XXXX . a review of the concept and an unusual case of folie    famille.

@entity24602 @entity1 @entity4750 @entity716
@entity4750 (or @entity24602 ), also known as folie    deux, is a fairly uncommon disturbance characterized by the presence of similar @entity716 in two or more individuals. Most often the symptoms are delusional. Usually the 'primary' case, i.e. the individual who first develops @entity716 , can be distinguished from one or more 'secondary' cases, in whom the symptoms are induced. We discuss the concept of @entity24602 and consider various aetiological, clinical and diagnostic issues related to the disturbance. We also describe a case of folie    famille, this condition being a type of @entity24602 . The case involves a couple and their 12-year-old son. The @entity1 's father is the 'primary' case, whilst the @entity1 and his mother are both 'secondary' cases. The @entity1 was admitted to our @entity1 and adolescent psychiatric unit for in- @entity1 treatment. Treatment success was moderate in terms of improving the features of folie    famille in the three individuals involved.
