No. 53: Sep-Oct 1987
In the psychological literature "folie a deux" is a common topic. It means that psychological illness can be contagious. We now find that the process can extend to whole families.
"Reports of folie a famille are rare; this may be the first reported case involving a Vietnam veteran. Expression of his paranoid schizophrenia involved delusions and hallucinations relating to Vietnam, and his wife and children shared his paranoia. Typical of follie a famille were the dominant family member, the threat of violence, and the family's social isolation, frequent crises, and stable membership."
