Schizophrenia Risk May Begin in the Placenta
Summary: A new study highlights the placenta’s role in neuropsychiatric development, showing that DNA methylation influences gene expression tied to psychiatric disorders. Researchers found strong links between placental DNA methylation…
Genetic Variant in ITSN1 Linked to Higher Parkinson’s and ASD Risk
Summary: A new study has identified genetic variants in the ITSN1 gene that significantly increase the risk of developing Parkinson’s disease. Researchers analyzed nearly 500,000 genetic profiles and found that…
Alzheimer’s Study Identifies 16 Risk Genes
Summary: A large whole-genome sequencing study has uncovered 16 new genes linked to Alzheimer’s disease, expanding genetic research beyond European ancestry. Researchers analyzed data from 49,149 individuals, nearly half of…
Genetic Mutation Linked to Schizophrenia Alters Brain Function
Summary: Researchers identified a rare genetic mutation in two schizophrenia patients that increased schizophrenia-related behaviors in mice. The mutation led to higher levels of glycine decarboxylase (GLDC), an enzyme that…
Prenatal Stress Hormones Alter Brain Development
Summary: Environmental factors like stress and medication exposure during pregnancy can shape brain development, but the mechanisms remain unclear. Researchers used brain organoids to study the effects of synthetic glucocorticoids,…
Genetics, Not Maternal Sickness, Drives Autism Risk
Summary: A large study analyzing over 1.1 million pregnancies found no strong evidence that maternal health conditions during pregnancy cause autism. Instead, nearly all previously reported associations between maternal diagnoses…
Delayed Brain Maturation Links Genetics and Eating Disorders
Summary: Over half of 23-year-olds display restrictive, emotional, or uncontrolled eating behaviors, with delayed brain maturation playing a significant role. The research linked structural brain differences, mental health challenges, and…
The Genetic Impact of Forever Chemicals on Brain Function
Summary: Researchers have found that per- and polyfluorinated alkyl substances (PFAS) alter the expression of specific genes in brain-like cells, potentially contributing to neurotoxicity. Among six tested compounds, perfluorooctanoic acid…
