Maybe it started with an article someone shared, or a video that described your own life back to you with uncomfortable accuracy. Or maybe it’s your child, and every professional you’ve asked has said something different, while a relative is certain they’ll grow out of it. Either way, the question has been with you for a while, and it keeps coming back.
Wondering takes energy. You’ve probably run through checklists online, felt sure one week and talked yourself out of it the next. A question this persistent deserves a proper answer, and a proper answer comes from a formal assessment.
Dr. Mason is an American psychologist who has practiced in Bangkok since 2012. He carries out autism assessments in English, for adults and children. Autism can be assessed on its own, or together with ADHD.
Why people come for an assessment
Adults often come looking for an explanation: why things that look easy for other people have always taken more out of them, why jobs and friendships keep repeating the same pattern of going well and then going wrong. Parents often come after years of hearing different things from different people, and wanting a straight answer from someone whose job it is to give one.
What an answer gives you is concrete. It’s an explanation that holds still, instead of the improvised ones you’ve been using. It’s something you can show a school or an employer, which matters, because institutions act on reports rather than impressions. And it ends the guessing, which for many people has been the tiring part all along.
It’s worth being honest about what a diagnosis is and isn’t. It’s information, not a fix. It doesn’t change who you are, or who your child is. Some people find the answer a relief; others find it complicated, and some find it’s both at once. None of those is the wrong response. And if the assessment concludes it isn’t autism, that’s a real answer too.
What the assessment involves
This is a formal assessment, in English, carried out by Dr. Mason, a licensed psychologist. It covers personal history and how you or your child function day to day. It ends in a written report, which follows about three days after the final session.
An autism assessment on its own takes two sessions. Where autism is assessed alongside ADHD, it runs over three. An ADHD assessment on its own also takes two. There’s a separate page about ADHD assessment and testing, and one on AuDHD assessment if you’re considering both.
Assessments take place at our Sukhumvit 81 office in Phra Khanong, at The Racquet Club on Sukhumvit 49/9, or online.
