RESUMO

OBJECTIVE: People with mood disorders have increased risk of comorbid medical diseases versus the general population. It is paramount to identify interventions to improve physical health in this population. METHODS: Umbrella review of meta-analyses of randomised controlled trials (RCTs) on pharmacological/non-pharmacological interventions for physical health outcomes/intolerability-related discontinuation in mood disorders (any age). RESULTS: Ninety-seven meta-analyses were included. Among youths, against placebo, in depression, antidepressants/antipsychotics had higher discontinuation rates; in bipolar depression, olanzapine+fluoxetine worsened total cholesterol (TC)/triglycerides/weight gain (WG) (large ES). In adults with bipolar disorder, olanzapine worsened HbA1c/TC/WG (moderate/large ES); asenapine increased fasting glucose (small ES); quetiapine/cariprazine/risperidone induced WG (small/moderate ES). In bipolar depression, lurasidone was metabolically neutral. In depression, psychological interventions improved physical health-related quality of life (PHQoL) (small ES), fasting glucose/HbA1c (medium/large ES); SSRIs improved fasting glucose/HbA1c, readmission for coronary disease, pain (small ES); quetiapine/aripiprazole/olanzapine induced WG (small to large ES). Exercise improved cardiorespiratory fitness (moderate ES). In the elderly, fluoxetine yielded more detrimental cardiovascular effects than sertraline/escitalopram (large ES); antidepressants were neutral on exercise tolerance and PHQoL. In mixed age groups, in bipolar disorder aripiprazole was metabolically neutral; in depression, SSRIs lowered blood pressure versus placebo and serotonin-noradrenaline reuptake inhibitors (small ES); brexpiprazole augmentation caused WG and was less tolerated (small ES); exercise improved PHQoL (moderate ES). CONCLUSIONS: Some interventions (psychological therapies, exercise and SSRIs) improve certain physical health outcomes in mood disorders, few are neutral, but various pharmacological interventions are associated with negative effects. Evidence from this umbrella review has limitations, should consider evidence from other disorders and should be integrated with recent evidence from individual RCTs, and observational evidence. Effective treatments with either beneficial or physically neutral profiles should be prioritized.

RESUMO

PURPOSE: Clozapine represents the criterion standard therapy for patients with treatment-resistant schizophrenia. Unfortunately, a significant percentage of such patients are also partial responders to clozapine. Consequently, several augmentation strategies have been proposed with various and sometimes controversial efficacy. Among these add-on treatments, lurasidone has been recently introduced and could represent a potential option, especially for the additional positive effect on cognitive symptoms. METHODS: This case series aims to determine possible advantages of lurasidone augmentation in four patients treated with clozapine, who were diagnosed with treatment-resistant schizophrenia. Positive and Negative Syndrome Scales were used to evaluate psychopathology, the Udvalg for Kliniske Undersøgelser scale for tolerability and safety. FINDING: All patients achieved a significant reduction of both positive and negative symptoms, with no significant adverse effects to be reported. IMPLICATIONS: Our observation suggests that lurasidone can lead to clinically significant improvements in psychopathology with a good tolerability profile when added to clozapine.

RESUMO

Promotion of good mental health, prevention, and early intervention before/at the onset of mental disorders improve outcomes. However, the range and peak ages at onset for mental disorders are not fully established. To provide robust, global epidemiological estimates of age at onset for mental disorders, we conducted a PRISMA/MOOSE-compliant systematic review with meta-analysis of birth cohort/cross-sectional/cohort studies, representative of the general population, reporting age at onset for any ICD/DSM-mental disorders, identified in PubMed/Web of Science (up to 16/05/2020) (PROSPERO:CRD42019143015). Co-primary outcomes were the proportion of individuals with onset of mental disorders before age 14, 18, 25, and peak age at onset, for any mental disorder and across International Classification of Diseases 11 diagnostic blocks. Median age at onset of specific disorders was additionally investigated. Across 192 studies (n = 708,561) included, the proportion of individuals with onset of any mental disorders before the ages of 14, 18, 25 were 34.6%, 48.4%, 62.5%, and peak age was 14.5 years (k = 14, median = 18, interquartile range (IQR) = 11-34). For diagnostic blocks, the proportion of individuals with onset of disorder before the age of 14, 18, 25 and peak age were as follows: neurodevelopmental disorders: 61.5%, 83.2%, 95.8%, 5.5 years (k = 21, median=12, IQR = 7-16), anxiety/fear-related disorders: 38.1%, 51.8%, 73.3%, 5.5 years (k = 73, median = 17, IQR = 9-25), obsessive-compulsive/related disorders: 24.6%, 45.1%, 64.0%, 14.5 years (k = 20, median = 19, IQR = 14-29), feeding/eating disorders/problems: 15.8%, 48.1%, 82.4%, 15.5 years (k = 11, median = 18, IQR = 15-23), conditions specifically associated with stress disorders: 16.9%, 27.6%, 43.1%, 15.5 years (k = 16, median = 30, IQR = 17-48), substance use disorders/addictive behaviours: 2.9%, 15.2%, 48.8%, 19.5 years (k = 58, median = 25, IQR = 20-41), schizophrenia-spectrum disorders/primary psychotic states: 3%, 12.3%, 47.8%, 20.5 years (k = 36, median = 25, IQR = 20-34), personality disorders/related traits: 1.9%, 9.6%, 47.7%, 20.5 years (k = 6, median = 25, IQR = 20-33), and mood disorders: 2.5%, 11.5%, 34.5%, 20.5 years (k = 79, median = 31, IQR = 21-46). No significant difference emerged by sex, or definition of age of onset. Median age at onset for specific mental disorders mapped on a time continuum, from phobias/separation anxiety/autism spectrum disorder/attention deficit hyperactivity disorder/social anxiety (8-13 years) to anorexia nervosa/bulimia nervosa/obsessive-compulsive/binge eating/cannabis use disorders (17-22 years), followed by schizophrenia, personality, panic and alcohol use disorders (25-27 years), and finally post-traumatic/depressive/generalized anxiety/bipolar/acute and transient psychotic disorders (30-35 years), with overlap among groups and no significant clustering. These results inform the timing of good mental health promotion/preventive/early intervention, updating the current mental health system structured around a child/adult service schism at age 18.

RESUMO

BACKGROUND AND RATIONALE: Treatment persistence combines clinician and patient judgment of efficacy, tolerability and safety into a comprehensive measure of effectiveness and is defined as the act of continuing a treatment over time. Studies have reported poor treatment persistence to antipsychotic medications in patients with schizophrenia. This study evaluated treatment persistence to lurasidone (LUR) in patients with schizophrenia in a real-world Italian setting. METHODS: This was a retrospective observational study of patients with schizophrenia who started treatment with LUR ≥ 6 months before inclusion. Following informed consent, data were collected starting from the index date (start of LUR treatment) at all visits occurring as per clinical practice. The primary endpoint was treatment persistence during the first 6 months, defined as the time between index date and all-cause discontinuation. Patients treated with LUR > 180 days were considered persistent. As secondary endpoint, treatment persistence was evaluated for a period of ≥ 18 months. RESULTS: Forty-five patients were enrolled and 41 (91.11%) completed the study. Forty-one patients (91.11%) were included in the eligible population as they initiated LUR treatment ≥ 6 months before data collection. Patients were 43.0 ± 15.89 years old and 61% were female. Twenty-two patients (53.66%) started LUR treatment in a hospital setting and 19 (46.34%) in an outpatient setting. Based on Clinical Global Impression-Severity scale (CGI-S) at LUR initiation, 12 patients (29.27%) were severely ill, 17.07% markedly ill, 19.51% moderately ill, 2.44% mildly ill and 4.88% borderline mentally ill. Thirty-two patients (78.05%) were treatment persistent for ≥ 180 days. Among the 19 patients observed for ≥ 18 months, 11 (57.89%) were persistent for ≥ 18 months. Among the 22 study patients observed for < 18 months, 12 (54.54%) were persistent. An improvement in schizophrenia severity according to CGI-S was observed at inclusion (following LUR therapy) compared to the index date. Six patients (14.63%) experienced at least one adverse drug reaction: akathisia (7.32%), extrapyramidal disorder (4.88%), hyperprolactinemia (2.44%), restlessness (2.44%), and galactorrhea (2.44%). None were serious. CONCLUSIONS: Persistence to LUR in patients with schizophrenia was relatively high: 78% and 58% of patients were still on LUR after 6 and 18 months of treatment, respectively. This may reflect LUR's relatively favorable balance between efficacy and tolerability, as well as favorable patient satisfaction and acceptance.

RESUMO

No study investigated whether the presence of specific medical comorbidities is associated with the type of traumatic event, in particular with terrorist attack (TA). In a group of subjects with posttraumatic stress disorder (PTSD), the current study investigated the association between the types of traumatic event (TA vs. other traumatic event [OTE]) and medical comorbidities, controlling for sex and PTSD duration. The Mini International Neuropsychiatric Interview, the Clinician-Administered PTSD Scale, and the Davidson Trauma Scale were administered to 84 subjects diagnosed with PTSD. Thirty-nine were victims of TA and 45 victims of OTE. TA was associated with higher prevalence of neoplasms (ß = 2.60, p = 0.02). Females were more protected than males from circulatory system comorbidities (ß = 1.47, p = 0.04), while PTSD duration was associated with higher prevalence of such comorbidities (ß = 0.005, p = 0.01). Females showed a higher prevalence of neoplasms than males (ß = 2.50, p = 0.02). Female sex was protective against metabolic syndrome (ß = -1.79, p = 0.02). Patients with PTSD due to TA and female patients should be considered for their higher prevalence of neoplasms, while male patients and those with higher symptom duration should be monitored for circulatory disease and metabolic syndrome. Symptom duration might be associated with circulatory and metabolic disease. Implications for tailored and timely psychopharmacological and psychotherapeutic intervention for PTSD are discussed focusing on these specific medical comorbidities.

RESUMO

In the Post-Traumatic Stress Disorder (PTSD) literature, no study assessed differences in symptom clusters among victims of terrorist attacks (TA) as compared with victims of other traumatic events. Due to the intentional nature of the harm infliction, TA may be expected to produce more severe symptoms, particularly avoidance, since this cluster was found to be a severity marker and a maintenance factor of the disorder. As several patients delay treatment-seeking, duration of untreated illness (DUI) is another problem potentially influencing PTSD severity. The current study explored differences in PTSD symptom clusters as a function of the traumatic event type (TA compared with other events), DUI, and sex. One hundred-eight patients with primary PTSD were administered The Clinician Administered PTSD Scale. Mean DUI was approximately 12 years, irrespective of the event type. Patients who had experienced TA had significantly more severe Avoidance/Numbing symptoms and general PTSD severity than those who had experienced other events. No significant effects emerged for DUI and sex on all clusters. Timely recognition and intervention on PTSD may include community psychoeducation programs about its symptoms. Tailored intervention on TA-related PTSD may focus on Avoidance/Numbing by including medication and psychotherapeutic approaches for this symptom cluster.

RESUMO

Introduction: Treatment-resistant depression (TRD) is commonly defined as the failure of at least two trials with antidepressant drugs, given at the right dose and for an appropriate duration. TRD is associated with increased mortality, compared to patients with a simple major depressive episode. This increased rate was mainly attributed to death from external causes, including suicide and accidents. The aim of our study is to identify socio-demographic and psychopathological variables associated with suicidal attempts in a sample of outpatients with TRD. Material and methods: We performed a monocentric observational study with a retrospective design including a sample of 63 subjects with TRD referred to an Italian outpatient mental health centre. We collected socio-demographic and psychopathological data from interviews and clinical records. Results: 77.8% of the sample (N=49) were females, the mean age was 49.2 (15.9). 33.3% (N=21) of patients had attempted suicide. 54% (N=34) of patients had a psychiatric comorbidity. Among the collected variables, substance use (p=0.031), psychiatric comorbidities (p=0.049) and high scores of HAM-D (p=0.011) were associated with the occurrence of suicide attempts. In the regression model, substance use (OR 6.779), psychiatric comorbidities (OR 3.788) and HAM-D scores (OR 1.057) were predictive of suicide attempts. When controlling for gender, only substance use (OR 6.114) and HAM-D scores (OR 1.057) maintained association with suicide attempts. Conclusion: The integrated treatment of comorbidities and substance abuse, which involves different mental health services, is fundamental in achieving the recovery of these patients. Our study supports the importance of performing a careful clinical evaluation of patients with TRD in order to identify factors associated with increased risk of suicide attempts.

RESUMO

INTRODUCTION: We aimed at evaluating hepatitis C virus (HCV) prevalence and treatment referral outcomes in a large population of drug users in Northern Italy. MATERIAL AND METHODS: Each participant underwent a quick capillary blood test. Positive participants underwent HCV RNA quantification. HCV RNA positive subjects were referred to treatment and evaluated immediately at the end of treatment and at 3 and 6 months after treatment. RESULTS: Of the 636 participants tested, 244 were positive. Intravenous drug use was more frequent among subjects who tested positive for HCV antibodies (99%). Among subjects who tested positive, 68% were HCV-RNA positive while 32% were negative. Among people referred to treatment, nearly 30% did not show up while 70% completed the treatment with success. Over 99% of people who started direct-acting antiviral agent (DAA) have a sustained response. DISCUSSION: We observed a significant higher prevalence of HCV positive subjects among people who inject drugs (99%) and we observed a high success rate for HCV treatment engagement. CONCLUSIONS: Rapid testing for HCV represents a potential tool for HCV screening among high-risk groups.

RESUMO

Cognitive deficits are associated with schizophrenia and show a progressive worsening, often being unresponsive to treatment. New antipsychotic molecules acting as antagonist at the serotoninergic 5-hydroxytryptamine receptor 7 (e.g. lurasidone) or partial agonists at dopamine D3 receptor (e.g. cariprazine) could have an impact on cognition in this patient group. The aim of the systematic review is to explore the efficacy of lurasidone and cariprazine in improving cognition in both animal models and human studies. The following terms: (lurasidone AND cognit*) OR (cariprazine AND cognit*) were searched in Web of Science from inception to December 2021. We included all studies that assessed changes in cognitive function after treatment with cariprazine or lurasidone. Of 201 selected articles, 36 were included. Twenty-four articles used animal models (rats, mice and marmosets), five evaluating the effects of cariprazine and 19 the effects of lurasidone. Twelve articles were clinical studies (cariprazine n = 2; lurasidone n = 10). In both animal and human studies lurasidone showed a greater efficacy on cognitive performance compared to placebo, quetiapine, ziprasidone or treatmentas- usual. Cariprazine was superior to other antipsychotics in improving cognitive functions in both animal and human studies. The cognitive effect of lurasidone could be explained by its potent antagonism at the 5-HT7 receptors combined with partial agonism at 5-HT1A receptors. The pro-cognitive effect of cariprazine is probably explained by its very high affinity for D3 receptors. Head-to-head studies comparing lurasidone and cariprazine are needed to establish the "first-choice" treatment for cognitive dysfunction associated with schizophrenia.

RESUMO

BACKGROUND: Epigenetics of Autism Spectrum Disorders (ASD) is still an understudied field. The majority of the studies on the topic used an approach based on mere classification of cases and controls. OBJECTIVE: The present study aimed at providing a multi-level approach in which different types of epigenetic analysis (epigenetic drift, age acceleration) are combined. METHODS: We used publicly available datasets from blood (n = 3) and brain tissues (n = 3), separately. Firstly, we evaluated for each dataset and meta-analyzed the differential methylation profile between cases and controls. Secondly, we analyzed age acceleration, epigenetic drift and rare epigenetic variations. RESULTS: We observed a significant epi-signature of ASD in blood but not in brain specimens. We did not observe significant age acceleration in ASD, while epigenetic drift was significantly higher compared to controls. We reported the presence of significant rare epigenetic variations in 41 genes, 35 of which were never associated with ASD. Almost all genes were involved in pathways linked to ASD etiopathogenesis (i.e., neuronal development, mitochondrial metabolism, lipid biosynthesis and antigen presentation). CONCLUSION: Our data support the hypothesis of the use of blood epi-signature as a potential tool for diagnosis and prognosis of ASD. The presence of an enhanced epigenetic drift, especially in brain, which is linked to cellular replication, may suggest that alteration in epigenetics may occur at a very early developmental stage (i.e., fetal) when neuronal replication is still high.

RESUMO

Major depression is a common comorbidity in autism spectrum disorder (ASD), often difficult to identify and to treat. Autistic subjects are more at risk for suicidal thoughts and behaviors compared to typically developing peers. Unfortunately, ASD individuals are more frequently treatment-resistant and often show side-effects which reduce efficacy. Intranasal esketamine has been recently approved as an add-on medication for treatment-resistant depression (TRD), but it has never been used in ASD with comorbid major depression. Of note, a pilot study of intranasal ketamine has shown no effect on social withdrawal in ASD without depression. The present case report describes the first girl with ASD and comorbid TRD treated with intranasal esketamine.

RESUMO

RATIONALE: The use of intravenous valproate is not approved for clinical practice in psychiatry. Literature data pointed out for a potential usefulness of this route of administration for valproate, but there is no actual consensus. OBJECTIVES: The aim of the present systematic review is to assess the effectiveness of intravenous valproate in agitation as well as general safety. METHODS: A systematic review of studies evaluating the use of intravenous valproate in agitation was conducted. Additionally, safety was evaluated in all randomized trials involving the use of intravenous valproate in all medical conditions (epilepsy, migraine and psychiatric conditions). RESULTS: For the systematic review on effectiveness in agitation, the search yielded 965 articles overall. After removing duplicates, 9411 articles were screened by title and abstract, and 39 of these were evaluated at a full-text level. Six studies were considered eligible for qualitative synthesis: one RCT and case report (n = 3), followed by cohort studies (n = 2). For the systematic review on safety, twenty-two RCTs were considered eligible for quantitative synthesis. CONCLUSION: Intravenous valproate seems efficacious in reducing agitation in psychiatric patients; it generally appears safe compared to other neuroleptics or antiepileptics. However, the evidence is still not strong as it  relies mainly on open-label studies or case series.

RESUMO

Background: Treatment-resistant Depression (TRD) represents a widespread disorder with significant direct and indirect healthcare costs. esketamine, the S-enantiomer of ketamine, has been recently approved for TRD, but real-world studies are needed to prove its efficacy in naturalistic settings. Objectives: Evaluate the effectiveness and safety of esketamine nasal spray in a clinical sample of patients with TRD from several Italian mental health services. Methods: REAL-ESK study is an observational, retrospective and multicentric study comprising a total of 116 TRD patients treated with esketamine nasal spray. Anamnestic data and psychometric assessment (MADRS, HAMD-21, HAM-A) were collected from medical records at baseline (T0), one month (T1) and three month (T2) follow-ups. Results: A significant reduction of depressive symptoms was found at T1 and T2 compared to T0. A dramatic increase in clinical response (64.2 %) and remission rates (40.6 %) was detected at T2 compared to T1. No unexpected safety concerns were observed, side effects rates were comparable to those reported in RCTs. No differences in efficacy have been found among patients with and without psychiatric comorbidities. Limitations: The open design of the study and the absence of a placebo or active comparator group are limitations. The study lacks an inter-rater reliability evaluation of the assessments among the different centres. Side effects evaluation did not involve any specific scale. Conclusions: Our findings support the safety and tolerability of esketamine in a real-world TRD sample. The later response and the non-inferiority in effectiveness in patients with comorbidities represent novel and interesting findings.

RESUMO

BACKGROUND: There is extensive evidence for volumetric reductions in the hippocampus in patients with anorexia nervosa (AN), however the impact on function is unclear. Pattern separation and recognition are hippocampus-dependent forms of learning thought to underlie stimulus discrimination. METHODS: The present study used the Mnemonic Similarity Task to investigate pattern separation and recognition for the first time in patients with AN (N = 46) and healthy controls (N = 56). An Analysis of Covariance examined between-group differences, controlling for age, antidepressant use and method of task delivery (remote vs. in person). RESULTS: When controlling for covariates, pattern recognition memory scores were lower in the AN group with a medium effect size (d = 0.51). In contrast, there was a small effect whereby patients with AN had a greater pattern separation score than controls (d = 0.34), albeit this difference was not significant at the p = 0.05 threshold (p = 0.133). Furthermore, pattern separation and recognition memory abilities were not related to age, body mass index, eating disorder psychopathology or trait anxiety levels. CONCLUSIONS: This preliminary study provides initial evidence for an imbalance in pattern separation and recognition abilities in AN, a hippocampus-dependent cognitive ability. Further studies should endeavour to investigate pattern separation and recognition performance further in AN, as well as investigate other hippocampus-dependent functions.


The hippocampus is an area of the brain that is vital for memory and learning, and it is not understood the extent to which its function is impaired in anorexia nervosa (AN). This paper used the Mnemonic Similarity Task to assess pattern separation, a hippocampus-dependent form of memory, in AN. This task involves showing participants a sequence of objects, who then categorise them as "indoor" or "outdoor" objects. Participants are later shown a sequence of objects, although some of the images are replaced by a similar but slightly different image. The task involves recognising whether an image has previously been seen (pattern recognition) and also whether it is similar to, but distinct, from a previous image (i.e. pattern separation). In this study, individuals with AN showed reduced performance in pattern recognition, when statistically controlling for their age, how the task was delivered and their use of antidepressant medication. However, their performance in pattern separation was intact. This may indicate an imbalance in this hippocampus-dependent form of memory in AN.

RESUMO

PURPOSE: Posttraumatic stress disorder (PTSD) includes different symptoms: re-experiencing, avoidance of reminders and numbing, and hyperarousal. Although questionnaires are widely used, clinician-administered interviews provide a more comprehensive exploration of symptoms. Few studies examined the convergence between clinician-rated and patient-reported general severity and symptoms, with mixed findings. We explored the association between clinician-rated and patient-reported general severity and symptoms and the moderator role of gender in PTSD patients referred to a specialized outpatient service. DESIGN AND METHODS: The Clinician-Administered PTSD Scale and Davidson Trauma Scale were administered to 56 patients. FINDINGS: Patients classified by clinicians as with higher avoidance/numbing symptoms and women classified with higher hyperarousal symptoms reported higher general severity. PRACTICE IMPLICATIONS: The assessment of the patients reporting high severity should focus on hyperarousal, particularly for women.

RESUMO

Background: Several neurobiological mechanisms have been proposed to support the hypothesis of a higher COVID-19 risk in individuals with autism spectrum disorder (ASD). However, no real-world data are available on this population. Methods: We compared the period prevalence (March-May 2020) and symptom presentation of COVID-19 infections between a sample of individuals with severe ASD (n = 36) and the staff personnel (n = 35) of two specialized centers. Anti-SARS-Cov-2 antibody positivity was used as a proxy of infection. Additionally, we evaluated vaccine side effects in the same groups. Results: No significant difference was found between the prevalence of COVID-19 positivity between autistic participants and staff personnel. Levels of antibodies against the spike protein and the receptor binding domain were not significantly different between autistic and staff participants. The level of antibodies against the N-terminal domain were higher in autistic individuals. There was a significant difference between the prevalence of symptomatic COVID-19 in autistic participants (9.1%) compared to staff personnel (92.3%). The most frequent side effect among autistic participants was light fever. Conclusions: The present study provides preliminary data on COVID-19 transmission and presentation in ASD. Our data do not support the hypothesis of a higher susceptibility and severity of COVID-19 in people with ASD.

RESUMO

OBJECTIVES: The association between post-traumatic stress disorder (PTSD) and medical comorbidities is controversial since most studies focused on specific comorbidity and victim types. In Italy, data on this issue are scarce. A comprehensive evaluation of all the ICD medical categories co-occurring in PTSD may orient assessment and treatment during clinical and forensic practice. This is the first study evaluating all the ICD physical comorbidities and gender-related differences in Italian PTSD patients. Eighty-four PTSD patients (36 females, 48 males) were included. The Clinician-Administered PTSD Scale, Mini International Neuropsychiatric Interview and Davidson Trauma Scale were administered. RESULTS: Most patients had a PTSD consequent to an accident and half of them presented extreme symptom severity. No gender differences emerged on symptom severity/duration and age at the event. Metabolic (39.29%), circulatory (20.24%) and musculoskeletal systems/connective tissue diseases (17.86%) were the most frequent comorbidities. Metabolic/circulatory diseases were more frequent among males (p = 0.019 and p = 0.027, respectively) while females more frequently showed neoplasms (p = 0.039). Physical comorbidities represent a serious complication in PTSD patients and are more prevalent than in the Italian population. While gender is not associated with symptom presentation, it seems to play a key role in specific comorbidities including metabolic, circulatory and neoplastic diseases.

RESUMO

OBJECTIVES: To identify possible differences, in terms of duration and severity of Post-Traumatic Stress Disorder, between victims of terrorist attacks and subjects who underwent other types of traumatic events. METHODS: A sample of subjects suffering from PTSD was selected. After a clinical interview aimed at the collection of anamnestic data, CAPS to confirm the diagnosis of PTSD and DTS to assess frequency and severity of post-traumatic symptoms were administered. One-way ANOVA was used in order to compare the differences in the parameters analysed through the DTS scales and its clusters between the victims of terrorist attacks and patients undergone other traumatic events. RESULTS: The duration of PTSD was 258 +/ - 144.9 months for people who underwent a terrorist attack and 41.6 +/ - 11.8 months for victims of other traumatic events. As regards the severity of the disorder, the total score of the DTS scale was 65.6 +/ - 26.9 in victims of terrorist attacks and 78.2 +/ - 28.2 in people who undergone other traumatic events. However, the difference was not statistically significant; Avoidance and Hypervigilance clusters showed an important statistical significance. CONCLUSIONS: No significant differences are present in terms of severity, showing that PTSD is a disabling disorder regardless the type of event that triggers it; however, a significant difference in terms of duration of the disorder leads to reflec on the importance of an early diagnostic process aimed toward the victims of terrorism, in order to avoid the risk of chronicity and progression to other psychiatric disorders such as depression.
