BACKGROUND: The duration of untreated psychosis (DUP) has been widely studied. However, for individuals with attenuated psychosis syndrome (APS), it is unclear whether the duration of untreated prodromal symptoms (DUPrS) also has a negative effect on the progression of psychosis. Our aim was to identify demographic and clinical factors contributing to the DUPrS in a large sample of individuals with APS, and to evaluate the association between DUPrS and the conversion to psychosis. METHOD: A sample of 391 individuals with APS, who were identified through a structured interview for prodromal syndromes, were included in this study, of whom a total of 334 patients had completed at least a 1-year clinical follow-up...

BACKGROUND AND AIMS: Adolescents at clinical high risk (CHR) for psychosis, as defined by the presence of attenuated psychosis symptoms (APS), exhibit increased levels of suicidal ideation and behaviour. However, no research thus far has examined the link between basic self-disturbances (SDs), an established marker for CHR, and suicidality/self-harm in this population. The goal of this pilot study was to assess the association between SD, depression and suicidal ideation and behaviour among non-help-seeking adolescents from the community...

Although individuals at clinical high risk (CHR) for psychosis exhibit a psychosis-risk syndrome involving attenuated forms of the positive symptoms typical of schizophrenia (SZ), it remains unclear whether their resting-state brain intrinsic functional networks (INs) show attenuated or qualitatively distinct patterns of functional dysconnectivity relative to SZ patients. Based on resting-state functional magnetic imaging data from 70 healthy controls (HCs), 53 CHR individuals (among which 41 subjects were antipsychotic medication-naive), and 58 early illness SZ (ESZ) patients (among which 53 patients took antipsychotic medication) within five years of illness onset, we estimated subject-specific INs using a novel group information guided independent component analysis (GIG-ICA) and investigated group differences in INs...

Background: High rates of non-psychotic psychopathological symptoms have been observed in clinical population at clinical high risk (CHR) for psychosis. These comorbid disorders affected the baseline functional level of CHR patients. However, little is known about the comorbid mental disorder in CHR individuals in non-clinical adolescent population. This study aimed to investigate the comorbid mental disorder in non-clinical CHR adolescents and the impact on attenuated psychosis symptoms (APS) as well as clinical outcome...

AIM: The goal of this pilot study was to assess the association between basic self-disturbance (SD) and deficits in neurocognitive and metacognitive functioning among help-seeking adolescents with and without attenuated psychosis syndrome (APS). METHODS: Sixty-one non-psychotic, help-seeking adolescents (age 13-18) were assessed with the examination of anomalous self-experience, the structured interview for prodromal syndromes and a new metacognitive approach to neurocognitive assessment applied to two non-social (executive functions and verbal memory) and two social (theory of mind and emotion recognition) domains...

Individuals at clinical high-risk (CHR) for psychosis are characterized by attenuated psychotic symptoms. Only a minority of CHR individuals convert to full-blown psychosis. Therefore, there is a strong interest in identifying neurobiological abnormalities underlying the psychosis risk syndrome. Dynamic functional connectivity (DFC) captures time-varying connectivity over short time scales, and has the potential to reveal complex brain functional organization. Based on resting-state functional magnetic resonance imaging (fMRI) data from 70 healthy controls (HCs), 53 CHR individuals, and 58 early illness schizophrenia (ESZ) patients, we applied a novel group information guided ICA (GIG-ICA) to estimate inherent connectivity states from DFC, and then investigated group differences...

Recent research suggests that trauma history (TH) is a strong socio-environmental risk factor for the development of psychosis. While reported rates of childhood trauma are higher among individuals at clinical high-risk (CHR) for psychosis than in the general population, little research has explored the effects of trauma upon the severity of attenuated positive symptoms. We aimed to explore the specific relationships between TH and baseline symptom severity; likelihood of conversion to full-blown psychosis; suicidal ideation (SI); and suicidal behavior (SB) in a cohort of 200 help-seeking CHR individuals...

Recent research suggests that perceptual abnormalities are a group of diverse experiences, which have been associated with trauma, cannabis use, and anxiety. Of the attenuated psychotic symptoms that are present in youth at clinical high risk (CHR) of psychosis, perceptual abnormalities tend to be one of the most frequently endorsed symptoms. However, very few studies have explored perceptual abnormalities and their relationships with the above environmental and affective factors in a CHR sample. Four hundred and forty-one CHR individuals who met criteria for attenuated psychotic symptom syndrome (APSS) determined by the Structured Interview for Psychosis-risk Syndromes (SIPS) were assessed on the content of their perceptual abnormalities, early traumatic experience, cannabis use and self-reported anxiety...

BACKGROUND: Attenuated positive symptom syndrome (APSS), characterized by 'putatively prodromal' attenuated psychotic-like pathology, indicates increased risk for psychosis. Poor premorbid social adjustment predicts severity of APSS symptoms and predicts subsequent psychosis in APSS-diagnosed individuals, suggesting application for improving detection of 'true' prodromal youth who will transition to psychosis. However, these predictive associations have not been tested in controls and therefore may be independent of the APSS diagnosis, negating utility for improving prediction in APSS-diagnosed individuals...

Individuals with Clinical High-Risk state for Psychosis (CHR-P) are reported to exhibit impaired quality of life (QOL) similar to that observed in schizophrenia, but its determinants remain unclear. We investigated the QOL of 33 subjects with CHR-P, 45 patients with schizophrenia, and 63 healthy subjects using the Quality of Life Scale (QLS). The CHR-P and schizophrenia groups were administered the Brief Assessment of Cognition in Schizophrenia (BACS), the Schizophrenia Cognition Rating Scale (SCoRS), and the Social and Occupational Functioning Assessment Scale (SOFAS) for socio-cognitive functions; and the Positive and Negative Syndrome Scale (PANSS) and the State-Trait Anxiety Inventory for clinical symptoms...

22q11.2 deletion syndrome (22q11DS) represents a homogeneous model of schizophrenia particularly suitable for the search of neural biomarkers of psychosis. Impairments in structural connectivity related to the presence of psychotic symptoms have been reported in patients with 22q11DS. However, the relationships between connectivity changes in patients with different symptomatic profiles are still largely unknown and warrant further investigations. In this study, we used structural connectivity to discriminate patients with 22q11DS with (N = 31) and without (N = 31) attenuated positive psychotic symptoms...

AIM: There is an interest in the transition to psychosis for those at clinical high risk of developing psychosis. This transition is typically determined by a change in severity of the attenuated symptoms as they reach a psychotic level. However, any concomitant change in the content of such symptoms has not been examined. The current study aimed to examine potential qualitative changes in the symptom content from a clinical high-risk state to a first episode of psychosis. METHODS: Sixty-seven individuals, who had been identified as meeting the attenuated psychotic syndrome based on the Structured Interview of Psychosis-Risk Syndromes and who later developed a full-blown psychosis were included in the study...

There is a lack of insight into the relationships between violent ideation, violent behavior, and early, particularly attenuated, psychosis. Our aims were to examine the relationships between baseline violent behavior and violent ideation and outcome violent behavior and conversion to psychosis in at-risk individuals. We longitudinally assessed 200 individuals at clinical high risk for psychosis for violent ideation and violent behavior using the Structured Interview for Psychosis-Risk Syndromes (SIPS), and rated these according to MacArthur Community Violence categories...

In recent years an increasing number of studies focus on the issue of early diagnosis and intervention. At the same time, a large number of special service units for early psychosis have been established around the world especially in Australia, USA, UK, Germany etc. Recently, similar units operate in Greece also. The Diagnostic Manual of Mental Disorders of the American Psychiatric Association in its latest edition in 2013 (DSM-5), introduced the category "Attenuated Psychosis Syndrome" (APS) for people with early psychotic experiences in the section: "Conditions for further study '...

OBJECTIVE: One reason for worldwide interest in the clinical high-risk (CHR) state for psychosis is its potential as a target for prevention. However, the feasibility and utility of early intervention initiatives that are focused on this stage involve an untested assumption: that most patients with a first episode of psychosis (FEP) experience earlier CHR symptoms. The objective of this study was to identify and characterize the proportion of FEP patients who had experienced such symptoms prior to the onset of their psychosis...

Developmental Aspects in the Early Detection and Intervention in Clinical High Risk States for Psychosis The early detection and intervention in psychoses, which are a main source of disability-adjusted life years already in children and adolescents, have made good progress within the past years. In particular the attenuated and transient positive symptoms of the ultra-high risk criteria and the basic symptom criterion "Cognitive Disturbances" open promising routes to an indicated prevention and have recently been considered as diagnostic criteria of a psychosis-risk syndrome by the European Psychiatric Association (EPA)...

Higher frequencies of perceptual and lesser clinical significance of non-perceptual attenuated psychotic symptoms (APS) have been reported by 8- to 15-year-old of the general population compared to 16- to 40-year-old. We examined if such an age-effect can also be detected in a clinical never-psychotic sample (N = 133) referred to a specialized service for clinical suspicion of developing psychosis. APS and brief intermittent psychotic symptoms (BIPS) were assessed using items P1-P3 and P5 (non-perceptual), and P4 (perceptual) of the Structured Interview for Psychosis-Risk Syndromes, current axis-I disorders with the Mini-International Neuropsychiatric Interview, and psychosocial functioning with the Social and Occupational Functioning Assessment Scale...

In children and adolescents, psychotic disorders already represent one of the leading causes of disability-adjusted life years. During the past two decades, early detection of risk for psychosis has been intensively investigated, and in particular, predictive power for early signs of risk has been initiated and translated into clinical practice. In particular, the attenuated and transient positive symptoms of the ultra-high risk criteria, and the basic symptom criterion "cognitive disturbances", open promising routes to an indicated prevention and have recently been considered by the European Psychiatric Association (EPA) as diagnostic criteria of a psychosis-risk syndrome...

There is limited research on clinical features related to age of presentation of the Attenuated Psychosis Syndrome in children and adolescents (CAD). Based on findings in CAD with psychosis, we hypothesized that an older age at presentation of Attenuated Psychosis Syndrome would be associated with less severe symptoms and better psychosocial functioning than presentation in childhood or younger adolescence. Ninety-four CAD (age 9-18) meeting Attenuated Psychosis Syndrome criteria participated in the study. The sample was divided and compared according to the age of presentation of Attenuated Psychosis Syndrome (9-14 vs 15-18 years)...
