Memory (M) impairments have been suggested in pediatric Obstructive Sleep Apnea along with attention and executive (AE), language (L), and visuospatial (V) dysfunctions. NEPSY assessment of children aged 5-9 years who were either healthy (N = 43), or who had OSA without L, V, AE (OSA(-), N = 22) or with L (N = 6), V (N = 1), AE (N = 3) (OSA(+), N = 10) dysfunctions revealed no gross memory problems in OSA; however, over the three learning trials of cross-modal association learning of name with face, the OSA(-) progressively improved performance, whereas the OSA(+) failed to progress. No within-group differences between immediate and delayed memory tasks were apparent. The data suggest the presence of slower information processing, and/or secondary memory problems, in the absence of retrieval or recall impairments among a subset of children with OSA. We hypothesize that inefficient/insufficient encoding may account for the primary deficit.

Loss-of-function mutations in PARK7, encoding for DJ-1, can lead to early onset Parkinson's disease (PD). In mice, Park7 deletion leads to dopaminergic deficits during aging, and increased sensitivity to oxidative stress. However, the severity of the reported phenotypes varies.

Aneurysmal Subarachnoid Hemorrhage (aSAH), resulting from ruptured aneurysms, is a major contributor to stroke-related mortality and morbidity. Despite advances in healthcare, aSAH remains severe and often leads to complications such as cerebral vasospasm (CV), cerebral infarction, and delayed ischemic neurological deficits (DIND). Clazosentan, an endothelin receptor antagonist, has demonstrated potential in alleviating vasospasm and its associated outcomes, although evidence of its efficacy remains unclear.

Genetic evidence of the causal relationships between psychiatric disorders and cardiovascular diseases.

Electronic address:

Objective: Our primary objective is to investigate the causal relationships between 12 psychiatric disorders (PDs) and atrial fibrillation (AF), coronary artery disease (CAD), myocardial infarction (MI), and heart failure (HF).

Methods: Firstly, we used linkage disequilibrium score regression to calculate the genetic correlations between 12 PDs and 4 cardiovascular diseases (CVDs). Subsequently, we performed two-sample and bidirectional Mendelian randomization (MR) analyses of phenotypes with significant genetic correlations to explore the causal relationships between PDs and CVDs.

Importance: Current evidence of the association between prenatal exposure to glucocorticoids and long-term mental disorders is scarce and has limitations.

Objective: To investigate the association between prenatal exposure to systemic glucocorticoids and mental disorders in offspring at the age of 15 years, comparing exposed vs unexposed offspring born to mothers with the same underlying disease (risk of preterm delivery and autoimmune or inflammatory disorders).

Design, Setting, And Participants: This nationwide population-based cohort study used data from registries in Denmark with follow-up until December 31, 2018.

Background: Brain iron dyshomeostasis has been observed in behavioral deficits relevant to neurodegenerative diseases such as Alzheimer's disease (AD), but it remains unclear whether it is a primary cause or an epiphenomenon of disease.

Method: We assessed the effects of brain iron dyshomeostasis on spatial cognition and cognitive flexibility using the IntelliCage system, recognition memory using novel object recognition tasks and anxiety-like behavior using the open field and elevated plus maze tests. We investigated these phenotypes in a HfexTfr2 mouse model of brain iron dyshomeostasis alone (Iron) or combined with an APP/PS1 model of Alzheimer's Aβ amyloidosis (Aβ+Iron), compared with APP/PS1 mice with Aβ amyloidosis alone (Aβ) or wildtype controls.
