Dysfunction comes in two general categories.
Families with high level of conflict, regardless of causes of the conflict, are prone to add stress to the child and be less able to provide a desirable stable routine. Secondly, dysfunction may be driven by unrecognized or inadequately treated bipolar disorder in one or more family members. This is often expressed as inconsistent, volatile anger or violence, or in erratic discipline, ranging from inattention to harshly primitive actions.
