About
The Chesapeake Advanced ADHD Training Institute
CHAATI emerges from the visionary mind of Dr. Kathleen Nadeau, a world-renowned ADHD expert. As the author of 15 influential books and the founder of The Chesapeake Center – the largest private ADHD specialty clinic in the United States – Dr. Nadeau brings unparalleled expertise to this innovative platform.
CHAATI aims to fill critical gaps in traditional mental health education, offering insights that are often overlooked in standard curricula. It explores the stark differences in how ADHD manifests and impacts females versus males, delves deep into the complex, real-world symptoms that extend far beyond the typical triad of hyperactivity, impulsivity, and inattention, and helps understand how ADHD permeates every aspect of an individual's life, creating unique challenges and opportunities for each person.
By bridging these knowledge gaps, CHAATI empowers mental health professionals to provide more nuanced, effective care for individuals with ADHD. This platform represents a significant step forward in transforming ADHD education and treatment, offering a unique opportunity for professionals to deepen their understanding and improve their practice in this complex field.
