Dr. H. Dagonet (“Annales Médico-Psychologiques,” No. 1, 1895) draws attention to those cases which exhibit simultaneously delusions of a contradictory nature and to the alternation of different kinds of delusions, e.g., delusions of persecution with those of grandeur, etc.—cases which are usually classified as folie circulaire, melancholia with delusions of grandeur, megalomania with delusions of persecution, etc. A girl, for example, admitted under his care with “religious” melancholia of several months' duration, is seized with acute mania, with marked excitement lasting a year, and then recovers. Again: M. becomes affected with active melancholia, which lasts three years, and passes into a chronic condition, marked with delusions of self-importance and exuberant activity, etc. The explanation is generally obscure. Cases in which we find simultaneously delusions of well-being associated with ideas of depression, or hypochondriacal delusions with those of grandeur, etc., may belong to general paralysis, or alcoholism, or dementia. In the hypochondriacal form of general paralysis, for instance, one nearly always finds associated delusions of grandeur, of wealth, etc. (cases of D., G., J., G., etc.).
