Shadow Syndromes

Book by John Ratey (1998) ISBN:0553379593

Describes the sub-clinical versions of various brain/mental health syndromes (ADD, Autism[/Asperger's, Depression, Anxiety, etc.), showing how the patient can be significantly effected while being difficult to diagnose. Also shows how similar many of these things are.

OTOH some accuse it of medicalizing any bit of neuro-atypical-ity.
