Psychiatric comorbidity and suicide risk in patients with chronic migraine.

The aim of this study was to explore the impact of mental illness among patients with migraine. We performed MedLine and PsycINFO searches from 1980 to 2008. Research has systematically documented a strong bidirectional association between migraine and psychiatric disorders. The relationship between migraine and psychopathology has often been clinically discussed rather than systematically studied. Future research should include sound methodologically-based studies focusing on the interplay of factors behind the relationship between migraine, suicide risk, and mental illness.

Predominant polarity and temperament in bipolar and unipolar affective disorders

INTRODUCTION Recently, the concept of predominant polarity (two-thirds of episodes belonging to a single pole of the illness) has been introduced to further characterise subtypes of bipolar disorders. This concept has been proven to have diagnostic and therapeutic implications, but little is known on the underlying psychopathology and temperaments. With this study, we aimed to further validate the concept and explore its relationships with temperament. METHODS This study enrolled 143 patients with bipolar or unipolar disorder. We analysed predominant polarity in the sample of bipolar I patients (N=124), focussing on those who showed a clear predominance for one or the other polarity, and distinguishing manic/hypomanic (MP) from depressive polarity (DP), and a unipolar major depression (UP) group (N=19),. We also assessed temperament by means of the Temperament Evaluation of the Memphis, Pisa, Paris, and San Diego Autoquestionnaire (TEMPS-A). RESULTS Over 55% of the bipolar I sample fulfilled predominant polarity criteria, with two-thirds of those meeting criteria for MP and one third for DP. MP and DP were similar in scoring higher than UP on the hyperthymic/cyclothymic scales of the TEMPS-A; the UP group scored higher on the anxious/depressive scales. DISCUSSION Our results show that both bipolar I MP and DP subgroups are temperamentally similar and different from UP. Depression in DP bipolar I patients should be viewed as the overlap of depression on a hyperthymic/cyclothymic temperament. These findings confirm the value of the predominant polarity concept as well as the importance of temperaments to separate bipolar from unipolar disorders.

Deep Transcranial Magnetic Stimulation for treatment-resistant bipolar depression: A case report of acute and maintenance efficacy

Deep Transcranial Magnetic Stimulation (dTMS) is currently being evaluated as a possible treatment for several neuropsychiatric disorders and has been demonstrated as a safe and effective procedure. This case presents a patient with bipolar depression that has been treated with 20 daily consecutive dTMS sessions and with one dTMS session every 2 weeks for the following 3 months. Depressive symptoms improved rapidly and response was maintained during the next 6 months; cognitive performances also improved. This report suggests that add-on dTMS may help overcoming drug-resistance in bipolar depression and protect from subsequent bipolar episodes of any polarity.

The wnt pathway in mood disorders

Objectives: To review the evidence of the involvement of the Wnt signalling pathway in mood disorders and in the action of drugs used to treat these disorders. Methods: We performed a careful PubMed search using as keywords all possible terms relevant to the Wnt pathway and crossing them with each of four areas, i.e., developmental effects, behavioural effects, mood disorders, and drugs used in their treatment. Papers were selected on the basis of their content and their data used for discussion. Results: Neurodevelopmental and behavioural data point to the possibility of involvement of the Wnt pathway in the pathophysiology of mood disorders. Clinical and post-mortem data are not sufficient to corroborate a definite role for Wnt alterations in any mood disorder. Combining genetic and pharmacological data, we may state that glycogen synthase kinase is the key molecule in bipolar disorder, as it is connected with many other signalling pathways that were shown to be involved in mood disorders, while Wnt molecules in the hippocampus appear to be mainly involved in depressive disorders. Conclusions: Altered Wnt signalling may play a role in the pathophysiology of mood disorders, although not a central one. It is premature to draw conclusions regarding the possible usefulness of Wnt manipulations in the treatment of mood disorders.

Factors affecting interindividual differences in clozapine response: a review and case report.

Clozapine is the most powerful new‐generation antipsychotic. Although this drug leads to great therapeutic benefits, two types of undesirable conditions frequently occur with its use: side effects and resistance to treatment. Therapeutic drug monitoring of clozapine would be very useful to avoid both these situations. The necessity of monitoring the therapy is the result of a wide interindividual variability in the metabolism of clozapine. In this review, we highlight all the conditions underlying this variability, analyzing them one by one.

Depression and affective temperaments are associated with poor health-related quality of life in patients with HIV infection

Introduction. Human immunodeficiency virus (HIV) represents one of the most chronic and debilitating infections worldwide. Hopelessness and affective temperaments (mood that is characteristic of an individual’s habitual functioning) may play important roles in the health-related quality of life (HRQoL) of patients with HIV. The purpose of this study was to examine affective temperaments in a sample of patients with HIV, the impact of hopelessness on HRQoL, and associations among HRQoL, hopelessness, and affective temperaments. Methods. The study involved 88 participants who were administered the Short- Form Health Survey (SF-36), the Beck Hopelessness Scale (BHS), the Suicidal History Self-Rating Screening scale (SHSS), the Gotland Male Depression Scale (GMDS), and the Temperament Evaluation of Memphis, Pisa, Paris and San Diego (TEMPS-A). Results. Patients with a poorer HRQoL reported more severe depression and hopelessness than patients with a higher HRQoL. Patients with a poorer HRQoL also had higher scores on all dimensions of the TEMPS-A with a depressive component compared to patients with a higher HRQoL. The small sample size in this study limits the generalizability of the findings. Conclusion. Patients with a poorer HRQoL were more depressed and also at an increased risk of suicide as indicated by the more severe hopelessness they reported compared to patients with higher HRQoL. These patients were also more likely to have depressive affective temperaments than those with a higher HRQoL. (Journal of Psychiatric Practice 2013;19:109–117)

Insight and awareness as related to psychopathology and cognition.

Background: Insight affects adherence and treatment outcome and relates to cognitive impairment and psychopathology. We investigated the relationship of insight with cognition in patients with major depression, schizophrenia and bipolar disorder in acute psychiatric care, long-term inpatient, and outpatient settings. Methods: Eighty-one patients (women, 59.5%; age, 45.9 ± 13.5 years; 27 in each setting group; 33.3% with DSM-IV bipolar disorder, 39.5% with unipolar major depression, and 27.2% with schizophrenia) underwent the Wisconsin Card Sorting Test (WCST) to test flexibility, clinician-rated Scale to Assess Unawareness of Mental Disorder (SUMD), and self-rated Insight Scale (IS) to assess insight/awareness. Results: Poor performance on the WCST correlated with higher SUMD scores such as current psychiatric illness unawareness, impaired symptom attribution, unawareness of medication effect, or of social consequences, but not with IS scores. The latter correlated with days on continuous treatment. Patients receiving psycho-education showed greater symptom awareness compared to patients treated with drugs alone. Cognitive flexibility and diagnostic category did not correlate. Poor insight corresponded with severe mental illness, particularly acute psychosis. Conclusions: Treatment setting specificity reflects psychopathology and severity. Insight is inversely proportional to illness severity and cognitive flexibility, which is also affected by psychopathology. Limitations comprise group heterogeneity, cross-sectional design, and limited sample size.

Group Psychoeducation Normalizes Cortisol Awakening Response in Stabilized Bipolar Patients under Pharmacological Maintenance Treatment

Patients in the TAU group participated to 21 weekly group meetings in which no special instruction was delivered. Assessments were performed before the beginning of PE (baseline) and at the end of the program (end point). Mental status was evaluated with the Hamilton Depression Rating Scale (HDRS, 21 items) and with the Young Mania Rating Scale (YMRS), while treatment compliance used the Adherence to Refills and Medications Scale (ARMS). Criteria for relapses were HDRS-21 >8 or YMRS >8. Saliva cortisol levels were assessed to evaluate the functional status of the HPA axis (CAR and cortisol circadian fluctuation). Samples were collected with the Salivette sampling device (Sarstedt, Italy) upon waking (08: 00 h ± 15 min), 30 and 60 min thereafter; additional samples were collected at 13: 00 and 20: 00 h. Patients avoided food, coffee or alcohol, teeth brushing, smoking or physical exercise for 60 min after waking and for 30 min prior to the other saliva collection. Saliva samples were recovered from a polyester swab by centrifugation at 3,000 rpm for 15 min and frozen at –20 ° C until analysis [7] . For each sample, duplicate measurements were performed on 25 μl of saliva using an immunoenzymatic Cortisol Saliva kit (Diametra, Italy) for the direct measurement of salivary cortisol (interassay coefficient of variation was <10%, and intra-assay coefficient of variation <7%, with a minimum detectable concentration of 0.5 ng/ml). For intergroup comparisons a Student t test was used, while χ 2

Relationship between temperament, depression, anxiety, and hopelessness in adolescents: A structural equation model

The purpose of this study was to test the validity of affective temperaments for predicting psychiatric morbidity and suicide risk, using a two-factor model to explain the relationships between temperament, anxiety, depression, and hopelessness. We investigated 210 high school students, 103 males and 107 females, 18-19 years old, who were administered self-report questionnaires to assess temperament (TEMPS-A), depression (BDI-II), anxiety (STAI) and hopelessness (BHS). The final structural model had a good fit with the data, with two factors significantly correlated, the first labeled unstable cyclothymic temperament including Dysthymic/Cyclothymic/Anxious temperament, Irritable temperament and Depression, and the second labeled Demoralization including Anxiety (State/Trait) and Hopelessness. Depression, anxiety and hopelessness are in a complex relationship partly mediated by temperament.

Suicide Attempters in the Emergency Department Before Hospitalization in a Psychiatric Ward

PURPOSE The study aims to compare the current suicidal risk of mood disorder patients who had just attempted suicide, as compared with those who had not attempted suicide, admitted to an emergency department (ED), and then hospitalized in a psychiatric unit. METHOD One hundred sixty-one mood disorder patients admitted to the ED were studied. A total of 22.4% of the participants were admitted for a suicide attempt. Patients were assessed for psychopathology and diagnosis. FINDINGS Suicide attempters were nearly 12 times more likely to report ongoing suicidal ideation during the psychiatric evaluation in the ED than nonattempters. Men and women did not differ for current and previous suicide attempts or for ongoing suicidal ideation. PRACTICAL IMPLICATIONS It is important to conduct a suicide risk assessment when individuals are admitted to an ED.
