Assessment for Autism, ADHD & Related Conditions
Find Answers.
Understand the Whole Picture.
Many adults spend years wondering why certain parts of life seem harder for them than they do for others. You may have wondered about autism or ADHD, received diagnoses like anxiety or depression, or found that previous explanations never quite captured the full picture.
At Higgins Center for Healing, our Comprehensive Neurodiversity Assessment is an in-depth clinical evaluation designed to assess for autism, ADHD, and commonly overlapping conditions, including trauma-related symptoms, OCD, anxiety, and depression. Rather than evaluating one diagnosis in isolation, we look at the full picture—your developmental history, current experiences, patterns of masking, sensory differences, executive functioning, relationships, and more.
The goal isn't simply to give you another label. It's to help you understand what is actually driving your experiences and why. Whether you're seeking answers for the first time or questioning a previous diagnosis, you'll leave the assessment with greater clarity, an individualized understanding of your neurotype and mental health, and recommendations for moving forward.

What Makes Our Assessment Different?
Many evaluations focus on determining whether someone meets criteria for a single diagnosis. Our approach recognizes that neurodevelopmental conditions and trauma frequently overlap, and that their similarities can make diagnosis more complex—especially in adults who have spent years masking their struggles.
We carefully evaluate how different factors may be interacting, including:
- Autism Spectrum Disorder (with expertise in high-masking adults)
- ADHD
- PTSD and Complex PTSD
- Anxiety Disorders
- OCD
- Sensory processing differences
- Executive functioning challenges
- Emotional regulation
- Social communication differences
- Masking and camouflaging behaviors
- Burnout and chronic overwhelm
Our goal is to understand not only what diagnoses may fit, but why they fit—and how your unique history has shaped the way symptoms present today.

Who Is This Assessment For?
This assessment may be a good fit if you:
- Have always felt "different" but never understood why.
- Suspect you may be autistic, have ADHD, or both.
- Have been diagnosed with anxiety or depression but feel there is more to the story.
- Wonder whether trauma has complicated the diagnostic picture.
- Have learned to mask your struggles and worry they have been overlooked.
- Are seeking clarity to guide treatment, accommodations, relationships, or personal understanding.
We have particular experience working with high-masking adults, including individuals who have spent years compensating, people who have been historically overlooked, and those whose strengths may have hidden their challenges.

Receiving a diagnosis is not about putting yourself in a box—it's about gaining language for experiences that may have never made sense before.
