I think the defense will be claiming Aspberger's
Um... Asperger's syndrome would be the wrong diagnosis no psychologist would ever argue it for Casey.
Asperger's Syndrome: "Not pick up on social cues and may lack inborn social skills, such as being able to read others' body language, start or maintain a conversation, and take turns talking."
Casey: Very manipulative, can easily read social cues, has trouble NOT starting a conversation.
Asperger's Syndrome: "Dislike any changes in routines."
Casey: Dislikes routines.
Asperger's Syndrome: "Appear to lack empathy."
Casey: Pretends to have empathy
Asperger's Syndrome: "Have heightened sensitivity and become overstimulated by loud noises, lights, or strong tastes or textures. "
Casey: Likes to party with loud noises, and lights.
Asperger's Syndrome: "Have a formal style of speaking that is advanced for his or her age. For example, the child may use the word 'beckon' instead of 'call' or the word 'return' instead of 'come back.'"
Casey: Has a non formal style of speaking that is limited for her age. For example Casey uses the nickname "Cookie" instead of "Fellow inmate".
Asperger's in adulthood:
"Asperger's syndrome is a lifelong condition, although it tends to stabilize over time, and improvements are often seen. Adults usually obtain a better understanding of their own strengths and weaknesses...Some traits that are typical of Asperger's syndrome, such as attention to detail and focused interests, can increase chances of university and career success. Many people with Asperger's seem to be fascinated with technology, and a common career choice is engineering. But scientific careers are by no means the only areas where people with Asperger's excel. Indeed, many respected historical figures have had symptoms of Asperger's, including Wolfgang Amadeus Mozart, Albert Einstein, Marie Curie, and Thomas Jefferson. "
Casey in adulthood:
Complete ADHD, and probably can't spell "engineering".
