Today, I'm writing from the cutting-edge of innovation and enquiry in PTSD. PTSD science continues to advance exponentially, and heady breakthroughs are on the horizon. What I'm presenting in this mail are some of the highlights from the last two years of scientific findings.

While these approaches can't all the same be considered the gold standard for PTSD treatment, what they correspond is hope for an always-expanding array of options that might be available for sufferers one day.

I've divided the treatments into three categories: psychotropic medications, procedures, and non-pharmacological approaches.

Psychotropic Medications

MDMA-Assisted Psychotherapy

May 2021 heralded promising results from the first phase 3 clinical trial testing MDMA-assisted psychotherapy for the treatment of PTSD. In MDMA-assisted therapy, the medication MDMA is only administered a few times, and the talk therapy component remains an integral part of this combination treatment.

In an article published in Nature Medicine, researchers from UCSF reported on results of their trial, which sought to test the efficacy and safety of MDMA-assisted therapy for the treatment of 90 patients with severe PTSD over 15 clinical sites. The results were impressive, with patients reporting a large drop in symptoms after receiving MDMA-assisted therapy.

Of particular interest was that the study included patients with common PTSD comorbidities such as dissociation, depression, a history of alcohol and substance employ disorders, and childhood trauma. In this fashion, the study atmospheric condition improve mimicked real-earth clinical scenarios and therefore gave crusade to be optimistic that such a handling may eventually provide tangible do good to patients treated in clinical practice.

Another plus for this research is that, for the duration of this report, the researchers reported that MDMA did not induce adverse events such as corruption potential or suicidality. Furthermore, unlike most medications for mental illnesses which are oftentimes taken daily for a substantial length of time, MDMA is only taken a few times.

A second stage 3 trial is currently underway and, if results continue to be encouraging, a drug awarding with the FDA is anticipated in 2022.

Repeated Ketamine Infusions

Ketamine is a non-barbiturate anesthetic and antagonist at the NMDA receptor. It is typically administered intravenously and has been used for years to provide pain relief to patients with severe burns. It was in this use that its dissociative backdrop became apparent. Ketamine may disrupt the process by which traumatic memories are laid down, as some studies show that those who received ketamine after a traumatic result were less likely to go on to develop PTSD.

In a 2021 study published in the American Journal of Psychiatry (in Accelerate), researchers from Icahn School of Medicine at Mount Sinai suggested that repeated ketamine infusions may lead to rapid symptom improvement in people with PTSD.

30 study participants who received six ketamine infusions over a two-week catamenia experienced greater drops in PTSD symptoms and comorbid depressive symptoms compared with participants who received the sedative midazolam, a psychoactive placebo control administered approximately three times a week for two weeks.

Side effects associated with the ketamine included blurred vision, dizziness, fatigue, and headache. Of more business concern is that some participants did report dissociative symptoms that emerged during their ketamine infusions.

It'southward important to note the limitations associated with ketamine: Benefits may last simply a few weeks and in that location is a potential for patients getting fond to this treatment.

Riluzole: A Glutamatergic Modulator

In a 2020 report published in the Journal of Clinical Psychiatry, researchers designed a randomized controlled trial that investigated the efficacy of Riluzole augmentation for gainsay-related PTSD symptoms resistant to treatment with selective serotonin reuptake inhibitors (SSRIs) or serotonin-norepinephrine reuptake inhibitors (SNRIs).

Postal service-Traumatic Stress Disorder Essential Reads

Riluzole is a neuroprotective drug that blocks glutamatergic neurotransmission in the CNS. Glutamate dysregulation has been implicated in the pathophysiology of PTSD, so medications that regulate encephalon glutamate concentrations may be an effective treatment strategy for PTSD.

Over a four-yr period, veterans and agile duty service members with gainsay-related PTSD who were non responsive to SSRI or SNRI pharmacotherapy were randomized to 8-calendar week augmentation with a starting dose of 100 mg/day of riluzole or placebo.

An analysis of PTSD symptom clusters showed significantly greater improvement on PTSD hyperarousal symptoms in the riluzole group. However, Riluzole augmentation was non superior to placebo on change in low, anxiety, or disability severity.

Procedures

Stellate Ganglion Block Treatment

In 2008, media reports started to emerge nearly how a stellate ganglion block (SGB), an invasive manipulation of sympathetic nerve tissue, helped PTSD sufferers. The procedure, which consisted of injecting a local anesthetic into sympathetic nerve tissue in the neck, led to immediate symptom relief in a small group of patients.

Nevertheless, a positive outcome in a few cases is non sufficient to label something a handling. A handling should exist more than effective than a placebo, and so information technology needs to exist studied under controlled weather. Information technology took some time for the first controlled study of the SGB to exist done, and the initial results, which were reported in 2016, were disappointing: The block was not superior to sham injection in relieving PTSD.

In early 2020, results of the outset multisite, randomized clinical trial of (SGB) outcomes on PTSD symptoms were published in the Journal of the American Medical Clan - Psychiatry and revealed reasons to non requite upwardly on SGB entirely. In this trial of active-duty service members with PTSD symptoms, the authors reported that 2 SGB treatments two weeks apart were constructive in reducing PTSD scores over a period of eight weeks.

The written report was limited by the fact that the service members had mild-moderate baseline level of PTSD symptom severity to brainstorm with and the short follow-up fourth dimension of but eight weeks ways dubiety about how long the benefits of SGB might terminal. Still, these more than contempo and encouraging results suggest that SGB merits further investigation and may well prove to earn a place equally an adjunct handling for PTSD.

Theta Outburst Stimulation (TBS) — A Novel Form of Repetitive Transcranial Magnetic Stimulation

In a 2020 study published in Armed services Medicine, Australian researchers from the Middle for Post-traumatic Mental Health reported on results of a pilot study that used Theta Flare-up Stimulation (TBS), a novel form of Repetitive Transcranial Magnetic Stimulation shown to improve depressive disorders in Australian veterans with PTSD.

In a case series, eight Australian Defense Force veterans with PTSD received 20 bilateral TBS treatments over a four-week catamenia. Participants exhibited reductions in both PTSD and depression symptoms, equally well every bit improvements in working retentivity and processing speed. Furthermore, the procedure was well tolerated, with no serious side effects or agin events reported.

While these early results are encouraging, the limitations of this study design hateful that large-scale, randomized controlled trials are warranted before this potential arroyo could be considered a mainstream handling option.

Non-Pharmacological Approaches

Meditation-Based Interventions

In a 2021 article published in Advances in Listen-Body Medicine, authors Haider and Sharma reviewed the extant literature on how constructive meditation-based interventions are for the treatment of PTSD. They reported how, in randomized controlled trials, interventions such as transcendental meditation, mantra meditation, mindful meditation, animate-based meditation, and mindfulness-based exposure showed improvements in PTSD symptoms.

That said, bug with the quality of some of these studies remain. Until more data is available, meditation-based therapy remains a valuable adjunct or add-on treatment to more than established PTSD treatments, but non a recommended stand-alone treatment.

Certified Peer Specialists equally Office of the Treatment Team

In a 2020 commodity published in the Journal of Clinical Psychology, researchers at Boston Medical Center used a mixed methods approach to investigate if PTSD treatment delivery by peer specialist providers could increment access to and date with PTSD treatment in low-resources settings.

In this airplane pilot study they tested the feasibility, acceptability, and initial effectiveness of a brief cognitive-behavioral therapy for PTSD delivered by four certified peer specialists to 18 clients. Data from this preliminary study propose the intervention was feasible and associated with high client satisfaction.

Participants in the report showed significant improvements in PTSD, depressive, feet, and general stress symptoms. This research offers hope for combatting the troubling issue of many PTSD sufferers lacking admission to mental healthcare, peculiarly those living in rural, remote, and inner-urban center areas. The prospect of beingness able to increase access to skillful quality PTSD care by leveraging the power of peers is exciting.

This post highlights new and emerging potentials for treating PTSD and trauma-related stress disorders. For now, however, these treatments remain largely experimental and in need of further investigation.
