Wang H, Liu Z, Nakua H, Hegarty C, Thies M, Patel P, et al.
Biol Psychiatry
. 2024 Jun;
97(2):167-177.
PMID: 38908657
Background: Patients with early psychosis (EP) (within 3 years after psychosis onset) show significant variability, which makes predicting outcomes challenging. Currently, little evidence exists for stable relationships between neural microstructural...

28(3):1159-1169.
PMID: 36510004
Emerging evidence suggests brain white matter alterations in adolescents with early-onset psychosis (EOP; age of onset <18 years). However, as neuroimaging methods vary and sample sizes are modest, results remain...

27(2):1241-1247.
PMID: 34789848
Dysregulation of dopamine systems has been considered a foundational driver of pathophysiological processes in schizophrenia, an illness characterized by diverse domains of symptomatology. Prior work observing elevated presynaptic dopamine synthesis...

PMID: 33712377
Background: The rs1344706 single nucleotide polymorphism in the ZNF804A gene has been associated with risk for psychosis in multiple genome-wide association studies, yet mechanisms underlying this association are not known....

. 2021 Jan;
31(6):2834-2844.
PMID: 33429433
Recent efforts to evaluate the heritability of the brain's functional connectome have predominantly focused on static connectivity. However, evaluating connectivity changes across time can provide valuable insight about the inherent...
