Accumulating evidence shows that an increasing number of children and young people (CYP) are reporting mental health problems.

To investigate emotional disorders (anxiety or depression) among CYP in England between 2004 and 2017, and to identify which disorders and demographic groups have experienced the greatest increase.

Repeated cross-sectional, face-to-face study using data from the Mental Health of Children and Young People surveys conducted in 2004 and 2017, allowing use of nationally representative probability samples of CYP aged 5–16 years in England. A total of 13 561 CYP were included across both survey waves (6898 in 2004 and 6663 in 2017). We assessed the prevalence of any emotional, anxiety and depressive disorder assessed using the Development and Well-Being Assessment and classified according to ICD-10 criteria.

The prevalence of emotional disorders increased from 3.9% in 2004 to 6.0% in 2017, a relative increase of 63% (relative ratio 1.63, 95% CI 1.38, 1.91). This was largely driven by anxiety disorders, which increased from 3.5 to 5.4% (relative ratio 1.63, 95% CI 1.37, 1.93). The largest relative changes were for panic disorder, separation anxiety, social phobia and post-traumatic stress disorder. Changes were similar for different genders and socioeconomic groups, but differed by ethnicity: the most pronounced increase was among White CYP (relative ratio 1.88, 95% CI 1.59, 2.24), compared with no clear change for Black and minority ethnic CYP (relative ratio 0.85, 95% CI 0.52, 1.39). Comorbid psychiatric conditions were present in over a third of CYP with emotional disorders, with the most common being conduct disorder.

Between 2004 and 2017, the increase in emotional disorders among CYP in England was largely driven by anxiety disorders. Socioeconomic inequalities did not narrow. Disaggregating by ethnicity, change was evident only in White CYP, suggesting differential trends in either risk exposure, resilience or reporting by ethnicity.

Sustained alcohol intake, when combined with incomplete treatment, can result in chronic structural changes in the Central Nervous System, including generalized cortical and cerebellar atrophy, amnesic syndromes like Korsakoff’s syndrome, and white matter disorders such as Central Pontine Myelinolysis and Marchiafava-Bignami syndrome. It is crucial to prevent these complications due to their potential for irreversible and debilitating consequences. For Wernicke-Korsakoff syndrome, early recognition and thiamine administration for prevention are paramount, as it arises from thiamine deficiency due to malnutrition caused by persistent alcohol use. In the case of Central Pontine Myelinolysis, which is caused by abrupt fluctuations in serum osmolality, controlled sodium correction is essential.

Through a clinical case and a review of published literature, this study aims to reflect on the importance of preventing neurological injuries associated with chronic alcohol consumption, specifically Wernicke-Korsakoff Syndrome and Central Pontine Myelinolysis.

A literature review was conducted by searching for articles on PubMed using the terms “Alcohol Use Disorder,” “Wernicke-Korsakoff syndrome,” and “Central pontine myelinolysis.” A clinical case is presented, featuring a 50-year-old patient with alcohol use disorder who developed Wernicke-Korsakoff syndrome and Central Pontine Myelinolysis. Considering this case, we reflect on the primary approaches that could have been beneficial in preventing these complications and propose a straightforward method for doing so.

A 50-year-old patient presented with poor general condition, characterized by low weight, significant loss of strength in the limbs and arms, and incoherent speech with anterograde amnesia and confabulation. This condition had progressed to a point where the patient could no longer walk, perform basic self-care tasks such as bathing, dressing, and eating independently, underscoring the severity of his condition. The diagnoses of Wernicke-Korsakoff syndrome and Central Pontine Myelinolysis were established based on clinical manifestations and the presence of hyperintense lesions observed in the central pons on T2/FLAIR axial MRI scans. This clinical case highlights the importance of proper and precocious prevention of complications in patients with alcohol use disorder. The foremost step in preventing these complications is to treat alcohol dependence effectively, even when faced with patient resistance. It’s vital to remain vigilant about potential complications and implement suitable prophylactic measures.

The devastating effects of complications arising from Alcohol Use Disorder, such as Wernicke-Korsakoff syndrome and Central Pontine Myelinolysis, underscore the importance of enhanced attention that clinicians should provide when approaching these patients at all clinical interactions.

Commissioners play a central role in coordinating and planning CAMHS. However, there is little research on their experiences and approaches to understanding the needs of their populations. An improved understanding is likely to benefit the translation of research into practice, by ensuring research outputs meet the needs of key stakeholders and in optimising the sharing and use of data to improve services.

To better understand commissioners’ experiences of commissioning child and adolescent mental health services (CAMHS) and the challenges they face.

Between May to June 2023, we conducted twelve individual, semi-structured interviews with Integrated Care Board commissioners of CAMHS across England. We analysed data using framework analysis; a qualitative analysis method which involves systematically charting and organising data using a framework to generate themes.

We generated five core themes from the data: 1) ‘Reflections on role’ – how commissioners’ roles are informed by their background and ‘positioning’ within the system in which they work, 2) ‘Priorities and Tensions’ – the wider context in which commissioners work and how this may present challenges, 3) ‘Insights and evidence’– how commissioners develop an understanding of child mental health need and the different roles of quantitative and qualitative data, 4) ‘Children’s mental health in the limelight’ – commissioners’ perceptions of changes in child mental health in their populations, 5) ‘Responding to need’ – how commissioners are addressing the needs of their populations and the challenges they perceive.

CAMHS commissioners are negotiating a complex and changing political, social and economic environment with differing priorities and pressures. Commissioners draw heavily on insights from providers and their role is shifting towards managing relationships and bringing the system together. A key challenge is balancing investment in prevention/early intervention versus specialist services needed by children with more severe and complex problems.

Involuntary admission rates differ between gender across various countries. In several European Union countries, men are more frequently involuntarily admitted, while an opposite trend, associating women with involuntary care, has been observed in countries like Switzerland, Brazil, and China.

Considering the contradictory evidence about gender and involuntary care in the literature, we aim to analyze the gender patterns of involuntary care in Centro Hospitalar Médio Tejo’s Psychiatric Acute Unit, exploring the gender differences in diagnosis among involuntary patients.

We stored and analyzed the data using Microsoft Excel and IBM SPSS Statistics. We studied psychiatry admissions at Centro Hospitalar Médio Tejo, Portugal over 2 years. The Acute Psychiatric Unit, located within a general hospital, has 24 beds, and offers acute mental healthcare services to adults aged 18 and above, serving a coverage area of approximately 251,000 residents. As part of our data collection process for all admissions to the Acute Psychiatry Unit, we recorded information such as gender, age, diagnosis at discharge, treatment type (voluntary or involuntary), and length of stay.

From January 1, 2021, to December 31, 2022, there were 686 psychiatry admissions at Centro Hospitalar Médio Tejo, of which 125 (18,2%) were involuntary. The admission rates were approximately 136.6 per 100,000 people annually, with 24.9 being involuntary admissions per 100,000 people annually. In our analysis of involuntary admissions, women had a lower rate of such admissions, making up 6.4%, while men had a higher rate at 11.8%. No other gender identity was mentioned. Schizophrenia-related disorders were the primary cause for involuntary admissions for both genders, with 67.9% for men and 50% for women. Mood disorders were the second most common reason for involuntary admission, accounting for around 40.9% of cases for women and a significantly lower 16% for men. Involuntarily hospitalized patients exhibited longer lengths of stay independently of the gender. Men hospitalized involuntarily tended to be younger, whereas for women, involuntary hospitalizations were associated with older ages.

In conclusion, our study reveals gender differences in psychiatric involuntary admissions, with more men being involuntarily admitted than women. Schizophrenia group disorders were the most common diagnoses among male and female involuntary patients. Furthermore, all hospitalized women exhibited a higher prevalence of mood disorders, a trend that was more pronounced among those admitted involuntarily. These gender trends match the overall patterns seen in the epidemiology of schizophrenia and mood disorders. Additionally, women with schizophrenia generally exhibit better social functioning than men, which may explain the lower needs of involuntary hospitalization.

A 21-year-old male presented to the emergency room due to strange behavior

Show how emotionally intense events can be a stress factor leading to dissociative or psychotic symptoms.

Case report and literature review

The patient is in Spain after having attended the meeting with the Pope at the World Youth Day in Portugal. He is an engineering student who, in the week prior to the trip, had high levels of stress related to exam time. He also explained that he had recently had conflicts with his partner. In the psychocopathological examination of the patient, a global insomnia of 3 days of duration stands out. In addition, a disorganized and disjointed speech focused on high concern that something bad could happen to his family and partner. In the interview he appears restless, nervous, with a perplexed contact. The patient’s companion says that he has been very worried and obsessed about his relationship with his partner, with constant doubts about asking her to marry him. It is decided to start olanzapine, receiving up to 15 mg per day. In the following interviews he shows better contact and a more organized speech.

It is known that emotionally intense situations can be a trigger for the development of psychotic symptoms. There are different manifestations of these stressful situations such as physical symptoms like fainting or but mental symptoms are also described such as dissociative amnesias, or less frequent as in this case psychotic symptoms. They are usually of sudden onset and early remission with good response to anxiolytics or antipsychotics.

Mental health problems are common in children and young people (CYP) in England, yet evidence suggests high levels of unmet need in this group. Understanding of the determinants of mental health-related service contact is needed to identify gaps in service provision and areas for targeted intervention to improve access.

To determine the relationship between CYP characteristics and mental health-related support and service contact in England.

A secondary analysis of the 2017 NHS Digital Mental Health of Children and Young People (MHCYP-2017) cross-sectional survey dataset was performed. MHCYP-2017 was a national survey investigating the mental health of CYP using a stratified multistage random probability sampling approach, providing the official national statistics for England. Multi-informant data were collected through a combination of questionnaires and interviews. Expert clinical rating took place to formally identify the presence of mental disorders, according to established diagnostic criteria. This secondary analysis describes mental health-related support and service contact amongst 6681 participants aged 5-16 recruited to the MHCYP-2017 study. A range of socio-demographic and clinical characteristics were analysed as explanatory variables and their relationships with different types of support/service contact were examined through multivariable multinomial logistic regression. Analyses were stratified by age group: 5-10- and 11-16-year-olds.

Overall, around 25% of parents reported CYP mental health-related contact with one or more types of support/service in the past 12 months due to concerns regarding CYP “emotions, behaviour, concentration or difficulties in getting along with people”. Age stratified multivariable analyses revealed several statistically significant associations between participant socio-demographic/clinical characteristics and mental health-related support and service contact, independent of CYP mental health status and parental perception of difficulties. These associations were not necessarily consistent across mental health support categories, suggesting that several of the measured characteristics have differential relationships with different types of support and service contact. Whilst there were some differences between the 5-10 and 11-16 age groups, similar associations were seen for many of the explanatory variables. Socioeconomically disadvantaged and black and minority ethnic CYP were less likely to have had professional contact for mental health problems.

There may be higher levels of unmet need in socioeconomically disadvantaged and black and minority ethnic CYP, warranting further investigation and efforts to address inequalities. Further longitudinal studies are needed to elucidate causal associations and mechanisms underlying these observations.

Obsessive-compulsive disorder (OCD) is a mental disorder in which patients who suffer from it have repetitive and undesirable thoughts, feelings, ideas, sensations (obsessions) and behaviors that drive them to do something over and over again (compulsions).

Often the person tries to get rid of the obsessive thoughts through compulsions, but this only provides short-term relief. Not carrying out the obsessive rituals can cause enormous anxiety and suffering.

To describe a 23-year-old male patient, who suffers from anxiety and mood symptoms, reacts to ego-dystonic obsessive ideas and sexual content, of months of evolution, and who manages to calm down through compulsive masturbation or watching sexual videos on the internet. All this clinic negatively interferes with their quality of life, asking the patient for medical help to calm these ideas.

We carried out a review in Pubmed with the terms Antiandrogens and TOC, in order to make a better description of the clinical case.

After several treatment attempts (Sertraline, Paroxetine, Clomipramine, Clomipramine + SSRI), reaching maximum doses according to clinical guidelines, and with poor therapeutic response, it was decided to discuss the case with the endocrinology department of our hospital, deciding to start treatment with antiandrogens, in order to alleviate the persistent intrusive ideas of a sexual nature. The administration of antiandrogens in men can cause a decrease or increase in the development or involution of secondary sexual characteristics in men, reducing the activity or function of accessory sexual organs, and hyposexuality, with decreased sexual desire or libido.

After several weeks, there was improvement in the obsessive symptoms with a decrease in compulsive rituals. However, after the 3rd mo, some symptoms reappeared, but not with the same severity and intensity as before treatment. In addition, we cannot ignore the adverse effects that have occurred, such as involution of secondary sexual characteristics. However, and taking into account the negative repercussion that this clinic had on the patient’s quality of life, the benefit obtained exceeded the risk, having noted clear improvement with this therapy, and maintaining evolutionary controls by both psychiatry and endocrinology.

Patients suffering from obsessive-compulsive disorder can be effectively treated with anti-androgenic pharmacological agents with various modes of action. The most effective group of such agents is the long-acting analogues of the gonadotropin-releasing hormone. The objective of this review is to elucidate the possibility of using such powerful anti-androgenic agents in the treatment of obsessive-compulsive disorder.

CD is characterized by at least three features: its duration is prolonged, it does not resolve spontaneously and it is rarely completely cured. Approximately 10-15% of young people have CD. Adolescents with CD often have emotional and behavioral problems.

To assess risk factors, derived psychiatric pathologies and coping strategies for a CD diagnosis in adolescence.

An extensive literature review was carried out on the subject in question, extracting information mainly from scientific articles, manuals and books.

The main risk factors are those related with the CD in question, physical sequelae, the need for long-term hospital admissions or the use of drugs whose side effects include affective or behavioral symptoms; those related to the personality traits of the affected child or adolescent. In addition, as far as the family is concerned, the presence of a low level of education, lack of support or communication, as well as the presence of psychiatric disorders or serious medical conditions in parents. Among the most frequent psychiatric disorders associated with CD are affective and anxiety disorders, adaptive disorders, somatoform disorders, eating disorders and behavioral disorders. Whatever the CD is, it generates high levels of stress and uncertainty in the patient and family, which must be dealt together from a flexible perspective, allowing child or adolescent to adapt to the changes, reorganize and facing them with adaptive patterns of behavior. For this, it will be essential to have adequate social and family support with relational style based on communication, trust and acceptance.

In general, both adolescents with CD and their families have an adequate capacity to adapt to the repercussions and effects derived from the disease. Nevertheless, in case of possible emotional difficulties that may appear, a comprehensive and individualized approach to these adolescents and their families is necessary to provide them resources and coping strategies in different areas and contexts in which the disease debuts.The comprehensive therapeutic approach will consist of interventions at the individual and family level. Among the main objectives of these interventions are to achieve acceptance and adaptation to CD provinding adequate psychosocial support to enable them to cope with CD in the best possible way and to detect and address the emotional implications, even coexisting psychopathology.

We have investigated the relationship between the Psychosomatic Classification method (Marty) and the Rorschach Test, with respect to the diagnosis of psychosomatic disorders, within the framework of the degree of mentalization measured by both.

A) To verify statistical coincidence with respect to the degree of mentalization (risk of generating psychosomatic disorders in a subject) between the Rorschach Test and the diagnostic technique Psychosomatic Classification, by P. Marty. B) To test the hypothesis: Patients diagnosed with infertility, whose degree of mentalization is good, will have a greater probability of achieving a successful pregnancy throught Assisted Reproduction Techniques.

Two evaluation tools were used: a) Psychosomatic Classification based on the criteria established by this diagnostic method; b) The Rorschach test (based on the evaluation of 29 indicators, selected according to their greater relevance in the generation of somatic symptoms).

A sample of 120 patients (women) diagnosed infertility at the Assisted Reproduction Unit (U.R.A.) at Hospital Universitario 12 de Octubre in Madrid was recruited. The method of ‘statistical correlation of coincidence’ between the results of the two diagnostic instruments used was used. Once both tests had been assessed by the “inter-judge” method and the quantitative values of the selected items had been weighted, the KAPPA statistical method was applied to establish the “correlation of coincidence” between the results of the two assessment instruments.

Considering that the KAPPA method takes values between “0" and ”1" and that between 0.6 and 0.8 the agreement or coincidence is considered good, and above 0.8 very good, the result applied to the hypothesis is 0’76 (’good’).

A) Using the Rorschach Test and P. Marty’s Psychosomatic Classification in a complementary manner, these two instruments together provide high reliability, with respect to the degree of mentalization (a subject’s risk of suffering psychosomatic disorders). B) The degree of mentalization has a significant impact on the success or failure in the application of Assisted Reproduction Techniques in infertile women.

In this research the Paris School (I.P.S.O.), by P. Marty, is chosen as the theoretical and clinical basis of Psychosomatics. We work with the degree of mentalization (good, bad and uncertain) -obtained through Marty’s Psychosomatic Classification-, as a previous diagnosis and prognosis of 120 infertile women undergoing treatment at the Assisted Reproduction Unit (ARU) at Hospital Universitario 12 de Octubre in Madrid.

a) To analyse the statistical coincidence between female infertility, stress and alexithymia syndrome. b) To verify the differences between psychosomatic disorders and other somatoform symptoms and syndromes (conversive and hypochondriac). c) To test the following hypothesis: subjects whose degree of mentalization is deficient, present high degree of alexithymia and stress.

120 infertile women undergoing treatment with Assisted Reproduction Techniques were examined by means of psychodiagnostic tests.

Diagnostic tools: P. Mary’s Psychosomatic Classification (P.C.) (semi-structured interview), as a means of diagnosing the degree of mentalization; T.A.S. (Toronto Alexithymia Scale); Battery of stress measurement questionnaires (H.A.D., PANAS. IRE, MCMQ).

The correlation of coincidence between the results of C.P. and the different Alexithymia and Stress questionnaires with the independent variable (success or failure of pregnancy in the selected subjects) has been studied, applying Spearman’s Correlation Coefficient.

With respect to what was obtained in the Psychosomatic Classification:

- T.A.S. questionnaire yields a coefficient of [-0.48]. Therefore, there is a negative correlation between the degree of mentalization and the presence of alexithymia; in other words, as the degree of mentalization increases, the degree of alexithymia decreases and vice versa;

- There is positive correlation [0.39] between the results of Mentalization (Psychosomatic Classification) and the degree of stress; therefore, the existence of stress does not prevent better mentalization.

The present research concludes: a) that people at risk for psychosomatic disorders have high scores on “alexithymia”; b) that patients at high risk for psychosomatic disorders do not necessarily suffer from “stress” situations; c) that there are many indicators in behavior and psychological functioning that differentiate psychosomatic disorders from conversive and hypochondriac disorders - both in their etiology and their development; d) there is a statistical correlation between female infertility and alexithymia; e) there is no statistical correlation between female infertility and stress.

According to the World Health Organization (2016), adolescence is one of the most important transitional steps in the life of a human being, recognized by an accelerated rate of growth and changes in behavior. Adolescents from Colombia have reached this step, immersed in a context with a history of social, interpersonal and economic violence. In this sense, study of constructs such as empathy and aggressive behaviors are crucial to appease a healthy school coexistence and thus, contribute to a peace cultur

Analyze the relationship between empathy and aggressive levels from adolescents.

This study was done through a cross-sectional study of correlational scope in 240 (N= 240) students. The Prosocial Behavior Questionnaire developed by Martorell and Gonzalez (1922) and the Aggressive questionnaire, developed by Buss and Perry (1992) were applied. The first one was used to measure empathy and the latter to appraise aggressiveness.

There was evidenced of adequate levels of empathy and a great percentage of medium levels of verbal and physical aggressiveness. (Graph 1). In addition, there was a significant statistical correlation of negative magnitude between these variables (Table 1).

It was concluded that the higher the optimal levels of empathy, the lower the aggressive behavior presented by teenagers.

No significant relationships.

The Personal and Social Performance (PSP) scale is a reliable and valid instrument that utilizes objective parameters for assessment of social functioning in patients with schizophrenia. The aim of this study was to determine the validity and reliability of the French version of PSP in a population of French schizophrenic patients.

Patients with DSM-IV diagnoses of schizophrenia and schizoaffective disorder were recruited and assessed in a cross-sectional design using the PSP, GAF, SOFS, PANSS, CGI severity. Internal consistency for the PSP was obtained and convergent validity was assessed using correlations between PSP, GAF and PANSS factors. Inter-rater reliability was evaluated with intra class correlation coefficient (ICC).

147 in and out patients, at 5 French sites participated in this study. The Cronbach's alpha coefficient of the PSP was good (alpha=0.77). The PSP showed very good inter rater reliability (ICC = 0.90). Pearson correlation coefficient for association between PSP and GAF (r=0.85) and PSP and SOFS (r=- 0.78).are high proving good convergent validity for PSP. Pearson correlation coefficients are moderate when PSP is correlated with 4 of the five PANSS sub factors (r from -0.43 to -0.48). The anxious and depression factor (r=-0.17) showed low correlation with PSP. Spearman Rank correlation coefficient between PSP and CGI severity was r=-0.72.

Our results demonstrate that the PSP scale is a reliable and valid instrument for assessing social functioning of patients with schizophrenia during the course of treatment as well as in acute state.

To evaluate social and occupational functioning in patients in partial remission (PR) compared with patients in complete remission (CR) of a major depressive disorder (MDD) episode.

This is a six-month prospective study. PR was defined as a score more than 7 and less or equal to 15 in the Hamilton Depression Rating Scale, and CR as less or equal to 7. All patients had been on acute antidepressant treatment during the previous three months and no longer met criteria for MDD. Functioning was assessed by the Social and Occupational Functioning Assessment Scale (SOFAS).

Mean (S.D.) patient age was 50.5 (14.5) years (N = 292) and 77% were female. At baseline, partial remitters showed greater impairment in social and occupational functioning than complete remitters (62.8 [12.6] versus 80.4 [10.5], respectively; P < .0001). After six months, only 47% PR versus 77% CR reached normal functioning, and SOFAS ratings for PR were below normal range (76.2 [12.3] PR versus 84.6 [9.4] CR; P < .0001). PR reported three times more days absent from work due to sickness than CR (63 days versus 20 days; P < .001).

We conclude that PR of an MDD episode is associated with significant functional impairment that persists even after nine months of antidepressant treatment. Our results underline the importance of treating the patient until achieving full remission.

The brain-derived neurotrophic factor (BDNF) is a neurotrophin fundamentally involved in the differentiation and growth during brain development. BDNF has pathogenically been linked to the schizophrenia neurodevelopmental hypothesis. Several studies have found lower BDNF blood levels in chronic schizophrenia than controls. Few studies suggest that BDNF levels in first-episode psychosis (FEP) are lower than in healthy controls (HC).

Comparing serum BDNF levels in a group of antipsychotic-naive FEP with HC and determining the serum BDNF pattern during the first year illness evolution.

Serum BDNF levels at admission of 28 inpatients with FEP were compared with 28 age/gender matched HC. BDNF was also measured at discharge, three, six, nine and twelve months. After discharge, antipsychotics were gradually decreased. Results are presented as mean±sd. and BDNF levels in ng./ml.

At admission, patients BDNF levels were significantly lower than controls (18.06±4.06 vs 26.55±3.22, p>0.001). At discharge FEP levels increase until HC levels without significant differences between gropus (25.95±3.93 vs 26.55±3.22, p=0.539). Upon the following determinations, BDNF FEP levels progressively decreased, reaching the admission values, and being significantly lower than the controls and that levels at discharge (patients: three months: 19.68±3.88; six months: 19.02±4.13; nine months: 17.64±5.24; twelve months: 17.51±3.45 vs controls: 26.55±3.22, all p>0.001).

Our results confirm the studies that found lower BDNF levels in chronic schizophrenia. Serum BDNF levels could be considered as a biological marker of treatment and evolution of FEP. Further studies with FEP patients with and without treatment are warranted.

CYP2D6 and CYP2C19 are involved in the metabolism of widely used antidepressants and other drugs with psychotropic activity. They also participate in the metabolism of endogenous substrates, and are expressed in the brain.

This study examined, for the first time, whether a high CYP2D6-CYP2C19 metabolic capacity combination increases the likelihood of suicidal intent severity in a large study cohort.

Survivors of a suicide attempt (n=587; 86.8% women) were genotyped for CYP2C19 (*2, *17) and CYP2D6 (*3, *4, *4xN, *5, *6, *10, wtxN) genetic variation and evaluated with the Beck Suicide Intent Scale (SIS).

Patients with a high CYP2D6-CYP2C19 metabolic capacity showed an increased risk for a severe suicide attempt (P<0.01) as measured by the SIS-objective circumstance subscale (odds ratio (OR)=1.37; 95% confidence interval (CI)=1.05-1.78; P=0.02). Importantly, the risk was greater in those without a family history of suicide (OR=1.82; CI=1.19-2.77; P=0.002).

Further research is warranted to evaluate whether the observed relationship is mediated by the role of CYP2D6 and CYP2C19 involvement in the endogenous physiology or drug metabolism or both.

Tapentadol is a centrally-acting synthetic analgesic which acts as a mu-opioid receptor agonist as well as a norepinephrine re-uptake inhibitor. It is use to treat cronic pain. Most prevalence adverse effects are gastrointestinal and nervous symptoms. Furthermore, it has objectified, with less frequency, psychiatric disturbances.

To analyse the relationship between a maniac episode and tapentadol.

Forty-nine-year-old female, with personal history of dyslipidemia and lumbar herniated discs in L4-L5, L5-S1, in treatment with tapentadol 200 mg/day for 20 days and no past psychiatric history. She was admitted to the Psychiatry Department due to a maniac episode, with desinhibition, pressure and loud speech, euphoria, megalomaniac delusion and sleep disturbance for the last 10 days. Young Mania Rating Scale (YMRS) was 36 points. Olanzapina 15 mg/day was introduced and tapentadol was removed. Symptoms remitted quickly and 6 days later, at discharge, YMRS was 4 points. One year later, the patient continued to be asymptomatic.

Opioids can produce psychiatric disorders like hallucination, sleep disorders, depressed mood, disorientation, agitation, nervousness, restlessness, euphoric mood. Secondary mania to tapentadol mechanism is unknown, but having opiate cases described, it is possible to attribute this episode to tapentadol.

– Secondary mania is associated with various medical conditions, including vitamin B12 deficiency, brain injury, HIV infection and drugs such as alcohol, caffeine, sympathomimetics, steroids, bupropion, isoniazid, clarithromycin and opioids.

– Further research is required to determine if the maniac episode was only isolated by the tapentadol or it is the beginning of a bipolar disorder.
