Abstract Background Delays in seeking help are common in schizophrenia and are associated with negative outcomes. In addition to structural barriers, there is growing evidence that subjective interpretations of psychotic experiences, including delusions, voices, and religious or spiritual attributions, play a crucial role in recognizing symptoms and seeking care. Objective This study explores...

This study investigates changes in stress parameters in individuals with schizophrenia spectrum disorders participating in mindfulness-based group therapy (MBGT). N = 45 participants were randomised to MBGT or Treatment as Usual over four weeks. Before and after each session, psychological and biological stress markers by self-rating scales and cortisol saliva samples were assessed in the...

Felt presence (FP) - sensing another person without clear sensory evidence - has been described in psychosis for over a century but rarely studied due to challenges in recognition and assessment. Recently FP has been identified as a transdiagnostic phenomenon and highlighted by people with lived experience of psychosis as a clinical priority. Here we describe FP presentation in a first-episode...

While voice-hearing in psychosis has received much attention, perceptual experiences in other sensory modalities and psychiatric conditions have remained relatively overlooked. The present review aimed to address this gap by providing an overview of voices/altered perceptual experiences (APE) across psychotic, mood and anxiety disorders in terms of phenomenological characteristics,...

Adolescence and early adulthood are characterized by the development of cognitive and social skills necessary for autonomous functioning in adult roles. As classically described by Erik Erikson, this developmental process involves forging a meaningful sense of identity, comprising a worldview, set of moral values, and occupational aspirations. This may require individuals questioning or defying...

Ganzfeld conditions induce alterations in brain function and pseudo-hallucinatory experiences, particularly in people with high positive schizotypy. The current study uses graph-based parameters to investigate and classify brain networks under Ganzfeld conditions as a function of positive schizotypy. Participants from the general population (14 high schizotypy (HS), 29 low schizotypy (LS)) had...

Virtual reality (VR) technology can be a supporting tool to enhance mindfulness. Recently, many research using VR-based mindfulness (VBM) has been carried out in various psychiatric disorders but not in psychosis. We investigated safety and effects of virtual reality-based mindfulness (VBM) in patients with psychosis as a pilot study. Sixty-four patients were randomly assigned to VBM or to VR...

Head-twitch response (HTR) allows for the detection and classification of behavior associated with serotonin 2A receptor (5-HT_2AR) activation upon psychedelic administration in rodent models. This activation and functional output can be utilized to provide insights into molecular mechanisms associated with psychosis and to identify signaling processes related to existing and novel...

Formal thought disorder (FTD) is a multidimensional syndrome mainly occurring along the psychosis continuum. Cannabis use is known to increase symptoms of psychosis, particularly positive symptoms. However, the impact of cannabis use on FTD in individuals presenting symptoms along the psychosis continuum remains unclear. To address this knowledge gap, we conducted a meta-analysis examining the...

Although epidemiological studies report that hallucinations occur in 6-15% of the general population, little is known about their phenomenology. To overcome this paucity, this study investigates the phenomenological characteristics of hallucinations in the general population, by using a nationally promoted online survey to assess hallucination phenomenology in four sensory modalities, through a...

Abstract It is unclear whether early psychosis in the context of cannabis use is different from psychosis without cannabis. We investigated this issue by examining whether abnormalities in oculomotor control differ between patients with psychosis with and without a history of cannabis use. We studied four groups: patients in the early phase of psychosis with a history of cannabis use (EPC; n =...

Abstract Sleep disruption is commonly associated with psychotic experiences. While sparse, the literature to date highlights nightmares and related distress as prominent risk factors for psychosis in students. We aimed to further explore the relationship between specific nightmare symptoms and psychotic experiences in university students while examining the mediating role of emotion...
