Alzheimer’s Study Identifies 16 Risk Genes

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 whom were from underrepresented populations, to improve understanding of genetic risk factors.

Placental Cells Indicate Fetal Brain Health

Fetal placental macrophages can serve as indicators of fetal brain microglia health, which are crucial for brain development. Immune activation in pregnant women, such as from infections or obesity, can negatively affect fetal brain development. The study used mouse models and found that male fetuses are more affected by maternal obesity than females. This research opens avenues for early identification and intervention in neurodevelopmental disorders.

Vascular Risk Interacts with Amyloid Levels to Increase Age Related Cognitive Decline

Vascular risk factors appear to have a negative synergistic effect with amyloid beta levels in the brain, researchers report. The study suggests a combination of increased vascular risk and higher amyloid levels in the brain can predict more rapid cognitive decline during aging.

Effects of Alcoholism on Brain’s Reward System May Be Different in Women Than Men

Researchers report the reward system in the brains of female alcoholics are larger than in women who are not addicted to alcohol. By contrast, this area is smaller in alcoholic men than non-alcoholic men.

Anesthetic May Affect Tau Spread in the Brain to Promote Alzheimer’s Disease Pathology

Sevoflurane, an anesthetic, causes tau to leave neurons and enter microglia. This stimulates the production of interleukin-6, leading to inflammation and cognitive impairment.
