Background The OAV questionnaire has been developed to integrate research on altered states of consciousness (ASC). It measures three primary and one secondary dimensions ASC that are hypothesized be invariant across induction methods. rating scale in use for more than 20 years applied internationally a broad range fields, yet its factorial structure never tested by structural equation modeling techniques psychometric properties have examined large samples experimentally induced ASC....
Psilocybin and related hallucinogenic compounds are increasingly used in human research. However, due to limited information about potential subjective side effects, the controlled medical use of these has remained controversial. We therefore analysed acute, short- long-term effects psilocybin healthy humans by pooling raw data from eight double-blind placebo-controlled experimental studies conducted between 1999 2008. The analysis included 110 subjects who had received 1–4 oral doses...
Responses to hallucinogenic drugs, such as psilocybin, are believed be critically dependent on the user's personality, current mood state, drug pre-experiences, expectancies, and social environmental variables. However, little is known about order of importance these variables their effect sizes in comparison dose. Hence, this study investigated effects 24 predictor variables, including age, sex, education, personality traits, pre-experience, mental state before intake, experimental setting,...
To date, the MRI-based individualized prediction of psychosis has only been demonstrated in single-site studies. It remains unclear if MRI biomarkers generalize across different centers and MR scanners represent accurate surrogates risk for developing this devastating illness. Therefore, we assessed whether a system identified patients with later disease transition among 73 clinically defined high-risk persons recruited at two early recognition centers. Prognostic performance was measured...
Adverse childhood experiences (ACEs) are common in people at clinical high-risk for psychosis (CHR), however, the relationship between ACEs and long-term outcomes is still unclear. This study examined associations CHR individuals. 344 individuals 67 healthy controls (HC) were assessed using Childhood Trauma Questionnaire (CTQ), Bullying Experience of Care Abuse (CECA). followed up to 5 years. Remission from state, transition (both defined with Comprehensive Assessment an At Risk Mental...
Converging evidence indicates that neural oscillations coordinate activity across brain areas, a process which is seemingly perturbed in schizophrenia. In particular, beta (13-30 Hz) and gamma (30-50 were repeatedly found to be disturbed schizophrenia linked clinical symptoms. However, it remains unknown whether abnormalities current source density (CSD) lagged phase synchronization of distributed regions the already occur patients with an at-risk mental state (ARMS) for psychosis.To further...
BackgroundA key clinical challenge in the management of individuals at high risk for psychosis (CHR) is that it difficult to predict their future outcomes. Here, we investigated if levels circulating molecular lipids are related adverse outcomes this group.MethodsSerum lipidomic analysis was performed 263 CHR and 51 healthy control subjects, who were then clinically monitored up 5 years. Machine learning used identify lipid profiles discriminated between subgroups subjects with distinct...
Background: The at-risk mental state for psychosis (ARMS) and the first episode of have been associated with structural brain abnormalities that could aid in individualized early recognition psychosis. However, it is unknown whether development these alterations predates clinical deterioration individuals, or alternatively, parallels transition to at single-subject level. Methods: We evaluated performance an magnetic resonance imaging (MRI)-based classification system classifying disease...
Objectives: Brain-derived neurotrophic factor (BDNF) is involved in numerous cognitive processes. Since deficits are a core feature of psychotic disorders, the investigation BDNF levels psychosis and their correlation with cognition has received increased attention. However, there no studies investigating individuals an at-risk mental state (ARMS) for psychosis. Hence, aims present study were: (1) assessing peripheral across different (potential) stages psychosis; (2) association...
Background: 3,4-methylenedioxymethamphetamine (MDMA, “ecstasy”) is used both recreationally and therapeutically. Little known about the factors influencing inter- intra-individual differences in acute response to MDMA. Effects of other psychoactive substances have been shown be critically influenced by personality traits mood state before intake. Methods: We pooled data from 10 randomized, double-blind, placebo-controlled, cross-over studies performed same laboratory 194 healthy subjects...
<h3>Importance</h3> The behavioral and cognitive symptoms of severe psychotic disorders overlap with those seen in dementia. However, shared brain alterations remain disputed, their relevance for patients at-risk disease stages has not been explored so far. <h3>Objective</h3> To use machine learning to compare the expression structural magnetic resonance imaging (MRI) patterns behavioral-variant frontotemporal dementia (bvFTD), Alzheimer (AD), schizophrenia; estimate predictability bvFTD...
Abstract Background: Several sex differences in schizophrenia have been reported including cognitive functioning. Studies with patients and healthy controls (HC) indicate that the advantage for women verbal domains is also present patients. However, findings inconsistent. No study focused on sex-related performance at-risk mental state psychosis (ARMS) individuals yet. Thus, aim of was to investigate functioning ARMS, first episode (FEP) HC subjects. We expected a better learning memory all...
