NIH-funded research R21 grant

Investigating how a pesticide affects brain communication and memory in children

Official title: Brain derived extracellular vesicles-mediated neurotoxicity of deltamethrin

Funded at University of Texas Med Br Galveston · NIH-10679858 · Data updated 2026-11-12

This study is looking at how being exposed to the pesticide deltamethrin early in life might affect brain development and communication between brain cells, which could help us understand why some kids might develop conditions like ADHD.

Who could benefit from this research

Could help

Ideal candidates for this research are children who have been exposed to pyrethroid pesticides and exhibit symptoms of ADHD or other memory-related dysfunctions.

Less likely to help

Patients who have not been exposed to pyrethroid pesticides or do not exhibit neurodevelopmental disorders may not benefit from this research.

What this research studies

This research explores the impact of early-life exposure to the pesticide deltamethrin on brain development, particularly focusing on how it disrupts communication between brain cells through brain-derived extracellular vesicles (BDEVs). The study uses animal models to examine the mechanisms by which deltamethrin exposure may lead to neurodevelopmental disorders like ADHD. By analyzing changes in BDEV biogenesis and their effects on synaptic function, the research aims to uncover the underlying causes of memory deficits associated with this exposure.

Why it matters

Potential benefit: If successful, this research could lead to better understanding and prevention strategies for ADHD and other neurodevelopmental disorders in children.

How similar studies have gone: Previous studies have indicated that early-life exposure to environmental toxins can significantly impact neurodevelopment, suggesting that this research builds on established findings in the field.
