One reviewer has commented on the difficulty of clarifying the core characteristics of and differences between atypical attachment styles and ways of categorizing more severe disorders of attachment.As of 2010, the American Psychiatric Association has proposed to redefine RAD into two distinct disorders in the DSM-V. Corresponding with the inhibited type, one disorder will be reclassified as Reactive Attachment Disorder of Infancy and Early Childhood.In regards to pathogenic care, or the type of care in which these behaviors are present, a new criterion for Disinhibited Social Engagement Disorder now includes chronically harsh punishment or other types of severely inept caregiving. Relating to pathogenic care for both proposed disorders, a new criterion is rearing in atypical environments such as institutions with high child/caregiver ratios that cut down on opportunities to form attachments with a caregiver. Differential diagnosis
The diagnostic complexities of RAD mean that careful diagnostic evaluation by a trained mental health expert with particular expertise in differential diagnosis is considered essential. Several other disorders, such as conduct disorders, oppositional defiant disorder, anxiety disorders, post traumatic stress disorder and social phobia share many symptoms and are often comorbid with or confused with RAD, leading to over and under diagnosis. RAD can also be confused with neuropsychiatric disorders such as autism, pervasive developmental disorder, childhood schizophrenia and some genetic syndromes. Infants with this disorder can be distinguished from those with organic illness by their rapid physical improvement after hospitalization. Autistic children are likely to be of normal size and weight and often exhibit a degree of intellectual disability.
