If Dagonet be accepted as summarizing the early French work, we can conclude that their generalizations were on the whole quite sound. These were: that stupor is an abnormal mental reaction, usually psychogenic but often the result of exhaustion, that it consists in a paralysis of emotion, will and intelligence; that the prognosis is usually good; that mental stimulation may produce recovery. What remained to be done after this work was the refinement in detail of these generalizations, particularly in respect to the differentiation of prognostically benign and malignant types. But other Frenchmen did not take up this work, apparently, for the brilliant psychopathologists of the next generations attended to stupor only in so far as it was hysterical. An Englishman, however, soon took up the task, adding more exactness to his formulations. Newington[14] published his important paper in 1874. A nascent stage of stupor, he thinks, is a common reaction to great exhaustion, “such as hard mental work, prolonged or acute illness, dissipation, etc.” Such conditions, like the grave psychotic forms, he regarded as due to physical exhaustion of the brain cells, but, since he thought psychic stress could produce this exhaustion, this “organic” view did not bias his general formulations. He makes a division into two stupors: Anergic Stupor and Delusional Stupor. The former may be primary, being generally caused by a sudden intense shock (Esquirol’s “Acute Dementia”), or secondary (a) to convulsions of any kind, (b) to mania in women, (c) to any other prolonged nervous exhaustion. The delusional form results from (a) intense melancholia, (b) from general paralysis in which it may be intercurrent, (c) from epileptic seizures. When one examines his points of difference between these two types, it becomes clear that Newington really gave an excellent differentiation of benign and malignant stupor--in fact, it is the only serious attempt at such discrimination prior to this present work. What is more remarkable is the fact that, although he clearly saw the clinical differences, he failed to see that the two types differed prognostically.
