Dynamic Functional Connectivity States Reflecting Psychotic-like Experiences

Scales for rating psychotic and psychotic-like experiences as continua.

Although psychotic symptoms are usually viewed as dichotomous events, both patients and nonpatients often report isolated psychotic experiences as well as psychotic-like experiences, the latter being attenuated versions of psychotic experiences. College students, previously identified as probably at high risk for psychosis, were interviewed using a modified Schedule for Affecting Disorders and ...

Predicting Psychotic-Like Experiences during Sensory Deprivation

AIMS This study aimed to establish the contribution of hallucination proneness, anxiety, suggestibility, and fantasy proneness to psychotic-like experiences (PLEs) reported during brief sensory deprivation. METHOD Twenty-four high and 22 low hallucination-prone participants reported on PLEs occurring during brief sensory deprivation and at baseline. State/trait anxiety, suggestibility, and fa...

Psychotic-like Experiences in Nonclinical Adolescents

Dynamic functional connectivity.

Recent studies show that anatomical and functional brain networks exhibit similar small-world properties. However, the networks that are compared often differ in what the nodes represent (e.g. sensors or brain areas), what kind of connectivity is measured, and what temporal and spatial scales are probed. Here, I review studies of large-scale connectivity and recent results from a variety of rea...

Prevalence and characteristics of psychotic-like experiences in Kenyan youth.

Current evidence suggests that there may be significant differences in psychotic symptom prevalence in Africa compared with other cultures. However, there have been few studies evaluating these symptoms in the continent. We conducted a cross-sectional survey of psychotic-like experiences (PLEs) in 2963 Kenyan students from seven tertiary academic institutions spread across Kenya, using a self-a...
