Background
A significant proportion of people with clozapine-treated schizophrenia develop ‘checking’ compulsions, a phenomenon yet to be understood.
AimsTo use habit formation models developed in cognitive neuroscience to investigate the dynamic interplay between psychosis, clozapine dose and obsessive–compulsive symptoms (OCS).
MethodUsing the anonymised electronic records of a cohort of clozapine-treated patients, including longitudinal assessments of OCS and psychosis, we performed longitudinal multi-level mediation and multi-level moderation analyses to explore associations of psychosis with obsessiveness and excessive checking. Classic bivariate correlation tests were used to assess clozapine load and checking compulsions. The influence of specific genetic variants was tested in a subsample.
ResultsA total of 196 clozapine-treated individuals and 459 face-to-face assessments were included. We found significant OCS to be common (37.9%), with checking being the most prevalent symptom. In mediation models, psychosis severity mediated checking behaviour indirectly by inducing obsessions (r = 0.07, 95% CI 0.04–0.09; P < 0.001). No direct effect of psychosis on checking was identified (r = −0.28, 95% CI −0.09 to 0.03; P = 0.340). After psychosis remission (n = 65), checking compulsions correlated with both clozapine plasma levels (r = 0.35; P = 0.004) and dose (r = 0.38; P = 0.002). None of the glutamatergic and serotonergic genetic variants were found to moderate the effect of psychosis on obsession and compulsion (SLC6A4, SLC1A1 and HTR2C) survived the multiple comparisons correction.
ConclusionsWe elucidated different phases of the complex interplay of psychosis and compulsions, which may inform clinicians’ therapeutic decisions.

The Uniform Information Density (UID) hypothesis proposes that speakers communicate by transmitting information close to a constant rate. When choosing between two syntactic variants, it claims that speakers prefer the variant distributing information most evenly, avoiding signal peaks and troughs. If speakers prefer transmitting information uniformly, then comprehenders should also prefer a uniform signal, experiencing difficulty whenever confronted with informational peaks. However, the literature investigating this hypothesis has focused mostly on production, with only a few studies considering comprehension. In this study, we investigate comprehension in two eye-tracking experiments. Participants read sentences of two different lengths, reflecting different degrees of density, containing either a dense structure (a nominal compound, NC) or a structure that spreads the information through more words (a noun followed by a prepositional phrase, PP). Favoring the UID hypothesis, participants gazed longer at text segments following the critical structure when it was an NC than when it was a PP. They also regressed more in sentences containing longer structures. However, the pattern of results was not as clear as expected, potentially reflecting participants’ experience with the denser structure or task differences between production and comprehension. These aspects should be taken into account in future research investigating the UID hypothesis for comprehension.

Objective:
The COVID-19 pandemic has affected the continuity of cognitive rehabilitation (CR) worldwide. However, the use of teleneuropsychology (TNP) to provide CR has contributed significantly to the continuity of treatment. The objective of this study was to measure the effects of CR via the TNP on cognition, neuropsychiatric symptoms, and memory strategies in a cohort of patients with Mild Cognitive Impairment (MCI).
Participants and Methods:A sample of 60 patients (60% female; age: 72.4±6.96) with MCI according to Petersen criteria was randomly divided into two groups: 30 cases (treatment group) and 30 controls (waiting list group). Subjects were matched for age, sex, and MMSE or MoCA.
The treatment group received ten weekly CR sessions of 45 minutes weekly. Pre-treatment (week 0) and post-treatment (week 10) measures were assessed for both groups. Different Linear Mixed Models were estimated to test treatment effect (CR vs. Controls) on each outcome of interest over Time (Pre/Post), controlling for Diagnosis, Age, Sex, and MMSE/MoCA performance.
Results:A significant Group (Control/Treatment) x Time (pre/post) interaction revealed that the treatment group at 10 weeks had better scores in cognitive variables: memory (RAVLT learning trials p=0.030; RAVLT delayed recall p=0.029), phonological fluency(p=0.001), activities of daily living (FAQ p=0.001), satisfaction with memory performance (MMQ Satisfaction p=0.004) and use of memory strategies (MMQ Strategy p=0.00), and a significant reduction of affective symptomatology: depression (GDS p=0.00), neuropsychiatric symptoms (NPIQ p=0.045), Forgetfulness (EDO-10 p=0.00), Stress (DAS Stress p=0.00).
Conclusions:This is the first study to test CR using teleNP in South America. Our results suggest that CR through teleNP is an effective intervention to improve performance on cognitive variables and reduce neuropsychiatric symptomatology compared to patients with MCI. These results have great significance in the context of the COVID-19 pandemic in South America, where teleNP is proving to be a valuable tool.

Summary
Described over a century ago, schizophrenia still presents personal, clinical and scientific challenges, and is increasingly considered a concept rather than a single disorder. It has become a paradigmatic psychiatric disorder while remaining something of an enigma. Defined by a syndrome of psychotic phenomena (positive phenomena such as delusions, hallucinations or disordered thought structure) and negative features resulting from motivation and emotional dysfunction, schizophrenia is defined by symptoms lasting at least 4 weeks and impairment for 6 months or more [1, 2]. Where the illness is short-lived, the clinical syndrome is defined as a schizophrenia-related diagnosis [1]. The clinical presentation usually encompasses features prominent in other psychiatric conditions such as cognitive dysfunction, motor abnormalities, obsessional phenomena or depression. These additional features not included in the definition of schizophrenia underscore its pervasive neural dysfunction; they influence management and often shape the clinical outcome. The seeds of schizophrenia may be sown in early life with aberrant childhood development in multiple domains [2], but the clinical syndrome typically presents in early adulthood (Figure 9.10.1); abnormal neural connectivity may underly these seemingly remote phenomena.

Pellet injection is currently the primary candidate for achieving efficient plasma fuelling, one of the key issues for steady-state operation in large fusion devices. In this paper, pellet injection experiments are performed for several magnetic configurations of the TJ-II stellarator. The aim of this study is to increase the understanding of the role played by rational surfaces in plasmoid drift and deposition profiles in stellarators. The analysis of experimentally observed plasmoid drifts is supported by simulations of such cases made with the HPI2 code. Plasmoid drift is found to be significantly reduced, as in tokamaks, in the vicinity of rational surfaces. This is attributed to the fact that plasmoid external charge reconnection lengths are shorter near rational surfaces, resulting in a more effective damping of the plasmoid drift. Although the effect of plasmoid external currents on the drift is expected to be negligible in stellarators, compared with those caused by plasmoid internal currents, the effect observed in TJ-II is clearly measurable. In addition, simulations show that enhanced drift reductions near rational surfaces lead to significantly different deposition profiles for the magnetic configurations included in this study. This implies that it should be possible to select the magnetic configurations to obtain more efficient pellet fuelling.

This article examines the effects of implementing the proposals of the European Commission to institute a Capital Market Union (CMU) on the diverse landscape of residential capitalism in Europe. The CMU will bypass existing national institutional blockades that left core countries of the Eurozone, namely Germany, France and Italy, largely untouched by the housing-centred financialization that developed in countries like Spain, Ireland, the UK and the Netherlands. It is widely acknowledged that the rise in securitized mortgage debt contributed to the global financial crisis. As part of the CMU, the new European Commission is promoting mortgage securitization throughout the EU and thereby rescaling the political economy of housing finance that was hitherto rooted in national, institutional models. We argue that countries which ‘missed’ the previous housing boom will not be able to prevent future housing-centred financialization. CMU thus signifies a spatial expansion of the debt-led accumulation model.

In a recent study, Fernandez et al. (2021) investigated parafoveal processing in L1 English and L1 German–L2 English readers using the gaze contingent boundary paradigm (Rayner, 1975). Unexpectedly, L2 readers derived an interference from a non-cognate translation parafoveal mask (arrow vs. pfeil), but derived a benefit from a German orthographic parafoveal mask (arrow vs. pfexk) when reading in English. The authors argued that bilingual readers incurred a switching cost from the complete German word, and derived a benefit by keeping both lexicons active from the partial German word. In this registered report, we further test this finding with L1 German–L2 English participants using improved items, but with the sentences presented in German. We were able to replicate the non-cognate translation interference but not the orthographic facilitation. Follow up comparisons showed that all parafoveal masks evoked similar inhibition, suggesting that bilingual readers do not process non-cognate semantic or orthographic information parafoveally.

Introduction
Adverse childhood experiences (ACEs), defined as abuse, neglect, or a dysfunctional household in childhood, have been associated with suicidality (Fjeldsted et al., 2020). Every type of ACE has a direct impact on suicide ideation, self-harm and/or suicide attempt (Angelakis et al., 2019).
ObjectivesWe aim to quantify the association between types of ACEs (including emotional, physical, sexual abuse, and emotional and physical neglect) and the number of suicide attempts in lifetime.
MethodsWe included 748 patients who attempted suicide at least once. They were asked to complete the Columbia-Suicide Severity Rating Scale (CSSRS), and the Childhood Trauma Questionnaire-Short Form (CTQ-SF). Logistic regression models were run to assess the association between each ACE type and the number of suicide attempts.
ResultsPoisson univariate regression analyses show a linear trend in the relationship between having a higher number of suicide attempts and having suffered every ACE type in childhood (p<0.05). Our results show a lower percentage of previous suicide attempts among participants without ACEs, and an increasing tendency among patients with various types of ACEs. The rate of ACEs types is significantly higher in the group with previous suicide attempts than in the first-attempt group (p=0.000).

ConclusionsThis study contributes to clarify the role of childhood trauma in the number of suicide attempts in lifetime. This has important implications for reducing suicide rates, and preventing future re-attempts. Further studies analysing every construct of childhood trauma may contribute to the detection of suicidal behaviour.

Introduction
Disorganized attachment has been described as an important risk factor for developing serious mental disorders in childhood, adolescence and adulthood, such as borderline personality disorder, psychoses, afective disorders, and a higher suicide risk, for instance. Bonding disorders (BD) in parents are related to insecure and disorganized attachment in children. BD can be early diagnosed at 4 to 6 weeks after birth.
ObjectivesDetermine if there is a significant difference between the results of the prevalence of affective disorders, disorganized attachment, and suicidal risk five years after the birth of the offspring of parents with and without attachment disorders detected in the first year postpartum during the covid-19 pandemic.
MethodsDescribe a pilot project of an analytical prospective study following a cohort of parents from the cohort SAMPECO/PEMHSCO (Perinatal Mental Health in Spain during the Covid-19 pandemic). The cohort is planned to be divided into two groups: with bonding disorders an without bonding disorders, which was established using the Postpartum Bonding Questionnaire (Brockington, 2006). Follow the offspring of both groups for 5 years and compare the results of disorganized attachment, affective disorders and suicide risk.
ResultsThe cohort SAMPECO/PEMHSCO was recruited between March 2021 and June 2022. There was measured postpartum depression in mothers and fathers using the EPDS and bonding disorders in parents using the PBQ validated to the Spaniard population. More than 1500 families were involved at the beginning and around 450 families finished the follow-up six months after birth. Around 500 families were lost because of non-right contact information.
ConclusionsThe covid-19 pandemic has seriously affected the mental health of the general population. Consequently, there is a higher demand for mental health assistance by public and private sanity sectors. Currently, the youth population is suffering very much from the consequences of isolation and other social factors, and many families who had babies in this period haven’t had enough support to breed and look after both their babies and themselves. Some papers suggest that the prevalence of perinatal mental disorders in parents has increased since the covid-19 pandemic because of several factors. Paradoxically, despite the high preventive potential of early intervention in the perinatal period, there are not yet exist well-equipped perinatal mental health units to solve this problem. It is urgent to boost the development of Perinatal Mental Health Services to prevent a major worsening of the situation and to prevent the increasing rate of severe mental disorders in children, adolescents and adults.

Introduction
Up to 50% of patients with brain tumors experience psychiatric symptoms, and rates up to 80% have been reported in malignant neoplasms such as glioblastoma multiforme (GBM). Still, clinical presentation as mania-like syndromes is a rare phenomenon, mainly occurring when frontal structures are compromised.
We present the case of a 42-year-old woman who was admitted to our hospital due to manic symptoms coinciding with a recurrence of a bifrontal GBM, for which she underwent surgery 5 months prior.
Objectives1) To describe the clinical particularities of this case, focusing on the differential diagnosis.
2) To review the association between manic symptoms and frontal dysfunction caused by brain tumors, with special interest on GBM.
MethodsA review of the patient’s clinical history and complementary tests performed was carried out. Likewise, we reviewed the available literature in relation to manic symptoms related to brain tumors.
ResultsThe patient’s GBM recurrence presented with late onset symptoms of mania, including euphoric mood, increased spending, ideas of grandiosity and hyper-religiosity. She had no previous psychiatric history but, interestingly, she had an extensive affective burden in her family, with 4 consummated suicides. However, she also presented other clinical signs, such as disorientation, perseveration, mild memory impairment and stereotyped motor behaviors, that pointed to relevant frontal lobe dysfunction, suggesting Moria as a possible contribution for the symptoms described.
Manic symptoms in the context of brain tumors appear in 7-15% of patients with psychiatric symptoms, usually associated with right frontal dysfunction (75% of cases). Bifrontal affectation, such as this patient, is only described in 6% of cases. Although fast growing, malignant tumors have been associated with higher rates of psychiatric symptoms, no correlation has been described between these and brain tumor histology.
Conclusions- The presence of atypical manic symptoms, such as those presented in this case, should raise clinical concern for secondary mania.
- Moria shares similarities with mania, including mood elevation, tendency to hilarity or hyper-sexuality, that may hinder diagnosis of patients with frontal dysfunction.
- This case outlines the difficulties in making a differential diagnosis in patient with both manic and neurological signs, and highlights the implication of frontal structures in the development of manic symptoms.

Introduction
Maintenance electroconvulsive therapy (mECT) is an option in the treatment of affective disorders which progress is not satisfactory. It is certainly neglected and underused during the clinical practice.
ObjectivesTo evaluate the efficacy of mECT in reducing recurrence and relapse in recurrent depression within a sample of three patients.
MethodsWe followed up these patients among two years since they received the first set of electroconvulsive sessions. We applied the Beck Depression Inventory (BDI) in the succesives consultations for evaluating the progress.
ResultsThe three patients were diagnosed with Recurrent Depressive Disorder (RDD). One of them is a 60 year old man that received initially a cycle of 12 sessions; since then he received 10 maintenance sessions. Other one is a 70 year old woman that received initially a cycle of 10 sessions; since then she received 6 maintenance sessions. The last one is a 55 year old woman that received initially a cycle of 14 sessions; since then she received 20 maintenance sessions.
All of them showed a significant reduction in depressive symptoms evaluated through BDI and clinical examination. In the first case, we found a reduction in the BDI from the first consultation to the last that goes from 60 to 12 points; in the second case, from 58 to 8 points; and in the last case, from 55 to 10 points. The main sections that improved were emotional, physical and delusional.
As side-effects of the treatment, we found anterograde amnesia, lack of concentration and loss of focus at all of them.
ConclusionsWe find mECT as a very useful treatment for resistant cases of affective disorders like RDD.
It should be considered as a real therapeutic option when the first option drugs have been proved without success.

Introduction
Schizotypal disorder is conceptualized as a stable personality pathology (Cluster A) and as a latent manifestation of schizophrenia. It can be understood as an attenuated form of psychosis or high-risk mental state, which may precede the onset of schizophrenia or represent a more stable form of psychopathology that doesn’t necessarily progress to psychosis.
ObjectivesTo exemplify the continuum of psychosis
MethodsReview of scientific literature based on a relevant clinical case.
Results39-year-old male living with his parents. He started studying philosophy. He is a regular cannabis user and has an aunt with schizophrenia. He’s admitted to psychiatry for behavioral disturbance in public. He refers to having been hearing a beeping noise in his street for months, what he interprets as a possible way of being watched due to his past ideology. Without specifying who and why, he sometimes shouts “until it bursts” to stop the noise and he thinks that his neighbours alerted the police about his behavior. During the interview he alludes to Milgram’s experiment, saying that throughout history there have been crimes against humanity and those who pointed them out were labeled “crazy”. His father refers that he has always been “strange” and with certain extravagant revolutionary ideas and thoughts. He doesn’t maintain social relationships and dedicates himself to reading and writing.
ConclusionsIt’s important to understand psychosis as a continuum to advance the understanding of etiology, pathophysiology and resilience of psychotic disorders and to develop strategies for prevention and early intervention

Introduction
There is a fine line separating psychiatry and neurology. Most movement disorders can have psychiatric symptoms, not only those caused by the disease itself, but also those induced by the drugs used to treat them.
ObjectivesPresentation of a clinical case about a patient diagnosed with Parkinson’s disease presenting a several-month-long delirious episode due to dopaminergic drugs.
MethodsLiterature review on drug-induced psychosis episodes in Parkinson’s disease.
ResultsA 57-year-old patient with diagnosis of Parkinson’s disease for six years, who went to the emergency room accompanied by his wife due to delirious ideation. He was being treated with levodopa, carbidopa and rasagiline for years, and rotigotine patches whose dosage was being increased over the last few months.
His wife reported celotypical clinical manifestations and multiple interpretations of different circumstances occurring around her. He chased her on the street, had downloaded an app to look for a second cell phone because he believed she was cheating on him, and was obsessed with sex. He had no psychiatric background. It was decided to prescribe quetiapine.
The following day, he returned because he refused to take the medication since he thought he was going to be put to sleep or poisoned. It was decided to admit him to Psychiatry.
During the stay, rasagiline and rotigotine were suspended. Olanzapine and clozapine were introduced, with behavioral improvement and distancing from the psychotic symptoms which motivated the admission. The patient was also motorically stable. Although levodopa is best known for causing psychotic episodes, the symptons were attributed to rotigotine patches for temporally overlapping the dose increase.
ConclusionsPsychiatric symptoms are the third most frequent group of complications in Parkinson’s disease after gastrointestinal complications and abnormal movements. All medication used to control motor disorders can lead to psychosis, not only dopaminergics, but also selegiline, amantadine and anticholinergics.
Excessive stimulation of mesocortical and mesolimbic dopaminergic pathways can lead to psychosis, which is the most common psychiatric problem related to dopaminergic treatment.
In the face of a psychotic episode, antiparkinsonian drugs which are not strictly necessary for motor control should be withdrawn. If this is not sufficient, levodopa dose should be reduced, considering the side effects that may occur. When the adjustment of antiparkinsonian treatment is not effective, neuroleptics, especially quetiapine or clozapine, should be administered. In a recent study, pimavanserin, a serotonin 5-HT2 antagonist, was associated with approximately 35% lower mortality than atypical antipsychotic use during the first 180 days of treatment in community-dwelling patients.
Medication should always be tailor-made to suit each patient and we usually have to resort to lowering or withdrawing the dopaminergic medication.

Introduction
Bipolar disorder comorbidity rates are the highest among the major mental disorders. In addition to other intoxicants, alcohol is the most abused substance because it is socially accepted and can be legally bought and consumed. Estimates are between 40-70% with male predominance, which further influences the severity with a more complicated course of both disorders.
ObjectivesThe objective of this article is to highlight the impact of substance use on the course and prognosis of bipolar disorder, as well as to make a differential diagnosis of a manic episode in this context.
MethodsBibliographic review of scientific literature based on a relevant clinical case.
ResultsWe present the case of a 45-year-old male patient. Single with no children. Unemployed. History of drug use since he was young: alcohol, cannabis and amphetamines. Diagnosed with bipolar disorder in 2012 after a manic episode that required hospital admission. During his evolution he presented two depressive episodes that required psychopharmacological treatment and follow-up by his psychiatrist of reference. Since then, he has been consuming alcohol and amphetamines occasionally, with a gradual increase until it became daily in the last month. He went to the emergency department for psychomotor agitation after being found in the street. He reported feeling threatened by a racial group presenting accelerated speech, insomnia and increased activity.
ConclusionsThe presence of substance abuse complicates the clinical presentation, treatment and development of bipolar disorder. It is associated with a worse prognosis with multiple negative consequences including worsening symptom severity, increased risk of suicide and hospitalization, increased medical morbidity and complication of social problems. In addition, this comorbidity delays both the diagnosis and treatment, by masking the symptoms, and making more difficult an adequate differential diagnosis.

Introduction
In the early stages of schizophrenia the person experiences feelings of strangeness about themselves, difficulty in making sense of things and difficulty in interacting with their environment. Based on this, self-disorder assessment instruments have been developed and empirical studies have been conducted to assess people at risk of developing a schizophrenia spectrum disorder. These studies show that self-disorders are found in pre-psychotic stages and that their manifestation can predict the transition to schizophrenia spectrum disorders.
ObjectivesWe present the case of a patient with multiple diagnoses and mainly dissociative symptoms who, after years of evolution, was diagnosed with schizophrenia.
MethodsBibliographic review including the latest articles in Pubmed about self-disorders and schizophrenia.
ResultsWe present the clinical case of a 51-year-old woman with a long history of follow-up in mental health consultations and with multiple hospital admissions to the psychiatric unit, with several diagnoses including: dissociative disorder, histrionic personality disorder, adaptive disorder unspecified psychotic disorder and, finally, schizophrenia. The patient during the first hospital admissions showed a clinical picture of intense anxiety, disorientation and claiming to be a different person. The patient related these episodes to stressors she had experienced, and they improved markedly after a short period of hospital admission. Later, psychotic symptoms appeared in the form of auditory and visual hallucinations and delusional ideation, mainly of harm, so that after several years of follow-up and study in mental health consultations and in the psychiatric day hospital, she was diagnosed with schizophrenia and treatment with antipsychotics was introduced, with a marked clinical improvement being observed.
ConclusionsIt is important to take into account this type of symptoms (self-disorders), as they allow the identification of individuals in the early stages of the disorder and create the opportunity for early therapeutic interventions.

Introduction
Bipolar Disorder (BD) is considered a serious mental disorder characterized by a changing mood that fluctuates between two completely opposite poles. It causes pathological and recurrent mood swings, alternating periods of exaltation and grandiosity with periods of depression. We talk about rapid cyclers when four or more manic, hypomanic or depressive episodes have occurred within a twelve-month period. Mood swings can appear rapidly. Approximately half of the people with bipolar disorder may develop rapid cycling at some point.
ObjectivesPresentation of a clinical case about a patient with Bipolar Disorder with rapid cycling and poor response to treatment.
MethodsReview of the scientific literature based on a clinical case.
Results33-year-old male, single, living with his mother, under follow-up by mental health team since 2012. First debut of manic episode in 2010. The patient has filed multiple decompensations related to consumption of toxics (alcohol and cannabis). Currently unemployed. He attended to the emergency service in June 2022 accompanied by his mother, who reported that he was restless. The patient refers that he has interrupted the treatment during the vacations, having sleep rhythm disorder with abuse of caffeine drinks. Currently the patient does not recognize any consumption.The patient reports that during the village festivals he felt very energetic, occasionally consuming drinks rich in taurine and sugars, even having conflicts with people of the village. Finally, the patient was stabilized with Lithium 400 mg and Olanzapine. In September, the patient returned to the emergency service on the recommendation of his referral psychiatrist due to therapeutic failure. The only relevant finding we observed in the analytical determinations were low lithium levels (0.4 mEq/L). The transgression of sleep rhythms and the abuse of psychoactive substances required the admission of the patient to optimize the treatment (Clozapine, Lithium, Valproic Acid). At discharge, he is euthymic, has not presented behavioral alterations and is resting well. Finally, it was decided that the patient should go to the Convalescent Center to continue treatment and achieve psychopathological stability.
ConclusionsBipolar disorder is an important mental illness, having an incidence of 1.2%, being responsible for 20% of all mood disorders. Therefore, it is important to perform an adequate and individualized follow-up of each patient. Treatment with mood stabilizers tries to improve and prevent manic and depressive episodes, improving chronicity and trying to make the long-term evolution as good as possible, being important psychoeducation and psychotherapy.

Introduction
The neurobiology of gambling disorder (GD) is not yet fully understood. Although dysfunctional signalling involved in energy homeostasis has been studied in substance use disorders, it should be examined in detail in GD.
ObjectivesTo compare different endocrine and neuropsychological factors between individuals with GD and healthy controls (HC), and to explore endocrine interactions with neuropsychological and clinical variables.
MethodsA case-control design was performed in 297 individuals with GD and 41 HC, assessed through a semi-structured clinical interview and a psychometric battery, adding 38 HC in the evaluation of endocrine and anthropometric variables.
ResultsIndividuals with GD presented higher fasting plasma ghrelin (p<.001) and lower LEAP2 and adiponectin concentrations (p<.001) than HC adjusting for body mass index (BMI). The GD group reported higher cognitive impairment regarding cognitive flexibility and decision-making strategies, a worse psychological state, higher impulsivity levels, and a more dysfunctional personality profile. Despite failing to find significant associations between endocrine factors and either neuropsychological or clinical aspects in GD, some impaired cognitive dimensions and lower LEAP2 concentrations significantly predicted GD presence.
ConclusionsThis study suggests distinctive neuropsychological and endocrine dysfunctions may operate in individuals with GD, predicting GD presence. Further exploration of endophenotypic vulnerability pathways in GD appear warranted, especially with respect to etiological and therapeutic potentials.

Introduction
Adult ADHD diagnosis sometimes represents a challenge for the clinician, due to the comorbid psychiatric diseases that are often associated and which complicate de recognition of the primary symptoms of ADHD. The prevalence of ADHD in adult populations is 2’5% and it is a relevant cause of functional impairment.
ObjectivesPresentation of a clinical case of a male cocaine user diagnosed with adult ADHD.
MethodsLiterature review on adult ADHD and comorbid substance abuse.
ResultsA 43-year-old male who consulted in the Emergency Department due to auditory hallucinosis in the context of an increase in his daily cocaine use. There were not delusional symptoms associated and judgment of reality was preserved. Treatment with olanzapine was started and the patient was referred for consultation. In psychiatry consultations, he did not refer sensory-perceptual alterations anymore, nor appeared any signals to suspect so, and he was willing to abandon cocaine use after a few appointments. He expressed some work concerns, highlighting that in recent months, in the context of a greater workload, he had been given several traffic tickets for “distractions.” His wife explained that he had always been a inattentive person (he forgets important dates or appointments) and impulsive, sometimes interrupting conversations. In the Barkley Adult ADHD Rating Scale he scored 32 points.
He was diagnosed with adult ADHD and treatment with extended-release methylphenidate was started with good tolerance and evolution, with improvement in adaptation to his job and social environment. Since then, the patient has moderately reduced the consumption of drugs, although he continues to use cocaine very sporadically.
ConclusionsEarly detection of ADHD and its comorbidities has the potential to change the course of the disorder and the morbidity that will occur later in adults. Comorbidity in adult ADHD is rather the norm than the exception, and it renders diagnosis more difficult. The most frequent comorbidities are usually mood disorders, substance use disorders, and personality disorders. Treatment of adult ADHD consists mainly of pharmacotherapy supported by behavioral interventions. When ADHD coexists with another disorder, the one that most compromises functionality will be treated first and they can be treated simultaneously. The individual characteristics of each patient must be taken into account to choose the optimal treatment.

Introduction
Subjective memory complaints remain a relevant aspect to be considered in patients with mild cognitive impairment. Likewise, their association with depressive symptoms, quality of life and cognitive performance is also an objective to be studied in such patients.
ObjectivesOur clinical case represents just one opportunity to study how memory complaints are related to depressive states and how they affect the quality of life of patients with mild cognitive impairment.
MethodsWe conducted a bibliographical review by searching for articles in Pubmed.
ResultsPERSONAL HISTORY: Male, 73 years old, separated, residing alone in Valladolid. He has home help, a person comes to help him with the household chores. Little social and family circle.
History in Mental HealthHe has a history of an admission in 2013 to this Short Hospitalization Unit for ethanol detoxification. Since then, he has been followed up in the Mental Health Unit. According to the reports, he has been diagnosed with depressive disorder and cluster B personality disorder.
Current psychopharmacological treatment: diazepam, olanzapine, duloxetine 60 mg, quetiapine.
Toxic habits: history of chronic ethanol consumption. Smoker. He denies other toxic habits.
Current EpisodeThe patient presents a worsening of his mood of 15 days of evolution, coinciding with a voluntary decrease of his psychopharmacological treatment that the patient has carried out on his own. He walks with the aid of a crutch. Hypomimic facies. Slowed language, circumstantial, with speech focused on current discomfort.
On assessment, he reports initial improvement after reducing his medication, but in recent days he has experienced a decrease in initiative accompanied by feelings of emptiness, sadness and loneliness. He refers to memory complaints for which he is awaiting evaluation by Neurology. The patient explains that at other times in his life he has presented self-harming ideas that he has been controlling. At this time he expresses desire for improvement and adequate future plans, and accepts plans to attend a memory workshop. He also reports visual hallucinations with no affective repercussions and preserved judgment of reality.
Therapeutic PlanTreatment adjustment: Duloxetine 60 mg, 2cp/day. The patient is recommended to lead an active lifestyle and attend a day center or memory workshop.
ConclusionsIn numerous patients with mild cognitive impairment, we have observed that memory complaints are closely related to depressive symptoms and to the patient’s functioning in daily life.
In one study memory complaints were a negative predictor of quality of life in these patients.
Therefore, in addition to considering the importance of treating depressive symptoms, it is also important to address quality of life in patients with mild cognitive impairment.
