A dysfunctional family is a family in which conflict, misbehavior, and often child neglect or abuse on the part of individual parents occur continually and regularly, leading other members to accommodate such actions. Children sometimes grow up in such families with the understanding that such an arrangement is normal. Dysfunctional families are primarily a result of co-dependent adults, and may also be affected by addictions, such as substance abuse (alcohol, drugs, etc.), or sometimes an untreated mental illness. Dysfunctional parents may emulate or over-correct from their own dysfunctional parents. In some cases, a "child-like" parent will allow the dominant parent to abuse their children.
