Child victims of severe parental alienation (e.g. victims of pathogenic parenting) are at high risk for many medical problems later in life, according to a landmark study from the CDC (Center for Disease Control) called the Adverse Childhood Experiences Study ACES.
Severely alienated children (e.g. victims of pathogenic parenting) have an astronomical ACES score of at least 5 out of 10, possibly going as high as 6 out of 10, by scoring one point for each the following: 1) divorce, 2) emotional abuse, 3) mental illness in the family (e.g. borderline or narcissist) 4) emotional neglect (role reversal relationship), 5) domestic violence (the DoJ says DV includes “damaging one’s relation with his or her children” …. and “forcing isolation from family/friends” ) and 6) there may be false allegations of something that could put someone in prison, which arguably counts for at least another point, especially if they are in jail after being arrested on a false allegation. Or the erased parent may be put in jail after falling slightly behind on child support, which is way higher because they are erased, and the abusive alienating parent got custody.
These problems are also somewhat consistent with observations from the American Psychiatric Association on disordered parenting.
