'You've never really grasped small talk, and would rather talk to a computer than another human being. Does that mean you have Asperger Syndrome (AS)? Actually, since the publication of the latest Diagnostic and Statistical Model of Mental Disorders (DSM-5), there is no longer an official diagnosis called Asperger Syndrome. But it is perfectly possible that you are an adult who is diagnosable with a relatively mild (high functioning) form of an autism spectrum disorder....'

How High Functioning Autism Is Diagnosed in Adults
[from the VERY WELL HEALTH web site]
These are some of the symptoms you may encounter on a daily basis. They may also be symptoms you experienced as a young child but learned to manage over time. They may include:
Sensory and Behavioral Symptoms
The most recent criteria for autism include sensory challenges that are common to all people on the spectrum. Sensory challenges (along with the social challenges described above) can lead to unexpected behaviors.
Sensitivity to light, sound, smell, touch, and taste. Like many people with other disorders (such as migraine), people with autism are unusually sensitive. While most neurotypical people, for example, can spend all day under fluorescent lights in a loud environment, most people with autism can't. Autistic people may also react strongly to smell or taste, or have a hard time with physical intimacy.
Need for physical pressure for calming. Temple Grandin, a major figure in autistic self-advocacy, actually built herself a "squeeze machine" as a way to help herself to stay calm in college.
Need to move or vocalize in unusual ways. This need, called "stimming," is a form of self-calming and may involve pacing, rocking, hair-twirling, humming, etc. It's difficult to control and can result in uncomfortable stares from the people around you.
Autistic meltdowns. Some adults with autism, even those with very high IQs, can become very frustrated and upset and find it impossible to control their words and actions. This response is sometimes called an "autistic meltdown." While it's rare for an adult with autism to act out in a violent way, even non-violent melt-downs can be frightening to the people who witness them.'
