About the Center for Diagnostic Excellence

The Center for Diagnostic Excellence at Minnesota Mental Health Clinics provides comprehensive ADHD and Autism (ASD) assessments for children, teens, adults seeking first-time or updated diagnosis, and individuals unsure whether their symptoms are ADHD, ASD, both, or related to another condition. Our evaluations are designed to deliver clarity, diagnostic accuracy, and individualized recommendations so you can confidently take the next steps in care. 

Whether you’re seeking a new diagnosis, confirming previous concerns, or exploring attention or developmental differences, our clinicians specialize in neurodevelopmental testing that examines the whole person: cognitive, emotional, behavioral, social, and functional.

What is ADHD?

ADHD affects attention, organization, and impulse control, often causing focus and time‑management challenges but also bringing creativity and energy. With proper support, individuals with ADHD can thrive.

ADHD assessments are available starting at 6 years old.

What is ASD?

ASD affects social communication, sensory processing, and behavior. Individuals may prefer predictability, communicate differently, and experience sensory sensitivities, while also showing strong focus, deep interests, and meaningful strengths. Supportive, personalized environments help promote independence and wellbeing.

ASD assessments are available starting at 2.5 years old.

ADHD evaluations are available starting at age 6. ASD evaluations are available starting at age 2.5. Why does this matter? Based on 2025 CDC data, ASD is identified in 3.2% of 8-year-old children in the the U.S., and about 12% of U.S. children (ages 3-17) have been diagnosed with ADHD, making early, accurate evaluation and support critical.

Absolutely. Clients can transition directly into therapy, psychiatry, skills coaching, or care coordination through our integrated network. 

Our evaluations create a detailed diagnostic profile across cognitive, emotional, behavioral, and social domains.

  • Attention & Focus: Difficulties with sustaining attention, task completion, distractibility, or managing competing demands
  • Emotional Regulation: Coping skills, emotional reactivity, frustration intolerance, and patterns that affect self-esteem or relationships.
  • Executive Functioning: Planning, organization, working memory, decision-making, emotional control, and time management are all core features of ADHD.
  • Hyperactivity & Impulsivity: High energy levels, restlessness, impulsive decision-making, or interrupting behaviors.
  • Social Communication Patterns: Clinicians observe the individual’s real-time social communication through structured or semi-structured activities.
  • Other Behavioral & Cognitive Factors: Screening for co-occurring conditions that may impact symptoms or treatment approaches, such as anxiety or learning disabilities.

Our Diagnostic Process

We provide a thorough, person‑centered evaluation experience that offers clear insight and practical next steps.

Clinical Interview: A detailed discussion about history, strengths, challenges, and goals.

Standardized Testing & Questionnaires: Assessments tailored to your symptoms and developmental stage.

Behavioral & Cognitive Evaluation: We explore attention, executive function, social‑emotional development, and learning patterns to build a full diagnostic picture.

Comprehensive Diagnostic Profile: You receive an in‑depth written report, including:

  • Confirmed diagnosis or ruling out differential diagnoses
  • Strengths & needs summary
  • Evidence‑based recommendations for school, work, or home

Support & Navigation After Diagnosis: We guide individuals and families through next steps—therapy options, school accommodations, workplace supports, and more.

What happens after testing?

Clients can seamlessly transition into MMHC’s broader mental health system:

Therapy & Skills Sessions: Support for emotional regulation, executive functioning, coping skills, and family dynamics.

Psychiatry: Medication support for ADHD, anxiety, or co‑occurring conditions.

Executive Functioning Support: Organizational coaching, study skills, and planning support for diagnosed individuals.

Care Coordination: Collaboration with schools, primary care, employers, and other providers to ensure accommodations are applied effectively.

Integrated Care & Strong Referral Network: After testing, clients have immediate access to MMHC’s full mental health team, including:

  • Individual therapy
  • Psychiatry & medication management
  • Executive functioning & organizational skills support
  • DBT/CBT skills groups
  • Family therapy

Your results transfer seamlessly into a coordinated care plan—no need to start over with a new provider.

After diagnostic testing is complete, our team provides a seamless next step by coordinating an internal referral to ensure clients receive the right therapeutic support. If a client already has a specific clinician in mind, we’re happy to help facilitate that connection and do our best to match them with their preferred provider.
