Neurotrophins and neuroinflammation in fetuses exposed to maternal depression and anxiety disorders during pregnancy: a comparative study on cord blood.

In recent years, there have been changes in the approach to maternal psychiatric disorders and their effects on the fetus, with the focus redirected to the search for biological markers. Neurotrophic factors and inflammatory processes have received particular attention in the past few years. According to the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV), the study sample (n = 136) consisted of three groups: mothers with major depressive disorder (MDD group, n = 25), mothers with anxiety disorder (AD group, n = 18), and mothers without any psychiatric disorders (not diagnosed (ND) group, n = 93).

Individuals who differ markedly by sleep chronotype, i.e., morning-type or evening-type also differ on a number of psychological, behavioral, and biological variables.

Impact of enriched environment on production of tau, amyloid precursor protein and, amyloid-β peptide in high-fat and high-sucrose-fed rats.

Objective: The Western-type diet is associated with an elevated risk of Alzheimer's disease and other milder forms of cognitive impairment.

Methods: In total, 40 adult male rats were categorised into two main groups according to their housing conditions: enriched environment (EE, n=16) and standard housing condition (n=24).
