RESUMO

This review summarizes the literature data reported from 2000 up to the present on the development of various electrochemical (voltammetric, amperometric, potentiometric and photoelectrochemical), optical (UV-Vis and IR) and luminescence (chemiluminescence and fluorescence) methods and the corresponding sensors for rifamycin antibiotics analysis. The discussion is focused mainly on the foremost compound of this class of macrocyclic drugs, namely rifampicin (RIF), which is a first-line antituberculosis agent derived from rifampicin SV (RSV). RIF and RSV also have excellent therapeutic action in the treatment of other bacterial infectious diseases. Due to the side-effects (e.g., prevalence of drug-resistant bacteria, hepatotoxicity) of long-term RIF intake, drug monitoring in patients is of real importance in establishing the optimum RIF dose, and therefore, reliable, rapid and simple methods of analysis are required. Based on the studies published on this topic in the last two decades, the sensing principles, some examples of sensors preparation procedures, as well as the performance characteristics (linear range, limits of detection and quantification) of analytical methods for RIF determination, are compared and correlated, critically emphasizing their benefits and limitations. Examples of spectrometric and electrochemical investigations of RIF interaction with biologically important molecules are also presented.

RESUMO

One of the most complex and challenging developments at the beginning of the third millennium is the alarming increase in demographic aging, mainly-but not exclusively-affecting developed countries. This reality results in one of the harsh medical, social, and economic consequences: the continuously increasing number of people with dementia, including Alzheimer's disease (AD), which accounts for up to 80% of all such types of pathology. Its large and progressive disabling potential, which eventually leads to death, therefore represents an important public health matter, especially because there is no known cure for this disease. Consequently, periodic reappraisals of different therapeutic possibilities are necessary. For this purpose, we conducted this systematic literature review investigating nonpharmacological interventions for AD, including their currently known cellular and molecular action bases. This endeavor was based on the PRISMA method, by which we selected 116 eligible articles published during the last year. Because of the unfortunate lack of effective treatments for AD, it is necessary to enhance efforts toward identifying and improving various therapeutic and rehabilitative approaches, as well as related prophylactic measures.

RESUMO

Background and Objectives: The informal caregiver's contribution to the wellbeing of dementia patients is critical since these individuals become dependent on others for all daily activities. Our goal was to investigate the dynamics of anxiety, depression, burnout, sleep, and their influence on quality of life over a 6-month period in the context of pandemic distress in a sample of informal caregivers of Alzheimer's patients. Materials and Methods: For this prospective, longitudinal study, we conducted a 6-month telephonic survey between 2021 and 2022, administering a series of questionnaires at three timepoints (baseline, 3 months and 6 months) to a group of informal caregivers of patients suffering from dementia due to Alzheimer's disease. Results: A total of 110 caregivers were included at baseline, out of which 96 continued to the second stage and 78 followed through to the last stage. The majority of the participants were female (most likely the patients' daughters), around 55 years old, living in urban areas, married, with children, having a high school degree or a higher education degree, and working in jobs that required physical presence; in the best-case scenario, they were sharing their responsibilities with another two-three caregivers. More than half of the 110 participants (50.9%) reported mild to moderate anxiety at baseline, and 27.3% reported significant anxiety, with no changes between the three timepoints, F(2, 154) = 0.551, p = 0.57; 25% reported moderate-severe depression at the start, with no changes between the three timepoints, F(2, 154) = 2.738, p = 0.068; and many reported a decrease in quality of life, poor quality of sleep, and decreased fear of COVID infection. Cynicism, professional effectiveness, anxiety, depression, and sleep quality explained up to 87.8% of the variance in quality of life. Conclusions: Caregivers' decreased quality of life during the pandemic was explained by their levels of burnout, anxiety, and depression throughout the 6-month period.

RESUMO

Chorea is a hyperkinetic movement disorder, accompanied by dystonia, myoclonus, tics, stereotypies, and tremors. It is characterized by excessive, purposeless movements that are distressing, irregularly timed, and randomly distributed. Chorea can be present in many diseases, such as hereditary, metabolic disturbance, drug-induced, and functional disorders, and, rarely, genetic, autoimmune, and infectious diseases. Primary myelofibrosis (PMF) is a myeloproliferative neoplasm that leads to ineffective clonal hematopoiesis, fibrous tissue deposits in the bone marrow, extramedullary hematopoiesis, and splenomegaly. In rare cases, following uncertain pathological mechanisms, it can present with chorea, particularly affecting the limbs, head, and orofaciolingual muscles. We present a case of a male patient with evolving PMF over several years who was admitted for progressive cognitive impairment and generalized involuntary movement disorder. We also present a review of all cases of myeloproliferative disorders presenting with chorea published in the last 40 years.

RESUMO

Background and Objectives: The association between myasthenia gravis (MG) and depression is intricate and characterized by bidirectional causality. In this regard, MG can be a contributing factor to depression and, conversely, depression may worsen the symptoms of MG. This study aimed to identify any differences in the progression of the disease among patients with MG who were also diagnosed with depression as compared to those without depression. Our hypothesis focused on the theory that patients with more severe MG symptoms may have a higher likelihood of suffering depression at the same time. Materials and Methods: One hundred twenty-two male and female patients (N = 122) aged over 18 with a confirmed diagnosis of autoimmune MG who were admitted to the Neurology II department of Myasthenia Gravis, Clinical Institute Fundeni in Bucharest between January 2019 and December 2020, were included in the study. Patients were assessed at baseline and after six months. The psychiatric assessment of the patients included the Hamilton Depression Rating Scale-17 items (HAM-D), and neurological status was determined with two outcome measures: Quantitative Myasthenia Gravis (QMG) and Myasthenia Gravis Activities of Daily Life (MG-ADL). The patients were divided into two distinct groups as follows: group MG w/dep, which comprised 49 MG patients diagnosed with depressive disorder who were also currently receiving antidepressant medication, and group MG w/o dep, which consisted of 73 patients who did not have depression. Results: In our study, 40.16% of the myasthenia gravis (MG) patients exhibited a comorbid diagnosis of depression. Among the MG patients receiving antidepressant treatment, baseline assessments revealed a mean MG-ADL score of 7.73 (SD = 5.05), an average QMG score of 18.40 (SD = 8.61), and a mean Ham-D score of 21.53 (SD = 7.49). After a six-month period, a statistically significant decrease was observed in the MG-ADL (2.92, SD = 1.82), QMG (7.15, SD = 4.46), and Ham-D scores (11.16, SD = 7.49) (p < 0.0001). These results suggest a significant correlation between MG severity and elevated HAM-D depression scores. Regarding the MG treatment in the group with depression, at baseline, the mean dose of oral corticosteroids was 45.10 mg (SD = 16.60). Regarding the treatment with pyridostigmine, patients with depression and undergoing antidepressant treatment remained with an increased need for pyridostigmine, 144.49 mg (SD = 51.84), compared to those in the group without depression, 107.67 mg (SD = 55.64, p < 0.001). Conclusions: Our investigation confirms that the occurrence of depressive symptoms is significantly widespread among individuals diagnosed with MG. Disease severity, along with younger age and higher doses of cortisone, is a significant factor associated with depression in patients with MG. Substantial reductions in MG-ADL and QMG scores were observed within each group after six months, highlighting the effectiveness of MG management. The findings suggest that addressing depressive symptoms in MG patients, in addition to standard MG management, can lead to improved clinical outcomes.

RESUMO

In the last few years, vitamin D functions have been studied progressively, and along with their main role in regulating calcium homeostasis, the potential function in the nervous system and the link between different psychiatric disorders and vitamin D deficiency have been revealed. The discovery of vitamin D receptors in multiple brain structures, like the hippocampus, led to the hypothesis that vitamin D deficiency could be responsible for treatment resistance in psychiatric diseases. The aim of this study was to analyze the current knowledge in the literature regarding vitamin D deficiency among individuals afflicted with psychiatric disorders and assess the potential therapeutic benefits of vitamin D supplementation. A systematic search was conducted on the PubMed database for articles published in the last five years (2016-2022) in English, focusing on human subjects. Results show that vitamin D deficiency has implications for numerous psychiatric disorders, affecting mood and behavior through its influence on neurotransmitter release, neurotrophic factors, and neuroprotection. It also plays a role in modulating inflammation, which is often elevated in psychiatric disorders. In conclusion, vitamin D deficiency is prevalent and has far-reaching implications for mental health. This review underscores the importance of exploring the therapeutic potential of vitamin D supplementation in individuals with psychiatric disorders and highlights the need for further research in this complex field.

RESUMO

In recent years, escitalopram (ESC) has been suggested to have different mechanisms of action beyond its well known selective serotonin reuptake inhibition. The aim of this study is to investigate the effects of escitalopram on oxidative stress, apoptosis, brain-derived neurotrophic factor (BDNF), Methyl-CpG-binding protein 2 (MeCP2), and oligodendrocytes number in the brain of chronic unpredictable mild stress-induced depressed rats. The animals were randomised in four groups (8 in each group): control, stress, stress + ESC 5 and stress + ESC 5/10. ESC was administered for 42 days in a fixed dose (5 mg/kg b.w.) or in an up-titration regimen (21 days ESC 5 mg/kg b.w. then 21 days ESC 10 mg/kg b.w.). Sucrose preference test (SPT) and elevated plus maze (EPM) were also performed. ESC improved the percentage of sucrose preference, locomotion and anxiety. ESC5/10 reduced the oxidative damage in the hippocampus and improved the antioxidant defence in the hippocampus and frontal lobe. ESC5/10 lowered caspase 3 activity in the hippocampus. Escitalopram had a modulatory effect on BDNF and the number of oligodendrocytes in the hippocampus and frontal lobe and also improved the MeCP2 expressions. The results confirm the multiple pathways implicated in the pathogenesis of depression and suggest that escitalopram exerts an antidepressant effect via different intricate mechanisms.

RESUMO

Intra-lysosomal accumulation of the autofluorescent "residue" known as lipofuscin, which is found within postmitotic cells, remains controversial. Although it was considered a harmless hallmark of aging, its presence is detrimental as it continually accumulates. The latest evidence highlighted that lipofuscin strongly correlates with the excessive production of reactive oxygen species; however, despite this, lipofuscin cannot be removed by the biological recycling mechanisms. The antagonistic effects exerted at the DNA level culminate in a dysregulation of the cell cycle, by inducing a loss of the entire internal environment and abnormal gene(s) expression. Additionally, it appears that a crucial role in the production of reactive oxygen species can be attributed to gut microbiota, due to their ability to shape our behavior and neurodevelopment through their maintenance of the central nervous system.

RESUMO

Schizophrenia is a severe, chronic neuropsychiatric disorder characterized by symptoms that profoundly impact behavior, cognition, perception, and emotions, leading to a reduced quality of life and physical impairment. Given the complexity of schizophrenia, there is a pressing need for clinical markers and tools to predict its course, enhance disease staging, facilitate early intervention, improve differential diagnosis, and tailor individualized treatment approaches. Previous studies focused on the relationship between neurological soft signs (NSS) and factors such as age, illness duration, and symptomatology, indicating NSS as state markers improving in parallel with psychotic symptom remission or predicting treatment resistance. However, there is a lack of consensus on NSS assessment tools, hindering routine clinical monitoring despite diagnostic and prognostic potential. The present longitudinal study involved 81 psychiatric inpatients diagnosed with schizophrenia. Patients were assessed at three time points: baseline, 1 month, and 6 months. The examination included the use of scales to evaluate psychotic and neurological symptoms, as well as the identification of adverse extrapyramidal reactions caused by neuroleptic treatment. The progression of NSS was correlated to both the symptomatology and the sociodemographic data of the patients. The main findings from the present investigation revealed a statistical correlation between NSS and psychopathological symptoms, especially with negative symptoms of schizophrenia. However, it is important to note that neuroleptic side effects only had a limited impact on NSS. Therefore, instead of being linked to extrapyramidal symptoms caused by neuroleptics, NSS appears to be more frequently related with symptoms of schizophrenia. Our findings provide further support for their strong association with the course of schizophrenia, independent of treatment side effects, thus emphasizing their potential as reliable assessment tools in both research and clinical settings.

RESUMO

Alien hand syndrome (AHS) is an uncommon neurological condition characterized by involuntary, yet seemingly purposeful, movements of a limb, typically an upper extremity, with variable awareness and control by the affected individual. It is associated with a range of peculiar sensations, such as the feeling of limb estrangement, alien control and involuntary mirroring or restraining of movements. AHS indicates a profound disruption in volitional motor control and personal agency. The aetiology of AHS is the dysfunction of critical brain regions secondary to diverse neurological insults, such as tumours, vascular disorders, infarction or neurodegenerative diseases. It is clinically categorized into the parietal and callosal types, depending on the affected region, with manifestations often linked to the specific brain region affected. The callosal type is particularly challenging to diagnose due to its rarity and potential for nonspecific or concealed symptoms amid concurrent brain injuries. Distinguishing AHS from psychiatric disorders is crucial for accurate diagnosis and improved patient outcomes. Further research is imperative for a deeper understanding of the pathophysiology of AHS and the development of effective treatments. AHS predominantly affects adults and is frequently associated with multiple comorbidities. The syndrome is also exemplified by three distinct motor behaviours: Involuntary grasping, inter-manual conflict and limb levitation accompanied by the sensation of an alien limb or the perception of external control over one's movements. It has a generally good prognosis with partial or total recovery following appropriate rehabilitation techniques, including pharmacological and psychological measures.

RESUMO

The aim of this analysis was to investigate the socio-demographic and clinical profile, the effectiveness, and the association of pharmacological treatment in patients who underwent electroconvulsive therapy during the last 10 years in the largest psychiatric hospital in Romania. This study includes 249 patients aged between 18 and 73 years old. Recurrent depression was the most frequent diagnosis for which ECT was performed (T = 96, 38.55%), followed by schizophrenia (T = 72, 28.91%). The most frequent indication for ECT was treatment resistance (T = 154, 61.84%), followed by persistent suicidal ideation (T = 54, 21.68%) and catatonia (T = 42, 16.86%). In 111 (44.60%) cases included in this study, re-hospitalization was required after performing ECT, while 138 (55.40%) participants did not require any further hospital readmissions. Significant differences were found between these groups in terms of socio-demographic data, diagnosis, number of ECT sessions performed, and association of psychotropic medication during and after the procedure, therefore two separate patient profiles were found based on these characteristics. Patients necessitating re-hospitalization post-ECT were mainly males aged 25-44 diagnosed with schizophrenia and underwent a greater number of ECT sessions (7-12), whereas those not requiring re-hospitalization were predominantly females aged 45-64 with recurrent depressive disorder for which 4-6 ECT sessions were performed.

RESUMO

(1) Background: Neurological Soft Signs (NSS) are subtle neurological abnormalities that are more common in schizophrenia patients than in healthy individuals and have been regularly observed in neuroleptic-naive first-episode patients, supporting the hypothesis that they are an intrinsic component of schizophrenia. (2) Methods: a review of articles published in the last ten years (from January 2013 to January 2023) was carried out on articles published in ScienceDirect and PubMed, by following the PRISMA Statement extension for scoping reviews (PRISMA-ScR), which evaluated the impact of NSS in correlation with the symptomatology, neuroleptic treatment, and the cerebral structural changes of patients with schizophrenia. (3) Results: thirty articles were included, among them twelve included MRI structural evaluation and four studies with a longitudinal design. (4) Conclusions: interest in researching NSS has increased in recent years, but questions remain about their origin and relationship to schizophrenia symptoms, thus this study aims to fill in information gaps in the hope that future research will help provide individualized treatment. It is suggested that NSS in schizophrenia might have an inherited genetic relationship pattern, thus being in line with a trait viewpoint. Most of the research revealed that schizophrenia patients had higher NSS scores than healthy controls, however, they were rather similar to their first-degree relatives, thus, also arguing in favor of a trait perspective. The greatest improvement in scores is seen in those with a remitting course, as shown by declining NSS ratings concurrent with symptomatology.

RESUMO

The coronavirus pandemic has had a global impact on both mental and physical health. Caregiving has become more difficult during this time due to the quick spread of this respiratory disease, dread of the unknown, congested hospitals, and many restrictions, particularly for people with multiple comorbidities. We aimed to assess the impact of this pandemic on a group of caregivers of patients with dementia and their needs during this time. The study's findings indicate that females assumed the role of the caregiver more often than men (88.5% of the participants) and scored lower on the life quality scale. The most often issue encountered during the pandemic was difficulty in accessing health care facilities (36%). Participants with a higher education level scored better in the physical (24.67, p = 0.01 and 24.48, p = 0.01) and mental health (20.67, p = 0.002; 19,82, p = 0.008) domains of the life quality test. The fear of COVID questionnaire showed a low level of concern in the category of participants with a high education level. Overall, this pandemic emphasizes the importance of social interaction and the possibilities to improve health care services through telemedicine. Caregivers could benefit from socialization and support programs as well as the early detection of affective disorders.

RESUMO

The COVID-19 pandemic resulted in a global sanitary crisis and, in addition, elicited serious mental health consequences. The utilization of psychiatric hospital-based services acts as an indicator of public mental health. Therefore, this research sought to investigate differences in the numbers and characteristics of inpatient admissions for psychotic and affective disorders at the largest Romanian psychiatric hospital between the period of lockdown (16 March−15 May 2020) and another three corresponding periods: the same year in the pre-lockdown period (16 January−15 March 2020), the immediate post-lockdown period (16 May−15 July 2020), and two years later (16 March−15 May 2022). A retrospective analysis was performed. The study included a total of 6604 patients. Inpatient admissions decreased during lockdown in comparison with the pre-lockdown period and immediate post-lockdown period for psychotic disorders (p < 0.001 and p < 0.001, respectively) and affective disorders (p < 0.001 and p < 0.001, respectively). For both psychotic and affective disorders, a decrease in the age of the patients admitted during lockdown, as compared with the pre-lockdown period (p < 0.05 and p < 0.001, respectively), was observed. The length of the hospital stay for affective disorders was higher immediately post-lockdown in comparison with the lockdown period (p < 0.001). Collectively, the present findings provide a glimpse of the immediate and long-term consequences of the COVID-19 pandemic and lockdown measures on patients' access to mental healthcare in the form of hospitalization, and these findings could provide the basis for the development of a different approach to times of crisis.

RESUMO

A simple and rapid differential pulse voltammetric (DPV) method using a single-use electroactivated pencil graphite electrode (PGE*) is proposed for the rapid screening of the total content of polyphenolics (TCP) with intermediate antioxidant power (AOP) in grapefruit peel and fresh juice. The results were compared and correlated with those provided by the HPLC-DAD-MS method. NG voltammetric behavior at PGE* was studied by cyclic voltammetry and an oxidation mechanism was suggested. The experimental conditions (type of PGE, electroactivation procedure, pH, nature and concentration of supporting electrolyte) for NG DPV determination were optimized. The NG peak current varied linearly with the concentration in the ranges 1.40 × 10-6-2.00 × 10-5 and 2.00 × 10-5-1.40 × 10-4 mol/L NG and a limit of detection (LoD) of 6.02 × 10-7 mol/L NG was attained. The method repeatability expressed as relative standard deviation was 7.62% for the concentration level of 2.00 × 10-6 mol/L NG. After accumulation for 240 s of NG at PGE* the LoD was lowered to 1.35 × 10-7 mol/L NG, the linear range being 6.00 × 10-7-8.00 × 10-6 mol/L NG. The developed electrochemical system was successfully tested on real samples and proved to be a cost-effective tool for the simple estimation of the TCP with intermediate AOP in citrus fruits.

RESUMO

Objective: Several small clinical trials have reported that the dopamine agonist pramipexole was beneficial in treating patients with schizophrenia. A confirmatory trial was conducted to test this hypothesis.Methods: This 16-week, multicenter, double-blind, randomized, placebo-controlled study included 200 subjects meeting DSM-IV-TR criteria for schizophrenia or schizoaffective disorder. Patients were randomized to receive either pramipexole (0.75 mg twice daily, n = 100) or placebo (n = 100) as an add-on to their regular antipsychotic treatment. The primary outcome measure was the total score on the Positive and Negative Syndrome Scale (PANSS); secondary outcome measures included PANSS subscale and cognitive functioning scores. Recruitment was performed in 30 sites in Romania and 1 site in the Republic of Moldova between January and June 2011.Results: Analysis of covariance models showed no significant difference between pramipexole and placebo for total PANSS (P > .99) and PANSS positive (P > .99), negative (P = .73), and general psychopathology (P = .99) subscale scores. Changes in Clinical Global Impressions-Severity of Illness scale and Brief Assessment of Cognition in Schizophrenia scores showed no significant difference between pramipexole and placebo.Conclusions: The results of this large randomized controlled trial indicated that pramipexole was not efficacious as an add-on to antipsychotic medications for schizophrenia.Trial Registration: ClinicalTrials.gov identifier NCT01320982.

RESUMO

Schizophrenia is a complex and incompletely elucidated pathology that affects sensorimotor function and also produces numerous therapeutic challenges. The aims of this cross-sectional study were to identify the profile of neurological soft signs (NSS) in patients with predominantly negative symptoms of schizophrenia (PNS) compared with patients with schizophrenia who do not present a predominance of negative symptoms (NPNS) and also to objectify the impact of treatment on the neurological function of these patients. Ninety-nine (n = 99; 56 females and 43 males) patients diagnosed with schizophrenia according to DSM-V were included; these patients were undergoing antipsychotic (4 typical antipsychotics, 86 atypical antipsychotics, and 9 combinations of two atypical antipsychotics) or anticholinergic treatment (24 out of 99) at the time of evaluation, and the PANSS was used to identify the patients with predominantly negative symptoms (n = 39), the Neurological Evaluation Scale (NES) was used for the evaluation of neurological soft signs (NSS), and the SAS was used for the objectification of the extrapyramidal side effects induced by the neuroleptic treatment, which was converted to chlorpromazine equivalents (CPZE). The study's main finding was that, although the daily dose of CPZE did not represent a statistically significant variable, in terms of neurological soft signs, patients with PNS had higher rates of NSS.

RESUMO

BACKGROUND: Weather a psychological construct or a clinical entity, numerous studies have been focused on the biological link between stress, burnout, and biomarkers. AIM: The purpose of our study was to search the existing literature and summarize the immunological and endocrine alterations found in burnout patients and, also, to provide updated data for clinicians to use. METHODS: We performed a literature search in PubMed database using specific terms. RESULTS: The primary focus of the literature seems to be the hypothalamic-pituitary-adrenal (HPA) axis, which may be affected due to chronic stress, which can be investigated by measuring hormonal responsiveness [corticotropin-releasing hormone (CRH), adrenocorticotropic hormone (ACTH), cortisol, prolactin, thyroid hormones]. An important challenge that this field is faced with is the pulsatile and diurnal fluctuation of them, which may not always be considered and the heterogeneity of burnout measurements. Many studies have explored the linking pathways between the immune system and chronic stress, but only a few have specifically evaluated this process for future diagnostic or prognostic biomarkers. CONCLUSIONS: Burnout has cumulative effects on our body and stress does not affect us in a singular direction, on the contrary, significant clinical implications are found, not only microscopic, but affective symptoms leading to anxiety and depression.

RESUMO

This study aimed to measure the scores of well-being, subjective happiness, sense of meaning, and coping in Romanian physicians and the potential impact on them of systematically attending Balint groups. Eighty participants (33 men, 47 women, mean age 38.90, SD 9.73) were included in the study. From them, 43 had systematically attended a Balint group in the last two years, while the others represented the controls. All participants were administered the Meaning of Life Questionnaire, the Job-related Affective Well-being Scale, the Brief COPE Scale, and the Subjective Happiness Scale. t-tests and MANOVA were used to compare the group scores and the impact of Balint training on the study variables. Results showed that Balintian participants had a lower use of denial and self-blame and were more oriented towards the seeking of emotional and instrumental support. They also reported higher scores in high pleasurable-low arousal emotions, positive emotions, and in the perception of the presence of meaning. Still, when considering other additional predictors (gender, age), the distinct impact of Balint training remained limited to the preference for certain coping mechanisms. These results could stimulate the use of Balint groups as a tool for the physician's formation programs.

RESUMO

The co-occurrence of epilepsy and psychiatric disorders is long known. The scope of this systematic review was to describe the prevalence of specific interictal psychiatric disorders in patients with epilepsy and to assess possible associations between psychiatric disorders and other sociodemographic or clinical characteristics of epilepsy patients. MEDLINE and ScienceDirect were searched for original articles published between January 2015 and February 2021 describing studies that involved epilepsy patients with psychiatric comorbidities. We identified 13 studies with heterogenous methodology and reporting. Prevalence of any psychiatric disorder observed was up to 51% in idiopathic generalized epilepsy (IGE), up to 43.1% in temporal lobe epilepsy (TLE) and up to 43.3% in a general population of patients with epilepsy. The most frequent psychiatric comorbidities associated with epilepsy included mood/affective disorders (up to 40% for lifetime occurrence and up to 23% for current occurrence), anxiety disorders (up to 30.8% for lifetime occurrence and up to 15.6% for current occurrence), personality disorders [up to 11% in juvenile myoclonic epilepsy (JME)] and psychotic disorders (up to 4% of epilepsy patients). In focal epilepsy, depressive disorders might be associated with specific brain imaging findings and with cognitive impairment. Anxiety disorders are associated with a higher frequency of generalized tonico-clonic seizure (GTCS) and with worse social functioning. Psychotic disorders were found to be associated with longer duration of epilepsy. Childhood maltreatment experiences were found to be a powerful predictor for the occurrence of psychiatric comorbidities in epilepsy patients, while data regarding association of other epilepsy characteristics with the presence of psychiatric disorders is conflicting.
