Shortly after, the rest of Kevin’s family returns home and gives Kevin what appears to be the most positive reception he has ever received, their former attitudes of him miraculously transformed.
Diagnosis: Based on Kevin’s symptoms, I diagnose him with Reactive Attachment Disorder and Bipolar Disorder. Kevin expresses symptoms of both disorders in the film, and one can only speculate as to what happens outside of it. The main criteria Kevin meets for Reactive Attachment Disorder comes from his family. In the DSM-V, Kevin meets the criteria for showing little emotion to his caregivers and has been consistently neglected by his parents, cousins, siblings, aunts and uncles. Shortly after Kevin is sent to the attic to sleep, he wishes that his family would just disappear.
