Few studies have investigated the relationship between schizophrenia and frontotemporal dementia.

To investigate this relationship through a clinicopathological investigation of young-onset frontotemporal dementia and a review of the case literature.

Cases of young-onset frontotemporal dementia were identified within the local brain bank. The clinical course and pathological findings were collated. For the literature review, cases of frontotemporal dementia identified through Medline were selected according to defined criteria. The demographic, clinical, pathological and genetic characteristics of cases presenting with a psychotic illness were identified.

In the case series, 5 of 17 patients with frontotemporal dementia had presented with a psychotic illness (schizophrenia/schizoaffective disorder n=4, bipolar disorder n=1) an average of 5 years prior to the dementia diagnosis. Patients with schizophrenia exhibited changes consistent with TDP-43 and ubiquitin-positive frontotemporal dementia. In the cases review, a third of patients aged 30 years or under and a quarter of those aged 40 years or under had been diagnosed with psychosis at presentation.

Patients with young-onset frontotemporal dementia may be diagnosed with a psychotic illness years before the dementia diagnosis is made. These findings have implications for clinicians and for our further understanding of the neurobiology of psychotic illness.

The number of asylum seekers, refugees and internally displaced people worldwide is rising. Western countries are using increasingly restrictive policies, including the detention of asylum seekers, and there is concern that this is harmful.

To investigate mental health outcomes among adult, child and adolescent immigration detainees.

A systematic review was conducted of studies investigating the impact of immigration detention on the mental health of children, adolescents and adults, identified by a systematic search of databases and a supplementary manual search of references.

Ten studies were identified. All reported high levels of mental health problems in detainees. Anxiety, depression and posttraumatic stress disorder were commonly reported, as were self-harm and suicidal ideation. Time in detention was positively associated with severity of distress. There is evidence for an initial improvement in mental health occurring subsequent to release, although longitudinal results have shown that the negative impact of detention persists.

This area of research is in its infancy and studies are limited by methodological constraints. Findings consistently report high levels of mental health problems among detainees. There is some evidence to suggest an independent adverse effect of detention on mental health.

Allelic variation in the gene encoding brain-derived neurotrophic factor (BDNF) has been associated with affective disorders, but generally not schizophrenia. Brain-derived neurotrophic factor variants may help clarify the status of schizoaffective disorder.

To test the hypothesis that BDNF haplotypes are associated with psychiatric illness marked by a prominent affective component.

Frequencies of a 5-marker BDNF haplotype were examined in 600 White participants across four diagnostic categories and healthy controls.

Individuals with schizoaffective disorder and other affective disorders were significantly more likely to carry two copies of the most common BDNF haplotype (containing the valine allele of the Val66Met polymorphism) compared with healthy volunteers. Moreover, when compared with people with schizophrenia, individuals with schizoaffective disorder were significantly more likely to carry two copies of the common haplotype.

To our knowledge, this is the first candidate gene study to demonstrate association with schizoaffective disorder but not schizophrenia. Variation in the BDNF gene may be associated with the clinical phenotype of affective dysregulation across several DSM–IV diagnostic categories.

Studies demonstrating an association between childhood trauma and psychosis in adulthood have not systematically explored gender differences.

To investigate gender differences in the prevalence of childhood sexual and physical abuse among people with psychosis in comparison with healthy controls.

The Childhood Experiences of Care and Abuse Questionnaire was completed to elicit experiences of sexual and physical abuse during childhood in first-episode psychosis cases and population-based controls.

Among women, those in the cases group were twice as likely to report either physical or sexual abuse compared with controls following adjustment for all confounders. In particular, the effect of physical abuse in women was stronger and more robust than that for sexual abuse. A similar trend was found for psychotic-like experiences in the female control group. No association was found in men.

Reports of severe childhood physical or sexual abuse were associated with psychosis in women but not in men.

Whether the prevalence rates of common mental disorders can be compared across countries depends on the cultural validity of the diagnostic measures used.

To investigate the prevalence of Western and indigenously defined mental disorders among Vietnamese living in Vietnam and in Australia, comparing the data with an Australian-born sample.

Comparative analysis of three multistage population surveys, including samples drawn from a community living in the Mekong Delta region of Vietnam (n=3039), Vietnamese immigrants residing in New South Wales, Australia (n=1161), and an Australian-born population (n=7961). Western-defined mental disorders were assessed by the Composite International Diagnostic Interview (CIDI) 2.0 and included DSM–IV anxiety, mood and substance use disorders as well as the ICD–10 category of neurasthenia. The Vietnamese surveys also applied the indigenously based Phan Vietnamese Psychiatric Scale (PVPS). Functional impairment and service use were assessed.

The prevalence of CIDI mental disorders for Mekong Delta Vietnamese was 1.8% compared with 6.1% for Australian Vietnamese and 16.7% for Australians. Inclusion of PVPS mental disorders increased the prevalence rates to 8.8% for Mekong Delta Vietnamese and 11.7% for Australian Vietnamese. Concordance was moderate to good between the CIDI and the PVPS for Australian Vietnamese (area under the curve (AUC)=0.77) but low for Mekong Vietnamese (AUC=0.59). PVPS- and CIDI-defined mental disorders were associated with similar levels of functional impairment.

Cultural factors in the expression of mental distress may influence the prevalence rates of mental disorders reported across countries. The findings have implications for assessing mental health needs at an international level.

There is great heterogeneity of clinical presentation and outcome in paediatric depression.

To identify which clinical and environmental risk factors at baseline and during treatment predicted major depression at 28-week follow-up in a sample of adolescents with depression.

One hundred and ninety-two British adolescents with unipolar major depression were enrolled in a randomised controlled trial (the Adolescent Depression Antidepressants and Psychotherapy Trial, ADAPT). Participants were treated for 28 weeks with routine psychosocial care and selective serotonin reuptake inhibitors (SSRIs), with half also receiving cognitive–behavioural therapy (CBT). Full clinical and demographic assessment was carried out at baseline and 28 weeks.

Depression at 28 weeks was predicted by the additive effects of severity, obsessive–compulsive disorder and suicidal ideation at entry together with presence of at least one disappointing life event over the follow-up period.

Clinicians should assess for severity, suicidality and comorbid obsessive–compulsive disorder at presentation and should monitor closely for subsequent life events during treatment.

People with severe depressive illness have raised levels of cortisol and reduced glucocorticoid receptor function.

To obtain a physiological assessment of hypothalamic–pituitary–adrenal (HPA) axis feedback status in an in-patient sample with depression and to relate this to prospectively determined severe treatment resistance.

The prednisolone suppression test was administered to 45 in-patients with depression assessed as resistant to two or more antidepressants and to 46 controls, prior to intensive multimodal in-patient treatment.

The patient group had higher cortisol levels than controls, although the percentage suppression of cortisol output after prednisolone in comparison with placebo did not differ. Nonresponse to in-patient treatment was predicted by a more dysfunctional HPA axis (higher cortisol levels postprednisolone and lower percentage suppression).

In patients with severe depression, HPA axis activity is reset at a higher level, although feedback remains intact. However, prospectively determined severe treatment resistance is associated with an impaired feedback response to combined glucocorticoid and mineralocorticoid receptor activation by prednisolone.

An association between depression and headache is well established, but the specificity to migraine is unclear.

To investigate the specificity of the association of depression and migraine.

People with recurrent depression (n=1259) were compared with psychiatrically healthy controls (n=851) to investigate headache defined according to International Headache Society criteria in each group.

All headache types were more prevalent in the case group than in the controls. However, the strongest association was between depression and migraine with aura (OR=5.6). Among participants with recurrent headaches, migraine with aura (but not other forms of headache) was highly significantly associated with depression.

The data suggest that not only is there a general relationship between headache and depression but also that among people with recurrent headache there is a specific association between depression and migraine with aura. The association is likely to be explained by overlapping aetiological risk factors.

Animal experimental studies have prompted concerns that widespread use of 3,4-methylenedioxymethamphetamine (MDMA; ‘ecstasy’) by young people may pose a major public health problem in terms of persistent serotonin neurotoxicity.

To determine the status of brain serotonin neurons in a group of abstinent MDMA users.

We assessed the integrity of brain serotonin neurons by measuring serotonin transporter (SERT) binding using positron emission tomography (PET) and [11C]DASB in 12 former MDMA users, 9 polydrug users who had never taken MDMA and 19 controls who reported no history of illicit drug use.

There was no significant difference in the binding potential of [11C]DASB between the groups in any of the brain regions examined.

To the extent that [11C]DASB binding provides an index of the integrity of serotonin neurons, our findings suggest that MDMA use may not result in long-term damage to serotonin neurons when used recreationally in humans.

Whether the development of tardive dyskinesia leads to an increase in mortality is still unclear.

To explore the relationship between tardive dyskinesia and mortality over a 10-year period, using the National Death Index.

Death certificates were obtained from the National Death Index on 1621 people repeatedly assessed for tardive dyskinesia by trained raters. Variables with the potential for influencing survival time were also investigated.

Tardive dyskinesia was significantly associated with an increase in mortality (P<0.001), but this association became non-significant when drug course and age were entered in the regression analysis. Those who had taken only conventional antipsychotics were twice as likely to die compared with those taking atypical agents (P<0.02). For those aged 53–65 years, conventional agents were associated with a sevenfold increase in mortality.

Older individuals with tardive dyskinesia treated with conventional antipsychotics appear to have a shortened survival time.

Child and adolescent mental health disorders are present in around 10% of the population. Research indicates that many young people possess negative attitudes towards mental health difficulties among peers.

To assess the impact of a mental health teaching programme on adolescent pupils' understanding.

Two-group pre-test–post-test control group study in two English secondary schools. Experimental classes (School E) received a six-lesson teaching intervention on mental health; control classes (School C) did not. Participants were 14- and 15-year-old pupils. The intervention consisted of six lessons on mental health issues common to young people: stress; depression; suicide/self-harm; eating disorders; being bullied; and intellectual disability. School C was given access to these lesson plans and materials on completion of the study. Understanding was measured at two time points, Time 1 (T1) and Time 2 (T2), 8 months apart, by a Mental Health Questionnaire. Behavioural, emotional and relationship strengths and difficulties were measured by the self-rated Strengths and Difficulties Questionnaire (SDQ) with five subscales: hyperactivity, emotional symptoms, conduct problems, peer problems and prosocial behaviour.

At T2, pupils in School E compared with those in School C showed significantly more sensitivity and empathy towards people with mental health difficulties. They also used significantly fewer pejorative expressions to describe mental health difficulties. There was a significant reduction in SDQ scores on conduct problems and a significant increase on prosocial behaviour among School E pupils compared with controls. Pupils valued the intervention highly, in particular the lessons on suicide/self-harm.

Teaching 14- and 15-year-olds about mental health difficulties helps to reduce stigma by increasing knowledge and promoting positive attitudes. The intervention also reduced self-reported conduct problems and increased prosocial behaviour. Generally, participating pupils were positive about the importance of lessons on mental health, and said that they had learnt much about the lesson topics.
