-line pharmacotherapy typically involves mood stabilizers such as Lithium or Lamictal. Lithium remains the gold standard for bipolar disorder, especially for prevention of mood swings and suicidality (Stahl, 2017). However, Lithium carries risks of nephrotoxicity and requires ongoing renal function monitoring. Blood levels should be maintained within therapeutic ranges of 0.6–1.2 mEq/L, with frequent initial testing. Dosing adjustments based on renal function, age, and ethnicity are necessary; for example, research indicates that non-Caucasians may have lower oral clearance of Lamictal, requiring dose reductions (Prescribing Information, 2005).
Lamictal (lamotrigine) is an effective alternative with a favorable side effect profile. It requires slow titration over 4-6 weeks to minimize the risk of Stevens-Johnson Syndrome. Its mechanism stabilizes mood by inhibiting glutamate release and stabilizing neuronal excitability (Stahl, 2013). Dosing starts at 25 mg daily, gradually increasing to 200 mg/day. Patients should undergo liver function tests and monitor for rash.
Antipsychotics, both first and second generation, may be adjuncts for managing mood instability, agitation, or psychotic features. However, they pose risks for metabolic syndrome, necessitating periodic metabolic panels (Stahl, 2013). The combination of mood stabilizers and antipsychotics can be beneficial in treatment-resistant cases but necessitates vigilant monitoring.
Follow-up and Monitoring
Careful follow-up is vital for optimal outcomes. Initial follow-up should occur within 2-4 weeks to assess medication tolerability, side effects, and compliance. Subsequent visits every 3 months monitor laboratory parameters and symptom control. For example, in a 12-week follow-up, the patient might initiate lamotrigine at 25 mg daily, titrate up weekly, and adjust based on clinical response and side effects.
Monitoring the efficacy of treatment is essential; if medications induce depressive symptoms or fail to stabilize mood swings, alternative therapies or combination regimens should be considered. Serial assessments using scales like the Young Mania Rating Scale or Hamilton Depression Rating Scale objectively gauge response. Adjusting medication doses to maintain mood stabilization while minimizing adverse effects is a delicate balance.
Ethical and Clinical Considerations
Given the patient's status as a physician, ethical concerns include the potential for self-prescription and non-compliance. Close supervision, including involving family or colleagues, is advisable. Ethical practice mandates respecting the patient's autonomy while ensuring safety, especially considering the risk of suicidal behavior. Monitoring adherence and safeguarding against self-medication or medication misuse are critical components of ethical care.
Furthermore, mental health stigma and personal delays in seeking treatment often hinder recovery in similar cases. Providing psychoeducation, fostering trust, and involving multidisciplinary teams—psychologists, social workers, and primary care providers—enhance treatment adherence and outcomes.
Conclusion
Effectively managing complex mood disorders in challenging patients necessitates a comprehensive, multidisciplinary approach that combines accurate diagnosis, appropriate pharmacotherapy, vigilant monitoring, and ethical vigilance. Tailoring pharmacologic treatment based on individual patient profiles, including pharmacogenomic considerations, enhances efficacy and safety. As illustrated in this case, ongoing assessment, collaboration, and compassionate care are paramount to achieving long-term stability and improving the patient's quality of life.
