My husband zones out if too much is going on!
The online journal Autism Research published a new study today on how MRI scans of brain circuitry might help us understand how the brains of people with HFA differ from the brains of people without spectrum disorders.
Researchers were able to measure six physical differences of microscopic fibers in the brains of 30 males with confirmed high-functioning autism and 30 males without autism. How these findings might relate to adults with Asperger's is unknown. The scans helped researchers identify adults in the study with HFA with over 90% accuracy. While the study was small, the progress is promising, as researchers are increasingly in search of definitive evidence of brain differences related to autism. Identifying such differences may serve to clarify diagnosis, which is a largely subjective process at present.
While the study authors find the results promising, MRI scanning for diagnostic purposes is a long way from becoming a widely used tool.
Using the MRI, the study authors measured how the water in the brain flows along the axons or nerve fibers in the parts of the brain that control language, social and emotional functioning. The scans revealed that the wiring of the brains of those with autism was disorganized compared with the brains of a typical person without autism.
Such results are important for adults with Asperger's to consider, and important for their partners to consider. The communication difficulties which can cause immense frustration for the partner of an adults with AS are understood today, with increasing clarity, to result from neurological brain differences.
Currently there is no biologic test for autism; clinicians working with adults must gather information about current and past functioning to piece together a clinical picture. This process can be tricky, as adults have often adapted to social rules and settings, making what might be more easily identifiable "Aspie" behaviors difficult to see. Often family members are the true observers of these behaviors, but are left without a framework with which to understand them.
Researchers in 1997 (Baren-Cohen) found that adults with Asperger’s have difficulty reading mental states by looking at a person’s eyes – not only the expressions of the eyes, but the location of their gaze. These findings were expanded upon in 2002 (Rutherford), when researchers found that adults with AS have difficulty extrapolating people’s mental states from their vocalizations.
Take just a minute to imagine some of the implications.
We constantly use our flexible and dynamic ability to read and react to myriad social cues to avoid social disasters. Adults with AS who may not have this luxury are left trying to navigate the social landscape with no real map. The negative reactions, indifference and subtle (or not-so-subtle) rejection they deal with can lead to social anxiety, confusion, avoidance, isolation, even depression.
You can cut some slack for those who struggle to keep up with an ever-changing social context by resisting the urge to expel them from the group. You can resist the urge to mock or embarrass. If you have social gifts, you can share them. Remember, adults with AS are often developing the computer programs you work with and performing the neurosurgery you may benefit from.
Becoming aware of his “rule” was very helpful to this man. Learning to become aware of, articulate and evaluate these rules can be central to understanding a huge source of self-judgment and self-criticism. This man began to systematically challenge this rule: did he really believe work defines manhood? Did he know of any “real” men who did not work? How could he lower his anxiety when engaging in leisure activities?
This scenario may not ring a bell for you, but you may find that you do adhere to other rigid rules – and you may find you become upset when your rules are broken. Rules can make the world feel safer – they can add structure to a seemingly chaotic and unpredictable reality. When rules stop working for you – and you start working for them – you’ll know it. You’ll find yourself becoming angry and frustrated. Others might complain of your bad attitude or rudeness. Your anxiety may climb.
Becoming aware of your automatic thoughts, or rules, is often the first step in replacing maladaptive rules with healthier rules that reflect your true values. We all have internal rules that help us navigate the social world, and being conscious of them can help you feel more relaxed and be kinder to yourself and others.
