Article Synopsis
  • The study investigated brain metabolite differences in the medial prefrontal cortex (mPFC) of individuals with bipolar disorder (BD) during acute and euthymic episodes over a 6-month medication treatment period.
  • Using H-MRS technology, researchers compared metabolite levels in 53 BD patients (32 in depressive phase, 21 in manic phase) and 34 healthy controls at baseline, then followed up with 40 subjects after treatment.
  • Results showed significant reductions in N-acetyl aspartate (NAA) in both depressive and manic episodes compared to healthy controls, and a notable decrease in glutamine (Gln) levels in the manic group after 6 months, suggesting that these metabolites may serve as

Backgrounds: Thyroid function was associated with depression and psychotic symptoms; however, little research has focused on its role in coexisting psychotic symptoms in adolescents with depressive disorder. This study aimed to explore the association between thyroid function and psychotic symptoms among depression adolescents.

Methods: A total of 679 adolescent patients (aged 12-18) diagnosed as depressive disorder were recruited.

Objective: Impaired cognitive function is a central symptom of schizophrenia and is often correlated with inferior global functional outcomes. However, the role of some neurobiological factors such as cortical structure alterations in the underlying cognitive damages in schizophrenia remains unclear. The present study attempted to explore the neurobiomarkers of cognitive function in drug-naive, first-episode schizophrenia by using structural magnetic resonance imaging (MRI).

Background: Many patients with major depressive disorder (MDD) have been found to have psychotic symptoms. However, few studies have reported the prevalence of comorbid psychotic symptoms in first-episode drug naïve (FEDN) MDD patients. This study was to investigate the prevalence of psychotic symptoms and related risk factors in a large sample size of FEDN MDD patients in a Chinese population.

Evidence shows that BDNF may regulate activity-dependent forms of synaptic plasticity underlying learning and memory. Previous studies reported low BDNF levels and cognitive impairment in the early stage of schizophrenia. Our current study aimed to explore the association between serum BDNF and cognitive functions in first-episode drug-naïve (FEDN) patients with schizophrenia, which has been under-investigated.
