The maned wolf Chrysocyon brachyurus, the fourth largest canid, is categorized as Near Threatened on the IUCN Red List. The objectives of this study were to update information on the occurrence of this species in Argentina, compare the current distribution to that previously described for 1988–2008, and indicate the areas in which the species is exposed to particular hazards. We created a database that included 1,051 new records of C. brachyurus for 2009-2021, in addition to records for 1988–2008 that had not been reported previously. We calculated the area of occupancy of the species in Argentina to be 500,000 km2. Most of the new records of C. brachyurus are in the Chaco Seco, Espinal and Pampas ecoregions. Our findings indicate a current area of occupancy 61% higher than that calculated from records for 1988–2008. However the location and frequency of reported threats and the intense environmental transformation that characterizes the areas for which we obtained new records suggest counterintuitive implications for the conservation of the species because of increased human–wildlife interactions. Our study reveals the need for systematic research to improve the understanding of the ecological processes that affect the maned wolf in Argentina, and will aid in the development of conservation strategies for the species.
Prehistoric shell mounds can be useful for the quantification of the radiocarbon marine reservoir effect (MRE) and, at the same time, knowledge about the MRE allows for the establishment of robust chronologies for these sites. This creates a loop in which the archaeological setting has a dual role: it is part of both the method and the application. Therefore, it is paramount to address these sites from both archaeological and environmental perspectives, investigating their origin and diagenesis in order to overcome biases caused by post-depositional alterations. In this study, samples of bone, charcoal and shell from a Late Holocene shell mound in Southern Brazil, the Sambaqui de Cabeçuda, were analyzed following a multidisciplinary approach to disentangle the complex relationships between archaeology and the environment. We performed X-ray diffraction, radiocarbon dating, stable isotopes (δ13C, δ18O, δ15N) and anthracology analyses as well as Bayesian Chronological Models and Isotope Mixing Models to assess the local MRE and to reconstruct the diet of Cabeçuda builders. Our results reveal a negative local correction for the MRE (ΔR = –263 ± 46 14C yr), expected for the lagoon next to the site, and diets with considerable intakes of marine proteins. We examine the implications of these results for the chronology of the site and discuss a series of complications when performing MRE studies using shell mound sites.
Understanding deviations from typical brain development is a promising approach to comprehend pathophysiology in childhood and adolescence. We investigated if cerebellar volumes different than expected for age and sex could predict psychopathology, executive functions and academic achievement.
Methods
Children and adolescents aged 6–17 years from the Brazilian High-Risk Cohort Study for Mental Conditions had their cerebellar volume estimated using Multiple Automatically Generated Templates from T1-weighted images at baseline (n = 677) and at 3-year follow-up (n = 447). Outcomes were assessed using the Child Behavior Checklist and standardized measures of executive functions and school achievement. Models of typically developing cerebellum were based on a subsample not exposed to risk factors and without mental-health conditions (n = 216). Deviations from this model were constructed for the remaining individuals (n = 461) and standardized variation from age and sex trajectory model was used to predict outcomes in cross-sectional, longitudinal and mediation analyses.
Results
Cerebellar volumes higher than expected for age and sex were associated with lower externalizing specific factor and higher executive functions. In a longitudinal analysis, deviations from typical development at baseline predicted inhibitory control at follow-up, and cerebellar deviation changes from baseline to follow-up predicted changes in reading and writing abilities. The association between deviations in cerebellar volume and academic achievement was mediated by inhibitory control.
Conclusions
Deviations in the cerebellar typical development are associated with outcomes in youth that have long-lasting consequences. This study highlights both the potential of typical developing models and the important role of the cerebellum in mental health, cognition and education.
The home-field advantage (HFA) hypothesis establishes that plant litter decomposes faster at ‘home’ sites than in ‘away’ sites due to more specialized decomposers acting at home sites. This hypothesis has predominantly been tested through ‘yes or no’ transplanting experiments, where the litter decomposition of a focal species is quantified near and away from their conspecifics. Herein, we evaluated the occurrence and magnitude of home-field effects on the leaf litter decomposition of Myrcia ramuliflora (O.Berg) N. Silveira (Myrtaceae) along a natural gradient of conspecific litterfall input and also if home-field effects are affected by litter and soil traits. Litter decomposition of M. ramuliflora was assessed through litterbags placed in 39 plots in a tropical heath vegetation over a period of 12 months. We also characterized abiotic factors, litter layer traits, and litter diversity. Our results indicated the occurrence of positive (i.e. Home-field advantage) and negative (i.e. Home-field disadvantage) effects in more than half of the plots. Positive and negative effects occurred in a similar frequency and magnitude. Among all predictors tested, only the community weighted mean C/N ratio of the litterfall input was associated with home-field effects. Our results reinforce the lack of generality for home-field effects found in the literature and thus challenge the understanding of litter-decomposer interaction in tropical ecosystems.
Little is known about how conspiracy beliefs and health responses are interrelated over time during the course of the coronavirus disease 2019 (Covid-19) pandemic. This longitudinal study tested two contrasting, but not mutually exclusive, hypotheses through cross-lagged modeling. First, based on the consequential nature of conspiracy beliefs, we hypothesize that conspiracy beliefs predict an increase in detrimental health responses over time. Second, as people may rationalize their behavior through conspiracy beliefs, we hypothesize that detrimental health responses predict increased conspiracy beliefs over time.
Methods
We measured conspiracy beliefs and several health-related responses (i.e. physical distancing, support for lockdown policy, and the perception of the coronavirus as dangerous) at three phases of the pandemic in the Netherlands (N = 4913): During the first lockdown (Wave 1: April 2020), after the first lockdown (Wave 2: June 2020), and during the second lockdown (Wave 3: December 2020).
Results
For physical distancing and perceived danger, the overall cross-lagged effects supported both hypotheses, although the standardized effects were larger for the effects of conspiracy beliefs on these health responses than vice versa. The within-person change results only supported an effect of conspiracy beliefs on these health responses, depending on the phase of the pandemic. Furthermore, an overall cross-lagged effect of conspiracy beliefs on reduced support for lockdown policy emerged from Wave 2 to 3.
Conclusions
The results provide stronger support for the hypothesis that conspiracy beliefs predict health responses over time than for the hypothesis that health responses predict conspiracy beliefs over time.
Anorexia nervosa is an eating behavior disorder that is often related to various personality factors. The relationship between obsessive compulsive disorder and eating Disorders has been highlighted.
Objectives
To present a clinical case of a patient with eating disorder and gastric bezoar, secondary to compulsive hair ingestion.
Methods
Bibliographic review of articles published in relation to the comorbidity of these disorders, based on articles published in the last 5 years in Pubmed.
Results
26-year-old female. Diagnosis of restrictive anorexia nervosa. She was admitted to the hospital on two occasions for nutritional disorders. In the last admission, she reported greater anxiety and significant weight loss. She reports that she has limited her food intake, but she does feel thin and is unable to eat for fear of gaining weight. Ruminative thoughts about her body image. During admission, the patient expressed a sensation of fullness, nausea and vomiting, later observing in abdominal X-ray and gastroscopy, the presence of a gastric trichobezoar, which was finally resolved conservatively.
Conclusions
Trichotillomania is observerd in 1 in 2000 people, trichophagia is even less frequent. According to DSM-
V, these disorders are grouped within obsessive-compulsive spectrum disorders. A Trichobezoar is a conglomerate that can be found in the stomach or intestine, composed mainly of hair, previously ingested. Trichotillomania can be associated with anorexia nervosa, especially in patients with obsessive personality traits, which occurs frequently. The gastric slowing that patients with anorexia often present is a factor that favors the formation of the bezoar
Valproic acid is an antiepileptic drug used in different fields of Psychiatry. It is known mostly for its use in managing patients with bipolar affective disorder. In psychiatry of addiction, there is still no approved indications for its usage, but it is widely prescribed in treating alcohol and cocaine abuse, due to the existence of studies in these addictions.
Objectives
This review aims to clarify the relation between valproic acid and dependences, particularly cocaine.
Methods
Non-systematic literature review using a PubMed search, using the following key words: “valproate”; “cocaine use”.
Results
Cocaine dependence can decrease GABA levels in humans. Valproic acid has multiple mechanisms that favour the synthesis of GABA, potentiating its release and postsynaptic GABAergic response. Because of this, valproic acid was found effective in promoting abstinence and in reducing the use of cocaine. There are studies that support the valproic acid’s use in alcohol and cocaine dependences. Valproic acid has been shown to be promising in relapse prevention. It has also showed efficacy in the management of impulsivity and irritability, what makes it useful in managing patients with borderline personality disorder – patients at higher risk for alcohol or substance use disorders.
Conclusions
Cocaine addiction involves different phenomena and may respond to distinct pharmacologic approaches. Although some studies need to be confirmed by larger clinical trials, valproic acid seems a promising agent as one of some potential treatments for cocaine dependence. Further studies are required in this field to come to more reliable conclusions.
The harmful use of alcohol is an important risk factor for the health of the population around the world. The incidence of alcohol dependence in women is increasing and both its consumption pattern and its consequences have unique characteristics.
Objectives
To present a literature review focused on alcohol use disorder with a gender perspective.
Methods
Literature review.
Results
- Women use to start using alcohol sooner than men and this seems to be a risk factor to become addicted. - Due to physiological and psychological factors women experience more negative health effects from excessive alcohol use than men and it occurs at lower levels of use. - Psychiatric comorbidity associated with alcohol abuse such as anxiety and depression is more common in women and this in turn worsens the alcohol use disorder. - Alcohol consumption increases the vulnerability of women on several levels, including an increased risk of physical abuse.
Conclusions
Alcohol abuse among women deserves special attention and a specific intervention focused on the gender perspective.
Electroconvulsive therapy (ECT) is a medical treatment for those patients with high suicide risk or refractory psychiatric disorders. It is currently a safe technique, and its effectiveness has been widely demonstrated.
Objectives
Presentation of a clinical case about a patient with drug-resistant delusional disorder and high suicide risk, who eventually received ECT treatment.
Methods
Bibliographic review including the latest articles in Pubmed about ECT procedure, effects and use.
Results
We present a 45-year-old man, who visited different doctors several times by reporting he had the feeling of “having a brain tumor or a vascular disorder”, so he requested imaging tests (computed tomography and magnetic resonance). These tests were absolutely normal, but he kept thinking something was wrong, and eventually attempted suicide by hanging (his family founded him before it was too late). The patient was admitted to hospital, and started psychopharmacological treatment, with minimal response. He desperately insisted that he had “something inside his head”. At this point, it was proposed to start ECT, and the patient accepted. After 6 bilateral ECT sessions, he was visibly more relaxed and less worried, and he no longer presented autolytic ideation. He was still a little bit suspicious about the feeling of having a neurological disease. Currently, the patient runs a follow-up consultation.
Conclusions
Electroconvulsive therapy is a safe and effective technique for those patients with high suicide risk. It may be useful to perform imaging tests in certain cases, for detecting intracranial pressure, acute hemorrhage, tumors… A follow-up of these patients must be performed
The concept of motivation pervades our professional and personal lives. Motivation is almost impossible to be observed directly, it is a construct for the interpretation of a behaviour that “calls the attention”.
Objectives
This work reviews the current available data on the phenomenological description of motivation and the abnormalities of motivation.
Methods
Non-systematic review of the literature with selection of scientific articles published in the past 10 years; by searching Pubmed and Medscape databases using the combination of MeSH descriptors. The following MeSH terms were used: “motivation”, “psychopathology”, “phenomenology”.
Results
Abnormalities in motivation may involve diminution or exacerbation. Anhedonia is the absence of pleasure in relation to usually pleasurable activities, it occurs in depression and schizophrenia where the pleasurable intrinsic motivation that acts as incentive for behaviour may be lost. In mania it may be increased so that mundane activities become unduly fascinating and rewarding.
Conclusions
Countless theories have been proposed to explain human motivation but each sheds light on specific aspects of motivation, neglecting others. This diversity creates confusion because most theories have areas of conceptual overlap and disagreement. To facilitate the development of studies, an agreement should be achieved on an operational definition of motivation.
Mutism is the inability or unwillingness to speak, resulting in an absence or marked paucity of verbal output. Mutism is a common manifestation of psychiatric, neurological, and drug-related illnesses. Psychiatric disorders associated with mutism include schizophrenia, affective disorders, conversion reactions, dissociative states, and dementias. Neurological disorders causing mutism affect the basal ganglia, frontal lobes, or the limbic system.
Objectives
Outline the importance of setting a differential diagnosis of mutism in the Emergency Room.
Methods
Review of scientific literature based on a relevant clinical case.
Results
Male, 58 years old. He has lived in a residence for 3 months due to voluntary refusal to ingest. Diagnosed with paranoid personality disorder. He is refered to the Emergency Service due to sudden mutism. During this day, he has been stable and suitable with a good functionality. For 3 hours he is mutist, oppositional attitude and stiff limbs, refusing to obey simple orders. Hyperalert and hyperproxia. Not staring. After ruling out organic pathology: normal blood tests, negative urine toxins and cranial CT without alterations, he was admitted to Psychiatry for observation and, finally, he was diagnosed with Psychotic Disorder NOS.
Conclusions
Mutism most often occurs in association with other disturbances in behavior, thought processes, affect, or level of consciousness. The most common disorder of behavior occurring with mutism is catatonia. The differential diagnosis of mutism is complex. In some cases the diagnosis will be clarified only by careful observation and after a neurological evaluation. Published studies show neurological disorders presenting with mutism can be misdiagnosed as psychiatric.
There is a high comorbidity between psychiatric disorders and juvenile myoclonic epilepsy (JME), observed in up to 58% of these patients; specifically, mood disorders, anxiety and personality disorders (PD). In some patients with PD there are nonspecific alterations in the EEG, which nevertheless sometimes involve pathology. The presence of personality disorders along with JME has been repeatedly described. Previous studies have emphasized the difficulties in treating patients with JME, which have been attributed to some specific psychiatric, psychological and psychosocial characteristics.
Objectives
Describing distinctive personality traits in JME
Methods
Review of scientific literature based on a relevant clinical case.
Results
19-year-old woman, single. Psychiatric history since she was 12 due to anxiety-depressive symptoms, after being diagnosed with JME. 4 admissions in Psychiatry, with a variety of diagnoses: eating disorder, attention deficit hyperactivity disorder and borderline personality disorder. The evolution of both disorders has been parallel, presenting epileptic seizures due to irregular therapeutic adherence together with pseudo-seizures, which made difficult their differential diagnosis. In addition, he has had frequent visits to the emergency room for suicide attempts and impulsive behaviors.
Conclusions
In 1957, for the first time, distinctive personality traits were described in patients with JME: lack of control and perseverance, emotional instability, variable self-concept and reactive mood, which have been confirmed in subsequent studies. It is believed as epilepsy progresses, patients tend to develop symptoms of depression, anxiety, social problems, and attention deficit. Therefore, these patients have difficulty in following medical recommendations, especially precautions regarding precipitating factors for seizures.
The Covid-19 pandemic has had a significant impact on the mental health of adolescents. Several descriptive studies and systematic reviews have shown an increase in suicide rates in this age group.
Objectives
- To present a literary review on the impact of the Covid-19 pandemic on the mental health and suicidal behavior of adolescents around the world. - To present data on admission rates due to suicidal behavior during the first year of the Covid-19 pandemic in a Spanish child-adolescent psychiatric hospitalization unit.
Methods
- We will present a literature review and a retrospective cross-sectional study on admission rates for suicidal behavior in a child-adolescent psychiatric hospitalization unit. - Admission rates for suicidal behavior during the year prior to the pandemic will be compared with rates relative to the first year of the pandemic.
Results
- We have found a significant increase in admission rates for suicidal behavior during the year of the pandemic. Similar results have been found in different studies and meta-analyzes. - The socio-demographic characteristics of the patients are quite similar in the two periods of time analyzed, but the reference to intra-family problems has been more frequent in the year of the pandemic.
Conclusions
Our data is in line with other studies suggesting that the Covid-19 pandemic has had a strong impact on teenage suicidal behavior.
Neurocognitive deficits amongst patients with schizophrenia are considered one of schizophrenia’s central features. These deficits appear to be present from the first episode of psychosis (FEP) and certain cognitive impairments could be components of a genetic vulnerability to schizophrenia. Regarding research on cannabis and cognition in schizophrenia, different studies have assessed neurocognitive functions: memory, attention/vigilance, processing speed, verbal learning, executive functions, and verbal fluency.
Objectives
The aim is to do a review of recent findings concerning the association of cannabis use with cognition in schizophrenia.
Methods
A literature review was conducted using the PubMed search database.
Results
Patients with schizophrenia and concomitant cannabis use are associated with worse performance in immediate verbal learning, and in some studies with worse working memory performance. There is an improvement of verbal memory when they cease the cannabis’ consumption. Regarding attention capacity and memory types assessed, the results are controversial. In FEP, heavy cannabis use during the previous year correlates with slower processing speed. Also, FEP-patients with cannabis use but no family history of psychosis perform worse in executive functions, while those with a family history of psychosis perform better.
Conclusions
The studies of psychosis, cannabis and cognition differ in relevant aspects, which might be connected to the result variability. Therefore, before solid conclusions can be reached, it is important to carry out longitudinal studies to understand the changes in the cognitive variables, which can depend on the pattern of cannabis’ use (concurrent or prior to the FEP). Possible confounding variables that might be present should be acknowledged.
Traumatic brain injury (TBI) can cause changes in the personality and behaviors. History of TBI has been associated with violent behavior and substance abuse.
Objectives
Presentation of a clinical case of a patient with antisocial personality traits who suffered a TBI and abuses alcohol.
Methods
We conducted a bibliographic review by searching for articles published the last 5 years in Pubmed
Results
We present the case of a 48-year-old male patient with a history of myoclonic epilepsy, who suffered a TBI in a car crash. During his stay at ICU antisocial and borderline personality traits were found. When he came to consultations, he presented signs of alcohol intoxication (verbiage with hasty and dysarthric speech, and psychomotor incoordination). He acknowledges daily alcohol intake, although he minimizes it. During the interview he is irritable, prone to anger when contradicted and boasts of episodes of heteroaggressiveness and violence that he has carried out in the past. He reports morning sickness and tremors, but does not accept that they may be due to alcohol withdrawal. There is no motivation for change.
Conclusions
It has been determined that history of TBI is more frequent in individuals with antisocial personality. TBI has been linked to violent behaviors, poor inhibitory control, engaging in illegal acts and higher rates of substance abuse. However, the causal relationship between antisocial behavior and TBI has yet to be clarified, as the available evidence does not show which comes first. More research is needed in the future that takes into account the temporal sequence of events.
Migrations are a source of stress for patients, which can have repercussions on their Mental Health. We present the case of a native Senegalese patient who presented a first psychotic episode.
Objectives
Presentation of a clinical case of an immigrant patient with a psychotic disorder.
Methods
Bibliographic review on migration and psychosis by searching for articles in Pubmed.
Results
We present the case of a patient of 20 years, a native of Senegal, who has been living in Spain for 3 months in a shelter home. He has no family or relations in Spain, and only speaks Wolof, presenting serious difficulties in communication with healthcare workers. He came to Hospital with his social worker because strange behaviors had been observed. He presented delusional ideation of self-referential and mystical-religious content, related to “the prophet” and “the need to fulfill a mission”. He also presented auditory hallucinations that he identified as of divine origin, and ordered him to perform behaviors such as picking hairs from the ground and various rituals. He acknowledges cannabis and alcohol use in the previous days. Paliperidone treatment was started. Throughout the admission, he begins to show concern for the state of his relatives in Senegal and the need to send them money.
Conclusions
Multiple studies indicate that migrants are at higher risk of psychosis, specially those from countries where the majority of population was black, according to some series. The challenge lies in understanding the mechanisms underlying this increased incidence, taking into account psychosocial factors such as social isolation and trauma.
There are life events that may increase the possibilities of suffering some kind of Psychopathology. The most validated model for understanding the aetiology of psychosis is based on genetic and environmental risk factors and their interaction, likely involving epigenetic mechanisms. It is necessary to consider those events as risk factors for Mental Health.
Objectives
Study of risk and prognostic factors in psychosis.
Methods
Review of scientific literature based on a relevant clinical case.
Results
We present the case of a 28-year-old male patient from Peru, currently living in Germany. History of sexual abuse in childhood. He started taking drugs at the age of 8. In the emergency department, he reports that since the beginning of the pandemic, after listening to a speech by the Pope, he begins to interpret signals about situations occurring around him. He begins to read about mystical-religious subjects, changes the style of music he listens to and recognises changes in his personality. He says for months he has been feeling watched, persecuted and expresed someone wants to kill him. He says hears voices and that they communicate with him through bodily sensations.
Conclusions
Childhood trauma, immigration and cannabis use are significantly associated with an increased risk of functional psychosis. A neurotic personality also independently contributes to this risk. The accumulation of these factors increases vulnerability to mental disorders and leads to a worse prognosis and evolution of these pathologies. These findings could help to improve the prevention of psychosis and the development of specific treatment strategies in this particular population.
Seizures occur in about 3% cases of alcohol withdrawal. They usually appear within 48 hours after abrupt cessation, and are characterized by a reduction in seizure threshold secondary to adaptation to alcohol. More than 50% of individuals will experience a new seizure and in 5% of these cases, progression to a sustained epilepticus status can occur.
Objectives
The aim is to do a review of the literature on alcohol withdrawal and the onset of seizures in individuals with alcohol addiction.
Methods
A literature review was conducted using the PubMed search database.
Results
Alcohol is a central nervous system (CNS) depressant and chronic consumption causes neuroadaptation in order to maintain homeostasis. This adaptation involves the upregulation of excitatory neurotransmitters systems and the downregulation of inhibitory ones. When consumption is abruptly discontinued, the depressive contribution of alcohol to a previously established balance is disrupted, resulting in withdrawal symptoms associated to a generalized CNS’ hyperexcitability state.Critical episodes increase the risk of delirium tremens, a fatal condition in 20% of untreated cases. Thus, the treatment and prevention of seizure recurrences is essential: the clinical guidelines of the American Society of Addiction Medicine 2020, offer an action proposal. Pharmacological therapy after seizures is the preferential treatment: intravenous administration of fast-acting benzodiazepines (lorazepam and diazepam) is the first line treatment.
Conclusions
It is essential to monitor signs and symptoms that alert us to the appearance of seizures associated to alcohol withdrawal, effectively treat these cases, prevent recurrences, and provide a quality follow-up for these patients.
Body dysmorphic disorder (BDD) is a relatively common disorder characterized by a preoccupation with non-existent or slight defects in appearance. It was first described in 1886 by Morselli as dysmorphophobia.
Objectives
This work reviews the current available data on BDD and its treatment options and describes a clinical case that reports an improvement in symptomatology after surgery.
Methods
Non-systematic review of the literature with selection of scientific articles published in the past 10 years; by searching Pubmed and Medscape databases using the combination of MeSH descriptors. The following MeSH terms were used: “body dysmorphic disorder”, “dysmorphophobia”. Clinical file consultation.
Results
The usual treatment involves a combination of psychotherapy and pharmacotherapy. Antidepressant medication, mainly selective serotonin reuptake inhibitors (SSRIs) have been used. If the symptoms do not improve, a different SSRI can be considered or clomipramine, venlafaxine or second-generation antipsychotics can be useful.
Conclusions
The role of surgery remains controversial, several studies indicating that the symptoms typically worsen after an aesthetic procedure because the preoccupation shifts to a different body area. However a recent study reported 32 of the 41 patients that underwent surgery were highly satisfied with the outcome. In our clinical case, our patient, a 20-year-old female with non-delusional dysmorphic ideas about her nose initiated treatment with paroxetine with poor response and was, against medical opinion, submitted to a rhinoplasty. Three weeks after the surgery there was an improvement in preoccupation about her nose. More research should be made to clarify the role of surgery in this disorder that often lacks adequate therapeutical response.
Suicide rates in people diagnosed with a psychotic disorder can be up to 50 times higher than in the general population, with the lethality of attempts being significantly higher in this group, compared to people diagnosed with other psychiatric disorders. Furthermore, it is known that being male is associated with more serious suicide attempts and higher rates of completed suicides.
Objectives
To reflect on the increased risk of suicide associated with psychotic disorders.
Methods
Case report and literature review.
Results
Case report 40-year-old male, recently diagnosed with Schizophreniform Disorder and currently with persistent positive symptoms. He was admitted to our psychiatric hospitalization unit due to a voluntary overdose of almost 100 tablets (antihypertensives, antiarrhythmics, and benzodiazepines) and alcohol. He admits taking the pills with the aim of committing suicide. Literature review: - Around 10% of people diagnosed with schizophrenia commit suicide. - In young patients diagnosed with schizophrenia, suicide is the leading cause of death. - Between 15 and 65% of patients diagnosed with schizophrenia have depressive symptoms such as hopelessness. - Depressive symptoms in these patients seem to be directly proportionally with awareness of the disease (stigma, awareness of its severity and a sudden decrease in quality of life and social integration). - The risk of suicide increases especially in the first 10 years of the disease.
Conclusions
Psychosis is an important risk factor of suicide and active preventive measures should be carried out in these patients.
