Cannabis-assisted psychotherapy for complex dissociative posttraumatic stress disorder: A case report. Front Psychiatry 2023; 14:1051542. [PMID: 36846226 PMCID: PMC9947284 DOI: 10.3389/fpsyt.2023.1051542] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/22/2022] [Accepted: 01/23/2023] [Indexed: 02/11/2023] Open
Abstract
BACKGROUND A dissociative subtype of posttraumatic stress disorder, known as "D-PTSD", has been included in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition. In addition to meeting criteria for PTSD, patients endorse prominent dissociative symptoms, namely depersonalization and derealization, or detachment from one's self and surroundings. At present, this population is supported by a highly heterogeneous and undeveloped literature. Targeted interventions are therefore lacking, and those indicated for PTSD are limited by poor efficacy, delayed onset of action, and low patient engagement. Here, we introduce cannabis-assisted psychotherapy (CAP) as a novel treatment for D-PTSD, drawing parallels to psychedelic therapy. CASE PRESENTATION A 28-year-old female presented with complex D-PTSD. In a naturalistic setting, she underwent 10 sessions of CAP, scheduled twice monthly over 5 months, coupled with integrative cognitive behavioral therapy. An autonomic and relational approach to CAP was leveraged, specifically psychedelic somatic interactional psychotherapy. Acute effects included oceanic boundlessness, ego dissolution, and emotional breakthrough. From baseline to post-treatment, the patient showed a 98.5% reduction in pathological dissociation, as measured by the Multidimensional Inventory of Dissociation, no longer meeting criteria for D-PTSD. This was accompanied by decreased cognitive distractibility and emotional suffering, as well as increased psychosocial functioning. Anecdotally, the patient has sustained improvements for over 2 years to date. CONCLUSIONS There is urgency to identify treatments for D-PTSD. The present case, while inherently limited, underscores the potential of CAP as a therapeutic option, leading to robust and sustained improvement. Subjective effects were comparable to those produced by classic and non-classic psychedelics, such as psilocybin and ketamine. Further research is warranted to explore, establish, and optimize CAP in D-PTSD, and to characterize its role in the pharmacological landscape.

Abstract
Introduction Existing reviews exploring cannabis effectiveness have numerous limitations including narrow search strategies. We systematically explored cannabis effects on PTSD symptoms, quality of life (QOL), and return to work (RTW). We also investigated harm outcomes such as adverse effects and dropouts due to adverse effects, inefficacy, and all-cause dropout rates. Methods Our search in MEDLINE, EMBASE, PsycInfo, CINAHL, Web of Science, CENTRAL, and PubMed databases, yielded 1 eligible RCT and 10 observational studies (n = 4672). Risk of bias (RoB) was assessed with the Cochrane risk of bias tool and ROBINS-I. Results Evidence from the included studies was mainly based on non-randomized studies with no comparators. Results from unpooled, high RoB studies showed that cannabis was associated with a reduction in overall PTSD symptoms and improved QOL. Dry mouth, headaches, and psychoactive effects such as agitation and euphoria were the commonly reported adverse effects. In most studies, cannabis was well tolerated, but small proportions of patients experienced a worsening of PTSD symptoms. Conclusion Evidence in the current study primarily stems from low quality and high RoB observational studies. Further RCTs investigating cannabis effects on PTSD treatment should be conducted with larger sample sizes and explore a broader range of patient-important outcomes.

Abstract
Epigenetic gene-regulation abnormalities have been implicated in various neuropsychiatric disorders including schizophrenia and depression, as well as in the regulation of mood and anxiety. In addition, epigenetic mechanisms are involved in the actions of psychiatric drugs. Current anxiolytic drugs have significant shortcomings, and development of new medications is warranted. Two proteins, G9a (also known as EHMT2 or KMT1C) and GLP (G9a-like protein, also known as EHMT1 or KMT1D), which methylate lysine 9 of histone H3 (H3K9), could be promising anxiolytic targets. Postnatal genetic knock-out of G9a reduces anxiety-related behavior, consistent with the reduction of G9a levels by some medications used to treat anxiety (amitriptyline, imipramine and paroxetine). Conversely, there is increased anxiety-like behavior in mice with GLP haplodeficiency. We sought to determine whether two pharmacological inhibitors of G9a/GLP, UNC0642 and A-366, would have similar effects to genetic G9a/GLP insufficiency. We found that G9a/GLP inhibition with either compound reduced anxiety-like behaviors when administered to adult mice, in conjunction with decreased H3K9 methylation in the brain. In contrast, exposure to these compounds from embryonic day 9.5 (E9.5) until birth increased anxiety-like behaviors and decreased social interaction in adulthood, while H3K9 methylation was at normal levels in the brains of the adult mice. These findings reinforce genetic evidence that G9a/GLP has different effects on anxiety-like behavior at different stages of brain development, and suggest that targeting this histone methyltransferase pathway could be useful for developing new anxiolytic drugs. These data also suggest that antidepressant exposure in utero could have negative effects in adulthood, and further investigation of these effects is warranted.

Abstract
Background Over 1100 Veterans work in the Veterans Health Administration (VHA) as peer specialists (PSs). PSs are Veterans with formal training who provide support to other Veterans with similar diagnoses, primarily in mental health settings. A White House Executive Action mandated the pilot reassignment of VHA PSs from mental health to 25 primary care Patient Aligned Care Teams (PACT) in order to broaden the provision of wellness services that can address many chronic illnesses. An evaluation of this initiative was undertaken to assess the impact of outside assistance on the deployment of PS in PACT, as implementation support is often needed to prevent challenges commonly experienced when first deploying PSs in VHA settings. We present the protocol for this cluster-randomized hybrid type II trial to test the impact of standard implementation (receive minimal assistance) vs. facilitated implementation (receive outside assistance) on the deployment of VHA PSs in PACT. Methods A VHA Office of Mental Health Services work group is recruiting 25 Veterans Affairs Medical Centers to reassign a mental health PSs to provide wellness-oriented care in PACT. Sites in three successive cohorts (n = 8, 8, 9) beginning over 6-month blocks will be matched and randomized to either standard or facilitated implementation. In facilitated implementation, an outside expert works with site stakeholders through a site visit, regular calls, and performance data to guide the planning and address challenges. Standard implementation sites will receive a webinar and access the Office of Mental Health Services work group. The two conditions will be compared on PS workload data, fidelity to the PS model of service delivery, team functioning, and Veteran measures of activation, satisfaction, and functioning. Qualitative interviews will collect information on implementation barriers and facilitators. Discussion This evaluation will provide critical data to guide administrators and VHA policy makers on future deployment of PSs, as their role has been expanding beyond mental health. In addition, development of novel implementation strategies (facilitation tailored to PSs) and the use of new tools (peer fidelity) can be models for monitoring and supporting deployment of PSs throughout VHA.

Abstract
Post-traumatic stress disorder (PTSD) is a serious mental illness of considerable importance from a public health perspective. Management of PTSD may involve the use of various treatment modalities, involving both nondrug treatments and pharmacotherapy. Nondrug treatment is regarded as the first-line option for PTSD and should be routinely incorporated into management plans for patients with PTSD. However, some patients do not achieve a sufficient response to nondrug therapy or are left with disabling residual symptoms in one or more areas. Antidepressants are currently the preferred medication for PTSD, with the most substantial evidence available to support the use of the selective serotonin reuptake inhibitors. Many patients with PTSD have symptoms that are resistant to initial drug treatment, meaning that it is often necessary to explore additional pharmacotherapy options to achieve optimal symptom control: antipsychotics, anti-adrenergic drugs, anxiolytics and anticonvulsants have all been advocated as treatments for PTSD. In addition to the management of core PTSD symptoms, it is also necessary for clinicians to address important associated comorbidities, most notably, substance-use disorders and mood disturbances. Interpretation of research studies of the efficacy and safety of PTSD pharmacotherapy is often difficult owing to methodological limitations and factors such as inclusion bias. Further research in fundamental neurosciences and pharmacogenomics may help to elucidate optimal pharmacotherapy options for PTSD in the future.

Abstract
Posttraumatic stress disorder (PTSD) is common in primary care but it is frequently not detected or treated adequately. There is insufficient evidence to recommend universal screening for PTSD in primary care, but clinicians should remain alert to PTSD among patients exposed to trauma, and among those with other psychiatric disorders, irritable bowel syndrome, multiple somatic symptoms and chronic pain. A two-stage process of screening (involving the PC-PTSD), and, for those with a positive screen, a diagnostic evaluation (using the PTSD-Checklist), can detect most patients with PTSD with few false positives. Evidence-based recommendations are provided for treatment in primary care or referral to mental health.

Abstract
Post-traumatic stress disorder (PTSD) is a common and chronic anxiety disorder that can result after exposure to a traumatic event. Though our understanding of the aetiology of PTSD is incomplete, several neurobiological systems have been implicated in the pathophysiology and vulnerability towards developing PTSD after trauma exposure. We aimed to provide a concise review of benchmark findings in important neurobiological systems related to the aetiology and maintenance of PTSD symptomology. Specifically, we discuss functional aetiologies in the noradrenergic, serotonergic, endogenous cannabinoid and opioid systems as well as the hypothalamic-pituitary adrenal (HPA) axis. This article provides a succinct framework to appreciate the current understanding of neurobiological mechanisms related to the pathophysiology of PTSD and how these findings may impact the development of future, targeted pharmacological treatments for this debilitating disorder.

Abstract
BACKGROUND The prevention of long-term psychological distress following traumatic events is a major concern. Systematic reviews have suggested that individual Psychological Debriefing is not an effective intervention at preventing post traumatic stress disorder (PTSD). Recently other forms of intervention have been developed with the aim of preventing PTSD. OBJECTIVES To examine the efficacy of multiple session early psychological interventions commenced within three months of a traumatic event aimed at preventing PTSD. Single session individual/group psychological interventions were excluded. SEARCH STRATEGY Computerised databases were searched systematically, the most recent search was conducted in August 2008. The Journal of Traumatic Stress and the Journal of Consulting and Clinical Psychology were handsearched for the last two years. Personal communication was undertaken with key experts in the field. SELECTION CRITERIA Randomised controlled trials of any multiple session early psychological intervention or treatment (two or more sessions) designed to prevent symptoms of PTSD. DATA COLLECTION AND ANALYSIS Data were entered using Review Manager software. The methodological quality of included studies was assessed individually by two review authors. Data were analysed for summary effects using Review Manager 4.2. Mean difference was used for meta-analysis of continuous outcomes and relative risk for dichotomous outcomes. MAIN RESULTS Eleven studies with a total of 941 participants were found to have evaluated brief psychological interventions aimed at preventing PTSD in individuals exposed to a specific traumatic event, examining a heterogeneous range of interventions. Eight studies were entered into meta-analysis. There was no observable difference between treatment and control conditions on primary outcome measures for these interventions at initial outcome (k=5, n=479; RR 0.84; 95% CI 0.60 to 1.17). There was a trend for increased self-report of PTSD symptoms at 3 to 6 month follow-up in those who received an intervention (k=4, n=292; SMD 0.23; 95% CI 0.00 to 0.46). Two studies compared a memory structuring intervention against supportive listening. There was no evidence supporting the efficacy of this intervention. AUTHORS' CONCLUSIONS The results suggest that no psychological intervention can be recommended for routine use following traumatic events and that multiple session interventions, like single session interventions, may have an adverse effect on some individuals. The clear practice implication of this is that, at present, multiple session interventions aimed at all individuals exposed to traumatic events should not be used. Further, better designed studies that explore new approaches to early intervention are now required.

Abstract
BACKGROUND Anxiety disorders are a potentially disabling group of disorders which are prevalent in childhood and adolescence. The recognition of the early onset of anxiety disorders, and their successful treatment with medication in adults, has led to the growing interest in using medication for paediatric anxiety disorders. OBJECTIVES To assess the efficacy and tolerability of medication for treating paediatric anxiety disorders. SEARCH STRATEGY We searched the Cochrane Depression, Anxiety & Neurosis Group specialised register (CCDANCTR-Studies), MEDLINE (via PubMed 1966 to August 2008), EMBASE (1966 to August 2008), and PsycINFO (1972 to August 2008). Various electronic registers were searched for unpublished studies. Reference lists of retrieved articles were searched for additional studies. SELECTION CRITERIA All randomised controlled trials (RCTs) of pharmacotherapy in childhood/adolescent anxiety disorders. DATA COLLECTION AND ANALYSIS Two raters independently assessed RCTs for inclusion in the review, collated trial data, and assessed trial quality. Investigators were contacted to obtain missing data. Summary statistics were stratified by medication class, and by medication agent for the selective serotonin reuptake inhibitors (SSRIs). Dichotomous and continuous measures were calculated using a random effects model, heterogeneity was assessed, and subgroup/sensitivity analyses were undertaken. MAIN RESULTS 22 short-term (<= 16 weeks) RCTs were included in the analysis (2519 participants). The majority of the trials assessed the efficacy of the SSRIs (N = 15).Medication and placebo response occurred in 58.1% and 31.5% of patients, respectively (Number of studies (N) = 14, Number needed to treat (NNT) = 4). Medication was more effective than placebo in reducing overall symptom severity in OCD in a post-hoc comparison (N = 7, Weighted Mean Difference (WMD) = -4.45, 95%CI = -5.94, -2.97, n = 765). Medication was less well tolerated than placebo overall, though the absolute proportion of participants who withdrew due to drug-related adverse events was low (4.9%). AUTHORS' CONCLUSIONS Medication treatments can be effective in paediatric anxiety disorders, acting to reduce core symptoms, and should be considered as part of the treatment of these disorders. The greatest number of trials showing efficacy to date have assessed the SSRIs in treating paediatric OCD.There is no clear evidence to show that any particular class of medication is more effective or better tolerated than any other. As quantitative data was only available for the SSRIs and venlafaxine the routine use of benzodiazepines cannot be recommended, especially given concerns of dependency and treatment -related emergent adverse events associated with this class of drugs.Future RCTs could help identify potential clinical moderators of treatment efficacy. Studies of the long-term efficacy of medication treatment, optimal dosage, as well as direct comparisons of pharmacotherapy and psychotherapy are also warranted.
