Abstract Background and Hypothesis Hallucination-like experiences (HLE) are increasingly conceptualized as existing on a continuum ranging from normative perceptual anomalies to clinically significant psychotic symptoms. Although substantial research has examined HLE in nonclinical populations, comparatively limited evidence is available from South Asian contexts, particularly using...

Abstract Background and Hypothesis Affective instability (AffI) is associated with psychosis, and cannabis use is a known risk factor for psychosis. Previous evidence suggests that AffI may itself be a risk factor for cannabis use. This study aimed to investigate the longitudinal relationship between AffI and cannabis use during adolescence and the development of psychosis in early adulthood....

Background and Hypothesis: Paranoia is commonly conceptualized along a continuum ranging from transient suspiciousness and mistrust to fixed persecutory delusions. However, similar paranoid contents may differ in conviction, flexibility, self-reference, distress, functional impact, and embeddedness in broader changes of self, agency, and world-experience. We synthesized qualitative evidence on...

This study proposes to determine whether sleep disruption acts as a mediator of the cannabis-to-psychosis relationship. Study Design This longitudinal study assessed measures of cannabis use...

Predominantly, the ultrahigh-risk population is aged 18-35 years, but it may also include younger children and adolescents. Individuals in this population experience psychosis prodromes in the form of attenuated or brief psychotic symptoms...

Both chronic cannabis use and psychotic disorders are associated with abnormalities in visual attentional processing. Using functional magnetic resonance imaging (fMRI), we sought to determine whether there would be a difference in functional connectivity in patients and controls with and without a history of cannabis use in the visual and dorsal attention networks. Resting-state fMRI data were...
