Introduction
According to the two-factor theory of delusional belief (Coltheart. Ann N Y Acad Sci 2010; 1191 16-26), explaining the presence of a delusion requires a combination of two neuropsychological impairments. The first deficit initially prompts the delusional belief and defines its content, whereas the second deficit – aberrant belief evaluation – interrupts the rejection of a delusional belief and is common for different types of delusions. The second deficit is associated with compromised functioning of the right ventral frontal/anterior insular cortex (r-VF/AI; Darby et al. Brain 2017; 140 497-507). However, neural correlates of the first deficit in different types of delusions remain obscure.ObjectivesThe aim of the study was to search for regions whose functional connectivity with r-VF/AI is different between patients with somatic delusions (SD) and persecutory delusions (PD) and to further clarify the results by comparing clinical groups with healthy controls. We hypothesized that each clinical group is characterized by aberrant functional connectivity between a region, associated with poor belief evaluation (r-VF/AI), and a region, presumably associated with a neuropsychological impairment specific to the corresponding type of delusions.Methods
Patients with delusional disorder or paranoid schizophrenia (n = 23) and healthy controls (n = 9; 5 females; mean age 36.2 ± 1.3) underwent resting-state fMRI (Philips Ingenia 3T). Nine patients had SD (5 females; mean age 40.3 ± 7.9) and fourteen patients had PD (3 females; mean age 35.6 ± 10.2). The clinical groups were compared in terms of whole-brain functional connectivity of r-VF/AI (ROI-to-voxel analysis in CONN; RRID:SCR_009550; www.nitrc.org/projects/conn). Statistical thresholds were p < .005 voxelwise, p[FDR] < .05 clusterwise. Each clinical group was compared with controls in terms of functional connectivity between r-VF/AI and previously identified regions with between-group differences in connectivity (ROI-to-ROI analysis). Age was a covariate of no interest in all analyses.ResultsPatients with SD compared to patients with PD and healthy individuals had higher functional connectivity between the r-VF/AI and a cluster in the right precentral and postcentral gyri extending to supramarginal and superior frontal gyri (Figure 1).Image:ConclusionsThe regions whose functional connectivity with r-VF/AI was aberrant in patients with SD are involved in the processing of tactile, proprioceptive, and visceral information. Our results coincide with a suggestion that the evaluation of beliefs related to bodily sensations is disturbed in patients with SD.Research was supported by RFBR grant project 21-515-12007.Disclosure of InterestNone Declared

Authors: Albalushi M. K. 
Published: August 2024

IntroductionBackground:Somatic symptoms disorders are usually comorbid with depressive disorders despite that there is little evidence for effective treatment for it. Repetitive transcranial magnetic stimulation (rTMS) have been approved by FDA for mildly resistance depression. From this point we hypothesized that rTMS delivered over the prefrontal cortex (PFC) may be useful in somatic symptoms disorder. Therefore, in our case report we want to shed light on the potential effectiveness of rTMS in somatic symptoms disorder.Objectivescase reportMethodscase reportResultsCase Report:
A 65-year-old Omani female with multiple medical comorbidities on multiple medications. She presented complaining of multiple somatic complains in the last 2 years after visiting multiple clinics and underwent several specialists’ examinations, investigations and procedure for somatic treatments, all of them where normal.Then patient was seen by different psychiatric clinic multiple anti-depressant and adjuvant anti-psychotic medication were try, patient still not improve.Patient get admitted to hospital for observation and management. Initially she was preoccupying by her somatic complain kept on Fluoxetine and Olanzapine along with that topiramate was added, but still with minimal improvement. Then rTMS was added to her management plan following Intermittent theta burst (iTBS) rTMS protocol. After complete all sessions of rTMS patient was recovering from her all symptoms, no complain report from her.ConclusionsConclusion: our case highlights the important of investigated more thoroughly in rTMS as treatment option for Persistent Somatic symptoms Disorder.Disclosure of InterestNone Declared

IntroductionPaediatric cancer survivors have a risk for neuropsychological impairment due to the disease and the treatment received. These affections have been neglected in the follow-up of these patients. It is important to identify the most valid outcomes in the evaluation of neurocognitive sequelae in childhood cancer survivors.ObjectivesThis work aims to compare the results obtained between subjective perception of caregivers and objective cognitive performance based on validated attention tests.MethodsIn a randomized controlled and unblinded trial to demonstrate the benefit of video games on different neurocognitive areas in cancer survivors, we studied attention functioning before and after the intervention program. The attention deficit subscale from the Behavior Assessment System for Children 3rd edition (BASC-3), self- and parent-reported versions, and the Continuous Performance Test, 3rd edition (CPT 3) will be used as outcomes (z scores: mean = 0, S.D. = 1).ResultsWe observed an improvement in attention after intervention using the CPT-3 (omissions z = 1.2; hit reaction time z = 3.4; hit reaction time block change z = 1.2 versus hit reaction time z = 3.6 without other atipycal z scores after intervention), changing the attentional pattern from “ADHD” to “slowed”. However, in the parent-reported version of the BASC-3, a worsening in the attention subscale is observed (z = 0.3 pre-intervention vs z = 1.0 post-intervention) while the self-reported version of the patient didn’t show any significant changes (z = 1.4 pre-intervention vs z = 1.1 post-intervention).ConclusionsIt is essential to use objective tests to measure neurocognitive sequelae in these patients. Subjective surveys can provide additional information, but not substitute the above.Disclosure of InterestNone Declared

Introduction
Diagnostic criteria for narcissistic personality disorder primarily focus on grandiosity and significance. In psychotherapeutic work, it is important to distinguish two subtypes of pathological narcissism: narcissistic grandiosity and narcissistic vulnerability. One of the manifestations of narcissistic traits is unstable or unformed self-esteem, manifested in attempts to conform to ideals. A part of modern society perceives the female body as an object that “needs to be looked at”. Self-objectification refers to a learned pattern of self-assessment of the importance of one’s body and appearance compared to other aspects of the self. Self-observation and comparison of oneself with others is one of the manifestations of self-objectification. With acts of auto aggression, the body becomes a tool or a means to solve psychological problems. In order for this to become possible, the ability to objectify your body “to look at it from the outside” plays an important role.ObjectivesAnalysis of the relationship between non-suicidal self-injurious behavior and narcissistic personality traits in young women with depression and young women without a psychiatric diagnosis.MethodsТhe study included 49 women divided into two groups. The first group included 24 patients with depression undergoing inpatient treatment (mean age 18.4). The second group included 25 healthy subjects (mean age 18 years). The methods: The answer to the question “Sometimes I purposely injure myself” was used as an indicator of self-harm (NSSI) (five-point Likert scale); “Ich structure test” (ISTA); “Physical Appearance Comparison Scale-Revised” (PACS-R).Results
In the clinical group, a significant association of severity of NSSI with indicators of “deficit narcissism” was revealed (Spearman r=,534*). Correlations were found between the severity of NSSI and PACS-R (r=,344**). In the clinical group, there was no connection between “Comparison with others” and narcissistic traits. In a group of healthy subjects, significant associations of NSSI severity with “destructive narcissism” (,572**) and PACS-R (,576**) were revealed. In the clinical group, the severity of NSSI is associated with a more serious pathology - the lack of formation of “normal” narcissism, and in the healthy group it is more likely to be deformed narcissism. Self-objectification and comparison of oneself with others in the clinical group is not associated with manifestations of narcissistic traits, such connections are demonstrated in the group of healthy young women.ConclusionsIt is shown that in the clinical group of depressed young women, the severity of self-harming behavior is associated with “deficit narcissism”, and in healthy young women, first of all, with “destructive narcissism” with an increased need to compare themselves with others.Disclosure of InterestNone Declared
Experiences and attitudes of early career psychiatrists towards ECT – an international study
Authors: Tapoi C. 
Published: August 2024

AbstractIntroductionElectroconvulsive therapy (ECT) is a psychiatric intervention that has proven effectiveness and safety in various psychiatric conditions, such as major depressive disorder, prolonged or severe manic episodes and catatonia. Despite positive scientific evidence, ECT was always seen as controversial by patients, caregivers, and even some psychiatrists, which lead to a decrease in its use over the years.ObjectiveTo investigate the way young psychiatrists view the place of ECT in modern psychiatry by assessing their knowledge, attitude and access to training opportunities in ECT.MethodsAn anonymous survey was disseminated online among early career psychiatrists and psychiatric trainees. The questionnaire consisted of 36 multiple-choice and Likert scale questions.ResultsMost of our respondents consider ECT both an effective and a safe treatment option and would recommend ECT to their patients when indicated. Early career psychiatrists who had access to ECT training are more knowledgeable about the indications, precautions and side effects of this method, but more than half of the participants mentioned ECT training was unavailable during their residency programme. Almost all respondents stated that they are interested in enhancing their theoretical and practical competencies in ECT.ConclusionsEarly career psychiatrists have a positive attitude towards ECT but express the need of targeted education aimed at improving levels of knowledge about ECT.Disclosure of InterestNone Declared

Authors: De Pieri M. , Rochas V. , Sabe M. , Michel C. , Kaiser S. 
Published: August 2024

IntroductionResponse to antipsychotic medications (AP) is subjected to a wide and unpredictable variability and efforts were directed to discover predictive biomarkers to personalize treatment. Electroencephalography abnormalities in subjects with schizophrenia were reported, as well as a pattern of EEG changes induced by APsObjectivesThe aim of this review is to provide a synthesis of the EEG features that are related to APs efficacy, including both pre-treatment signatures and changes induced by APs during treatment.MethodsA systematic review of English articles using PubMed, PsychINFO and the Cochrane database of systematic reviews was undertaken in april 2023. Additional studies were added by hand-search. Studies having as an endpoint the relationship between AP-related clinical improvement and electroencephalographic features were included. Heterogeneity prevented a quantitative synthesis.ResultsOut of 1232 records screened, 22 studies were included in a final qualitative synthesis. Included studies evaluated resting-state and task-related power spectra, functional connectivity, microstates and epileptic abnormalities. At pre-treatment EEG, the most relevant predictors of a poor response were a change in theta power compared to healthy control, a high alpha power and connectivity, a diminished beta power in resting-state. Considering EEG during treatment, an increased theta power, a reduced beta-band activity, an increased alpha activity, a decreased coherence in theta, alpha and beta-band were related to a favorable outcome.Conclusions
EEG is promising as a method to create a predictive biomarker for response to APs; further investigations are warranted to harmonize and generalize the contradictory results of reviewed studies.Disclosure of InterestNone Declared
Limbic encephalitis – A case report of atypical dementia syndrome with potentially therapeutic consequence
Authors: Xepapadakos F. , Kawohl W. 
Published: August 2024

IntroductionLimbic encephalitis (LE) is a subacute or chronic, non-infectious inflammation of the brain, usually occurring in adulthood, with predominant involvement of mesiotemporal structures and a clinical manifestation consisting mainly of new memory impairment, affective disorder, temporal lobe epilepsy, psychoses, etc.ObjectivesTo point out the importance of knowledge of potentially treatable dementia syndromes such as atypical manifestation of probably LE.MethodsWe present a clinical case of a 47-years-old woman with an atypical dementia syndrome and typical radiological findings corresponding to a LE, among others, but without the previously known immunological antibodies.ResultsAccording to the literature, the diverse subsyndromes of LE can be subsumed under the two main categories of “paraneoplastic” and “non-paraneoplastic”. In addition to the acute and subacute courses, there is increasing evidence for chronic, slowly progressive courses, which expand the spectrum of potentially treatable dementia syndromes. Understanding and knowledge of the broad, clinical syndrome of LE have increased dramatically in recent years. Both nosological classification through differentiated diagnosis and specific therapeutic protocols have become increasingly developed and established. Nevertheless, there are rare clinical cases with a clinical phenotype and radiological findings that correspond to LE, but are both non-paraneoplastic in origin and seronegative with respect to the previously known immunological typing by autoantibodies. This gray area of nosological entity represents a diagnostic and therapeutic challenge.ConclusionsThe authors would like to point out the importance of an adequate diagnosis of the forms of LE that have been nosologically classified so far and are partly well treatable. Limbic encephalitis is an important differential diagnosis in dementia, especially in young patients with atypical courses. There is a need for further research regarding better diagnosis and therapy of the so far immunologically unidentifiable forms of clinical LE.Literature:Bazir Ahmad et al., Practical Neurology 2011Guidelines of the German Neurological Society (DGN), 2008Leypoldt et al., Akt Neurol 2012Prüss et al., Neurology 2012Disclosure of InterestNone Declared

IntroductionAnatomical Therapeutic Chemical (ATC) indication-based classification system is the World Health Organization (WHO) drug classification system and it is widely used in clinical and researh practice, however there has been questions around the scientific base of this (1, 2). Neuroscience-based Nomenclature (NbN) has been developed by representatives from 5 international organizations, with specific expertise in psychopharmacology, to address the issues around neuropsychopharmacological drug classification and improve the focus on pharmacological domains and mode of action:ECNP – European College of NeuropsychopharmacologyACNP – American College of NeuropsychopharmacologyAsCNP – Asian College of NeuropsychopharmacologyCINP – International College of NeuropsychopharmacologyIUPHAR – International Union of Basic and Clinical PharmacologyReferences:1.

The ethical clearance of the study was obtained from King’s College London. We prepared an online survey (https://forms.gle/FCSdVTFH4U5QNn5t8) with a multinational group of early career pscyhiatrists who met through the CINP and EFPT, and test-run the survey with a small group of psychiatric trainees. The online survey was then disseminated via emailing lists and groups of early careers psychiatrists as well as through social media.ResultsAt the time of this abstract submission, the data collection is ongoing. Results will include analyses of the experience with different drug classifcations systems, awareness, views and attainment of NbN, stratified according to the demographic data (country, careers status, main work setting).ConclusionsThe findings from this study will shed light on the views and needs of early career psychiatrists on the topic from clinical and academic aspects, a previously unexplored perspective on drug classification systems. The findings can inform the planning of various strategies to address areas to improve the use and teaching of these tools.Disclosure of InterestNone Declared
Combination of CBT and rTMS: what are the advantages?
Authors: Kiss-Leizer M. , Horváth A. Á. , Kabella B. , Pogány L. , Lazáry J. 
Published: August 2024

IntroductionObsessive-Compulsive Disorder (OCD) and Major Depressive Disorder (MDD) are among the ten most disabling disorders, yet only 30-40% of people with the condition seek specialist care (WHO). Considered a relatively new tool in the treatment of OCD and MDD, repetitive transcranial magnetic stimulation (rTMS) was first used by our team 1 year ago. Based on current literature cognitive behavioural therapy (CBT) is effective in 60% of OCD cases, with MDD also having a good response rate of 50-60%. The efficacy of SSRI’s has been demonstrated, but side effects can have a negative impact on adherence in the long term. Prolonged use of certain drugs has adverse reactions that lead specifically to memory impairment, which compromises suitability for psychotherapy. The same problem applies to the use of electroconvulsive therapy (ECT) in a major depressive episode.ObjectivesOur aim was to study the efficacy of combining rTMS with CBT, to gather clinical experience on how these two different methods work in practice when combined.MethodsPatients diagnosed with therapy resistant MDD received rTMS treatment using 50Hz theta burst over 10 sessions. Therapy resistant OCD patients were treated by a 15 sessions rTMS using 1Hz single pulse. These rTMS sessions were combined with CBT, of which we would like to highlight two cases: one of them is a 34 years old woman, who has wide range of sexual, checking and contamination-related OCD symptoms and only received SSRI treatment so far. The other one is a 29 years old man, who suffers from religious obsessions, cleaning compulsions and other repetitive behaviours.Results
The positive effects of rTMS treatment on working memory functions, attentional capacity and cooperative skills without significant additive effects suggest exciting possibilities for combining the two treatments, thus the combined treatment has been tested in clinical practice. In our own patient care, an important experience was that patients were committed to the therapy, felt safe and, unlike with medications, did not have to worry about side effects. While medication and ECT can make psychotherapy more difficult in the long term - mainly because of memory problems - rTMS facilitates it. Patients appreciate that we approach their problems in a complex way, and they perceive that the combination of the two very different methods reflects professionalism. Our poster attempts to present the experience of combining rTMS and CBT from the therapist’s perspective through two case studies.ConclusionsBased on our experiences it is an effective approach to combine rTMS with CBT in therapy resistant MDD and OCD patients. In the light of these results the revision of the existing guidelines are considerable.AcknowledgementsThis study has been supported by the Human Resource Development Operating Programme 5.2.6 grant.Disclosure of InterestNone Declared
