![1. Disorders op General Activity. Tlie general activity is the total of tlje systemi(r reactions under the influence of ]»S3'^chic impressions. It maybe abnormal in two ways, either by excess oi- by default. In the first case there is excitement, in the second depression. Excitement.—Excitement consists in the exalta- tion of the general activity, or functional reaction. When very intense and generalized, it reveals itself in a disordered activity of the intelligence, sensa- tions, and acts that is absolutely uncontrollable. If less intense, it is limited to a simple exaggeration of the normal activity, and then affects more particu- larly the psychic or the motor sphere. It is the principal element of maniacal conditions, the varie- ties of which derive their characters from its degree of intensity and generalization. Depression.—Depression is the opposite condi- tion to excitement. It consists in a defect of expan- sion of the general activity, which ranges from sim- ple concentration of the reacti<m of the organism to its complete suppression. It then translates itself externally by an absolute innnobility or stupor. In a minor degree it may affect more particularly either the psj^chic or the somatic si)here. Like excite- ment it is characteristic of a special type of gen- eralized insanity, the conditions of lypemania or melancholia.](https://iiif.wellcomecollection.org/image/b21963009_0082.jp2/full/800%2C/0/default.jpg)
