As to the relation of the concussion two years before to the epileptic attack, Bonhoeffer is inclined to interpret the case as one of genuine “reactive” epilepsy on the basis of continuous overstrenuous work for a period of weeks. He regards the previous concussion as soil for this epilepsy.
Re amount of stress occasionally required to bring out epilepsy, compare Hurst’s Cases [64] and [80]. It may be recalled that Bonhoeffer is decidedly of the belief that exhaustion has not brought about any actual psychoses, calling attention to the remarkable absence of psychoses among the Serbians after their exhausting campaigns. A general review of war experience indicates, according to Bonhoeffer, the marked power of resistance of the healthy brain.
Nocturnal narcoleptic seizures accompanied by spells of somnolence in the day, both to be regarded as due to the “brain fag” of trench life.
Case 77. (Friedmann, July, 1915.)
A tradesman, 23, had been in the German infantry since the beginning of the war. Never sick, he had been, in a general way, nervous; and a brother had had, at the age of 30 years, some sort of severe brain disease, in which he became blind, dying a year later.
The man was for a long time in the trenches and proved himself a courageous and stalwart soldier. He went to hospital after a slight bullet wound of the leg, with a benign paralysis of the peroneus.
In the hospital he began to show a somewhat pronounced emotional depression, with a nervous tachycardia.
Friedmann reports the case on account of certain peculiar seizures which, upon the man’s own story, had begun five weeks before, in the field, although he had told no one about them. He had never felt anything like them before. At first, they came three to five times almost every night. He would suddenly wake and find himself unable to move, to speak, or even to think. These seizures, however, were not accompanied by any feeling of anxiety or any respiratory distress. Consciousness remained clear, and after 10 or 15 seconds, he could begin to think normally again. It was clearly a question of psychopathic absences of a mild narcoleptic type, occurring, however, only at night.
Daytimes, also, throughout the whole period in which the nocturnal absences occurred, there were seizures of another description. During the many hours in which he had to sit in the trench, about twice a day for half an hour long, he would plunge suddenly into a sort of irresistible lethargy. Without any external occasion whatever, there would be a feeling of great fatigue. In the spell he could not move or think, would lean his head upon his hand. He was unable to overcome the feeling of weariness and became convinced that he was ill, and that the fatigue could not be natural. However, he did his work like the rest. Friedmann interprets these spells as a kind of imperfect sleep.
