Does prior traumatization affect the treatment outcome of CBT for panic disorder? The potential role of the MAOA gene and depression symptoms

Trauma history and course of therapy in a naturalistic cognitive behavior therapy outpatient sample: An archive data study

OBJECTIVE

Cognitive Behavior Therapy (CBT) is an effective treatment for anxiety and depression disorders. Nonetheless, nearly 50% of all patients do not respond. Besides other factors, nonresponse may be linked to traumatic life events. This study aims to assess the relationship between trauma history, applied therapy interventions, and therapy outcomes.

METHODS

We analyzed data from 340 CBT outpatients diagnosed with a depression or anxiety disorder and possibly a trauma history treated under naturalistic conditions. Based on their therapy files, we collected information on trauma history, diagnoses, applied interventions, and severity of depression and anxiety symptoms at the start and end of therapy. The relationship between trauma, diagnoses, and intervention use and the development of depression and anxiety symptoms was analyzed using Linear Mixed Models.

RESULTS

Patients with a trauma history reported higher pre- and posttreatment symptom severity than those without trauma. No differences in applied interventions or decrease in symptom severity were found between patients with and without a trauma history. Specialized interventions were seldom applied.

CONCLUSION

Although no differences between patients with and without a trauma history were found in therapy response, patients with a trauma history maintained higher levels of symptom severity. These results indicate a need for more personalized interventions and evidence-based guidelines to personalize CBT for patients with a trauma history and high symptom severity.

History of Sexual Assault as a Predictor of Response to a Self-Guided Online Program for Sexual Desire and Arousal Difficulties in Women

Sexual Interest/Arousal Disorder (distressing, long-lasting impairments in sexual desire and/or arousal) is common in women, but few have access to efficacious psychotherapies, including cognitive-behavioral therapy (CBT) and mindfulness-based therapy (MBT). eSense, an online program meant to maximize treatment access, has been shown to be a feasible, satisfactory, and potentially efficacious intervention. However, subpopulations such as sexual assault survivors may find the program less usable or efficacious. The current study compared women with and without a history of sexual assault (SA) regarding their ability to use and benefit from eSense. Forty-four women (22 with a history of SA; M age = 34.20 years) used eSense (CBT or MBT) and completed validated self-report scales of sexual function, sexual distress, treatment satisfaction, and homework compliance. A history of SA did not predict differences in attrition or changes in clinical outcomes. Exploratory analyses suggested that women with a history of SA reported slightly higher difficulty completing homework assignments, but also slightly higher treatment satisfaction. These preliminary results suggest that eSense may be usable and helpful for women with a history of SA. We discuss ways to maximize the acceptability and efficacy of online programs for women with a history of SA.

The Relationship Between 5-Hydroxytryptamine and Its Metabolite Changes With Post-stroke Depression

Post-stroke depression (PSD) is the most common and serious sequelae of stroke. Approximately 33% of stroke survivors were affected by PSD. However, many issues (e.g., incidence, diagnostic marker, and risk factor) related to PSD remained unclear. The "monoamine hypothesis" is a significant hypothesis for depression, which suggests that three monoamines play a key role in depression. Therefore, most current antidepressants are developed to modulate the monoamines on PSD treatment, and these antidepressants have good effects on patients with PSD. However, the potential mechanisms of three monoamines in PSD are still unclear. Previously, we proposed "three primary emotions," which suggested a new model of basic emotions based on the three monoamines. It may provide a new way for PSD treatment. In addition, recent studies have found that monoamine-related emotional intervention also showed potential effects in the treatment and prevention of PSD. This study discusses these issues and attempts to provide a prospect for future research on PSD.

Imaging and Genetic Approaches to Inform Biomarkers for Anxiety Disorders, Obsessive-Compulsive Disorders, and PSTD

Anxiety disorders are the most common mental health problem in the world and also claim the highest health care cost among various neuropsychiatric disorders. Anxiety disorders have a chronic and recurrent course and cause significantly negative impacts on patients' social, personal, and occupational functioning as well as quality of life. Despite their high prevalence rates, anxiety disorders have often been under-diagnosed or misdiagnosed, and consequently under-treated. Even with the correct diagnosis, anxiety disorders are known to be difficult to treat successfully. In order to implement better strategies in diagnosis, prognosis, treatment decision, and early prevention for anxiety disorders, tremendous efforts have been put into studies using genetic and neuroimaging techniques to advance our understandings of the underlying biological mechanisms. In addition to anxiety disorders including panic disorder, generalised anxiety disorder (GAD), specific phobias, social anxiety disorders (SAD), due to overlapping symptom dimensions, obsessive-compulsive disorder (OCD), and post-traumatic stress disorder (PTSD) (which were removed from the anxiety disorder category in DSM-5 to become separate categories) are also included for review of relevant genetic and neuroimaging findings. Although the number of genetic or neuroimaging studies focusing on anxiety disorders is relatively small compare to other psychiatric disorders such as psychotic disorders or mood disorders, various structural abnormalities in the grey or white matter, functional alterations of activity during resting-state or task conditions, molecular changes of neurotransmitter receptors or transporters, and genetic associations have all been reported. With continuing effort, further genetic and neuroimaging research may potentially lead to clinically useful biomarkers for the prevention, diagnosis, and management of these disorders.
