Mrs. C, age 56, has a history of major depressive disorder (MDD). She has been stable for 5 years without medication. Six months ago, she presented to you, along with her son, seeking help. She reported that she had been experiencing insomnia, fatigue, and was not engaging in hobbies. Her son told you that his mother had lost weight and had been avoiding family dinners. Mrs. C reported recurrent thoughts of dying and heard voices vividly telling her that she was a burden and that her family would be better off without her. However, there was no imminent danger of self-harm. At that appointment, you initiated sertraline, 50 mg/d titrated to 100 mg/d, and olanzapine, 5 mg/d.
Since that time, Mrs. C has followed up with you monthly with good response to the medications. Currently, she states her depression is much improved, and she denies hearing voices for approximately 5 months.
Based on her presentation and response, what do the data suggest about her length of treatment, and when should you consider tapering the antipsychotic medication?
In DSM-5, MDD with psychotic features is a severe subtype of MDD that is defined as a major depressive episode characterized by delusions and/or hallucinations.1 In the general population, the lifetime prevalence of this disorder varies from 0.35% to 1%, and the rate is higher in older patients.2 Risk factors include female gender, family history, and concomitant bipolar disorder.2
Epidemiologic studies have shown that psychotic features can occur in 15% to 20% of patients with MDD. The psychotic features that occur during these episodes are delusions and hallucinations.1 These features can be either mood-congruent (related to the depressive themes of worthlessness or guilt) or mood-incongruent (ie, unrelated to depressive themes).1
Treatment options: ECT or pharmacotherapy
Guidelines from the American Psychiatric Association3 and the National Institute for Clinical Excellence4 recommend treating depression with psychosis with electroconvulsive therapy (ECT) or with combined antidepressant and antipsychotic medications as first-line options. The Texas Medication Algorithm Project (TMAP) Algorithm for MDD,5 which closely focuses on treatment of MDD with psychotic features, can be used for treatment decisions (see Related Resources).
Electroconvulsive therapy is known to be efficacious in treating patients with MDD with psychotic features and should be considered as a treatment option. However, medication therapy is often chosen as the initial treatment due to the limitations of ECT, including accessibility, cost, and patient preference. However, in certain cases, ECT is the preferred option because it can provide rapid and significant improvement in patients with severe psychosis, suicidality, or risk of imminent harm.
