The increase in cortisol can be exogenous or endogenous. As etiologies of endogenous increase we find: Cushing’s disease, 68% of cases, generally due to an ACTH-producing pituitary tumor; Adrenal Cushing syndrome (17%); Ectopic Cushing syndrome (15%) due to lung tumor most frequently. It is relevant since among its symptoms one of the most notable are the psychiatric alterations it produces, among them mood disorders, depression being the most common, as well as psychotic symptoms, delirium and anxiety disorder.

To carry out a correct differential diagnosis of the pathologies that could present with symptoms of a manic episode.

Clinical case description of a 52-year-old woman, who presented with manic symptoms in 2020, requiring hospitalization. Upon discharge from the acute care unit, she consulted with the endocrinologist due to weight gain, revealing an increase in abdominal diameter, hyperpigmentation, a moon-like face, and a hump. Free cortisol was measured in 24-hour urine, with a high result, followed by brain MRI, and pituitary microadenoma was confirmed.

The patient underwent surgical resection of the microadenoma, which was partially effective, so she maintained high cortisol levels, even despite oral retreatment. In 2023 she had a new manic episode, with a cortisol value of approximately 300 nmol/day.

The importance lies in the correct diagnosis to provide appropriate treatment and avoid the chronicity of the disease and the patient psychiatrization. In this case and as in many other diseases, which present with psychiatric symptoms, it is important to differentiate whether it is a primary psychiatric disorder or are component symptoms of another disease that, upon receiving treatment, would resolve the psychiatric symptoms.

Monthly extended-release injectable risperidone is the new antipsychotic formulation of risperidone available in doses of 75 mg and 100 mg, approved for the treatment of schizophrenia. It contains microcrystals of risperidone that are deposited following intramuscular injection. A fraction of the active ingredient of risperidone is already solubilized and rapidly enters the bloodstream, providing plasma levels similar to oral risperidone on the first day. The microcrystals continue to release risperidone steadily over a period of 4 weeks. No oral supplementation or loading doses are required.

The objective of this study is to demonstrate the effectiveness of treatment with monthly extended-release injectable risperidone in patients with schizophrenia who are followed up as outpatients from the Mental Health Center. The study aims to show that this treatment improves symptoms associated with schizophrenia, leading to an enhancement in the quality of life for these patients.

Analysis and evaluation were conducted on 9 patients diagnosed with Paranoid Schizophrenia and treated with monthly extended-release injectable risperidone from a Mental Health Unit and the Hospital Emergency System during the months of January to April 2023. Among the nine patients, six were previously on oral risperidone treatment exceeding 4 mg, and three were on doses less than 4 mg. The first group received a monthly injectable dose of 100 mg of risperidone, while the second group received 75 mg.

All nine patients showed improvement in positive and anxious symptomatology. Seven of them exhibited improvement in affective and cognitive profiles. None of the patients experienced significant metabolic alterations, and only one of them reported akathisia as a side effect. Furthermore, all patients improved their sleep patterns, and the seven who had behavioral disturbances with a tendency towards aggression no longer exhibited these behaviors.

Monthly extended-release injectable risperidone is beneficial in reducing positive and affective symptoms in patients with schizophrenia. It also improves anxious, cognitive, and behavioral symptomatology. It is considered effective, safe, and well-tolerated for long-term treatment of this disease, regardless of its initial severity. Therefore, it is advisable to consider it as the first therapeutic option in patients with schizophrenia who have responded well to oral risperidone previously.

Tourette syndrome (TS) is a neurodevelopmental disorder characterized by the development of persistent and changing motor and phonic tics over time. The presence of at least two motor tics and one vocal tic that have persisted for at least a period of 1 year is required, and which developed before the age of 18. The most commonly used pharmacological treatment are antipsychotics, with a preference for atypical antipsychotics such as aripiprazole or risperidone. Clonidine and guanfacine have shown effectiveness in suppressing tics, and although generally less effective than antipsychotics, some authors are considering them as first-line treatments. The treatment is also influenced by any comorbidities the patient may present.

To enumerate in a clinical case the pharmacological alternatives for TS, which vary according to the patient’s comorbidities and the intensity of the tic symptoms.

Case study. Anamnesis of the patient and their family.

A 12-year-old boy presenting simple motor and vocal tics for over a year. At the same time that a valuation is requested by child psychiatry, the mother also requests follow-up by neuropediatrics. Other causes are ruled out, an EEG is performed, and a TS diagnosis is made. The initial treatment was low-dose aripiprazole with partial effectiveness. After 3 months, he presents an exacerbation of the tics, interfering with his social and academic life, making it impossible to attend classes. The mother takes him to emergency services, and he is admitted to pediatrics. During the stay in pediatrics, he is diagnosed with Attention Deficit Hyperactivity Disorder, in addition to confirming the TS diagnosis. Extended-release methylphenidate is initiated (neuropediatrics). After starting methylphenidate, the patient’s tics worsen, also presenting insomnia and hyporexia. Due to the diagnosis of ADHD, school failure, and affective symptoms (hypothymia), atomoxetine is initiated. The tics become constant and incapacitating. As the dose of aripiprazole is increased, the child presents extrapyramidal effects. As a therapeutic alternative, guanfacine is initiated, progressively discontinuing aripiprazole. Currently, the child is stable from motor and vocal tics, allowing him to lead a normalized life.

Although guanfacine is not as effective in reducing tics as antipsychotics, since the latter produce more side effects, it is justifiable to use it. This drug is capable of enhancing the therapeutic effect and reducing the adverse effects that antipsychotics could produce. Guanfacine may be a good alternative as a first line in the treatment of Tourette Syndrome with or without attention deficit disorder and hyperactivity .

The coronavirus disease 2019 (COVID-19) has serious physiological and psychological consequences. The long-term (>12 weeks post-infection) impact of COVID-19 on mental health, specifically in older adults, is unclear. We longitudinally assessed the association of COVID-19 with depression symptomatology in community-dwelling older adults with metabolic syndrome within the framework of the PREDIMED-Plus cohort.

Participants (n = 5486) aged 55–75 years were included in this longitudinal cohort. COVID-19 status (positive/negative) determined by tests (e.g. polymerase chain reaction severe acute respiratory syndrome coronavirus 2, IgG) was confirmed via event adjudication (410 cases). Pre- and post-COVID-19 depressive symptomatology was ascertained from annual assessments conducted using a validated 21-item Spanish Beck Depression Inventory-II (BDI-II). Multivariable linear and logistic regression models assessed the association between COVID-19 and depression symptomatology.

COVID-19 in older adults was associated with higher post-COVID-19 BDI-II scores measured at a median (interquartile range) of 29 (15–40) weeks post-infection [fully adjusted β = 0.65 points, 95% confidence interval (CI) 0.15–1.15; p = 0.011]. This association was particularly prominent in women (β = 1.38 points, 95% CI 0.44–2.33, p = 0.004). COVID-19 was associated with 62% increased odds of elevated depression risk (BDI-II ≥ 14) post-COVID-19 when adjusted for confounders (odds ratio; 95% CI 1.13–2.30, p = 0.008).

COVID-19 was associated with long-term depression risk in older adults with overweight/obesity and metabolic syndrome, particularly in women. Thus, long-term evaluations of the impact of COVID-19 on mental health and preventive public health initiatives are warranted in older adults.

The consequences for the COVID-19 pandemic in the newborns of affected mothers remains unknown. Previous clinical experiences with other infections during pregnancy lead to considered pregnant women and their offspring especially vulnerable for SARS-COV-2. That is, the underlying physiopathological changes caused by the infection (e.g. storm of cytokines, micro-coagulation in placenta or vertical transmission) could clearly compromise fetal neurodevelopment.

To analyze the impact of maternal SARS-COV-2 infection during pregnancy in early neurodevelopment of infants gestated during the COVID-19 pandemic period compared to those gestated immediately prior (2017-2021).

212 pregnant women (14% infected) were followed throughout their pregnancy and postpartum, including newborn development. SARS-COV-2 infection was serologically confirmed during pregnancy. The Brazelton Neonatal Assessment Scale (NBAS) was administered at 6 weeks old by a trained neonatologist to evaluate neurological, social and behavioral aspects of newborn’s functioning. Differences in NBAS scores between cases and controls were tested by ANOVAs. All the analysis were adjusted for maternal age, sociodemographic status, anxious-depressive symptomatology, infant’s sex and gestational age at birth and NBAS, and for the period of gestation (previous or during COVID-19 pandemic).

NBAS social interactive dimension was significantly decreased in those infants exposed to prenatal SARS-COV-2 (F=4.248, p=.043), particularly when the infection occurred before the week 20 of gestation. Gestation during COVID-19 pandemic did not alter NBAS subscales.

SARS-COV-2 infection during pregnancy seems to be associated with lower NBAS scores on social dimension in 6 weeks old exposed newborns.

Bipolar disorder is related with functional impairment in euthymia. The contribution of biological functions such as sleep, sexual functioning; or the presence of obesity on this loss remain understudied.

The aim of this work was to study the influence of biological determinants in context with clinical and demographical determinants of functioning in a 3-year cohort of euthymic BD patients.

In this multicentric study 67 euthymic adult bipolar outpatients were followed during three years. Functioning was assessed with FAST, insomnia severity with Oviedo Sleep Questionnaire (OSQ) and, sexual functioning with Changes on Sexual Functioning Questionnaire (CSFQ-14) and obesity was expressed as body mass index (BMI). The basal effect of sleep, sexual functioning and obesity (Time 0) on FAST (Time 3) was analyzed with a mixed ordinal regression model including time effect, age, sex, number of manic and depressive episodes, euthymia length, and comorbidity with personality disorder. Change in functioning (Time 3 to 0) was analyzed in another mixed model also considering the difference in biological determinants (Time 3 to 0) and the presence of mood episodes during the period.

A basal worse sexual functioning, a higher severity of insomnia and a higher BMI predicted a worse functioning at three years (p=0.005, p=0.043, p=0.05 respectively). Regarding FAST difference from Time0 to 3, only having a manic episode related to an impairment on functioning (p=0.027).

Sexual functioning, quality of sleep and BMI are predictors of functioning in euthymia in BD. Manic episodes in the following contribute to impairments on functioning more than depressive episodes.

Maternal stress during pregnancy influences fetal neurodevelopment, especially by the dysregulation of the HPA axis. However, less is known about whether maltreatment or stressful life experiences previous to pregnancy influence on developmental outcomes in the offspring.

To analyze newborns’ neurobehavioral profiles in a cohort of healthy pregnant women, according to 1) childhood and recent maternal adverse experiences and 2) mother-infant attachment.

150 women were followed during the three trimesters of pregnancy. CTQ and AAT tests were employed to evaluate childhood and recent experiences of maltreatment, while infant and recent adverse experiences were evaluated using ETI-SR and SRSS, respectively. Newborns neurobehavioral profiles were defined at 8 weeks using the Neonatal Behavioral Assessment Scale (NBAS) and their temperament was assessed with IBQ. PBQ and PAI scales were employed to assess mother-infant attachment. A linear regression model was performed, adjusting for possible confounders.

Maternal childhood sexual abuse seems to be associated with greater difficulties in the newborns control of reactivity to external stimuli (β=0,517; p-value=0.001), while recent maternal stressful experiences are related to difficulties for states regulation (β=0,29; p-value=0,038). Regarding attachment, maltreated mothers tend to show ambivalent and avoidant styles. Interestingly, postnatal mother-infant attachment seems to modulate autonomous, motor and social-interactive abilities in the offspring (β=-0,227; p-value=0,033 // β=-0,329; p-value=0,006).

Newborns from mothers exposed to maltreatment and negative life events previous to pregnancy show difficulties to organize and regulate the reactions to psychosocial stimuli. Future studies must disentangle whether maternal attachment style is a modulator of this association.

Cortisol, the hormonal endpoint of Hypothalamic Pituitary Adrenal (HPA) axis, coordinates the body response in front of daily stressful situations. Disturbances in cortisol circadian rhythm have been implicated in the pathophysiology of depression and neurodevelopment lasting consequences. Although pregnancy entails a progressively increase in cortisol levels, the consequences of subclinical depression traits during pregnancy in cortisol circadian rhythm remains unclear.

To analyze the impact of prenatal subclinical depressive symptomatology in cortisol circadian rhythm through pregnancy and its relevance for postpartum depression risk.

A cohort of 112 healthy pregnant women (Mean age±SD=32.32±4.37) of the general population was followed throughout their first pregnancy and first two months of postpartum period. Diurnal salivary cortisol curve (four measures) was obtained for every trimester; the Area Under the Curve with respect to the ground (AUCg) and with respect to the increase (AUCi) were used as measures of basal HPA axis functioning. Depressive symptomatology was assessed every pregnancy trimester and postpartum period following EPDS criteria. All the analyses were adjusted for maternal age, weight, ethnicity and socioeconomic status and sample collection’s time.

Prenatal subclinical depressive symptomatology (EPDS>10) was associated with a blunted cortisol rhythm during first trimester (F= 3.913,p=.011) but not during second (F=2.629, p=056) or third trimesters (F=.411,p=.724). Furthermore, a logistic regression model showed a positive association between Prenatal subclinical depressive symptomatology and the risk of postpartum depression (χ2=13.8, p<.001,OR=9.6; 95%CI 2.5–35.5).

Women with subclinical depressive symptomatology in early pregnancy had alterations in cortisol circadian rhythmicity and a higher risk of postpartum depression.

Cognition heavily relies on social determinants and genetic background. Latin America comprises approximately 8% of the global population and faces unique challenges, many derived from specific demographic and socioeconomic variables, such as violence and inequality. While such factors have been described to influence mental health outcomes, no large-scale studies with Latin American population have been carried out. Therefore, we aim to describe the cognitive performance of a representative sample of Latin American individuals with schizophrenia and its relationship to clinical factors. Additionally, we aim to investigate how socioeconomic status (SES) relates to cognitive performance in patients and controls.

We included 1175 participants from five Latin American countries (Argentina, Brazil, Chile, Colombia, and Mexico): 864 individuals with schizophrenia and 311 unaffected subjects. All participants were part of projects that included cognitive evaluation with MATRICS Consensus Cognitive Battery and clinical assessments.

Patients showed worse cognitive performance than controls across all domains. Age and diagnosis were independent predictors, indicating similar trajectories of cognitive aging for both patients and controls. The SES factors of education, parental education, and income were more related to cognition in patients than in controls. Cognition was also influenced by symptomatology.

Patients did not show evidence of accelerated cognitive aging; however, they were most impacted by a lower SES suggestive of deprived environment than controls. These findings highlight the vulnerability of cognitive capacity in individuals with psychosis in face of demographic and socioeconomic factors in low- and middle-income countries.

Social and environmental factors such as poverty or violence modulate the risk and course of schizophrenia. However, how they affect the brain in patients with psychosis remains unclear.

We studied how environmental factors are related to brain structure in patients with schizophrenia and controls in Latin America, where these factors are large and unequally distributed.

This is a multicentre study of magnetic resonance imaging in patients with schizophrenia and controls from six Latin American cities. Total and voxel-level grey matter volumes, and their relationship with neighbourhood characteristics such as average income and homicide rates, were analysed with a general linear model.

A total of 334 patients with schizophrenia and 262 controls were included. Income was differentially related to total grey matter volume in both groups (P = 0.006). Controls showed a positive correlation between total grey matter volume and income (R = 0.14, P = 0.02). Surprisingly, this relationship was not present in patients with schizophrenia (R = −0.076, P = 0.17). Voxel-level analysis confirmed that this interaction was widespread across the cortex. After adjusting for global brain changes, income was positively related to prefrontal cortex volumes only in controls. Conversely, the hippocampus in patients with schizophrenia, but not in controls, was relatively larger in affluent environments. There was no significant correlation between environmental violence and brain structure.

Our results highlight the interplay between environment, particularly poverty, and individual characteristics in psychosis. This is particularly important for harsh environments such as low- and middle-income countries, where potentially less brain vulnerability (less grey matter loss) is sufficient to become unwell in adverse (poor) environments.

To analyze the different combination of personality pathology associated to variables of psychiatric hospital admissions (number of admissions, total of days spent as psychiatric inpatient, average of days for admission, and number of admissions in a day care hospital).

The ICD-10 and DSM-IV modules of the semi-structured interview IPDE (International Personality Disorders Examination) were administered, in a sample of 107 adolescent psychiatric patients (M=15.8, SD=0.8 years old; age rank 15-17; 79% female).

Personality pathology group identified by the IPDE showed significantly higher number (p< .001) of psychiatric admissions (M=1.48) than no personality pathology group (M=0.57), but not significant higher number of admissions in a day care hospital. Psychotic patients showed the highest rate of admissions (M=2.88). In present sample, between 30% and 38% of all hospital admitted patients showed a Cluster B personality disorder (PD).The users of psychiatric inpatient services with a complex PD (two o more PD from different clusters) presents in average: 2-2.5 admissions, 34-53 total days spent as psychiatric inpatient, and 11-16 days on each admission.

Patients with psychotic disorders or complex PD were the highest users of inpatients services, but not of day care hospital admissions.

Immigration in Spain is from the early ‘90s phenomenon of demographic and economic importance, according to INE, in January 2011 first residing in the country nearly 6.7 million people born outside our borders. In recent years, many immigrants are living in especially difficult circumstances.

Show that these people undergo a series of very specific stressors and duels: precarious and harsh working conditions, poor diet, loneliness and lack of social support… This would enhance the appearance of psychiatric symptoms in various areas, closely related to lifestyles that maintain and in some cases precipitate substance use in this group, primarily those that have a sedative profile.

We will present the clinical case of a 34 year old Nigerian male. No somatic or psychiatric history of interest. Cannabis smoker since adolescence. A year after his arrival in Spain admitted to our inpatient unit due to clinical psychotic. Was a challenge from the point of view of psychopharmacological have many side effects with low doses of typical antipsychotics

Disappearance of psychotic and affective symptoms to approach the case from a pharmacological perspective, social and cultural.

Addressing the relationship between life stressors and cannabis as a trigger or catalyst for psychotic episodes in individuals predisposed. Pathological elaborations of cultural integration of an immigrant (whether by denial of the original culture or over-identification with the host culture) facilitates the use of toxic either for blending with Western consumer culture or cultural consumption radicalization toxic in some East African countries.

Given the high prevalence, severity and difficulty recognizing psychiatric disorders in patients with TBI, it is necessary to conduct a detailed history, gathering information on the location of the lesion and its relationship with the table in the psychopathological examination.

Illustrated by a clinical case, the close relationship between the injury of specific brain areas and the emergence of psychopathology that allows us to deepen the understanding of the biological substrate of mental disorders.

Exposure of a clinical picture and brief literature review of the existing literature.

We report the case of a man of 49 years old, no personal or family history was admitted to the hospital after a traffic accident with severe TBI. Computed tomography (CT) scan shows intraparenquematoso right temporal hematoma, subarachnoid hemorrhage, subdural hematoma right, pneumocephalus front right, front left fracture of both orbits and right maxillary sinus.

The interest in the study and the relationship of psychiatric symptoms with the location of the lesions, we can provide improved understanding of the biological basis of mental disorders.
