A top ADHD and ADD treatment center should provide a comprehensive, evidence-based approach tailored to individual needs. Look for centers that offer a combination of behavioral therapy, medication management, and skills training. Ensure the center is staffed by licensed professionals, including psychiatrists, psychologists, and therapists with expertise in ADHD. Additionally, the facility should provide support for co-occurring conditions like anxiety or learning disabilities, as these are common among individuals with ADHD.
