The Effect of Eye Movement Desensitization and Reprocessing (EMDR) on the severity of suicidal thoughts in patients with major depressive disorder: a randomized controlled trial

Randomized controlled trial investigating web-based, therapist delivered eye movement desensitization and reprocessing for adults with suicidal ideation

Introduction

Promising preliminary evidence suggests that EMDR may reduce suicidal ideation (SI) when used to treat Major Depressive Disorder, Posttraumatic Stress Disorder, and trauma symptoms in the context of acute mental health crises. EMDR has never been tested specifically for treating SI, and there is a lack of data regarding the safety and effectiveness of web-based, therapist-delivered EMDR in populations with known SI. The primary objective of this study was to investigate the impact of web-based, therapist-delivered EMDR, targeting experiences associated with suicidal thinking. Secondary objectives included examining the effect of EMDR treatment on symptoms of depression, anxiety, posttraumatic stress, emotional dysregulation, and dissociation, as well as safety and attrition.

Methods

This randomized control trial (ClinicalTrials.gov ID number: NCT04181047) assigned adult outpatients reporting SI to either a web-based EMDR intervention or a treatment as usual (TAU) group. TAU included primary and mental health services available within the Canadian public health system. Participants in the EMDR group received up to 12 web-based EMDR desensitization sessions, delivered twice weekly during the COVID-19 pandemic (2021-2023). The Health Research Ethics Board at the University of Alberta approved the protocol prior to initiation of data collection for this study (protocol ID number: Pro00090989).

Results

Forty-two adult outpatients received either EMDR (n=20) or TAU (n=22). Participants reported a high prevalence of early onset and chronic SI, and there was a high rate of psychiatric comorbidity. In the EMDR group, median SI, depression, anxiety, and posttraumatic symptom scale scores decreased from baseline to the four month follow-up. In the TAU group, only the median SI and posttraumatic symptom scale scores decreased from baseline to four month follow up. Although sample size precludes direct comparison, there were numerically fewer adverse events and fewer dropouts in the EMDR group relative to the TAU group.

Conclusion

Study results provide promising preliminary evidence that web-based EMDR may be a viable delivery approach to address SI. In this complex population, a short treatment course was associated with reductions of SI and other symptoms across multiple diagnostic categories. Further investigation is warranted to verify and extend these results.

2MDR, a Microcomputer-Controlled Visual Stimulation Device for Psychotherapy-Like Treatments of Mice

Post-traumatic stress disorder and other mental disorders can be treated by an established psychotherapy called Eye Movement Desensitization and Reprocessing (EMDR). In EMDR, patients are confronted with traumatic memories while they are stimulated with alternating bilateral stimuli (ABS). How ABS affects the brain and whether ABS could be adapted to different patients or mental disorders is unknown. Interestingly, ABS reduced conditioned fear in mice. Yet, an approach to systematically test complex visual stimuli and compare respective differences in emotional processing based on semiautomated/automated behavioral analysis is lacking. We developed 2MDR (MultiModal Visual Stimulation to Desensitize Rodents), a novel, open-source, low-cost, customizable device that can be integrated in and transistor-transistor logic (TTL) controlled by commercial rodent behavioral setups. 2MDR allows the design and precise steering of multimodal visual stimuli in the head direction of freely moving mice. Optimized videography allows semiautomatic analysis of rodent behavior during visual stimulation. Detailed building, integration, and treatment instructions along with open-source software provide easy access for inexperienced users. Using 2MDR, we confirmed that EMDR-like ABS persistently improves fear extinction in mice and showed for the first time that ABS-mediated anxiolytic effects strongly depend on physical stimulus properties such as ABS brightness. 2MDR not only enables researchers to interfere with mouse behavior in an EMDR-like setting, but also demonstrates that visual stimuli can be used as a noninvasive brain stimulation to differentially alter emotional processing in mice.

Eye movement desensitization and reprocessing as a therapy for rape victims: A case series

A case series was conducted on three rape victims who were hospitalized with a diagnosis of major depressive disorder (MDD). Eye movement desensitization and reprocessing (EMDR) was employed to reduce their risk of suicide or suicidal ideations. EMDR can be an effective treatment to reduce the level of suicidal ideation in rape victims.

Web-Based Eye Movement Desensitization and Reprocessing for Adults With Suicidal Ideation: Protocol for a Randomized Controlled Trial

BACKGROUND

Adversity and traumatic experiences increase the likelihood of suicidal thoughts and behaviors. Eye Movement Desensitization and Reprocessing (EMDR) is an evidence-based, trauma-focused psychotherapy that desensitizes painful memories, so that reminders in the present no longer provoke overwhelming emotional responses. Preliminary evidence suggests that EMDR can be used as an acute intervention in suicidal patients, including those with major depressive disorder. In addition, because of social distancing restrictions during the COVID-19 pandemic, clinicians have been using EMDR on the web and, in the absence of formal evaluations of web-based EMDR, informal reports indicate good results.

OBJECTIVE

The primary aim of this randomized controlled trial is to investigate whether remotely delivered EMDR (targeting experiences associated with suicidal thinking) reduces suicidal thoughts. Secondary aims include examining the impact of remotely delivered EMDR on symptoms of depression, anxiety, posttraumatic stress, emotional dysregulation, and dissociation. We will also report on adverse events in the EMDR group to explore whether targeting suicidal ideation with EMDR is safe. Finally, we will compare dropout rates between the treatment groups.

METHODS

In this randomized controlled trial, 80 adults who express suicidal ideation and meet the study criteria will receive either 12 sessions of twice weekly EMDR plus treatment as usual or treatment as usual alone. EMDR sessions will focus on the most distressing and intrusive memories associated with suicidal ideation. Data for primary and secondary objectives will be collected at baseline, 2 months, and 4 months after enrollment. A subsequent longer-term analysis, beyond the scope of this protocol, will examine differences between the groups with respect to the number of posttreatment emergency room visits, hospitalizations, and overall health care use in the year before and after therapy.

RESULTS

The protocol was approved by the University of Alberta Research Health Ethics Board (protocol ID Pro00090989). Funding for this study was provided by the Mental Health Foundation (grant RES0048906). Recruitment started in May 2021, with a projected completion date of March 2023.

CONCLUSIONS

The results of this trial will contribute to knowledge on whether web-based delivery of EMDR is a safe and effective treatment for reducing suicidal ideation and potentially reducing the incidence of suicide attempts in this patient population.

EMDR as Treatment Option for Conditions Other Than PTSD: A Systematic Review

Eye Movement Desensitisation and Reprocessing (EMDR) is a treatment for post-traumatic stress disorder (PTSD). The technique is known to facilitate reprocessing of maladaptive memories that are thought to be central to this pathology. Here we investigate if EMDR therapy can be used in other conditions. We conducted a systematic literature search on PubMed, ScienceDirect, Scopus, and Web of Science. We searched for published empirical findings on EMDR, excluding those centred on trauma and PTSD, published up to 2020. The results were classified by psychiatric categories. Ninety articles met our research criteria. A positive effect was reported in numerous pathological situations, namely in addictions, somatoform disorders, sexual dysfunction, eating disorders, disorders of adult personality, mood disorders, reaction to severe stress, anxiety disorders, performance anxiety, Obsessive-Compulsive Disorder (OCD), pain, neurodegenerative disorders, mental disorders of childhood and adolescence, and sleep. Some studies reported that EMDR was successful in usually uncooperative (e.g., Dementia) or unproductive cases (e.g., aphasia). Moreover, in some severe medical conditions, when psychological distress was an obstacle, EMDR allowed the continuation of treatment-as-usual. Furthermore, the effects observed in non-pathological situations invite for translational research. Despite a generally positive outlook of EMDR as an alternative treatment option, more methodologically rigorous studies are needed. We discuss the advantages and limitations and possible implications for the hypothesised mechanisms of action.

The potential role of EMDR on trauma in affective disorders: A narrative review

BACKGROUND

Eye Movement Desensitization and Reprocessing (EMDR) is a psychotherapeutic approach that has originally been developed to treat post-traumatic stress disorder (PTSD). Recently it has been suggested as a complementary therapy in a wide range of clinical conditions. In particular, affective disorders as bipolar disorder (BD) and major depressive disorder (MDD) have a higher lifetime prevalence of traumatic or stressful life events (SLEs) compared to the general population, which makes them good candidates for the application of EMDR.

METHODS

A bibliographic search on PUBMED, Scopus, and ScienceDirect of studies applying EMDR to people with a primary diagnosis of bipolar disorder (BD) and major depressive disorder (MDD) (with or without a comorbid PTSD) was conducted.

RESULTS

Literature search retrieved 15 studies, of which 3 were focused on BD and 12 on MDD. Overall, they suggest EMDR as an effective tool in reducing trauma-related but also manic and depressive symptoms, with few effect sides and high adherence rates.

LIMITATIONS

Few small studies exist with heterogeneous and not gold-standard methodology, especially for BD.

CONCLUSIONS

Overall, retrieved studies can be considered as first attempts at investigating the applicability of EMDR in affective disorders. Although far to be conclusive, preliminary evidence suggests EMDR as a useful adjunctive approach in the treatment of BD and MDD, especially when other treatments have failed. It is now the time to implement such trauma-focused therapy to larger samples of patients using more rigorous methods.

Efficacy of Eye Movement Desensitization and Reprocessing on the Quality of Life in Patients with Major Depressive Disorder: A Randomized Clinical Trial

Introduction

The present study was conducted with the aim of investigating the efficacy of eye movement desensitization and reprocessing (EMDR) on the quality of life (QOL) in patients with major depressive disorder (MDD).

Methods

This is a randomized clinical trial study that investigated the efficacy of EMDR on the QOL in patients with MDD. In this study, all patients suffered from psychological trauma were currently in a major depressive episode and had a history of depression. 70 patients with MDD were selected through convenience sampling. Patients were then assigned to two groups of intervention and control (35 patients in each group). The assignment was performed randomly. For the intervention group, EMDR were performed in eight 90 mins sessions over 3 weeks. For the control group, no intervention was considered. Data on the QOL were collected using the WHO Quality of Life-BREF instrument before and after the treatment, and analysed using descriptive tests, paired t-test, independent t-test, and chi-square with SPSS v19.

Results

This study showed that the QOL in all its domains (physical health, psychological health, social relationships and environments) was significantly improved in patients with MDD in the intervention group after 8 sessions of EMDR. The post-treatment effect for the EMDR condition was 2.11, with a confidence interval of 1.3 to 2.7. Another finding of this study was that there was a statistically significant difference in the QOL scores in patients in the control group before and after the treatment; however, the mean difference in the intervention group was more than the control.

Conclusion

The results of this study showed that EMDR were effective on the QOL in patients with major depressive disorder, and improved individuals' QOL and all its domains. Treatment team members may use this technique as an effective and supportive one to improve the QOL in patients.

Using EMDR therapy with patients in an acute mental health crisis

BACKGROUND

Death by suicide continues to be a global public health concern with little research demonstrating the effectiveness of treatment options. This exploratory study exams the efficacy of Eye Movement Desensitisation and Reprocessing (EMDR) Therapy delivered to patients experiencing an acute mental health crisis to explore if by treating their background trauma, improvements could be seen in their general psychopathology and if there was a resulting decrease in their desire for suicide.

METHODS

A practice-based service development project was conducted within a mental health hospital. A non-randomised, exploratory pre-test post-test design was utilised. Participants were identified from adult patients currently receiving care from either an inpatient mental health ward or the Crisis Resolution and Home Treatment Team (CRHTT). Those who had reported experiencing at least one event that they considered to be traumatic were offered EMDR Therapy. Notes from the electronic database were analysed to assess contact with services 12 months prior to treatment and following treatment.

RESULTS

72 patients were offered treatment in the study with 57 completing treatment. Patients made significant improvements across all the psychometrics, including a reduction in suicidal ideation. The majority needed less than 10 sessions and needed no onward referral for further psychological therapy. Cost savings were realised by retracting referrals for further therapy and in early discharge from CRHTT and acute wards, and by preventing admissions. Contact with services post treatment also reduced.

CONCLUSIONS

EMDR Therapy can be an effective treatment for patients experiencing a mental health crisis who have a trauma picture, resulting in significant improvements in their mental well-being and substantial cost savings for the National Health Service (NHS).
