[Semeiology of anxiety].

The difference of concept between somatic anxiety (" angoisse ") and psychic anxiety (" anxi été") as it was considered by authors in the past, has now fallen into disuse. However, it is worth considering this difference on the basis of the recent data relative to the selective effect that certain antidepressant drugs may have on panic attacks, while they have no effect on the basic anxiety. Consequently, a new nosography could then be considered in function of several factors: the reaction to imipramine, the preponderance in the disorders of their acuity and of the somatic impact, the spontaneous appearance of these same disorders.
