A dysfunctional family is a family in which conflict, misbehavior and often child neglect or abuse on the part of individual parents occur continuously and regularly. Children that grow up in such families may think such a situation is normal. Dysfunctional families are primarily a result of two adults, one typically overtly abusive and the other codependent, and may also be affected by substance abuse or other forms of addiction, or sometimes by an untreated mental illness. Parents having grown up in a dysfunctional family may over-correct or emulate their own parents. In some cases, the dominant parent will abuse or neglect their children and the other parent will not object, misleading a child to assume blame.
