The Mood Disorder Questionnaire is a useful screening instrument for bipolar I and II disorders in the community. The operating characteristics of the Mood Disorder Questionnaire in the general population differ substantially from its characteristics in outpatient psychiatric settings.

Aripiprazole (Abilify ® ) is an atypical antipsychotic drug that has been recently introduced for clinical use in the treatment of schizophrenia. Aripiprazole has a unique pharmacologic profile that includes partial agonism at several G-protein coupled receptors (GPCRs) [especially dopamine (D 2 ) and 5-HT 1A ] and antagonistic action at others (especially 5-HT 2A ). Clinical trials indicate that aripiprazole is effective in treating the positive and negative symptoms of schizophrenia. In short-term studies rapid onset of action (within one week) has been demonstrated. Preliminary data indicate that aripiprazole may also be effective in the treatment of manic symptoms of bipolar disorder. At recommended doses, aripiprazole appears to be safe and well tolerated in most adult patients with schizophrenia and schizoaffective disorder. There is only limited information available on the use of aripiprazole in children and adolescents, and pilot data suggest that a revised dosing strategy, based on weight, is indicated in this population. In the long-term studies, the use of aripiprazole was associated with continued efficacy, good compliance and increased time-to-relapse.Aripiprazole represents the first functionally selective atypical antipsychotic drug.

Adherence to treatment for bipolar disorder may be enhanced by interventions that address issues of appropriately taking medications to manage illness. For optimum outcomes, promotion of adherence must be integrated into the medication management of bipolar illness.

Although M(1) muscarinic receptor-selective partial agonists have shown promise in some preclinical antipsychotic drug models, these studies indicate that it is unlikely that the salutary actions of clozapine and similar atypical antipsychotic drugs are mediated solely by M(1) muscarinic receptor activation. It is possible, however, that the M(1) agonism of N-desmethylclozapine contributes to the uniquely beneficial actions of clozapine. Thus, these results are consistent with the notion that a balanced degree of activity at multiple biogenic amine receptors, including M(1) muscarinic agonism, is responsible for the uniquely beneficial actions of clozapine.

Larger CAG/CTG trinucleotide-repeat tracts in individuals affected with schizophrenia (SCZ) and bipolar affective disorder (BPAD) in comparison with control individuals have previously been reported, implying a possible etiological role for trinucleotide repeats in these diseases. Two unstable CAG/CTG repeats, SEF2-1B and ERDA1, have recently been cloned, and studies indicate that the majority of individuals with large repeats as detected by repeat-expansion detection (RED) have large repeat alleles at these loci. These repeats do not show association of large alleles with either BPAD or SCZ. Using RED, we have identified a BPAD individual with a very large CAG/CTG repeat that is not due to expansion at SEF2-1B or ERDA1. From this individual's DNA, we have cloned a highly polymorphic trinucleotide repeat consisting of (CTA)n (CTG)n, which is very long ( approximately 1,800 bp) in this patient. The repeat region localizes to chromosome 13q21, within 1.2 cM of fragile site FRA13C. Repeat alleles in our sample were unstable in 13 (5.6%) of 231 meioses. Large alleles (>100 repeats) were observed in 14 (1. 25%) of 1,120 patients with psychosis, borderline personality disorder, or juvenile-onset depression and in 5 (.7%) of 710 healthy controls. Very large alleles were also detected for Centre d'Etude Polymorphisme Humaine (CEPH) reference family 1334. This triplet expansion has recently been reported to be the cause of spinocerebellar ataxia type 8 (SCA8); however, none of our large alleles above the disease threshold occurred in individuals either affected by SCA or with known family history of SCA. The high frequency of large alleles at this locus is inconsistent with the much rarer occurrence of SCA8. Thus, it seems unlikely that expansion alone causes SCA8; other genetic mechanisms may be necessary to explain SCA8 etiology.

An emerging literature suggests that a collaborative care model, in which patients are active managers of their illness within a supportive social environment, is a beneficial approach for individuals with bipolar disorder. One aspect of treatment that is often suboptimal among individuals with bipolar disorder is treatment adherence. Establishing an ideal collaborative model may offer an opportunity to enhance treatment adherence among individuals with bipolar disorder. This paper presents results from a qualitative exploration of patients' attitudes towards the collaborative care model and how individuals with bipolar disorder perceive treatment adherence within the context of the collaborative care model. All participants were actively enrolled in outpatient treatment at a Community Mental Health Center and part of a larger study that evaluated the Life Goals Program, a manual-driven structured group psychotherapy for bipolar disorder that is based on the collaborative practice model. The Life Goals Program is designed to assist individuals to participate more effectively in the management of their bipolar illness and to improve their social and work-related problems. Individuals were queried regarding their opinions on the ingredients for an effective client-provider relationship. Quantitative data were collected on baseline treatment adherence as well. Individuals treated for bipolar disorder in a community mental health clinic identified 12 key elements that they felt were critical ingredients to a positive collaborative experience with their mental health care provider. The authors conceptualized these elements around 3 emerging themes: patient-centered qualities, provider-centered qualities, and interactional qualities. Individuals with bipolar disorder perceived the ideal collaborative model as one in which the individual has specific responsibilities such as coming to appointments and sharing information, whereas the provider likewise has specific responsibilities such as keeping abreast of current "state-of-the-arf" prescribing practices and being a good listener. Treatment adherence was identified as a self-managed responsibility within the larger context of the collaborative model. Individuals with bipolar disorder in this study placed substantial emphasis on the interactional component within the patient-provider relationship, particularly with respect to times when the individual may be more symptomatic and more impaired. It is important that clinicians and care providers gather information related to patients' perceptions of the patient-provider relationship when designing or evaluating services aimed at enhancing treatment adherence.
