Diagnosis
for Adults

It’s not uncommon for someone to receive a diagnosis of Autism in adulthood.

Not as much was known about Autism over 30 years ago.  While diagnostic testing has improved for younger children, our medical community still struggles to identify adults with Autism.

Because Autism characteristics are becoming more known to the general population, more undiagnosed adults are recognizing that Autism may explain their significant life-long experiences and struggles.

The Autism Society Inland Empire has compiled this toolkit to answer some of the common questions we receive.  Click on the graphic for the pdf version, available free to download.  We also have a confidential support group for adults diagnosed later in life or seeking a diagnosis that usually meets once a month.  Check our calendar for the next meeting date.

Autistic adults may have differences in social, emotional, and communication skills that vary from the general population. Many people with Autism also have different ways of learning, paying attention, or reacting to things. Indications of Autism may begin during early childhood and typically last throughout a person’s life.

Common indications of Autism in adults may include:

  • becoming anxious about social situations
  • finding it hard to make friends or preferring to be on your own
  • seeming blunt, rude, or not interested in others
  • finding it hard to say how you feel
  • taking things very literally
  • having the same routine every day and getting very anxious if it changes
  • not understanding social “rules.”
  • avoiding eye contact or using cognitive effort in meeting society’s expectation of eye contact
  • getting too close to other people, or getting very upset if someone touches or gets too close to you
  • noticing small details, patterns, smells, or sounds that others do not
  • displaying hyperfocus in certain subjects or activities

It is common for us to receive calls from adults who are just discovering they may have Autism. You can be diagnosed at any age.

Currently, there are no medical tests that can diagnose autism.

A neurologist or a psychologist can perform an Autism assessment diagnosis. Your insurance company can direct you if you have insurance.

Autism Society Inland Empire has a variety of events, workshops and a monthly support group just for adults who think they may be on the spectrum or diagnosed later in life. Visit the calendar for the dates.

choices, rights, responsibilities, and chances to speak up to empower themselves as everyone else.

On-Line Autism Tests

There are also several free online tests you can take that may indicate whether you are on the Autism spectrum or not. Please note that these online tests do not take the place of a professional diagnosis and only indicate that you may be on the Autism spectrum.

RDOS—Aspie-Quiz:
https://rdos.net/eng/Aspie-quiz.php
According to the websitehttps://rdos.net/eng/Aspie-quiz.php, this test aims to check for broader Autism cluster
(Aspie) and neurotypical traits in adults. Broader Autism clusters traits can
give a reliable indication of Autism spectrum traits before an eventual
diagnosis.

The Ultimate Autism Resource:
https://embrace-autism.com/
Provides additional Autism tests and assessments worth taking a look at.

The Ritvo Autism Asperger Diagnostic Scale-Revised (RAADS-R):
https://www.aspietests.org/raads/
According to the website, The RAADS-R is a modified version of the Ritvo
Autism Asperger’s Diagnostic Scale (Ritvo et al. 2008). The rationale for its
development was the need for a clinical adjunct diagnostic tool. While
several diagnostic scales for children and adolescents with ASD are
available, only one peer-reviewed scale, The Autism-Spectrum Quotient
(AQ) was designed specifically for adults. Its authors emphasize that it is
useful in identifying Autistic traits and as a screening instrument but not
as a diagnostic tool.
