Síntomas maníacos en encefalitis autoinmune por anticuerpos contra mGluR5: a propósito de un caso / Maniac symptoms in autoimmune encephalitis due to mGluR5 antibodies: Presentation of a case

La encefalitis autoinmune es una entidad heterogénea en cuanto a su presentación clínica y pronóstico. Es frecuente que este cuadro presente síntomas psiquiátricos por lo que es habitual la intervención de los servicios de psiquiatría tanto en el proceso diagnóstico como en el manejo sintomático. El curso de la enfermedad suele ser agudo o rápidamente progresivo motivo por el cual es esencial la detección precoz de esta enfermedad con el fin de realizar las exploraciones complementarias y el tratamiento etiológico. Describimos el caso de un varón de 49 años, sin antecedentes psiquiátricos que presenta sintomatología maniforme en urgencias pero que a las pocas horas de ingresar en la unidad de agudos presenta disminución del nivel de consciencia y fiebre. Las exploraciones complementarias permiten orientarlo como encefalitis autoinmune por anticuerpos contra el receptor metabotrópico de glutamato 5. La psiquiatría de interconsulta participa en el manejo sintomático del paciente

Autoimmune encephalitis is a heterogeneous entity in terms of its symptoms and prognosis. As the clinical presentation frequently includes psychiatric symptoms, the intervention of psychiatric services is usual in the diagnostic process, as well as in the management of the symptoms. The course of the disease is usually acute or rapidly progressive, making the early detection of this disease essential in patients in order to perform the complementary tests and to treat the origin. The case is presented of a 49 year-old man, with no psychiatric history, who presents with maniac symptoms in the emergency room. A few hours after being admitted to the inpatient unit he presents with decrease in consciousness level and fever. Complementary tests led to the diagnosis of autoimmune encephalitis with antibodies against the metabotropic receptor of glutamate 5. The psychiatric approach for symptomatic treatment was made by joint consultation

El suicidio en jóvenes en España: cifras y posibles causas. Análisis de los últimos datos disponibles / Suicide among young people in Spain: facts and possible causes. An analysis of latest data available

El suicidio es la tercera causa de muerte en el grupo de edad de entre los 15 a los 29 años, superado sólo por las causas externas de mortalidad y los tumores, de acuerdo con el Instituto Nacional de Estadística. En los últimos datos disponibles se pone de manifiesto que 310 niños y jóvenes menores de 30 años se quitaron la vida, lo que supone un 7.77% del total de víctimas del suicidio. El presente artículo, pretende describir profusamente el estado de la cuestión a la luz de los datos disponibles en la literatura, partiendo del panorama general a nivel mundial. Se discuten las causas que pueden desembocar en este tipo de actos, señalándose la presencia de trastornos psicológicos, variables concretas de personalidad, la alta carga de estrés emocional y, especialmente, el bullying, últimamente desplazado por nuevas vertientes como el bullying electrónico o el sexting

Suicide is the third leading cause of death in the age group between 15 to 29 years, surpassed only by external causes of death and tumors according to the National Institute of Statistics. The latest data available shows that 310 children and young people under 30 took their own lives, which represents 7.77% of all suicide victims. This article aims to extensively describe the state of the art from the data available in the literature, based on the overview worldwide. The causes that can lead to such acts are discussed, indicating the presence of psychological disorders, specific personality variables, the high burden of emotional stress or bullying, lately displaced by new variants such as cyberbullying or sexting

The interplay of childhood behavior problems and IQ in the development of later schizophrenia and affective psychoses.

Schizophrenia and affective psychoses are both associated with impaired social functioning, but the extent to which childhood behavioral impairments are present prior to onset of illness is less well studied. Moreover, the concurrent relationship of childhood behavior problems and premorbid IQ with subsequent psychotic disorder has not been established. We investigated whether childhood behavior problems are associated with increased risk for adult schizophrenia or affective psychosis, independently and in combination with IQ. The study included individuals with schizophrenia (N=47), affective psychoses (N=45) and non-psychotic controls (N=1496) from the New England Family Study. Behavior problems were prospectively assessed from standardized clinician observations at ages 4 and 7. IQ was assessed with the Stanford-Binet at age 4 and the Wechsler Intelligence Scale for Children at age 7. We found externalizing problems at age 4 and externalizing and internalizing problems at age 7 were associated with later schizophrenia, and both internalizing and externalizing problems at ages 4 and 7 were associated with later development of affective psychoses. Lower IQ at ages 4 and 7 was associated with schizophrenia, while lower IQ was associated with affective psychoses at age 7 only. Examined simultaneously, both lower IQ and behavior problems remained associated with risk of schizophrenia, while only behavior problems remained associated with affective psychoses. Behavior problems appear to be a general marker of risk of adult psychotic disorder, while lower childhood IQ is more specific to risk of schizophrenia. Future research should clarify the premorbid evolution of behavior and cognitive problems into adult psychosis.

Lifetime psychopathological dimensions, cognitive impairment and functional outcome in psychosis.

Psychopathological symptoms and cognitive impairment are related to psychosocial functioning. However, the nature of the association of cognitive impairment with psychosocial functioning still remains under scrutiny. We aimed to examine the relationships of premorbid adjustment, lifetime psychopathological dimensions, and cognitive performance with the typical level of psychosocial functioning during the previous year. We assessed ninety patients with schizophrenia spectrum disorders and affective disorders with psychotic symptoms to collect data on premorbid adjustment, lifetime psychopathological dimensions, cognitive performance and psychosocial functioning. Sixty-five healthy volunteers were included as controls. Pearson's correlations and hierarchical regression analyses were performed to ascertain to what extent the aforementioned variables predicted psychosocial functioning. Functional domains were significantly correlated with most of the premorbid features, lifetime psychopathological dimensions and cognitive domains. However, lifetime negative symptoms were the best predictors of psychosocial functioning in the hierarchical regression analyses (explaining between 47 and 64% of the variance). For psychosocial outcome in patients with psychoses, lifetime negative symptoms showed a stronger predictive validity than cognitive impairment or premorbid adjustment.

Categorical and dimensional psychopathology in Dutch and US offspring of parents with bipolar disorder: A preliminary cross-national comparison.

OBJECTIVE: Accumulating evidence suggests cross-national differences in adults with bipolar disorder (BD), but also in the susceptibility of their offspring (bipolar offspring). This study aims to explore and clarify cross-national variation in the prevalence of categorical and dimensional psychopathology between bipolar offspring in the US and The Netherlands. METHODS: We compared levels of psychopathology in offspring of the Pittsburgh Bipolar Offspring Study (n=224) and the Dutch Bipolar Offspring Study (n=136) (age 10-18). Categorical psychopathology was ascertained through interviews using the Schedule for Affective Disorders and Schizophrenia for School Age Children (K-SADS-PL), dimensional psychopathology by parental reports using the Child Behavior Checklist (CBCL). RESULTS: Higher rates of categorical psychopathology were observed in the US versus the Dutch samples (66% versus 44%). We found no differences in the overall prevalence of mood disorders, including BD-I or -II, but more comorbidity in mood disorders in US versus Dutch offspring (80% versus 34%). The strongest predictors of categorical psychopathology were maternal BD (OR: 1.72, p<.05), older age of the offspring (OR: 1.19, p<.05), and country of origin (US; OR: 2.17, p<.001). Regarding comorbidity, only country of origin (OR: 7.84, p<.001) was a significant predictor. In general, we found no differences in dimensional psychopathology based on CBCL reports. LIMITATIONS: Preliminary measure of inter-site reliability. CONCLUSIONS: We found cross-national differences in prevalence of categorical diagnoses of non-mood disorders in bipolar offspring, but not in mood disorder diagnoses nor in parent-reported dimensional psychopathology. Cross-national variation was only partially explained by between-sample differences. Cultural and methodological explanations for these findings warrant further study.

Uncovering the Neural Bases of Cognitive and Affective Empathy Deficits in Alzheimer's Disease and the Behavioral-Variant of Frontotemporal Dementia.

Loss of empathy is a core presenting feature of the behavioral-variant of frontotemporal dementia (bvFTD), resulting in socioemotional difficulties and behavioral transgressions. In contrast, interpersonal functioning remains relatively intact in Alzheimer's disease (AD), despite marked cognitive decline. The neural substrates mediating these patterns of loss and sparing in social functioning remain unclear, yet are relevant for our understanding of the social brain. We investigated cognitive versus affective aspects of empathy using the Interpersonal Reactivity Index (IRI) in 25 AD and 24 bvFTD patients and contrasted their performance with 22 age- and education-matched controls. Cognitive empathy was comparably compromised in AD and bvFTD, whereas affective empathy was impaired exclusively in bvFTD. While controlling for overall cognitive dysfunction ameliorated perspective-taking deficits in AD, empathy loss persisted across cognitive and affective domains in bvFTD. Voxel-based morphometry analyses revealed divergent neural substrates of empathy loss in each patient group. Perspective-taking deficits correlated with predominantly left-sided temporoparietal atrophy in AD, whereas widespread bilateral frontoinsular, temporal, parietal, and occipital atrophy was implicated in bvFTD. Reduced empathic concern in bvFTD was associated with atrophy in the left orbitofrontal, inferior frontal, and insular cortices, and the bilateral mid-cingulate gyrus. Our findings suggest that social cognitive deficits in AD arise largely as a consequence of global cognitive dysfunction, rather than a loss of empathy per se. In contrast, loss of empathy in bvFTD reflects the deterioration of a distributed network of frontoinsular and temporal structures that appear crucial for monitoring and processing social information.

[Can men be included in the population subjected to puerperal psychosis? A case report]. / Psychose puerpérale chez l'homme : une entité diagnostique ?

INTRODUCTION: Puerperal psychosis (PP) is a psychiatric disorder that occurs in 1 out of 1000 pregnancies. Well known since antiquity, its symptoms have often been described in mothers, but few studies have successfully investigated a related disorder in fathers. The characteristic of this pathology is more related to its appearance than to its semiological description which is why its nosographic place is always discussed. The objective here is to focus on the definition of PP and to suggest an entity for both genders. CASE REPORT: Our case report focused on the clinical description of an eighteen-year-old man suffering from an acute psychosis episode that occurred around the birth of his first child. Delusion followed a sudden decline in mood that lasted for a short period of time during the course of the third trimester of his wife's pregnancy. The delirium was rich with auditory and cenesthesic hallucinations, pregnancy and birth denial, feeling movements and hearing voices in his stomach. The symptoms disappeared after one month of treatment via an antipsychotic drug, risperidone. CONCLUSION: We can confirm that the symptomatic description of the disorder in this patient fits the classical descriptions of PP. Two elements make the PP different from other acute psychoses: the context of pregnancy and delirium focused on the child which can lead to a child murder. The absence of a framework precisely defining the PP does not improve its prevention and can lead to legal attitudes rather than medical care. Men suffering from acute psychosis in a context of pregnancy are submitted to the same risks as women. It is necessary to emphasize descriptions of PP in men to redefine the disease and consider that this entity involves both men and women.

Cushing Disease Presenting as Primary Psychiatric Illness: A Case Report and Literature Review.

We report the case of a woman with long-standing refractory depression and psychotic features who was eventually diagnosed with Cushing disease. After surgical treatment of a pituitary adenoma, she experienced gradual psychiatric recovery and was eventually able to discontinue all psychotropic medication. We review the psychiatric components of Cushing disease, implications of psychiatric illnesses for the treatment and prognosis of Cushing disease, and potential pathophysiological mechanisms linking glucocorticoid excess to psychiatric illness.

[Case of graves' disease with remarkable psychiatric symptoms].

A 42-year-old woman visited our hospital with palpitations, excessive sweating, and finger tremors in March 2011. She was diagnosed with Graves' disease based on the following test results: thyroid stimulating hormone < 0.01 µU/ml, free thyroxine 6.15 ng/ml, and thyrotropin receptor antibody 7.8 U/ml. Treatment with methimazole 30 mg and propranolol 30 mg was started, and her thyroid function showed improvement. However, significant manic symptoms, irritability, hallucinations, and delusions were noted, and she was hospitalized for her own protection in May 2011. Although treatment with aripiprazole 24 mg and lithium 400 mg was started, the hallucinatory and delusional symptoms persisted, necessitating adjustment of the antipsychotics. Her psychiatric symptoms showed amelioration in July 2011 after improvement in her thyroid function, and she was discharged from our hospital. After discharge, her thyroid function remained normal with methimazole 10 mg, and administration of the antipsychotics was discontinued. Affective psychotic symptoms such as altered mood and activity are frequently observed in cases with Graves' disease, but there have been few reports describing cases with full-blown psychiatric disorders manifesting with features such as hallucinations and delusions as the chief symptoms requiring hospitalized treatment, as in the present case. In symptomatic psychosis associated with Graves' disease, prolonged psychiatric symptoms might develop, and close cooperation with psychiatrists is thus important.

Prenatal maternal immune disruption and sex-dependent risk for psychoses.

BACKGROUND: Previous studies suggest that abnormalities in maternal immune activity during pregnancy alter the offspring's brain development and are associated with increased risk for schizophrenia (SCZ) dependent on sex. METHOD: Using a nested case-control design and prospectively collected prenatal maternal sera from which interleukin (IL)-1ß, IL-8, IL-6, tumor necrosis factor (TNF)-α and IL-10 were assayed, we investigated sex-dependent associations between these cytokines and 88 psychotic cases [SCZ = 44; affective psychoses (AP) = 44] and 100 healthy controls from a pregnancy cohort followed for > 40 years. Analyses included sex-stratified non-parametric tests adjusted for multiple comparisons to screen cytokines associated with SCZ risk, followed by deviant subgroup analyses using generalized estimating equation (GEE) models. RESULTS: There were higher prenatal IL-6 levels among male SCZ than male controls, and lower TNF-α levels among female SCZ than female controls. The results were supported by deviant subgroup analyses with significantly more SCZ males with high IL-6 levels (>highest quartile) compared with controls [odd ratio (OR)75 = 3.33, 95% confidence interval (CI) 1.13-9.82], and greater prevalence of low TNF-α levels (

A young woman presenting with psychotic and mood symptoms from anti-N-methyl-D-aspartate receptor (NMDA-R) encephalitis: an emerging diagnosis.

Anti-N-methyl-D-aspartate receptor (NMDA-R) encephalitis, first characterized in 2005, is a neurological disease with prominent psychiatric features that frequently involves the consultation of psychiatrists. Since its discovery, the rate of diagnosis of new cases has increased rapidly and several epidemiological studies now confirm that NMDA-R encephalitis may be as common as many other prominent infectious etiologies of encephalitis. We describe a case of a young woman presenting initially with psychotic and mood symptoms who was found to have anti-NMDA-R encephalitis. We further provide details of her treatment and prolonged recovery process after hospital discharge with a review of the literature and discussion of the epidemiology, symptomology, diagnosis, and management of both the neurologic and psychiatric manifestations of this condition. Last, we contextualize the importance of anti-NMDA-R encephalitis for psychiatrists, highlighting the role for psychiatrists in establishing the initial diagnosis as well as in providing ongoing psychiatric care.

Decreased birth weight in psychosis: influence of prenatal exposure to serologically determined influenza and hypoxia.

BACKGROUND: Decreased birth weight (BW) is associated with later psychosis, but the sources of decreased BW for those at risk for psychosis remain unclear. AIM: To determine whether fetal exposure to influenza and/or hypoxia accounts for BW decreases among psychotic cases and controls. METHOD: Subjects were 111 cases diagnosed with schizophrenia or affective psychosis and 333 matched controls from the Collaborative Perinatal Project. Psychiatric diagnoses were ascertained from medical records. Influenza and hypoxia were determined from maternal and cord sera collected at birth. RESULTS: Cases exposed to severe fetal hypoxia or influenza had significantly lower BW compared with unexposed cases and controls, regardless of exposure status. No significant differences in BW were observed among controls based on exposure status. CONCLUSIONS: Decreased BW appears to be a risk factor for psychosis only in the presence of other teratogens. Liability to psychosis likely renders fetuses vulnerable to decreased fetal growth in response to hypoxia and influenza.

Effectiveness of psychological interventions in chronic stage of stroke: a systematic review.

OBJECTIVE: To examine the effectiveness of interventions for psychological issues faced by individuals post stroke when initiated in the chronic stage of stroke. METHOD: MEDLINE, CINAHL, EMBASE, and Scopus databases were searched from 1980 to July 2012. A study was included if (1) the study was a randomized controlled trial (RCT); (2) at least 50% of individuals in the study were entered into the study at over 6 months post stroke; (3) the study examined the effect of an intervention on psychological functioning; and (4) study participants were ≥ 18 years of age. Similar interventions were grouped and results summarized. Data on the study design, participant characteristics, interventions, outcomes, and adverse events were extracted from each of the selected studies. RESULTS: Nine RCTs met inclusion criteria. All 9 studies examined effectiveness on mood and 3 on adjustment. Repetitive transcranial magnetic stimulation had the strongest evidence of effectiveness in improving mood followed by pharmacotherapy; whereas exercise appeared to be effective in improving adjustment and coping among individuals in the chronic stage of stroke. CONCLUSION: Overall, interventions provided in the chronic stage of stroke appear to be effective in improving mood and adjustment up to 3 months post intervention. The use of multidisciplinary interventions and acceptance models may be important in the overall adjustment process.

Childhood infection and adult schizophrenia: a meta-analysis of population-based studies.

OBJECTIVE: To determine whether exposures to infectious illness during childhood involving the CNS or elsewhere is associated with adult schizophrenia or other psychoses. METHOD: Systematic review and meta-analysis of published literature identified by electronic and manual search meeting three inclusion criteria: population-base, objective assessment of childhood infection at the individual level, standard definition of adult psychotic outcomes. We calculated risk ratio for all CNS infection, and separately for viral and bacterial infection in relation to non-affective psychosis and schizophrenia, which was combined in meta-analysis. RESULTS: Seven studies were included. Meta-analysis involving 2424 cases and over 1.2 million controls showed CNS viral infection was associated with nearly two-fold increased risk of adult non-affective psychosis (risk ratio 1.70; 95% CI 1.13-2.55; p=0.01). There was no significant heterogeneity between studies (p=0.26; I(2)=20%). Separate meta-analysis involving 1035 cases and over 1.2 million controls suggested all childhood CNS infections, particularly viral infections, may be associated with nearly two-fold risk of adult schizophrenia. However, there was evidence of some heterogeneity between these studies (p=0.07; I(2)=70%). CNS bacterial infections were not associated with risk of psychosis. Data on childhood infections with no obvious involvement of the CNS is insufficient. CONCLUSIONS: These findings indicate childhood CNS viral infections increase the risk of adult psychotic illness. Possible mechanisms may include both direct effects of pathogens, and the effects of inflammatory response on the developing brain.

Quality of life and illness beliefs in individuals with early psychosis.

PURPOSE: Quality of life (QoL) has become an important outcome measure in early psychosis. This study examined associations between illness beliefs (how individuals perceive their mental health problems), symptom factors and QoL in an early psychosis population. METHODS: Eighty-one individuals with early psychosis completed a battery of questionnaires measuring QoL, illness perceptions, psychotic and affective symptoms. RESULTS: QoL was significantly associated with certain illness beliefs, namely treatment control and consequences of psychosis. Lower levels of QoL were associated with higher depression, anxiety and general psychopathology. QoL was found to be predicted by key illness beliefs. CONCLUSIONS: Causality has not been fully established, but these results suggest that beliefs about mental health problems may have a direct impact on outcome, and point towards possible targets for intervention, such as challenging illness-related appraisals. This is consistent with both general cognitive models of psychosis, and Cognitive Behaviour Therapy for this client group.

Lifetime discrimination associated with greater likelihood of premenstrual dysphoric disorder.

OBJECTIVES: To evaluate whether the stressor of perceived discrimination was associated with premenstrual dysphoric disorder (PMDD) and premenstrual symptoms among minority women. This study builds on previous research that found perceived discrimination was positively associated with other psychiatric illnesses. METHODS: Participants were 2718 Asian, Latina, and black premenopausal women aged 18-40 years who completed the World Mental Health Composite International Diagnostic Interview for the National Latino and Asian American Survey or the National Survey of American Life. Perceived discrimination was assessed with the Everyday Discrimination Scale. DSM-IV-based diagnostic algorithms generated a provisional lifetime diagnosis of PMDD. RESULTS: Eighty-three percent of the participants reported experiencing discrimination (due to race, gender, age, height or weight, or other reasons) in their lifetimes. The frequency of perceived discrimination was positively associated with PMDD (odds ratio [OR] 1.08, 95% confidence interval [CI] 1.05-1.10) and premenstrual symptoms (OR 1.04, 95% CI 1.02-1.05), independent of demographic covariates and social desirability. Women reporting gender discrimination (OR 5.18, 95% CI 1.80-14.90), race discrimination (OR 4.14, 95% CI 1.54-11.11), and other forms of discrimination (OR 6.43, 95% CI 2.11-19.65) were significantly more likely than women without experiences of discrimination to have PMDD. Subtle discrimination was more strongly associated with PMDD (OR 1.12, 95% CI 1.01-1.23) than was blatant discrimination (OR 1.04, 95% CI 0.94-1.15). CONCLUSIONS: This study is the first to demonstrate that perceived discrimination is associated with PMDD and premenstrual symptoms. These findings suggest that the prevalence of these conditions may be lessened by reducing discrimination in women's lives.

Mood and nonmood components of perceived stress and exacerbation of Crohn's disease.

BACKGROUND: Diverse psychological factors are involved in the pathophysiology of stress. In order to devise effective intervention strategies, it is important to elucidate which factors play the most important role in the association between psychological stress and exacerbation of Crohn's disease (CD). We hypothesized that the association between perceived stress and exacerbation of CD would remain after removal of mood and anxiety components, which are largely involved in stress perception. METHODS: In all, 468 adults with CD were recruited and followed in different hospitals and private practices of Switzerland for 18 months. At inclusion, patients completed the Perceived Stress Questionnaire and anxiety and depression were assessed using the Hospital Anxiety and Depression Scale. During the follow-up, gastroenterologists assessed whether patients presented with a CD exacerbation. By means of binary logistic regression analysis, we estimated the factor by which one standard deviation of perceived stress would increase the odds of exacerbation of CD with and without controlling for anxiety and depression. RESULTS: The odds of exacerbation of CD increased by 1.85 times (95% confidence interval 1.43-2.40, P < 0.001) for 1 standard deviation of perceived stress. After removing the anxiety and depression components, the residuals of perceived stress were no longer associated with exacerbation of CD. CONCLUSIONS: The association between perceived stress and exacerbation of CD was fully attributable to the mood components, specifically anxiety and depression. Future interventional studies should evaluate the treatment of anxiety and depression as a strategy for potential prevention of CD exacerbations.

Sex differences in affective response to opioid withdrawal during adolescence.

Drug withdrawal is suggested to play a role in precipitating mood disorders in individuals with familial predisposition. Age-related differences in affective responses to withdrawal might explain the increased risk of mental illnesses when drug use begins during adolescence. Recently we observed that, in contrast to adult male mice, adolescent males exhibited a decrease in immobility in the forced swim test on the third day of withdrawal, as compared with controls. Thus, the present study examined forced swim test behaviors of adolescent female mice during opioid withdrawal. Similar to the male study, adolescent female mice were injected with two morphine regimens which differed in dosage. Three and nine days following discontinuation of morphine administration, forced swim test immobility time and locomotion were evaluated. In contrast to males, which exhibited a decrease in immobility, no significant differences in immobility were observed in female adolescents undergoing withdrawal as compared with saline-injected controls. This sex difference in forced swim test behaviors was not due to changes in overall motor activity, since differences in locomotion were not observed in either male or female adolescent mice. Thus, this study demonstrates sex differences in forced swim test behavior during opioid withdrawal. Forced swim test behaviors are classically used to evaluate mood in rodents, thus this study suggests that opioid withdrawal might affect mood differentially across sexes.
