How to Prepare for an Autism Diagnosis?IN BRIEF
Meeting with a specialist to better understand our neurological differences can feel stressful. To ensure the best outcomes, it’s essential to be honest and not hide any challenges. It’s normal for people to become emotional during this process, as it often brings up difficult memories—there’s no need to feel bad about this. During the diagnostic appointment, it’s crucial to bring documentation and observations from other professionals. You can also include relevant reports from teachers or employers that relate to your challenges. To better prepare a list of your unique traits, try recalling comments made by those close to you. Involving family or friends can help you review the extensive checklist provided here.

Preparing for a Diagnostic Appointment as a Teen or Adult
The process of obtaining a diagnosis can feel overwhelming. Many people have waited a long time for this step, hoping for clarity and answers. Being well-prepared is key.
Mental Preparation
Multiple Diagnoses
Autism often does not occur in isolation. It is common for individuals to receive multiple diagnoses, some of which might be unexpected.
Ruling Out Misdiagnoses
Sometimes, people suspect they are autistic because their experiences resemble those associated with autism. However, receiving an accurate diagnosis is more important than avoiding mistakes.
Emotional Vulnerability
Discussing challenges and recalling obstacles from the past can be difficult. This process may feel focused on the less pleasant aspects of life. It’s an essential step, and honesty is crucial. The professional is not there to judge you; they need accurate information to provide a reliable diagnosis.
Masking
Many teens and adults have learned to mask their differences to appear “typical.” If possible, try to stop masking during the evaluation. If this isn’t feasible, explaining what you do to mask can help the professional understand your experiences.
Document Preparation
Gather relevant documents that provide insight into your challenges:
- Medical documentation and a list of any known diagnoses.
- Reports or evaluations from other professionals (psychologists, physicians, social workers, etc.).
- Notes or feedback received at work or during your education.
Compiling a List of Differences
People often overlook the full extent of their unique traits or behaviors. Reviewing this list with close family members or those who knew you during childhood can be helpful.
