In this podcast, the underreporting of psychotic symptoms in depression is discussed, along with the higher suicide rate in individuals with psychotic depression. The use of acceptance and commitment therapy (ACT) and antipsychotics for treatment is explored. The differences between nightmares in PTSD and malingering are examined. The complexities of treating psychotic depression and alternative approaches, such as ECT and ketamine, are discussed. The mechanisms and diagnosis of depression and delirium are explained. The importance of identifying and treating UTIs in elderly patients to prevent delirium is emphasized. The speaker's approach to assessing patients for medical issues is outlined. The potential differential diagnoses for psychotic depression, including substance use disorder and borderline personality disorder, are explored. The Bush-Francis-Catatonia Scale and treatment with lorazepam are discussed. The process of administering intramuscular medication for psychotic depression is explained.
The underreporting of psychotic symptoms in individuals with depression is a significant concern, driven by fear of consequences and stigma.
Psychotic depression has a higher suicide rate compared to non-psychotic depression, with most suicides occurring within the first two years following diagnosis.
Psychotic depression requires a combination of antidepressant and antipsychotic medications for effective treatment, with electroconvulsive therapy (ECT) considered for severe cases.
Deep dives
History and differential diagnosis of psychotic depression
Psychotic depression has a complex history, with the definition and understanding evolving over time. Previously, psychotic depression referred to severe cases where individuals were unable to carry out daily activities. However, the current understanding recognizes that psychosis can occur in mild, moderate, or severe depression. Differential diagnosis is crucial to differentiate psychotic depression from conditions like borderline personality disorder, delirium, bipolar disorder, and substance-induced psychosis.
Types of psychotic symptoms in depression
Psychotic symptoms in depression can be categorized as either mood congruent or mood incongruent. Mood congruent symptoms include personal inadequacy, guilt, nihilistic beliefs, and self-punishment ideation. Mood incongruent symptoms, on the other hand, involve delusions or hallucinations that are not consistent with the depressive mood, such as grandiose or paranoid beliefs. The presence of mood incongruent symptoms may indicate a potential bipolar disorder, especially if coupled with other clinical indicators.
Treatment considerations for psychotic depression
Psychotic depression often requires a combination of antidepressant and antipsychotic medications for effective treatment. However, antidepressants alone may have limited efficacy in treating the psychotic symptoms. Electroconvulsive therapy (ECT) is considered for severe cases that do not respond to medication. Other treatment options include acceptance and commitment therapy (ACT) and psychotherapy to build a therapeutic alliance and address underlying issues. Lifestyle changes, such as exercise and diet, may also be beneficial, although compliance can be challenging as the severity of depression increases.
Treatment approach for psychotic depression
In the treatment of psychotic depression, the first-line approach would typically involve a combination of an SSRI antidepressant and a second-generation antipsychotic. If there is no response or the patient's condition worsens, electroconvulsive therapy (ECT) may be recommended. Hospitalized patients who have failed an adequate trial of antidepressant/antipsychotic treatment may proceed rapidly to ECT. Outpatient individuals may be given multiple trials of medications before considering ECT. Overall, the severity of the depression and the presence of psychosis are key factors in determining the treatment approach.
Understanding the mechanism and brain changes
Depression, including psychotic depression, is associated with significant changes in the brain. Studies have shown a decline in glucose uptake and utilization, loss of dendritic arborization, and reduced metabolic rates in frontal temporal areas. These changes in brain structure and function can contribute to the development of psychosis in some cases. Additionally, brain derived neurotrophic factor (BDNF) levels are significantly decreased in major depressive disorder, but can be increased with various treatment modalities, including medication, therapy, and exercise. The understanding of the biological underpinnings of depression has evolved from a focus on chemical imbalances to a recognition of broader brain changes and dysregulation in mood and brain connectivity.
The underreporting of psychotic symptoms by patients in depression is a significant concern, frequently driven by the fear of consequences like hospitalization or the stigma of embarrassment.
We'll discuss the history, the differential to consider when thinking of psychotic depression, mechanisms, and treatment. Notably, individuals with psychotic depression face a suicide rate double that of their non-psychotic counterparts. A recent cohort study by Paljärvi in 2023 revealed a stark contrast: deaths due to suicide were 2.6% in the psychotic depression cohort, compared to 1% in the non-psychotic group. Alarmingly, most suicides occurred within the first two years following diagnosis. People who suffer from psychotic depression often do not report their psychotic symptoms, leading to inadequate response to normal depression treatments. With 6-25% of individuals with major depressive disorder (MDD) exhibiting psychotic features, it is imperative to understand and address these unique challenges. Join us as we unravel the complexities of this underrecognized aspect of mental health.
