New photos, details emerge of Newtown mass shooter Adam Lanza (The Lookout)
[...]Adam was diagnosed at a young age with sensory integration disorder, a medically controversial diagnosis that meant Adam had trouble coping with bright lights, loud noises, and knowing when he was in pain. Later, when he was in middle school, Adam was also diagnosed with Asperger's, a condition related to autism that can make social interaction challenging. (Medical experts cautioned that autism disorders are not associated with violent behavior.)

A friend of Nancy’s remembered that when Adam was just six years old, he did not like to be touched. If children his age touched them, he recoiled or became upset. "He was angry with them," Marvin LaFontaine, Nancy's friend, told Frontline. Richard Novia, who co-founded the tech club Adam joined while he attended Newtown High School, told Frontline Adam would have "episodes" as a teen where he would completely withdraw from the world, sometimes sitting in a corner, motionless.

Nancy raised Adam and his older brother in their Newtown home on her own after she and her husband separated in 2001. In 2009, the couple officially divorced, and Adam abruptly cut off contact with his father in 2010 for reasons that are unclear.
