Acta Neuropsychiatr . 2025 Jan; 37():e4. PMID: 39844366
Objective: Accelerated ageing indexed by telomere attrition is suggested in schizophrenia spectrum- (SCZ) and bipolar disorders (BD). While inflammation may promote telomere shortening, few studies have investigated the association between...

Sci Rep . 2024 Oct; 14(1):22755. PMID: 39353988
The caudate nucleus is a part of the striatum, and striatal hyperdopaminergia is considered central to the pathophysiology of schizophrenia. How caudate volume is affected in schizophrenia and what role...

Psychol Med . 2024 Apr; 54(10):2369-2379. PMID: 38563302
Background: Dysmyelination could be part of the pathophysiology of schizophrenia spectrum (SCZ) and bipolar disorders (BPD), yet few studies have examined myelination of the cerebral cortex. The ratio of T1-...

Sci Rep . 2024 Mar; 14(1):5327. PMID: 38438515
Toxoplasma gondii (TOXO) infection typically results in chronic latency due to its ability to form cysts in the brain and other organs. Latent toxoplasmosis could promote innate immune responses and...

Schizophr Bull . 2024 Jan; 50(3):533-544. PMID: 38206841
Background: The hypothalamus is central to many hormonal and autonomous nervous system pathways. Emerging evidence indicates that these pathways may be disrupted in schizophrenia and bipolar disorder. Yet, few studies...

Transl Psychiatry . 2024 Jan; 14(1):16. PMID: 38191519
Epigenetic modifications influenced by environmental exposures are molecular sources of phenotypic heterogeneity found in schizophrenia and bipolar disorder and may contribute to shared etiopathogenetic mechanisms of these two disorders. Newborns...
