Hypoplastic Nasal Bone Hypoplastic nasal bone refers to the underdevelopment or reduced size of the fetal nasal bone , most commonly identified during prenatal ultrasound examinations in the first or second trimester. It is considered a significant soft marker for chromosomal abnormalities , particularly Down syndrome (Trisomy 21) , and may also be associated with other aneuploidies such as Trisomy 18 and Trisomy 13. While the presence of a hypoplastic nasal bone increases genetic risk, it can also be observed in normal fetuses, with prevalence varying by ethnicity. Therefore, its clinical significance is best interpreted alongside maternal age, biochemical screening, and advanced diagnostic tests such as NIPT, chorionic villus sampling (CVS), or amniocentesis .

Brain Development Psychology Brain Development Psychology is a specialized field of psychology that examines how the human brain grows, matures, and changes across the lifespan, with a strong focus on infancy, childhood, and adolescence. It explores the relationship between neural development and cognitive, emotional, social, and behavioral functioning. This discipline integrates insights from neuroscience , developmental psychology, and cognitive science to understand how genetics, environment, learning, and experience shape brain structure and function. Research in brain development psychology plays a critical role in identifying developmental milestones, understanding neurodevelopmental disorders , and informing educational practices, mental health interventions, and public health policies aimed at promoting healthy brain development .
