Antipsychotic drugs block dopamine receptors and are used to manage psychosis as well as other mental illnesses that may or may not have psychotic features, such as bipolar disorders and major depressive disorder. First-generation antipsychotic drugs are more likely to cause adverse effects such as extrapyramidal symptoms and tardive dyskinesia. Adverse effects of second-generation antipsychotic drugs typically are related to metabolic abnormalities such as weight gain, abnormal blood glucose levels, and elevated lipid levels...

Psychosis is one of the most common conditions in later life, with dementia being a main contributing factor. The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), now categorizes the various types of dementia as neurocognitive disorders. Alzheimer disease is a common cause of dementia and psychosis. Psychosis also is seen in patients with vascular dementia and dementia with Lewy bodies. Psychosis can be primary, caused by a psychiatric disorder listed in the DSM-5, or secondary, due to a medical or neurologic condition...

Schizophrenia is the most common psychotic illness, typically appearing between the late teenage years and the mid-30s. The first episode of psychosis may be preceded by a prodromal period. Schizophrenia symptoms fall into six common symptom clusters: delusions and hallucinations, disorganization of speech, cognitive dysfunction, negative symptoms, affective symptoms, and motor system abnormalities. The diagnosis is based on criteria in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, including exclusion of other possible medical or psychiatric etiologies of psychosis...

BACKGROUND: Of young people with first episode psychosis (FEP), over half report exposure to childhood trauma and consequent co-morbid post-traumatic stress disorder (PTSD) or symptoms. Currently no evidence-based interventions exist for PTSD in FEP. Clinicians report concerns that trauma-focused interventions with young people with FEP could result in distress and symptom exacerbation. Scant research suggests that talking about trauma in therapy can be distressing for some people. AIMS: To explore young people's reactions to a trauma-focused treatment for PTSD in FEP...

BACKGROUND: The liability-threshold model of psychosis risk predicts stronger phenotypic manifestation of the polygenic risk score (PRS) in the healthy relatives of patients, as compared with healthy comparison subjects. METHODS: First-degree relatives of patients with psychotic disorder (871 siblings and 812 parents) and healthy comparison subjects (n = 523) were interviewed three times in 6 years. Repeated measures of two psychosis phenotypes, the Community Assessment of Psychic Experiences (CAPE; self-report - subscales of positive, negative and depressive symptoms) and the Structured Interview for Schizotypy - Revised (SIS-R; clinical interview - subscales of positive and negative schizotypy), were examined for association with PRS...

BACKGROUND: Autism Spectrum Disorders (ASD) and psychosis share deficits in social cognition. The insular region has been associated with awareness of self and reality, which may be basic for proper social interactions. METHODS: Total and regional insular volume and thickness measurements were obtained from a sample of 30 children and adolescents with ASD, 29 with early onset first-episode psychosis (FEP), and 26 healthy controls (HC). Total, regional, and voxel-level volume and thickness measurements were compared between groups (with correction for multiple comparisons), and the relationship between these measurements and symptom severity was explored...

Evidence suggests that attachment styles may influence subclinical psychosis phenotypes (schizotypy) and affective disorders and may play a part in the association between psychosis and childhood adversity. However, the role of attachment in the initial stages of psychosis remains poorly understood. Our main aim was to describe and compare attachment styles in 60 individuals at ultra high risk for psychosis (UHR) and a matched sample of 60 healthy volunteers (HV). The HV had lower anxious and avoidant attachment scores than the UHR individuals (p < ...

Hashimoto encephalopathy (HE) is believed to be an immune-mediated disorder associated with Hashimoto's thyroiditis. It was suggested that neuropsychiatric symptoms, the presence of antithyroid antibody, and good response to steroids were important for the diagnosis of HE. It has been reported that homovanillic acid (HVA) and 3-methoxy-4-hydroxyphenylglycol (MHPG), which are monoamine metabolites of dopamine and noradrenaline, respectively, are the possible biomarkers of neuropsychiatric diseases. We report a case of Hashimoto encephalopathy, in which we longitudinally measured the plasma levels of monoamine metabolites...

Cognitive behavioural therapy (CBT) for psychosis (CBTp) aims to lower the stress of psychotic symptoms. Given that the pituitary is involved in stress regulation, CBT-led stress reduction may be accompanied by a change in pituitary volume. This study aimed to determine whether CBTp reduces pituitary volume in schizophrenia. The relation between pre-therapy memory and CBTp-led pituitary volume change was also examined given that poor memory relates to a blunted cortisol awakening response, denoting impaired stress response, in schizophrenia...

BACKGROUND: 22q11.2 Deletion Syndrome (22q11.2DS) is one of the strongest known genetic risk factors for developing schizophrenia. Individuals with 22q11.2DS have high rates of neurodevelopmental disorders in childhood, while in adulthood ∼25% develop schizophrenia. Similar to the general population, high rates of comorbidity are common in 22q11.2DS. Employing a dimensional approach where psychopathology is examined at the symptom-level as complementary to diagnostic categories in a population at such high genetic risk for schizophrenia can help gain a better understanding of how psychopathology is structured as well as its genetic underpinnings...

Wilson disease - can present with such a variety of psychiatric and cognitive symptoms that it has been named the "great masquerader." Symptoms may include cognitive deficits, impairment of executive function, mood disturbance or psychosis. These impairments may occur in different stages of the disease and with varying intensity in individual patients. This chapter reviews the literature and authors' clinical experiences of the assessment, mechanism, and prevalence of cognitive and psychiatric pathology occurring in Wilson disease...

OBJECTIVE: Increasing evidence implicates advanced paternal age at offspring birth in neuropsychiatric disorders. Advanced maternal age has also been associated with schizophrenia and other neurodevelopmental disorders, whereas younger maternal age has been linked with behavioral disorders. Few studies have considered the specificity of the associations with respect to comorbidity. In addition, most prior studies have been conducted in clinical samples or registries that may reflect more severe forms of psychopathology...

BACKGROUND: We aimed to determine the prognostic accuracy of the Basel Screening Instrument for Psychosis (BSIP) in terms of specificity, sensitivity, positive and negative predictive value by following up individuals that were initially not considered to be at increased risk of psychosis based on the BSIP. Moreover, clinical characteristics of these individuals were examined given the relative lack of such information in the literature. METHODS: As part of the "Früherkennung von Psychosen" (FePsy) study, 87 individuals were screened with the BSIP...

OBJECTIVE: Social Security Administration (SSA) disability benefits are an important source of income for people with psychoses and confer eligibility for health insurance. The authors examined the impact of coordinated specialty care on receipt of such benefits in first-episode psychosis, along with the correlates and consequences of receiving them. METHOD: The Recovery After an Initial Schizophrenia Episode-Early Treatment Program (RAISE-ETP) study, a 34-site cluster-randomized trial, compared NAVIGATE, a coordinated specialty care program, to usual community care over 2 years...

Psychiatric symptoms must be considered in patients with refractory temporal lobe epilepsy after epilepsy surgery. The main objectives of our study were to describe clinical and socio-demographical characteristics of a cohort of patients with pharmacoresistant temporal lobe epilepsy who underwent temporal lobe epilepsy surgery, and moreover, to evaluate possible risk factors for developing psychiatric symptoms. In order to achieve those goals, we conducted a prospective evaluation of psychopathology throughout the first year after surgery in a clinical sample of 72 patients, by means of three clinical rated measures; the Hamilton Anxiety Rating Scale (HARS), the Hamilton Depression Rating Scale (HDRS), and the Brief Psychiatric Rating Scale (BPRS)...

A relatively large number of studies have investigated the power of structural magnetic resonance imaging (sMRI) data to discriminate patients with schizophrenia from healthy controls. However, very few of them have also included patients with bipolar disorder, allowing the clinically relevant discrimination between both psychotic diagnostics. To assess the efficacy of sMRI data for diagnostic prediction in psychosis we objectively evaluated the discriminative power of a wide range of commonly used machine learning algorithms (ridge, lasso, elastic net and L0 norm regularized logistic regressions, a support vector classifier, regularized discriminant analysis, random forests and a Gaussian process classifier) on main sMRI features including grey and white matter voxel-based morphometry (VBM), vertex-based cortical thickness and volume, region of interest volumetric measures and wavelet-based morphometry (WBM) maps...

BACKGROUND: Many studies have concluded that cannabis use disorder (CUD) negatively influences outcomes in first-episode psychosis (FEP). However, few have taken into account the impact of concurrent misuse of other substances. METHODS: This 2-year, prospective, longitudinal study of FEP patients, aged between 18 and 30 years, admitted to early intervention programs in Montreal, Quebec, Canada, examined the specific influence of different substance use disorders (SUD) (alcohol, cannabis, cocaine, amphetamines) on service utilization, symptomatic and functional outcomes in FEP...

INTRODUCTION: Biases in causal attributions and evidence integration have been implicated in delusions, but have not been investigated simultaneously to examine additive or multiplicative effects. It was hypothesised that paranoid delusions would correlate with self-serving and personalising biases ("defence" model of paranoia), particularly when these biases were disconfirmed. METHODS: Constrained principal component analysis was used to investigate differences between schizophrenia patients (paranoid vs...
