Bahij Khouzami: Beyond Behavior

Toxins and Tiny Brains: What BTEX Exposure Tells Us About Autism Risk

Hosted by: Bahij Khouzami, M.Ed., BCBA, IBA Beyond Behavior Podcast Episode 1: In this episode, I explore a compelling study from China that links prenatal exposure to BTEX compounds—benzene, toluene, ethylbenzene, and xylene—with increased autism risk in young children. You’ll learn what BTEX is, how exposure occurs, and how these toxins may affect the developing brain. More importantly, you'll hear practical strategies from an ABA perspective for early screening, goal-setting, and supporting families through prevention and education. 🧪 Topics Covered: * What are BTEX compounds and where do we find them? * Study design and key findings linking BTEX exposure to autism risk * How VOCs can affect fetal brain development * Behavioral red flags and early signs of ASD * How BCBAs can incorporate environmental history into assessments * Practical tips for families to reduce BTEX exposure * Why early intervention and education matter * Prenatal exposure to BTEX may double autism risk * VOCs can affect neurological and hormonal development in utero * ABA professionals should consider environmental factors during intake * Families can reduce risk by using low-VOC products and improving indoor air quality 🧠 Key Takeaways: * Prenatal exposure to BTEX may double autism risk * VOCs can affect neurological and hormonal development in utero * ABA professionals should consider environmental factors during intake * Families can reduce risk by using low-VOC products and improving indoor air quality Original Study: ⁠Prenatal exposure to benzene, toluene, ethylbenzene, and xylene (BTEX) and the risk of autism spectrum disorders in children aged 16–37 months: A prospective cohort study⁠ [https://www.sciencedirect.com/science/article/abs/pii/S0269749125010735] 🎧 Listen & Subscribe: Available on Spotify, Apple Podcasts.

Episode 1: Can Vitamin D3 Improve Autism Symptoms? A New Study Breaks It Down

In this FIRST episode of Beyond Behavior, we explore a new clinical study on vitamin D3 nanoemulsion and its impact on children with autism. Learn how this advanced supplement improved language, social skills, and adaptive behavior—plus why bioavailability matters more than dosage. 🧠 This summary is based on AI-generated insights from peer-reviewed research. 📖 Read the full study here: https://doi.org/10.1016/j.lmd.2025.100071 [https://doi.org/10.1016/j.lmd.2025.100071]
