How is Autism Diagnosed at Medens Health?

The diagnosis of autism in adults can be complex and generally is based on a comprehensive evaluation by a trained professional, such as a psychologist or psychiatrist.

In children, an early diagnosis allows for early intervention, ensuring that a child will start receiving the help they need to build their skills. In adults, a diagnosis of ASD can bring clarity and hope after a lifetime of confusion and frustration. When ASD remains undetected, it regularly leads to secondary problems (e.g., depression, anxiety, and burn-out), and can reduce a quality of life.

The diagnostic process typically involves taking a detailed history of the individual’s development, observing their behavior and signs, and conducting tests that assess speech, language, cognitive and social skills. If a diagnosis is suspected, additional information such as family history, medical records, and tests that measure sensory processing can be used to understand the individual’s condition better.

Signs of autism in adults


It is possible for ASD to be misdiagnosed in childhood and for a person to reach adulthood without ever being diagnosed. Often ASD is concealed by co-morbid psychopathology (diagnostic overshadowing), and greater subtlety in the manifestations of ASD. Above-average intelligence, an optimal environment, and acquired camouflaging behaviors also make it difficult to recognize the symptoms of ASD in adults.  

Since Autism is a spectrum disorder, individuals with ASD may exhibit a few, many, or all these signs:


Even if an adult has been “getting along” with undiagnosed ASD their whole life, a diagnosis can provide a sense of relief, an explanation for years of frustration, and a path forward to a more manageable life. Once the diagnosis is made, a treatment plan should be created that is tailored to meet the individual’s needs and preferences. If you suspect that you or someone you love may have ASD, speak to your doctor or have them speak to theirs. You can also contact Medens Health to explore getting assessed for ASD. 

Diagnosing Autism Spectrum Disorder with ADOS-2


Various ASD questionnaires for adults are used in clinical practice, including theAutism-spectrum Quotient, the Ritvo Autism Asperger Diagnostic Scale-Revised, the Social Responsiveness Scale Adult Version, and the Social Communication Questionnaire. In addition to multiple questionaries, we integrate ADOS-2 (Autism Diagnostic Observation Schedule) and ADI-R (Autism Diagnostic Interview-Revised) into our evaluation process. The ADOS-2 is a semi-structured observation of the patient and includes five modules used for the evaluation of individuals with different developmental and language levels. ADI-R is a structured interview procedure used to assess the full range of social and language development. Both instruments are extensively used to assess the presence of ASD in children, adolescents, and adults.

Additional evaluation for ASD & other conditions


At Medens Health, theADOS-2 and ADI-R are not used alone to determine a diagnosis of ASD. Instead, we perform a comprehensive evaluation to obtain a full picture of the patient’s life. We may evaluate their developmental history, information provided by parents, spouses, or other people close to the patient, notes from their doctor, therapist, or other specialists, and behavior observed both during and outside of the ADOS-2 and ADI-R administration. By getting as much information as possible, our experienced clinicians can provide an accurate diagnosis and make the best possible recommendations for moving forward.

Based on the data collected, we may recommend testing for other conditions or learning disabilities. This is because some conditions commonly occur with ASD, such as ADHD, anxiety, and intellectual disabilities. We may also want to rule out conditions that can look very similar to autism, such as OCD, Schizophrenia, sensory processing issues, or developmental delays.
