Quantitative EEG in the Differential Diagnosis of Dementia Subtypes.

OBJECTIVE: Most neurodegenerative dementias present with substantial overlap in clinical features. Therefore, differential diagnosis is often a challenging task necessitating costly and sometimes invasive diagnostic procedures. A promising, non-invasive and cost-effective method is the widely available electroencephalography (EEG). METHODS: Twenty-three subjects with Alzheimer's disease (AD), 28 subjects with dementia with Lewy bodies (DLB), 15 subjects with frontotemporal dementias (FTDs), and 22 healthy controls (HC) were enrolled. Nineteen channel computerized EEG recordings were acquired. Mean relative powers were calculated using the standard frequency bands. Theta/alpha ratio (TAR), theta/beta ratio (TBR), a spectral index of (alpha + beta)/(theta + delta) and an alpha reactivity index (alpha in eyes-open condition/alpha in eyes-closed condition) were also calculated. Receiver operating characteristic (ROC) analyses were performed to assess diagnostic accuracy. RESULTS: For the comparison of EEG measures across groups, we performed a multivariate ANOVA followed by univariate ANOVAs controlling for the effects of age, with post hoc tests. Theta power and TBR were increased in DLB compared to other groups. Alpha power was decreased in DLB compared to HC and FTD; and in AD compared to FTD. Beta power was decreased in DLB compared to AD and HC. Furthermore, regional analyses demonstrated a unique pattern of theta power increase in DLB; affecting frontal, central, parietal, occipital, and temporal regions. In AD, theta power increased compared to HC in parietal, occipital, and right temporal regions. TAR was increased in DLB compared to other groups; and in AD compared to HC. Finally, alpha reactivity index was higher in DLB compared to HC and FTD. In AD, EEG slowing was associated with cognitive impairment, while in DLB, this was associated with higher DLB characteristics. In the ROC analyses to distinguish DLB from FTD and AD, measures of EEG slowing yielded high area under curve values, with good specificities. Also, decreased alpha reactivity could distinguish DLB from FTD with good specificity. EEG slowing in DLB showed a diffuse pattern compared to AD, where a posterior and temporal slowing predominated. CONCLUSION: We showed that EEG slowing was satisfactory in distinguishing DLB patients from AD and FTD patients. Notably, this slowing was a characteristic finding in DLB patients, even at early stages, while it paralleled disease progression in AD. Furthermore, EEG slowing in DLB showed a diffuse pattern compared to AD, where a posterior and temporal slowing predominated. These findings align with the previous evidence of the diencephalic dysfunction in DLB.

A comparative transcranial magnetic stimulation study: Assessing cortical excitability and plasticity in Alzheimer's disease, dementia with Lewy bodies and Frontotemporal dementia.

BACKGROUND: Here, we aimed to investigate the roles of long-term potentiation-like (LTP-like) plasticity using intermittent theta burst (iTBS) protocol and resting motor threshold (rMT) in the differential diagnosis of Alzheimer's disease (AD), diffuse dementia with Lewy bodies (DLB) and frontotemporal dementia (FTD). METHOD: We enrolled 21 subjects with AD, 28 subjects with DLB, 14 subjects with FTD, and 33 elderly subjects with normal cognitive functions into the study. We recorded rMT and percentage amplitude change of motor evoked potentials (MEPs) after the iTBS protocol in each group. RESULTS: In patients with AD and DLB, the percentage amplitude change of MEPs, and rMTs were significantly lower than in healthy subjects. However, no significant difference was observed in individuals with FTD. CONCLUSION: Our findings showed that transcranial magnetic stimulation measures, particularly rMTs and LTP-like plasticity, may be potential biomarkers to distinguish between different dementia subtypes. Impaired motor cortical excitability and synaptic plasticity were more prominent in AD and DLB than in FTD. This aligns with the evidence that cortical motor networks are usually spared in FTDs in early-to-middle stages.

The Impact of Coping Strategies on Suicide Attempts and Suicidal Ideation in Bipolar Disorder.

ABSTRACT: The stress coping strategies of patients with bipolar disorder (BD) may affect their suicide risk. We examined coping behaviors and impact of coping strategies and clinical characteristics on suicide attempts and lifetime suicidal ideation in patients with BD I, compared with a healthy control group. We recruited 185 euthymic patients with BD and 94 healthy controls. Participants completed the Coping Orientation to Problems Experienced Inventory. Suicide attempt prevalence in patients with BD was around 34%, and frequency of lifetime suicide ideation was around 60%. Binary logistic regression analysis revealed greater use of behavioral disengagement and religious coping strategies among patients with BD, compared with controls. Patients with previous suicide attempts presented a more severe illness course, notably early onset, with more depressive and mixed episodes and a more dysfunctional coping style than nonsuicidal patients. Behavioral interventions can target avoidant coping behavior, such as denial, especially in patients with suicide attempts.

Toxoplasma gondii infection by serological and molecular methods in schizophrenia patients with and without suicide attempts: An age-sex-matched case-control study.

INTRODUCTION: The opinion that latent Toxoplasma gondii infection is having a broadly asymptomatic projection has now been interrogated, in specific due to the echoed association between the latent infection and an elevated incidence of schizophrenia or even suicide attempts. Notwithstanding conducted studies aimed to understand this feasible link are restricted. METHODS: In the present case-control study, we focused to illuminate the relationship between the serological and molecular presence of T gondii and schizophrenia with or without the suicide attempts by comparing it with healthy individuals. A total of 237 participants (117 in schizophrenia and 120 in healthy control) were included in this study. RESULTS: Overall, latent T gondii infections were found statistically higher in 63 (53.8%) of the 117 patients with schizophrenia and in 33 (27.5%) of the 120 controls (P < .001). In schizophrenia patients, seroprevalence T gondii was again found to be statistically higher in suicide attempters (59.6%), compared with no history of suicide attempts (48.3%; P < .05). The molecular positivity rate of T gondii DNA was higher in the schizophrenia group, compared with the healthy control group (P < .05), whereas the history of suicide attempts was not statistically associated (P = .831) with T gondii DNA positivity by polymerase chain reaction. CONCLUSION: This case-control study enlightens additional demonstration to the belief that T gondii infection would be an underlying component for the pathophysiology of schizophrenia. Regardless of the clarity results of this study, this supposition warrants further endorsement.

Evaluation of the Effectiveness of Psychoeducation Given to Children with Parental Psychiatric Disorders.

This study was aimed to determine the effectiveness of psychoeducation program which was developed to improve the coping skills and to increase the psychological resistance of 12-18 years children/adolescents whose parents' have psychiatric disorders. The study was carried out between May 2018 - November 2019 with children of patients who applied to the outpatient clinic and inpatient treatment at Istanbul University - Cerrahpasa, Cerrahpasa Faculty of Medicine Department of Psychiatry. Total of 40 children (experiment = 20 and control = 20), participated in the study. Data were collected using Personal Information Form, Adolescent Psychological Resilience Scale and Kidcope. The mean age of the children/adolescents in the experimental group was 14.05 ± 1.90, 50% was male and the mean age of the control group was 15.35 ± 2.08, and 55% were male. It was determined that the mean duration of psychiatric disorders were 11.50 ± 6.39 years and 40% of the psychiatric diagnosis was schizophrenia in the experimental group, and the mean duration psychiatric disorders were 6.10 ± 5.16 years and 30% of the psychiatric diagnosis was a depression in the control group. After psychoeducation, the total scores of scales in the experimental group showed an increase compared to the control group and a significant difference in a statistical context. It was found that children/adolescents participating in the psychoeducation program had increased psychological resilience levels and improved coping skills. This result shows that the psychoeducation program for children/adolescents with psychiatric disorders in their parents is effective.

ECT augmentation of antipsychotics in severely ill schizophrenia: a naturalistic, observational study.

OBJECTIVES: There is positive evidence to support the role of electroconvulsive therapy (ECT) in the treatment of schizophrenia; however, it is unclear to what extent this growing evidence reflects the actual situation in clinical practice. The aim of this study was to explore the efficacy of ECT augmentation to antipsychotics in individuals with schizophrenia in a naturalistic-observational environment. METHODS: Eighty-one patients diagnosed with schizophrenia, hospitalised due to acute psychotic exacerbation were included in the study. We compared changes in Positive and Negative Symptom Rating Scale (PANSS) scores between patients treated only with APs and those in the ECT augmentation group. RESULTS: A statistically significant decrease in symptom severity was observed in all PANSS subscales in both groups. In the ECT group, 95% of the patients (n = 39) responded to treatment compared to 75% of the non-ECT group (n = 30) (χ2=6.496, df = 1, p = 0.011). We found that combining ECT with AP significantly increased treatment response, which was defined as at least 25% PANSS symptom reduction, in patients with acute exacerbation of schizophrenia, compared to AP alone. CONCLUSIONS: Augmentation of ECT seems to increase responsiveness during acute treatment of severely ill schizophrenia patients. The mean percentage reduction in PANSS scores by 25% following antipsychotic treatment can help identify patients that will benefit from ECT after psychotic relapse in future. Key points There is positive evidence to support the role of ECT in the treatment of schizophrenia; however, it remains unclear to what extent this growing evidence reflects the actual situation in clinical practice. Augmentation of ECT seems to increase responsiveness during acute treatment of severely ill schizophrenia patients. The addition of ECT to antipsychotic treatment may only be beneficial in patients with antipsychotic responses below 50%. The mean percentage reduction in PANSS scores by 25% following antipsychotic treatment can help identify patients that will benefit from ECT after psychotic relapses in the future.

Successful use of electroconvulsive therapy in a patient with anorexia nervosa and severe acute-onset obsessive-compulsive disorder.

Anorexia nervosa (AN) is a complex condition that is often accompanied by several serious comorbidities that may require a variety of treatment modalities throughout the course of the illness. Obsessive-compulsive disorder (OCD), which is common in patients with AN, may occasionally cause serious interruptions to the daily functioning of the patient. We report on a 24-year-old male patient with chronic AN. During the beginning of his illness, he had a major depressive episode that was followed by AN onset. Throughout his illness, he also experienced chronic moderate depressive symptoms and later developed severe OCD. He experienced complete remission from the OCD and an improved mood after undergoing a course of bilateral electroconvulsive therapy (ECT). His OCD symptoms did not recur during the first year of follow-up. ECT may prove to be a fast and effective treatment strategy for severe and disabling acute-onset OCD that occurs during the course of comorbid AN. The case described herein shows how a comorbid psychiatric disorder in a patient suffering from chronic AN may disrupt the daily functioning of the patient if it is not urgently treated.

Alterations in Body Uneasiness, Eating Attitudes, and Psychopathology Before and After Cross-Sex Hormonal Treatment in Patients with Female-to-Male Gender Dysphoria.

Body dissatisfaction plays an important role in the development of psychiatric problems such as eating disorders as well as gender dysphoria (GD). Cross-sex hormonal treatment (CHT) alleviates the dissatisfaction by making various changes in the body. We examined the alteration of body uneasiness, eating attitudes and behaviors, and psychological symptoms longitudinally in Turkish participants with female-to-male gender dysphoria (FtM GD) after CHT. Thirty-seven participants with FtM GD and 40 female controls were asked to complete the Body Uneasiness Test to explore different areas of body-related psychopathology, the Eating Attitudes Test to assess eating disturbances, and the Symptom Checklist-90 Revised to measure psychological state, both before CHT and after 6 months of CHT administration. The baseline mean body weight, BMI scores, body uneasiness scores, and general psychopathological symptoms of participants with FtM GD were significantly higher than female controls, whereas baseline eating attitudes and behaviors were not significantly different. Over time, FtM GD participants' mean body weight and BMI scores increased, body uneasiness and general psychopathological symptoms decreased, and eating attitudes and behaviors had not changed at 24th weeks following CHT administration compared to baseline. CHT may have a positive impact on body uneasiness and general psychopathological symptoms in participants with FtM GD. However, CHT does not have an impact on eating attitudes and behaviors.

Dissociative depression among women with fibromyalgia or rheumatoid arthritis.

The aim of this study was to inquire about the possible relations of childhood trauma, anger, and dissociation to depression among women with fibromyalgia or rheumatoid arthritis. Fifty female patients diagnosed as having fibromyalgia (n = 30) or rheumatoid arthritis (n = 20) participated in the study. The Childhood Trauma Questionnaire, Somatoform Dissociation Questionnaire (SDQ), Dissociation Questionnaire (DIS-Q), Beck Depression Inventory (BDI), Spielberger State-Trait Anger Expression Inventory, and Dissociative Disorders Interview Schedule were administered to all participants. Women with a lifetime diagnosis of depressive disorder had higher scores for somatoform and psychoform dissociation than the nondepressive patients. However, childhood trauma scores did not differ between the 2 groups. In regression analysis, current severity of depression (BDI) was predicted by psychoform dissociation (DIS-Q) and lower education, and lifetime diagnosis of major depression was predicted by somatoform dissociation (SDQ). Whereas childhood emotional neglect predicted somatoform dissociation, psychoform dissociation was predicted by childhood sexual abuse. Mental processing of anger seems to be 1 of the dimensions of psychodynamics in trauma-related depressive conditions. In the context of the perceived threat of loss of control due to expressed anger and mental disintegration, somatoform dissociation seems to contribute to overmodulation of emotions in dissociative depression. Among patients suffering from physical illness with possible psychosomatic dimensions, assessment of somatoform dissociation in addition to psychoform dissociation may be helpful to understand diverse psychopathological trajectories emerging in the aftermath of childhood adversities. The recently proposed category of "dissociative depression" (Sar, 2011) seems to be a promising concept for future research on psychosomatic aspects of traumatic stress.

Effects of electroconvulsive therapy on plasma levels of neuroactive steroids in inpatients with major depression.

OBJECTIVE: Neuroactive steroids (NAS) are neuroactive molecules that have been shown to be associated with various psychiatric disorders. There are some inconclusive findings about the alteration in neuroactive steroid levels after the treatment of depression and ECT is still one of the most effective treatment choices for treatment resistant depression. Thus, we aimed to investigate the alterations of several NAS in plasma after ECT in inpatients with treatment resistant depression. METHODS: In this study we enrolled 19 consecutive patients, 12 female and 7 male inpatients with major depression, who were not responding to medication, for whom ECT was Indicated, and were not taking any antidepressant treatment for at least a week prior to enrolment. We measured plasma progesterone, testosterone, pregnenolone, dehydroepiandrosterone (DHEA), dehydroepiandrosterone sulfate, and estradiol levels before and after ECT. RESULTS: The mean age of the participants was 38.3 ± 9.4 years. The mean plasma neuroactive steroid levels were insignificant between baseline and post ECT in patients with treatment resistant depression. CONCLUSIONS: ECT does not seem to influence plasma neuroactive steroid levels in patients with treatment resistant depression. Additionally, plasma dehydroepiandrosterone and pregnenolone levels might be associated with improvement in depressive symptoms after ECT.

Psychosocial Impairment in Older Patients With Bipolar I Disorder.

BACKGROUND: The goal of this study was to assess psychosocial functioning in older patients with bipolar I disorder compared with healthy subjects and to identify the psychopathological factors associated with poor functioning in patients. METHODS: We recruited 68 euthymic patients with bipolar I disorder from the outpatient unit and 89 healthy controls who were older than 50 years of age. In addition to clinical variables, we used other standardized measures, including the Young Mania Rating Scale, the Hamilton Depression Rating Scale, the Hamilton Anxiety Rating Scale, the Functional Assessment Short Test, and the Montreal Cognitive Assessment. RESULTS: Older patients with bipolar I disorder had poorer psychosocial functioning in general and in the domains of occupation, autonomy, and cognition than the healthy controls on the basis of previously defined Functional Assessment Short Test cutoff scores. We found that 35.3% (95% CI: 23%-47%) of the patients did not have clinically significant functional impairment, 38.2% (95% CI: 26%-50%) had mild impairment, and 26.5% (95% CI: 16%-37%) had moderate impairment. Depressive symptoms and impaired cognition were associated with poor overall functioning. CONCLUSIONS: The level of psychosocial functioning was heterogeneous among the patients. Subsyndromal depressive symptoms, even at low levels, and impaired cognition predicted poor functioning in euthymic middle-aged and older patients with bipolar I disorder.

Plasma Biomarkers in Neurodegenerative Dementias: Unrevealing the Potential of Serum Oxytocin, BDNF, NPTX1, TREM2, TNF-alpha, IL-1, and Prolactin.

BACKGROUND: Dementia encompasses a range of neurodegenerative disorders characterized by cognitive decline and functional impairment. The identification of reliable biomarkers is essential for accurate diagnosis and gaining insights into the mechanisms underlying diseases. OBJECTIVE: This study aimed to investigate the plasma biomarker profiles associated with Brain- Derived Neurotrophic Factor (BDNF), Oxytocin, Neuronal Pentraxin-1 (NPTX1), Triggering Receptor Expressed on Myeloid Cells 2 (TREM2), Tumor Necrosis Factor-alpha (TNF-alpha), Interleukin- 1 (IL-1), and Prolactin in Alzheimer's disease (AD), dementia with Lewy bodies (DLB), frontotemporal dementias (FTD), and healthy controls. METHODS: Serum levels of the aforementioned biomarkers were analyzed in 23 AD, 28 DLB, 15 FTD patients recruited from outpatient units, and 22 healthy controls. Diagnostic evaluations followed established criteria, and standardized clinical tests were conducted. Blood samples were collected and analyzed using ELISA and electrochemiluminescence immunoassay methods. RESULTS: Serum BDNF and oxytocin levels did not significantly differ across groups. NPTX1, TREM2, TNF-alpha, and IL-1 levels also did not show significant differences among dementia groups. However, prolactin levels exhibited distinct patterns, with lower levels in male DLB patients and higher levels in female AD patients compared to controls. CONCLUSION: The study findings suggest potential shared mechanisms in dementia pathophysiology and highlight the importance of exploring neuroendocrine responses, particularly in AD and DLB. However, further research is warranted to elucidate the role of these biomarkers in dementia diagnosis and disease progression.

The impact of COVID-19 pandemic and lockdown on emergency psychiatry department admissions.

This study aimed to explore the impact of the coronavirus disease 2019 pandemic and lockdown period measures on patients' visits to the psychiatric emergency department (PED) of a University Hospital in Istanbul. We compared the number and characteristics of patients during the initial lockdown with visits in the pre- and post-lockdown months. We also investigated the number of monthly PED visits and hospitalizations between March 11, 2020 and 2021 and compared it to the same period in 2019 and between March 2021 and 2022. PED visits in the initial lockdown period in our university increased by 109% compared to the prelockdown months in the previous year. Anxiety and depressive disorders were responsible for most of this increase. The decline in PED visits was 3.1% and 42% during the first and second year of the pandemic, respectively; however, among the major diagnostic categories, we found that the rates of anxiety, depressive disorders, and obsessive-compulsive disorder increased significantly in the first year, while psychotic disorders declined and bipolar disorders remained the same. In the second year, there was a trend toward prepandemic year ratios. These findings show that the pandemic affects PED admissions in different ways at different periods. These data may also help shaping the public policies necessary to meet the evolving needs in the field of mental health of society at different public crises in the future.

Suicidal ideation, post-traumatic stress disorder, and depression in traumatic spinal cord injury: What resilience tells us.

OBJECTIVE: Identification of unmet psychiatric needs, protective and risk factors for suicide are crucial for people with traumatic spinal cord injury (SCI). In this study, we aimed to explore depression, post-traumatic stress disorder (PTSD) status (non-PTSD, partial-PTSD, full-PTSD), resilience, suicidal ideation (SI) and to examine predictors and clinical correlates of current SI in traumatic SCI. METHOD: Sixty-three individuals with traumatic SCI who were at least 3 months post-injury were included in the study. The participants were evaluated in terms of PTSD Checklist for Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (PCL-5), depression, SI, and resilience using the PCL-5, the Patient Health Questionnaire-9, the Brief Resilience Scale, and sociodemographic measures. RESULTS: 33% of our sample (n = 21) had SI over the past two weeks. 71.4% of the patients with SI (n = 15) had depression. A total of 52.4% of the patients with SI (n = 11) were diagnosed with full PTSD. Resilience was found to be significantly lower in individuals with depression and individuals with SI. While depression predicted SI in traumatic SCI, resilience stands as a protective factor against SI. CONCLUSION: SI is quite common in individuals with traumatic SCI and is accompanied by substantial psychiatric comorbidities such as depression and PTSD. Along with depression and PTSD, resilience - which has protective and predictive values and is inversely associated with SI - constitutes a significant psychotherapeutic intervention and screening area.

Are bipolar disorder, major depression, and suicidality linked with Toxoplasma gondii? A seromolecular case-control study.

OBJECTIVE: The existence of predisposing effects of latent Toxoplasma gondii (T. gondii) infection in bipolar disorder (BD), major depression (MD), and even suicide attempt (SA) has long been debatable. This conjecture remains unclear because there is a lack of evidence regarding how T. gondii manipulates the brain and behavior. METHODS: We investigated the influence of T. gondii infection on BD and MD patients with or without SA compared to age-, sex-, and province-matched healthy controls (HCs) concurrently with serology and molecular-based evaluations. We prospectively assessed 147 volunteers with BD, 161 with MD, and 310 HCs. RESULTS: T. gondii seropositivity rates were 57.1% for BD, 29.2% for MD, 64.8% for SA, and 21.3% for HC. Binary logistic regression analyses revealed that T. gondii positive Immunoglobulin G (IgG) status may be a prominent tendentious agent for BD (OR = 3.52; 95% CI [2.19-5.80]; p < 0.001) and SA (OR = 17.17; 95% CI [8.12-36.28]; p < 0.001), but not for MD (OR = 1.21; 95% CI [0.74-1.99]; p = 0.45). Nevertheless, the T. gondii DNA ratios determined by polymerase chain reaction (PCR) were linked to BD and MD. CONCLUSION: Our findings strongly support the burgeoning interest in the possibility that latent T. gondii infection may be relevant to the etiology of BD and SA, although this connection remains ambiguous.

Treatment adherence and anxiety levels of bronchiectasis patients in the COVID-19 pandemic.

It has been reported that during the coronavirus disease-2019 (COVID-19) pandemic, bronchiectasis patients were adversely affected due to their limited respiratory functions and acute exacerbations which were triggered by viral infections. The increased concern in the population during the pandemic has affected the attitudes of people toward avoiding disease and patients' treatment compliance. It is unclear whether treatment adherence and anxiety levels of bronchiectasis patients have changed during the pandemic. We aimed to evaluate treatment adherence and anxiety levels in patients with bronchiectasis. A cross-sectional survey was conducted between May and November 2021. A total of 123 patients with bronchiectasis and 110 adults without chronic diseases were included in the control group. Patient demographic information, bronchiectasis follow-up data, and COVID-19 history were recorded. Then, patients filled out "MARS-5 Index" (Medical Adherence Report Scale-5), Beck Anxiety Scale and the Effect of Events Scale (IES-R). Responses of questionnaires were statistically analyzed. Our results showed that the majority of patients with bronchiectasis had high Medical Adherence Report Scale-5 index total scores during the COVID-19 pandemic (86.2%). The total scores on the Beck Anxiety Scale of bronchiectasis patients who did not have COVID-19 were significantly higher than those who had COVID-19 (P = .04). The total scores on the IES-R were found to be significantly higher in the control group (P < .001). No significant difference was found in the total scores on the Beck Anxiety Scale between the patients and the control group. The bronchiectasis patients had high adherence to their current treatment during the COVID-19 period and were less affected by the pandemic and its psychological effects compared to the healthy population. Furthermore, individuals diagnosed with bronchiectasis who were not infected with COVID-19 demonstrated increased levels of anxiety compared to those who were infected with COVID-19 which may be due to their concern about contracting the disease.

Co-existing bipolar disease and 17q12 deletion: a rare case report.

BACKGROUND: 17q12 microdeletion syndrome is a rare autosomal dominant chromosomal anomaly, caused by the deletion of a 1.4 Mb-spanning DNA sequence on the long arm of chromosome 17. Herein, we report the first bipolar disease (BPD) case with a 1.6-Mb deletion in the 17q11.2-17q12 chromosome region. MATERIALS AND METHODS: Physical examination of the case was performed. Karyotype and microarray analyses were performed for the case and the parents. RESULTS: Physical examination revealed mild dysmorphic features such as high and forehead, full cheeks, slightly depressed nasal bridge and arched eyebrow. Chromosomal analysis of the patient revealed 46, XX, del(17)(q12) karyotype, and parents' karyotype were normal. In the microarray analysis of patient, 1.6 megabases deletion was detected in the 17q12 region [arr(hg19) 17q12 (34,611,352-36,248,918) ×1]. The microarray analysis of the mother was normal. The father's microarray showed 473 kilobases duplication in the 11p11.12 region. CONCLUSION: Although 17q12 deletion syndrome has been associated with bipolar disorder, very few such cases have been described in the literature. Genetic counseling should be considered in patients with remarkable phenotype, complex symptomatology, neurodevelopmental disorder and additional conspicuous medical conditions.

Minor physical anomalies and neurological soft signs in patients with schizophrenia and their siblings.

Neurological soft signs (NSSs) and minor physical anomalies (MPAs) are consistently found at higher rates in individuals with schizophrenia compared to healthy controls. However, limited research has been conducted on these traits among the biological relatives of these patients. We aimed to identify the possible origins of these traits in schizophrenia by exploring them in patients with schizophrenia, their healthy siblings and normal controls. Ninety-six patients with schizophrenia, their 66 non-psychotic siblings and 52 healthy subjects were studied. Measures included the Neurological Evaluation Scale, a structured examination for detection of minor physical anomalies, stroop and verbal fluency tests for cognitive assessment, and scales for assessment of disease severity in patients; the Scale for the Assesment of Negative Symptoms and the Scale for the Assesment of Positive Symptoms. Increased rates of NSSs and high MPA scores were found in both the patients and their siblings as compared to normal controls. MPAs in several body regions were similar (eyes, ears, hands and feet) or correlated (innercanthal width and head circumference) between patients and their respective siblings. However, there was little similarity in palate and tongue anomalies between these subjects. These results suggest that NSSs and MPAs might represent two distinct markers of risk for schizophrenia. MPAs at different locations may also represent distinct pathological processes, such that palate and tongue abnormalities are more likely to represent non-familial rather than familial factors compared to other abnormalities.

A Multi-Dimensional Psychiatric Perspective on the Impact of the COVID-19 Pandemic.

Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) arose in Wuhan, China in December 2019 and spread worldwide rapidly, and was declared a global pandemic by the World Health Organization as of March 2020. As the SARS-CoV-2 pandemic has spread worldwide, its impact is increasingly being recognized among vulnerable groups and also by the public in general. Recent findings indicate that patients with mental health disorders are among the groups most vulnerable to psychological stress and social hardships related to the current pandemic. Studies also indicate an increased risk of infection by SARS-CoV-2 in subjects with psychiatric disorders. Patients affected by SARS-CoV-2 may present to the psychiatrist with delirium, psychotic symptoms, depression, anxiety, post-traumatic stress disorder, and insomnia. Some patients will develop persistent somatic symptoms such as fatigue after the acute infection. In this article, we summarize the preliminary findings related to the effects of the SARS-CoV-2 pandemic on patients with mental health disorders, as well as recent research on psychiatric presentations in patients affected by SARS-CoV-2.
