The history showed that there had been convulsions in the third and fourth years of the patient’s life. There had been, however, nothing epileptoid in the later childhood or developmental years of the patient. However, a sister of the patient had suffered since childhood from convulsions. It remains a question whether this episode is to be regarded as reactive epilepsy--reactive, namely, to experiences in the war--or whether we are dealing with a true epilepsia tarda. _Re_ this episode following bullet wound, the compiler has placed it after Mairet and Piéron’s case of Brown-Séquard epilepsy, but apparently Bonhoeffer regards his case as probably a reactive one. Unlike the case of Mairet and Piéron, Bonhoeffer’s case had an epileptic soil (convulsions in childhood and epileptic sister). _Re_ the so-called reactive epilepsies, see remarks by Bonhoeffer under Case 57. Epilepsia tarda in a lance-corporal without hereditary taint or previous history save dizzy spells and excitability. =Case 71.= (BONHOEFFER, July, 1915.) A reserve lance-corporal, 24 years--a soldier from 1911 to 1913 without disciplinary record, and in his second year becoming lance-corporal--was in the campaigns in Belgium, East Prussia, and Poland, making long marches and going through several battles. In the middle of October, 1914, he fell from a horse and suffered a contusion of the thorax, after which blood appeared in the sputum. In November he was brought to the reserve hospital in Berlin, and there had convulsive seizures. Before transfer to the Charité Clinic, a seizure occurred, and he was brought into the clinic in a characteristic dazed state. Thereafter he was clear but often out of humor and irritated. Three weeks later came a brief attack, probably epileptic in nature, with restless half-delirious sleep following. There was nothing in childhood or in the family history to indicate epilepsy. However, the patient himself stated that from 1913 onward, after his period of military service, he had from time to time felt attacks of dizziness after exertion, and that he had become more easily excitable than before. The attacks in the lance-corporal are probably not to be attributed to the thoracic contusion, according to Bonhoeffer, because of the long period that elapsed after the thoracic injury, and their development nocturnally without special occasion. According to Bonhoeffer, we are probably here dealing with a late epilepsy.
