Autism is a disorder that is most often diagnosed in children before the age of five, but the higher functioning types of autism may be hard to diagnose in older children and adults.
Many studies have been conducted about techniques to diagnose autism in toddlers and young children because they are easier to work with during testing periods. They also have more obvious reactions when being tested for certain things.
However, this has made it difficult at times for some people to receive a proper diagnosis if their autism presents itself later in life.
One issue with diagnosing older children or adults rather than toddlers or younger children comes from the struggle of getting them to sit still long enough for someone to test them without causing too much frustration or anger.
Other issues that come with diagnosing older children and adults include the difference in when certain behaviors become common for people on autism when it’s harder to test children or adults on their fine motor skills or cognitive skills, and how they tend to act differently than most other children or adults their age. There are also cases where some individuals may not like being constantly tested by someone else; they may decide to stop the testing process before it even starts if they feel uncomfortable enough around them.
Those who work with these types of kids or adults tend to use more visual behavior cues rather than verbal behavior cues because most of these children tend to struggle with social interactions at times to how autistic affects their brain development.
It’s also hard for older children or adults to understand what autism is if they don’t already know about it. They may decide to stray away from the testing because they feel embarrassed about their actions, not realizing that it’s a common trait among other individuals on the spectrum.
