Pooled complexed responses were contrasted against pooled neutral ones. The fMRI activation pattern of this generic 'complexed response' was very strong (corrected Z scores ranging from 4.90 to 5.69). The activation pattern in each hemisphere includes mirror neurone areas that track 'otherness' (perspectival empathy), anterior insula (both self-awareness and emotional empathy), and cingulated gyrus (self-awareness and conflict-monitoring). These are the sites described by Siegel and colleagues as the 'resonance circuitry' in the brain which is central to mindfulness (awareness of self) and empathy (sense of the other), negotiations between self awareness and the 'internal other'. But there is also an interhemispheric dialogue. Within 3 seconds, the left hemisphere overrides the right (at least in our normal subjects). Mindfulness and empathy are central to good psychotherapy, and complexes can be windows of opportunity if left-brain hegemony is resisted. This study sets foundations for further research: (i) QEEG studies (with their finer temporal resolution) of complexed responses in normal subjects (ii) QEEG and fMRI studies of complexed responses in other conditions, like schizophrenia, PTSD, disorders of self organization.

Design and setting: Postal survey of GPs in the catchment area (inner north Brisbane, Queensland), September to November 2003; and assessment of referrals, March to August 2003. Main outcome measures: Patient referrals, satisfaction among GPs who had referred, and awareness and opinions of the service among GPs who had not referred, compared with results of a similar survey conducted before marketing. Results: In the 6 months after marketing, 43 patients were referred by 23 GPs, an average of 7.2 patients per month, compared with 2.5 per month in the first 12 months of the service. Survey responses were received from 13 of 36 GPs who had referred patients and 97 of 282 GPs who had not (response rate, 35%). Satisfaction among GPs who had referred remained high, and 12/13 felt the service should continue. Among GPs who had not referred, 76% were aware of the service, up from 26% in the previous survey, and 99% liked the concept of the service. Conclusion: Given the ongoing low utilisation of this service, we question whether this model is accepted by most GPs in our district. Possibly, they prefer more traditional models, where treatment is taken over by psychiatrists in the public or private system. We believe there is a need to increase the capacity and scope of publicly funded MJA 2005; 183: 87-90 services to treat mental health problems.

Objective: The goal of this study was to assess the efficacy and safety of olanzapine versus those of haloperidol during transition from IM to PO therapy. We used additional data from a previously reported trial to test the hypothesis that the reduction in agitation achieved by IM olanzapine 10 mg or IM haloperidol 7.5 mg would be maintained following transition to 4 days of PO olanzapine or PO haloperidol (5-20 mg/d for both). We also hypothesized that olanzapine would maintain its more favorable extrapyramidal symptom (EPS) safety profile. Methods: This was a multinational (hospitals in 13 countries), double-blind, randomized, controlled trial. Acutely agitated inpatients with schizophrenia were treated with 1 to 3 IM injections of olanzapine 10 mg or haloperidol 7.5 mg over 24 hours and were entered into a 4-day PO treatment period with the same medication (5-20 mg/d for both). The primary efficacy measurement was reduction in agitation, as measured by the Positive and Negative Syndrome Scale-Excited Component (PANSS-EC) score. Adverse events and scores on EPS rating scales were assessed. Results: A total of 311 patients (204 men, 107 women; mean [SD] age, 38.2 [11.6] years) were enrolled (131, 126, and 54 patients in the olanzapine, halo

Patients (n = 311) with acute schizophrenia were randomly allocated (2:2:1) to receive i.m. olanzapine (10.0 mg, n = 131), i.m. haloperidol (7.5 mg, n = 126), or i.m. placebo (n = 54). After the first injection, i.m. olanzapine was comparable to i.m. haloperidol and superior to i.m. placebo for reducing mean change scores from baseline on the Brief Psychiatric Rating Scale (BRPS) Positive at 2 hours (-2.9 olanzapine, -2.7 haloperidol, and -1.5 placebo) and 24 hours (-2.8 olanzapine, -3.2 haloperidol, and -1.3 placebo); the BPRS Total at 2 hours (-14.2 olanzapine,-13.1 haloperidol, and -7.1 placebo) and 24 hours (-12.8 olanzapine, -12.9 haloperidol, and -6.2 placebo); and the Clinical Global Impressions (CGI) scale at 24 hours (-0.5 olanzapine, -0.5 haloperidol, and -0.1 placebo).

This concept has made it possible to develop therapeutic approaches for PTSD that include medication and psychotherapy options. In this article we summarize research studies on pharmacotherapies for PTSD and review new findings in the neurobiology of PTSD that are promoting the development of targeted treatment options. Research findings that have improved our understanding of psychobiological abnormalities associated with PTSD offer clinicians improved treatment strategies. We review those findings, the developments in the medication management of PTSD and common co-occurring disorders, and new areas of pharmacological research on PTSD treatment.

This study investigated the effect of diagnosis, depressive symptoms and history of alcohol or tobacco abuse or dependence on the d-fenfluramine test in combatrelated post-traumatic stress disorder (PTSD). Male, non-hospitalized combat-exposed veterans diagnosed with PTSD (DSM-III-R) and a similarly aged combat-exposed control group were assessed for both PTSD and depressive symptoms and prolactin responses to a 30-mg d-fenfluramine challenge test. Ninetyfive subjects were studied ; 23 were controls, 46 subjects met the criteria for current PTSD and 26 for past PTSD. There were no significant differences between the three groups for baseline prolactin, peak prolactin, and time to reach peak, delta prolactin or area under the curve of the prolactin vs. time curve. Depressive symptoms and history of alcohol or tobacco abuse or dependence did not have a confounding effect on the prolactin responses to d-fenfluramine. This study suggests that a blunted prolactin response to d-fenfluramine may be a consequence of combat exposure rather than PTSD. To confirm this, further studies involving both healthy and combat-exposed control groups in addition to subjects with PTSD of similar ages are required.

Retrospective cohort study SETTING: Australia. Administrative claims data from the Australian Government Department of Veterans' Affairs were used. Male Vietnam veterans aged 55 to 65 at baseline (2001-02) with no preexisting dementia diagnosis (N = 15,612). The association between PTSD and dementia was assessed over 12 years of follow-up. Dementia was identified as a hospital diagnosis, dementia record in service disability data, or dispensing of medicines for dementia. Cox-proportional hazards models were used, with age as the time-scale. Results were stratified according to baseline antipsychotic use. No greater risk of dementia was observed with PTSD. In veterans who received antipsychotics, dementia risk was significantly higher than in those who did not (hazard ratio (HR) = 2.1, 95% confidence interval (CI) = 1.4-3.3). Dementia risk w...

PTSD is considered to be present if the sufferer develops persistent re-experiencing, avoidance and emotional numbing and symptoms of increased arousal not present before the sufferer was exposed to a traumatic incident. PTSD is now classified in DSM-5 as a trauma- and stressor-related disorder, unlike DSM-IV where it was previously categorized as an anxiety disorder, lending it more prominence now as a stress-related condition. However, it remains placed near the anxiety, obsessive compulsive and dissociative disorders in recognition of the close relationship with these other diagnoses. The nosology of PTSD is interesting as the symptoms can vary considerably. Some individuals with PTSD exhibit anxious or fear-based symptoms, while others can experience anhedonic, dysphoric, aggressive or dissociative symptoms...

At follow-up, fifteen months later, the prevalence of depressive disorder had declined substantially, to 12 percent overall. Major depression was characterized by an average duration of thirty-nine weeks, a mortality rate of 23 percent and was associated with positive family history of affective or anxiety disorder. Among patients with left hemisphere lesions, major depression was associated with cognitive impairment. Minor depression had a shorter average duration (twelve weeks) and was more common in males. These two syndromes may define distinct types of post-stroke depression with implications for treatment interventions.

The authors examined the effect of depression on mortality among a group of stroke patients followed up for 10 years. A consecutive series of 103 patients was assessed for major or dysthymic (minor) depression approximately 2 weeks after stroke with the use of a structured mental status examination and DSM-III diagnostic criteria. Vital status was determined for 91 of these patients 10 years later. Forty-eight (53%) of the 91 patients had died. Patients with diagnoses of either major or minor depression were 3.4 times more likely to have died during the follow-up period than were nondepressed patients, and this relationship was independent of other measured risk factors such as age, sex, social class, type of stroke, lesion location, and level of social functioning. The mortality rate among depressed patients with few social contacts was especially high: over 90% had died. These results indicate that depressed mood following stroke is associated with an increased risk of subsequent mortality. Patients who are depressed and socially isolated seem to be particularly vulnerable.
