Four Core Concepts in Psychiatric Diagnosis.

In the present article, we aimed at describing the diagnostic process in Psychiatry through a phenomenological perspective. We have identified 4 core concepts which may represent the joints of a phenomenologically oriented diagnosis. The "tightrope walking" attitude refers to the psychiatrist's ability to swing between 2 different and sometimes contrasting tendencies (e.g., engagement and disengagement). The "holistic experience" includes all those intuitive, nonverbal, and pre-thematic elements that emerge in the early stages of the clinical encounter as an emanation of the atmospheric quality of the intersubjective space. The "co-construction of symptoms" regards the hermeneutic process behind psychiatric symptoms, involving both the patient as a self-interpreting agent and the clinician as a translator of his/her experience. Finally, by the "evolving typification" we mean that the closer the relationship becomes with the patient, the more specific and nuanced becomes the typification behind psychiatric diagnosis. Each of these concepts will be accompanied by an extract from a clinical case deriving from one of the authors' most recent clinical experiences.

Stigma and attitudes towards restrictive practices in psychiatry among psychology students: a network and path analysis study in an Italian sample.

Background: People suffering from mental disorders are affected by public stigma in many areas of daily life, including mental health services. Stigma among mental health professionals needs to be addressed.Aims: This study explores the path leading to attitudes toward seclusion and restraint practices among future mental health professionals, considering the complex interplay among demographic variables, personality, stigma, and experience in psychiatric services.Method: Network analysis and Structural Equation Modeling were used to explore 1512 Psychology students. The survey instrument included a form for demographic and academic variables, the Attribution Questionnaire-9, the Ten Items Personality Inventory, and few questions exploring attitudes toward open-door and restraint-free policies in Psychiatry.Results: The personality trait of Openness and previous experience with psychiatric patients resulted to play a positive effect on stigma. Openness was also associated with a better disposition towards restraint-free policies. Conversely, higher levels of stigma predicted a negative attitude toward no restraint, decreasing the positive effect of Openness.Conclusions: In conclusion, some personality traits may be associated with lower levels of stigma and a more open view about treatment policies in Psychiatry. Direct educational or professional experience with patients suffering from mental disorders may be a crucial factor in reducing the risk of stigmatizing attitudes in future professionals.

A Mixed Program of Psychoeducational and Psychological Rehabilitation for Patients With Bipolar Disorder in a Day Hospital Setting.

The present study describes a new mixed program of psychoeducational and psychological interventions for bipolar patients, applicable during everyday practice. Thirty-two bipolar patients recruited at a psychiatric day-hospital service have been admitted to a program consisting of 30 meetings and 2 follow-ups at 6 and 12 months. The psychoeducational support determined a general improvement of all included patients. At baseline, patients with residual depression had higher Hamilton Depression Rating Scale (HDRS) scores than euthymic patients (mean score ± SD: 21.25 ± 3.92 vs. 7.00 ± 2.95, respectively). After psychoeducation sessions, the HDRS scores of euthymic patients remained stable (mean ± SD: 7.00 ± 3.74), whereas the HDRS scores of depressed patients demonstrated a statistically significant improvement (mean ± SD: 14.00 ± 6.72, t = 2.721, p = 0.03). Results of the Connor-Davidson Resilience scale and specifically constructed questionnaire Questionario per la Valutazione della Conoscenza e dell'Apprendimento per il Disturbo Bipolare showed a statistically significant improvement in resilience and insight in all recruited patients. Psychoeducational intervention as adjunctive treatment to pharmacotherapy seems to be very effective in bipolar patients, not only for those in the euthymic phase, but this model could also be extended to patients with an ongoing mild or moderate depressive episode.

Lamotrigine compared to placebo and other agents with antidepressant activity in patients with unipolar and bipolar depression: a comprehensive meta-analysis of efficacy and safety outcomes in short-term trials.

OBJECTIVES: To meta-analytically summarize lamotrigine's effectiveness and safety in unipolar and bipolar depression. METHODS: We conducted systematic PubMed and SCOPUS reviews (last search =10/01/2015) of randomized controlled trials comparing lamotrigine to placebo or other agents with antidepressant activity in unipolar or bipolar depression. We performed a random-effects meta-analysis of depression ratings, response, remission, and adverse effects calculating standardized mean difference (SMD) and risk ratio (RR) ±95% confidence intervals (CIs). RESULTS: Eighteen studies (n=2152, duration=9.83 weeks) in patients with unipolar depression (studies=4, n=187; monotherapy vs lithium=1, augmentation of antidepressants vs placebo=3) or bipolar depression (studies=14, n=1965; monotherapy vs placebo=5, monotherapy vs lithium or olanzapine+fluoxetine=2, augmentation of antidepressants vs placebo=1, augmentation of mood stabilizers vs placebo=3, augmentation of mood stabilizers vs trancylpromine, citalopram, or inositol=3) were meta-analyzed. Lamotrigine's efficacy for depressive symptoms did not differ significantly in monotherapy vs augmentation studies (vs. placebo: p=0.98, I2=0%; vs active agents: p=0.48, I2=0%) or in unipolar vs bipolar patients (vs placebo: p=0.60, I2=0%), allowing pooling of each placebo-controlled and active-controlled trials. Lamotrigine outperformed placebo regarding depressive symptoms (studies=11, n=713 vs n=696; SMD=-0.15, 95% CI=-0.27, -0.02, p=0.02, heterogeneity: p=0.24) and response (after removing one extreme outlier; RR=1.42, 95% CI=1.13-1.78; p=0.003, heterogeneity: p=0.08). Conversely, lamotrigine did not differ regarding efficacy on depressive symptoms, response, or remission from lithium, olanzapine+fluoxetine, citalopram, or inositol (studies=6, n=306 vs n=318, p-values=0.85-0.92). Adverse effects and all-cause/specific-cause discontinuation were similar across all comparisons. CONCLUSIONS: Lamotrigine was superior to placebo in improving unipolar and bipolar depressive symptoms, without causing more frequent adverse effects/discontinuations. Lamotrigine did not differ from lithium, olanzapine+fluoxetine, citalopram, or inositol.

Clinical correlates of difficult-to-treat depression: Exploring an integrated day-care model of treatment.

BACKGROUND AND AIMS: This study aimed to test the effectiveness of an individualized, integrated, day-care treatment programme for the acute phase of "difficult-to-treat depression" (DTD) in a sample of bipolar and unipolar subjects with a complex co-morbidity pattern. METHODS: A total of 291 patients meeting criteria for DTD were consecutively recruited. All participants underwent a 12-week day-care intervention including individual psychological support and group psycho-education. Subjects were assessed for depressive symptom severity by the 21-item Hamilton Depression Rating Scale (HDRS) at the baseline (T0) and after 4 (T1) and 12 (T2) weeks of treatment. A repeated measures general linear model was performed to test for interactive effects among variables. RESULTS: An overall significant improvement was detected in the majority of cases (F = 138.6, p < 0.0001). Responders reported lower rates of personality disorders and higher baseline depressive severity. An interaction between bipolarity and co-morbidity was associated with a poorer outcome (F = 5.9, p = 0.0034). Family involvement was the only significant predictor for symptom improvement (F = 7.9, adjusted p = 0.0025). CONCLUSIONS: Our intervention proved to be effective in the treatment of complex and severe forms of depression. Our results on the role of family support require further investigation to better define suitable targets for tailored therapeutic approaches.

Mixed, melancholic, and anxious features in depression: a cross-sectional study of sociodemographic and clinical correlates.

BACKGROUND: Major depression (MD) is currently viewed as a heterogeneous condition, characterized by different psychopathological dimensions. METHODS: Our sample was composed of 1,289 nonpsychotic bipolar/unipolar depressed patients. Participants were divided into mixed (MXD), melancholic (MEL), and anxious (ANX) depressed, according to a hierarchical functional model. Sociodemographic and clinical variables were compared across depressive subtypes by χ2 test and analysis of variance. The Young Mania Rating Scale (YMRS) and 2 subscales (melancholic [MEL-S] and psychic-somatic anxiety [PSOM-ANX]) from the Hamilton Depression Rating Scale also served as continuous outcome measures. RESULTS: MXD patients more frequently had bipolar I disorder (BD I), younger age of onset, and a higher familial load for mood disorders. MEL and ANX patients were more frequently diagnosed with major depressive disorder and reported a higher suicide risk. YMRS scores in depression was associated with BD I diagnosis (P < .0001) and manic polarity of the last episode (P < .0001), while a depressive polarity of the last episode (P < .0001) was associated with higher MEL-S score. No specific predictor was associated with PSOM-ANX score. CONCLUSIONS: Overall, our findings suggest that mixed depressive features are associated with significant hallmarks of bipolarity, and melancholic features may be influenced by previous depressive polarity. The symptom domain of anxiety appears to have no specific predictor.

Trait-aggressiveness and impulsivity: role of psychological resilience and childhood trauma in a sample of male prisoners.

BACKGROUND: One of the major challenges for research in the field of human aggression is the need to define the role of personality and trait-like dimensions, such as impulsivity and aggressiveness, in predisposing to violent behavior. AIMS: 1) To determine whether trait- aggressiveness and impulsivity may be associated with socio-demographic, clinical and crime history variables in a sample of male prisoners; 2) to detect any association of those traits with measures of early traumatic experiences and current resilience traits. METHODS: A sample of male prisoners (n = 1356) underwent the Brown-Goodwin Assessment for Lifetime History of Aggression (BGLHA) and the Barratt Impulsivity Scale (BIS). Axis I psychiatric disorders were also assessed. Early traumatic experiences and psychological resilience were detected respectively by the Childhood Trauma Questionnaire (CTQ) and the Connor-Davidson Resilience Scale (CD-RISC). Two non-linear logistic regression models were performed to test for the best predictors of trait-aggressiveness and impulsivity. RESULTS: Subjects with a history of substance use disorders and self-mutilation reported both higher BGLHA and BIS scores. Axis I disorders and suicide attempts were associated with aggressiveness, but not to impulsivity. A consistent correlation was found between BGLHA scores and early traumatic experiences. Resilience was positively correlated to impulsivity but not to aggressiveness scores. CONCLUSIONS: Our results support the view that aggressiveness and impulsivity are two different, albeit related trait-like dimensions of personality, having a different relationship with resilience, and, inferentially, a different impact over the development of psychiatric disorders.

Serious suicidal behaviors: socio-demographic and clinical features in a multinational, multicenter sample.

BACKGROUND: Declared suicidal intent and physical danger are both considered important components in defining suicidal behaviors (SB). AIMS: 1) To investigate characteristics of serious suicidal behaviors (SSB), defined by either suicidal intent or lethality; 2) To determine any difference in terms of socio-demographic, clinical and/or service usage variables between SSB and non-serious suicidal behaviors (NSSB). METHODS: A total of 2631 contacts for SB were registered in the context of the MONSUE (Monitoring Suicidal Behavior in Europe) study project. Demographic and clinical information were registered. ICD-10 was used for classifying data about psychiatric diagnoses, methods used for SB and injuries reported. Clear intentionality, high-case fatality methods and serious injuries all defined SSB (n = 1169; 44.4%) RESULTS: SSB were more often preceded by a contact with an inpatient (either psychiatric or somatic) rather than an outpatient service. Among those having a previous history of SB, SSB subjects had fewer contacts with health services before the previous attempt. The strongest predictors for SSB appeared to be older age and not professing a religion. CONCLUSION: Many of the known factors contributing to the risk of completed suicide were also present for SSB. Our findings on service usage by suicide attempters show which aspects of mental health services should be strengthened in order to improve suicide prevention.

Treatment resistance in severe unipolar depression: no association with psychotic or melancholic features.

BACKGROUND: Depressive subtypes generally have been neglected in research on treatment efficacy. We studied a sample of 699 severe unipolar depressed patients to detect any association between depressive features and treatment resistance. METHODS: Participants were divided into psychotic (PSY, n = 90), melancholic (MEL, n = 430) and non-melancholic (n = 179) subjects according to clinical features. Formal diagnostic criteria (Mini International Neuropsychiatric Interview items), and items from 17-item Hamilton Rating Scale for Depression (HRSD17) were compared across groups. Non-responders were defined by a HRSD17 cut-off score of ≥17 after the last adequate antidepressant treatment. Treatment-resistant depression (TRD) was defined as the failure to respond to ≥2 adequate antidepressant trials. Non-linear regression models were designed to detect associations between depressive subtypes and TRD. RESULTS: PSY and MEL patients appeared to be more severely affected and to share some "core" melancholic symptoms. Both PSY and MEL patients reported a higher rate of seasonality. However, we found no clinical or illness course variable associated with TRD. CONCLUSIONS: Our results indicate that psychotic and melancholic depression share some "core" melancholia symptoms, while no distinguishing psychopathological feature appears to be associated with TRD in severely depressed patients.

Depression across mood disorders: review and analysis in a clinical sample.

OBJECTIVES: In this article we aimed to: (1) review literature concerning the clinical and psychopathologic characteristics of Bipolar (BP) depression; (2) analyze an independent sample of depressed patients to identify any demographic and/or clinical feature that may help in differentiating mood disorder subtypes, with special attention to potential markers of bipolarity. METHODS: A sample of 291 depressed subjects, including BP -I (n = 104), BP -II (n = 64), and unipolar (UP) subjects with (n = 53) and without (n = 70) BP family history (BPFH), was examined to evidence potential differences in clinical presentation and to validate literature-derived markers of bipolarity. Demographic and clinical variables and, also, single items from the Hamilton Depression Rating Scale (HDRS), the Montgomery-Asberg Depression Rating Scale (MADRS), and the Young Mania Rating Scale (YMRS) were compared among groups. RESULTS: UP subjects had an older age at onset of mood symptoms. A higher number of major depressive episodes and a higher incidence of lifetime psychotic features were found in BP subjects. Items expressing depressed mood, depressive anhedonia, pessimistic thoughts, and neurovegetative symptoms of depression scored higher in UP, whereas depersonalization and paranoid symptoms' scores were higher in BP. When compared with UP, BP I had a significantly higher incidence of intradepressive hypomanic symptoms. Bipolar family history was found to be the strongest predictor of bipolarity in depression. CONCLUSIONS: Overall, our findings confirm most of the classical signs of bipolarity in depression and support the view that some features, such as BPFH, together with some specific symptoms may help in detecting depressed subjects at higher risk for BP disorder.

Role of substance abuse comorbidity and personality on the outcome of depression in bipolar disorder: harm avoidance influences medium-term treatment outcome.

Comorbid conditions are frequent in bipolar disorder (BD) and may complicate the treatment and course of illness. We investigated the role of substance use disorder (SUD), axis II personality disorders (PD) and continuous personality traits on the medium-term outcome (6 months) of treatment for bipolar depression. One hundred and thirty-nine BD patients meeting criteria for a depressive episode were included in the study. SUD and PD were diagnosed according to structured interviews. Personality dimensions were evaluated by the Temperament and Character Inventory. Depressive severity over time was evaluated by the Hamilton Rating Scale for Depression. Neither PD nor SUD influenced the outcome of depression. Variables independently associated with a poor outcome were a high baseline severity and high scores for the temperamental trait of Harm Avoidance. Though several limitations characterize the present study, neurotic personality traits seem to be associated with a slower recovery from depressive symptoms in BD, independently from their initial severity.

Bipolar disorder: "pure" versus mixed depression over a 1-year follow-up.

OBJECTIVES: To compare two samples of Bipolar (BD) patients presenting "pure" (D) and mixed (Mx) depression to assess any difference in terms of clinical outcome, social functioning and quality of life during a 1-year follow-up. METHODS: A total of 114 depressed outpatients (HDRS > 13) were included. "Pure" depressed (D, n = 76) were divided from "mixed" depressed (Mx, n = 38) by the number of concomitant manic symptoms. All patients were evaluated by the Hamilton Depression Rating Scale (HDRS), the Hamilton Anxiety Rating Scale (HARS), the Young Mania Rating Scale (YMRS), the Global Assessment of Functioning (GAF), the Social Adjustment Self-reported Scale (SASS) and the Quality of Life Scale (QoL), at baseline and after 1, 3, 6 and 12 months of treatment. RESULTS: Mx patients were significantly younger at the onset of BD. Manic features persisted significantly higher in Mx than in D patients all over the follow-up period. Axis I comorbidities had a negative impact on the course of social functioning over the medium term period, while Mx patients showed a faster improvement in social adjustment than "pure" depressed patients. CONCLUSIONS: Mixed features may persist relatively stable throughout a depressive episode, having a negative impact over clinical and functional outcome, but not on social adjustment.

Factors associated with the course of symptoms in bipolar disorder during a 1-year follow-up: depression vs. sub-threshold mixed state.

BACKGROUND: Mixed mood states, even in their sub-threshold forms, may significantly affect the course and outcome of bipolar disorder (BD). AIM: To compare two samples of BD patients presenting a major depressive episode and a sub-threshold mixed state in terms of global functioning, clinical outcome, social adjustment and quality of life during a 1-year follow-up. METHODS: The sample was composed by 90 subjects (Group 1, D) clinically diagnosed with a major depressive episode and 41 patients (Group 2, Mx) for a sub-threshold mixed state. All patients were administered with a pharmacological treatment and evaluated for depressive, anxious and manic symptoms by common rating scales. Further evaluations included a global assessment of severity and functioning, social adjustment and quality of life. All evaluations were performed at baseline and after 1, 3, 6 and 12 months of treatment. RESULTS: The two groups were no different for baseline as well as improvement in global severity and functioning. Though clearly different for symptoms severity, the amount of change of depressive and anxiety symptoms was also no different. Manic symptoms showed instead a trend to persist over time in group 2, whereas a slight increase of manic symptoms was observed in group 1, especially after 6 months of treatment. Moreover, in group 1, some manic symptoms were also detected at the Young Mania Rating Scale (n = 24, 26.6%). Finally, improvement in quality of life and social adjustment was similar in the two groups, though a small trend toward a faster improvement in social adjustment in group 1. CONCLUSIONS: Sub-threshold mixed states have a substantial impact on global functioning, social adjustment and subjective well-being, similarly to that of acute phases, or at least major depression. In particular, mixed features, even in their sub-threshold forms, tend to be persistent over time. Finally, manic symptoms may be still often underestimated in depressive episodes, even in patients for BD.

Predictors of stigma in a sample of mental health professionals: Network and moderator analysis on gender, years of experience, personality traits, and levels of burnout.

BACKGROUND: Stigma is one of the most important barriers to help-seeking and to personal recovery for people suffering from mental disorders. Stigmatizing attitudes are present among mental health professionals with negative effects on the quality of health care. METHODS: Network and moderator analysis were used to identify what path determines stigma, considering demographic and professional variables, personality traits, and burnout dimensions in a sample of mental health professionals (n = 318) from six Community Mental Health Services. The survey included the Attribution Questionnaire-9, the Maslach Burnout Inventory, and the Ten-Item Personality Inventory. RESULTS: The personality trait of openness to new experiences resulted to determine lower levels of stigma. Burnout (personal accomplishment) interacted with emotional stability in predicting stigma, and specifically, for subjects with lower emotional stability lower levels of personal accomplishment were associated with higher levels of stigma. CONCLUSIONS: Some personality traits may be accompanied by better empathic and communication skills, and may have a protective role against stigma. Moreover, burnout can increase stigma, in particular in subjects with specific personality traits. Assessing personality and burnout levels could help in identifying mental health professionals at higher risk of developing stigma. Future studies should determine whether targeted interventions in mental health professionals at risk of developing stigma may be effective in stigma prevention.

Lithium Exposure During Pregnancy and the Postpartum Period: A Systematic Review and Meta-Analysis of Safety and Efficacy Outcomes.

OBJECTIVE: Uncertainty surrounds the risks of lithium use during pregnancy in women with bipolar disorder. The authors sought to provide a critical appraisal of the evidence related to the efficacy and safety of lithium treatment during the peripartum period, focusing on women with bipolar disorder and their offspring. METHODS: The authors conducted a systematic review and random-effects meta-analysis assessing case-control, cohort, and interventional studies reporting on the safety (primary outcome, any congenital anomaly) or efficacy (primary outcome, mood relapse prevention) of lithium treatment during pregnancy and the postpartum period. The Newcastle-Ottawa Scale and the Cochrane risk of bias tools were used to assess the quality of available PubMed and Scopus records through October 2018. RESULTS: Twenty-nine studies were included in the analyses (20 studies were of good quality, and six were of poor quality; one study had an unclear risk of bias, and two had a high risk of bias). Thirteen of the 29 studies could be included in the quantitative analysis. Lithium prescribed during pregnancy was associated with higher odds of any congenital anomaly (N=23,300, k=11; prevalence=4.1%, k=11; odds ratio=1.81, 95% CI=1.35-2.41; number needed to harm (NNH)=33, 95% CI=22-77) and of cardiac anomalies (N=1,348,475, k=12; prevalence=1.2%, k=9; odds ratio=1.86, 95% CI=1.16-2.96; NNH=71, 95% CI=48-167). Lithium exposure during the first trimester was associated with higher odds of spontaneous abortion (N=1,289, k=3, prevalence=8.1%; odds ratio=3.77, 95% CI=1.15-12.39; NNH=15, 95% CI=8-111). Comparing lithium-exposed with unexposed pregnancies, significance remained for any malformation (exposure during any pregnancy period or the first trimester) and cardiac malformations (exposure during the first trimester), but not for spontaneous abortion (exposure during the first trimester) and cardiac malformations (exposure during any pregnancy period). Lithium was more effective than no lithium in preventing postpartum relapse (N=48, k=2; odds ratio=0.16, 95% CI=0.03-0.89; number needed to treat=3, 95% CI=1-12). The qualitative synthesis showed that mothers with serum lithium levels <0.64 mEq/L and dosages <600 mg/day had more reactive newborns without an increased risk of cardiac malformations. CONCLUSIONS: The risk associated with lithium exposure at any time during pregnancy is low, and the risk is higher for first-trimester or higher-dosage exposure. Ideally, pregnancy should be planned during remission from bipolar disorder and lithium prescribed within the lowest therapeutic range throughout pregnancy, particularly during the first trimester and the days immediately preceding delivery, balancing the safety and efficacy profile for the individual patient.

Gender, Personality Traits and Experience With Psychiatric Patients as Predictors of Stigma in Italian Psychology Students.

A sample of undergraduate Psychology students (n = 1005), prevalently females (82.4%), mean age 20.5 (sd 2.5), was examined regarding their attitudes toward people suffering from mental illness. The survey instrument included a brief form for demographic variables, the Attribution Questionnaire-9 (AQ-9), the Ten Items Personality Inventory (TIPI), and two questions exploring attitudes toward open-door and restraint-free policies in Psychiatry. Higher levels of stigmatizing attitudes were found in males (Pity, Blame, Help, and Avoidance) and in those (76.5%) who had never had any experience with psychiatric patients (Danger, Fear, Blame, Segregation, Help, Avoidance and Coercion). A similar trend was also found in those who don't share the policy of no seclusion/restraint, while subjects who are favorable to open-door policies reported higher Coercion scores. No correlations were found between dimensions of stigma and personality traits. A machine learning approach was then used to explore the role of demographic, academic and personality variables as predictors of stigmatizing attitudes. Agreeableness and Extraversion emerged as the most relevant predictors for blaming attitudes, while Emotional Stability and Openness appeared to be the most effective contributors to Anger. Our results confirmed that a training experience in Psychiatry might successfully reduce stigma in Psychology students. Further research, with increased generalizability of samples and more reliable instruments, should address the role of personality traits and gender on attitudes toward people suffering from mental illness.

Exploring the relationships among personality traits, burnout dimensions and stigma in a sample of mental health professionals.

A sample of mental health professionals (n = 215) from six Community Mental Health Services was examined using a short version of the Attribution Questionnaire-27, the Maslach Burnout Inventory and the Ten Items Personality Inventory to detect possible associations among stigma, burnout dimensions and personality traits. The role of demographic and professional variables was also explored. Perception of workplace safety resulted to significantly affect attitudes toward patients. The concern about being assaulted and a low level of Personal Accomplishment were both related to avoidant attitudes, while the presence of procedures for managing the violent patient was associated with a higher level of Personal Accomplishment. Conversely, Emotional Stability and Openness to new experiences were inversely correlated with burnout dimensions and avoidant attitudes, respectively. Overall, our study supports the view of a significant association among some dimensions of stigma, burnout and personality factors. In particular, avoidant attitudes toward patients may be influenced by Personal Accomplishment and Openness to new experiences.

Effects of Dog-Assisted Therapy on Communication and Basic Social Skills of Adults With Intellectual Disabilities: A Pilot Study.

Thirty-nine adults with severe to profound intellectual disability (ID) were randomly assigned to either an experimental group (n = 21) or a control group (n = 18). Assessment was blinded and included selected items from the International Classification of Functioning, Disability and Health (ICF), the Behavioral Assessment Battery (BAB), and the Learning Accomplishment Profile (LAP). The experimental group, who attended a dog-assisted treatment intervention over a 20-week period, showed significant improvements in several cognitive domains, including attention to movement (BAB-AM), visuomotor coordination (BAB-VM), exploratory play (BAB-EP), and motor imitation (BAB-CO-MI), as well as in some social skills, as measured by LAP items. Effects were specific to the intervention and independent of age or basic level of disability.

A meta-analysis of cognitive performance in melancholic versus non-melancholic unipolar depression.

BACKGROUND: Recently there is increasing recognition of cognitive dysfunction as a core feature of Major Depressive Disorder (MDD). The goal of the current meta-analysis was to review and examine in detail the specific features of cognitive dysfunction in Melancholic (MEL) versus Non-Melancholic (NMEL) MDD. METHODS: An electronic literature search was performed to find studies comparing cognitive performance in MEL versus NMEL. A meta-analysis of broad cognitive domains (processing speed, reasoning/problem solving, verbal learning, visual learning, attention/working memory) was conducted on all included studies (n=9). Sensitivity and meta-regression analyses were also conducted to detect possible effects of moderator variables (age, gender, education, symptom severity and presence of treatments). RESULTS: MEL patients were older and more severly depressed than NMEL subjects. The MEL group was characterized by a worse cognitive performance in attention/working memory (ES=-0.31), visual learning (ES=-0.35) and reasoning/problem solving (ES=-0.46). No difference was detected in drug-free patients by sensitivity analyses. No effect was found for any of our moderators on the cognitive performance in MEL vs NMEL. CONCLUSION: Our findings seem to support a moderate but specific effect of melancholic features in affecting the cognitive performance of MDD, in particular as regards visual learning and executive functions.

A comparative meta-analysis of TEMPS scores across mood disorder patients, their first-degree relatives, healthy controls, and other psychiatric disorders.

BACKGROUND: The Temperament Evaluation Memphis, Pisa, Paris and San Diego Auto-questionnaire (TEMPS) is validated to assess temperament in clinical and non-clinical samples. Scores vary across bipolar disorder (BD), major depressive disorder (MDD), attention-deficit/hyperactivity disorder (ADHD), borderline personality disorder (BPD) and healthy controls (HCs), but a meta-analysis is missing. METHODS: Meta-analysis of studies comparing TEMPS scores in patients with mood disorders or their first-degree relatives to each other, or to a psychiatric control group or HCs. RESULTS: Twenty-six studies were meta-analyzed with patients with BD (n= 2025), MDD (n=1283), ADHD (n=56) and BPD (n=43), relatives of BD (n=436), and HCs (n=1757). Cyclothymic (p<0.001) and irritable TEMPS scores (p<0.001) were higher in BD than MDD (studies=12), and in MDD vs HCs (studies=8). Cyclothymic (p<0.001), irritable (p<0.001) and anxious (p=0.03) scores were higher in BD than their relatives, who, had higher scores than HCs. No significant differences emerged between ADHD and BD (studies=3); CONCLUSION: Affective temperaments are on a continuum, with increasing scores ranging from HCs through MDD to BD regarding cyclothymic and irritable temperament, from MDD through BD to HC regarding hyperthymic temperament, and from HC through BD relatives to BD regarding cyclothymic, irritable and anxious temperament. Depressive and anxious temperaments did not differ between BD and MDD, being nonetheless the lowest in HCs. BD did not differ from ADHD in any investigated TEMPS domain. LIMITATIONS: Different TEMPS versions, few studies comparing BD with ADHD or BPD, no correlation with other questionnaires.
