The first thing I would do is get a good assessment NOW from a therpist who has experience and training treating children with trauma-attachment disorders. This will give you a current diagnosis and treatment plan. Many children are misdignosed with ADHD, etc. I'd want to consider and have ruled in or out Sensory-Integration disorders as these can mimic ADHD. I'd also want ruled in/out Bipolar Disorder as if that is going on the child does need proper medication treatment. Finally, if your child has RAD, your child need attachment-based treatment (see attach.org for therapists in your region) and see my website
www.center4familydevelop.com for some checklists and information on these conditions you may find helpful. The trauma-attachment disorder must be treated with therapy and attachment-based parenting methods for the child to heal.
