band of Gennari.[2][3]

In the field of psychiatry, Baillarger did research on the involuntary nature of

hypnagogic state (the intermediary stage between sleep and wakefulness). In 1854 he provided a description of a psychiatric disorder involving both manic and depressive episodes in the same individual, a condition that he referred to as folie à double forme (dual-form insanity). Unbeknownst to him at the time, another French psychiatrist, Jean-Pierre Falret (1794-1870), had described fundamentally the same condition (with a number of salient differences) in an article prior to Baillarger's findings.[4]
Falret referred to the disorder as folie circulaire (circular madness).
