Neurodevelopmental problems in maltreated children referred with indiscriminate friendliness.
Expect multiple neuro-psych diagnoses, not just attachment issues, in maltreated adopted kids who hug strangers.
01Research in Context
What this study did
Kočovská et al. (2012) looked at adopted school-age kids who had been badly hurt early in life.
All children showed indiscriminate friendliness—hugging strangers, going off with anyone.
The team gave full neuro-psych exams to map ADHD, PTSD, RAD, language, and IQ problems.
What they found
Almost every child carried more than one diagnosis. ADHD and PTSD were the most common.
Average IQ sat about 15 points below typical peers, and many had language delays.
The picture is complicated; severe early harm leaves many lasting marks at once.
How this fits with other research
Vervoort et al. (2014) studied the same kind of friendly kids and saw something that seems opposite: the children felt good about themselves and trusted teachers.
The two studies do not clash. Eva shows inside-the-brain damage; Eleonora shows outside social views.
Davidson et al. (2015) warns that RAD and autism can look alike. Use structured tests, not just parent forms, to sort them out.
Soylu et al. (2013) adds that kids with ID who are abused often face worse abuse and later conduct issues—another layer to screen for.
Why it matters
When a friendly adopted child lands on your caseload, plan for a mixed stack of needs.
Check for ADHD, PTSD, language gaps, and low IQ while you build trust.
Pair Eva’s full-battery idea with Claire’s structured play tasks to tell RAD from ASD.
This keeps your treatment plan tight and your referrals on target.

03Original abstract
We aimed to explore the extent of neurodevelopmental difficulties in severely maltreated adopted children. We recruited 34 adopted children, referred with symptoms of indiscriminate friendliness and a history of severe maltreatment in their early childhood and 32 typically developing comparison children without such a history, living in biological families. All 66 children, aged 5-12 years, underwent a detailed neuropsychiatric assessment. The overwhelming majority of the adopted/indiscriminately friendly group had a range of psychiatric diagnoses, including Attention Deficit Hyperactivity Disorder (ADHD), Post-Traumatic Stress Disorder (PTSD) and Reactive Attachment Disorder (RAD) and one third exhibited the disorganised pattern of attachment. The mean IQ was 15 points lower than the comparison group and the majority of the adopted group had suspected language disorder and/or delay. Our findings show that school-aged adopted children with a history of severe maltreatment can have very complex and sometimes disabling neuropsychiatric problems.
