Clinical and cognitive outcomes in first-episode psychosis: focus on the interplay between cannabis use and genetic variability in endocannabinoid receptors

Frontiers in Psychology August 12, 2024 Maitane Oscoz-Irurozqui, Maria Guardiola-Ripoll, Carmen Almodóvar-Payá et al.

Introduction Research data show the impact of the endocannabinoid system on psychosis through its neurotransmission homeostatic functions. However, the effect of the endocannabinoid system genetic variability on the relationship between cannabis use and psychosis has been unexplored, even less in first-episode patients. Here, through a case-only design, we investigated the effect of cannabis...

First-episode psychosis is characterized by failure of deactivation but not by hypo- or hyperfrontality.

Psychological Medicine January 2012 Amalia Guerrero‐Pedraza, Peter J. McKenna, Jesús J. Gomar et al.

It is not known whether first-episode psychosis is characterized by the same prefrontal cortex functional imaging abnormalities as chronic schizophrenia. Thirty patients with a first episode of non-affective functional psychosis and 28 healthy controls underwent functional magnetic resonance imaging (fMRI) during performance of the n-back working memory task. Voxel-based analyses of brain...

Failure to deactivate in the prefrontal cortex in schizophrenia: dysfunction of the default mode network?

Psychological Medicine August 1, 2008 Edith Pomarol‐Clotet, R. Salvador, Salvador Sarró et al.

Background: Functional imaging studies using working memory tasks have documented both prefrontal cortex (PFC) hypo- and hyperactivation in schizophrenia. However, these studies have often failed to consider the potential role of task-related deactivation. Method: Thirty-two patients with chronic schizophrenia and 32 age- and sex-matched normal controls underwent functional magnetic resonance...
