“Patricia Lemer understands the profound role of vision and vision development on a child’s behavior and success, and how visual considerations are often masked or overlooked. She is an authentic soldier in this epidemic scourge of childhood disorders, and at her core, she is a great advocate for kids’ health!”

—Hans F. Lessmann, OD, developmental optometrist at Vision Development Institute

“Patricia Lemer’s new book crucially expands on the concept of ‘total load theory.’ It represents the culmination of Patty’s long and impressive career in counseling and advocacy for children who are labeled but not well understood. She makes very useful distinctions between genetics and environmental load factors as stressors and as opposed to societal load factors. Whereas the former includes susceptibility to toxic elements in food and in the air, the latter features stressors that can provide an unbearable load in the physical, educational, language, and emotional domains. This book is a wonderful addition to the library of any parent or professional looking to reduce load factors from prior conception and throughout the lifespan.”

She outlines the ways to identify vision difficulties and gives the resources to help, including the appropriate vision evaluation and treatment using the optometric power tools of lenses, prisms, colored light filters, and vision therapy.”

—Randy Schulman, MS, OD, FCOVD

From Parents

“Total Load Theory reveals a profound truth: It’s not just one factor that overwhelms a child, but the cumulative burden of many stressors, that creates what Patricia Spear Lemer calls the ‘Total Load.’ In this groundbreaking book, Lemer brings clarity, compassion, and decades of expertise to one of today’s most urgent challenges: understanding and supporting children with autism and other complex neurological conditions. Rather than viewing autism as a fixed label, she reframes it as the body and brain’s response to an overload of stressors—an insight that opens new pathways to healing. Drawing on her extensive clinical experience, Lemer provides a roadmap for identifying root causes and relieving the total load. Her approaches empower parents and practitioners to move beyond symptom management toward integrative strategies that foster resilience and recovery. More than just a theory, Total Load Theory is a beacon of hope. With warmth, wisdom, and an unwavering belief in every child’s potential, Lemer shows families that healing is not only possible—it’s within reach.”

—Judy Ryder Duffy, founder of the “Power Moms: Autism” Facebook groups

Now, adding to her literary accomplishments comes Total Load Theory targeting a broader audience with the latest steps for maximizing function. She did ALL the legwork so you can focus on parenting. This is the only book you need to read. Period.”

—Filomena LaForgia, founder of Filanthropists.com

“Patty Lemer is beyond a maverick in the autism and special needs communities. Soon after my daughter was born and diagnosed with hypotonia (a useless label), and a neurologist claimed she would never speak, I attended a talk featuring Patty. She blew my mind and changed the course of my daughter’s life and mine. Today, Isabella never stops talking and leads a fulfilling life at a gluten-free cafe, pottery studio and an equestrian. Patty also impacted the direction of my career, guiding me as registered dietitian nutritionist to return to my passion about the impact of food on mood.”

—Laura Lagano, functional nutritionist
