OBJECTIVE: To determine the associations between PTSD, psychotropic medication use, and the risk for dementia. DESIGN: Retrospective cohort. PARTICIPANTS: Nationwide sample of US veterans (N = 417,172) aged ≥56 years during fiscal year (FY) 2003 without a diagnosis of dementia or mild cognitive impairment at baseline (FY02-03) and ≥1 clinical encounter every 2 years during follow-up (FY04-12). MEASURES: Demographic characteristics; diagnosis of PTSD, dementia, and medical and psychiatric comorbidity (defined by ICD-9 codes); and psychotropic medication use including selective serotonin reuptake inhibitors (SSRI), serotonin-norepinephrine reuptake inhibitors (SNRI), novel antidepressants (NA), benzodiazepines (BZA), and atypical antipsychotics (AA)...

Post-traumatic stress disorder (PTSD) is a condition that develops after an individual has experienced a major trauma. Currently, selective serotonin reuptake inhibitors (SSRIs) like fluoxetine are the first-line choice in PTSD drug treatment but their moderate response rates and side effects indicate an urgent need for the development of new treatment. Physical activity is known to improve symptoms of certain neuropsychiatric disorders. The present study investigated the effects of moderate treadmill exercise, the antidepressant fluoxetine and the combined treatment on behavioural deficits, and hypothalamic-pituitary-adrenal (HPA) axis dysfunction...

Ketamine has been reported to be an efficacious antidepressant for major depressive disorder (MDD) and posttraumatic stress disorder (PTSD). Most recently, ketamine has also been shown to be prophylactic against stress-induced depressive-like behavior in mice. It remains unknown, however, when ketamine should be administered relative to a stressor in order to maximize its antidepressant and/or prophylactic effects. Moreover, it is unknown if ketamine can be prophylactic against subsequent stressors. We systematically administered ketamine at different time points relative to a fear experience in order to determine when ketamine is most effective at reducing fear expression or preventing fear reactivation...

OBJECTIVE: The comorbidity of posttraumatic stress disorder (PTSD) with antenatal depression poses increased risks for postpartum depression and may delay or diminish response to evidence-based depression care. In a secondary analysis of an 18-month study of collaborative care for perinatal depression, the authors hypothesized that pregnant, depressed, socioeconomically disadvantaged women with comorbid PTSD would show more improvement in the MOMCare intervention providing Brief Interpersonal Psychotherapy and/or antidepressants, compared to intensive public health Maternity Support Services (MSS-Plus)...

Chronic use (>90 Days) of opioid analgesics significantly increases the risk of development of new depression episodes (NDE). It is unclear whether depression that develops in this manner is similar to or different from NDE in persons not exposed to opioid analgesic use (OAU). METHODS: VA patients were classified into two groups, those who did not receive an opioid and developed depression (non-OAU+NDE, n=4314) and those that had >90 days OAU and developed NDE (OAU+NDE, n=444). OAU+NDE patients were compared to non-OAU+NDE in terms of depression severity (PHQ-9 scores), incidence of PTSD, other anxiety disorders and substance use disorders after NDE, receipt of acute phase antidepressant treatment, dual antidepressant treatment, mood stabilizers and atypical antipsychotics...

BACKGROUND: Open-label trials suggest that escitalopram (up to 20 mg/d) is an effective treatment for some, but not all posttraumatic stress disorder (PTSD) patients. Higher doses of escitalopram effectively reduced major depression symptoms in patients who had not responded to regular doses. The current study examines the efficacy, tolerability, and adherence to high-dose escitalopram in PTSD. METHODS: Forty-five PTSD patients received 12 weeks of gradually increasing doses of escitalopram reaching 40 mg daily at 4 weeks...

There is a dearth of evidence on the effectiveness of pharmacological treatment for refugees with trauma-related disorders. The present paper provides an overview of available literature on the subject and discusses the transferability of results from studies on other groups of patients with post traumatic stress disorder (PTSD). We conducted a systematic review of published treatment outcome studies on PTSD and depression among refugees. Fifteen studies were identified and reviewed. Most studies focused on the use of antidepressants...

REVIEW
Matthew J Friedman, Nancy C Bernardy
Posttraumatic stress disorder (PTSD) is a prevalent, disabling, and often chronic condition that may develop following exposure to a traumatic event. Despite the immense social and economic ramifications of PTSD, there has been relatively little recent development of new pharmacotherapies. The majority of pharmacological randomized clinical trials (RCTs) that has been conducted are now dated. Existing treatments for PTSD primarily have come out of research that tested medications developed for other disorders such as antidepressants, anti-hypertensives, antipsychotics, anticonvulsants, and anxiolytics...

BACKGROUND: There has been increasing research on posttraumatic stress disorder (PTSD) following childbirth in the last two decades. The literature on predictors of who develops posttraumatic stress symptoms (PSS) suggests that both vulnerability and birth factors have an influence, but many studies measure predictors and outcomes simultaneously. OBJECTIVE: In this context, we aimed to examine indirect and direct effects of predictors of PSS, which were measured longitudinally...

OBJECTIVE: Selective serotonin reuptake inhibitors (SSRIs) remain the first-line treatment for posttraumatic stress disorder (PTSD). However, adjunctive atypical antipsychotics are often used to target residual or refractory symptoms. Asenapine is a novel atypical antipsychotic that possesses a high serotonin (5-HT2A) to dopamine (D2) affinity ratio and alpha-adrenergic antagonism, which may be advantageous in treating PTSD. This pilot study aimed to identify the therapeutic potential of asenapine as an adjunctive treatment for PTSD...

BACKGROUND: The pharmacological treatment of post-traumatic stress disorder (PTSD) is extremely challenging, as no specific agent has been developed exclusively to treat this disorder. Thus, there are growing concerns among the public, providers and consumers associated with its use as the efficacy of some agents is still in question. AIMS: We applied a dimensional and symptom cluster-based approach to better understand how the heterogeneous phenotypic presentation of PTSD may relate to the initiation of pharmacotherapy for PTSD initial episode...

OBJECTIVE: Post-traumatic stress disorder (PTSD) displays high co-morbidity with major depression and treatment-resistant depression (TRD). Earlier work demonstrated exaggerated depressive-like symptoms in a gene×environment model of TRD and an abrogated response to imipramine. We extended the investigation by studying the behavioural and monoaminergic response to multiple antidepressants, viz. venlafaxine and ketamine with/without imipramine. METHODS: Male Flinders sensitive line (FSL) rats, a genetic model of depression, were exposed to a time-dependent sensitisation (TDS) model of PTSD and compared with stress naive controls...

Serotonin syndrome (SS) is a potentially life-threatening adverse drug reaction that may occur in patients treated with serotonin agonist medications. Medications responsible for serotonin syndrome include commonly prescribed antidepressants, anxiolytics, analgesics, and antiemetics. Veterans with post-traumatic stress disorder (PTSD) are at risk for polypharmacy with serotoninergic medications, given their psychological comorbidities and service-related musculoskeletal injuries. The perioperative period is a particularly vulnerable time owing to the use of high-dose anxiolytics and antiemetics frequently administered in this period, and places PTSD patients at higher risk of SS...

There is an increasing risk of mental disorders, such as acute stress disorder (ASD), post-traumatic stress disorder (PTSD) and depression among survivors who were trapped in rubble during earthquake. Such long-term impaction of a single acute restraint stress has not been extensively explored. In this study, we subjected mice to 24-hour-restraint to simulate the trapping episode, and investigated the acute (2 days after the restraint) and long-term (35 days after the restraint) impacts. Surprisingly, we found that the mice displayed depression-like behaviors, decreased glucose uptake in brain and reduced adult hippocampal neurogenesis 35 days after the restraint...

OBJECTIVE: Co-morbid depression with post-traumatic stress disorder (PTSD) is often treatment resistant. In developing a preclinical model of treatment-resistant depression (TRD), we combined animal models of depression and PTSD to produce an animal with more severe as well as treatment-resistant depressive-like behaviours. METHODS: Male Flinders sensitive line (FSL) rats, a genetic animal model of depression, were exposed to a stress re-stress model of PTSD [time-dependent sensitisation (TDS)] and compared with stress-naive controls...

BACKGROUND: Post-traumatic stress disorder (PTSD) has been linked to hypertension, but most research on PTSD and hypertension is cross-sectional, and potential mediators have not been clearly identified. Moreover, PTSD is twice as common in women as in men, but understanding of the PTSD-hypertension relationship in women is limited. We examined trauma exposure and PTSD symptoms in relation to incident hypertension over 22 years in 47 514 civilian women in the Nurses' Health Study II. METHOD: We used proportional hazards models to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for new-onset hypertension (N = 15 837)...

OBJECTIVE: Finding effective and lasting treatments for patients with Major Depressive Disorder (MDD) that fail to respond optimally to initial standard treatment is a critical public health imperative. Understanding the nature and characteristics of patients prior to initiating "next-step" treatment is an important component of identifying which specific treatments are best suited for individual patients. We describe clinical features and demographic characteristics of a sample of Veterans who enrolled in a "next-step" clinical trial after failing to achieve an optimal outcome from at least one well-delivered antidepressant trial...

Exposure to severe stress can lead to the development of neuropsychiatric disorders such as depression and post-traumatic stress disorder (PTSD) in at-risk individuals. Gastrodin (GAS), a primary constituent of an Oriental herbal medicine, has been shown to effectively treat various mood disorders. Thus, the present study aimed to determine whether GAS would ameliorate stress-associated depression-like behaviors in a rat model of single prolonged stress (SPS)-induced PTSD. Following the SPS procedure, rats received intraperitoneal administration of GAS (20, 50, or 100 mg/kg) once daily for 2 weeks...

Refugees are a highly traumatized and culturally diverse group of patients who present many clinical challenges. Refugees have a high prevalence of traumas from torture, ethnic cleansing, and the effects of long civil wars. The most common diagnoses associated with the effects of such traumas are posttraumatic stress disorder (PTSD) or PTSD with comorbid depression; however, psychosis and neurocognitive disorders are also common. For those with PTSD, a suggested treatment approach is long-term supportive psychotherapy with drug treatment directed at reducing the most disruptive symptoms, such as insomnia, nightmares, and irritability or psychosis...
