It Could Be Your Eyes

What Are Primitive Reflexes and How Do They Impact Vision and ADHD?

Dr. Juanita Collier, MS, OD, FCOVD Season 2 Episode 22

“Movement drives brain development, and very rarely do you see movement when there is a screen involved.”

Primitive reflexes play a critical role in child development, but what happens when they don’t integrate as expected? In this episode, we’re joined by pediatric occupational therapist and ADHD specialist Jenna Downs from Stronger Roots Therapy. Together, we explore how these early reflexes shape motor, sensory, and visual development—and how their persistence can mimic or worsen symptoms often linked to ADHD, learning difficulties, and vision challenges.

From crawling and handwriting struggles to posture, screen time, and the impact of retained reflexes on focus and reading, Jenna breaks down what parents and educators should know. Most importantly, she shares practical strategies and hope for families navigating these concerns, highlighting the power of neuroplasticity and early interventions.

If you’ve ever wondered whether your child’s fidgeting, difficulty concentrating, or visual struggles might have deeper developmental roots, this conversation will open your eyes to new possibilities for growth and support.
