It seems as if auto- and hetero-suggestion can be eliminated from the genesis of these attacks. Neither hysterical nor epileptic crises have preceded or ever alternated with these seizures. Nevertheless, on the organic side, the patient had a general increase of tendon reflexes on the left side, most marked in the knee-jerk, and fell to the left in voltaic vertigo. There was a left hemiparesis, apparently of organic origin, which had been determined as far back as July, 1915. There was no true dementia. Past memories were but slowly recalled, and inattention interfered with the fixation of recent memory. He complained of troubles in his sleep and dreamed of war experiences somewhat analogous to those in his attack of amnestic delirium. After the seizure, there was a marked hebetude and mental inactivity, torpor, and a severe headache. The case was presented to a special commission as one of epilepsia larvata in a person hereditarily predisposed who had never before presented epileptic signs, suffering from a disease characterized by frequent short attacks of hallucinatory and delirious automatism, following shell explosion which had at the same time produced a slight left-sided hemiparesis and mental inhibition. To illustrate an epileptic theory of Shell-shock; three cases: 1. Fugue; minor symptoms: later, epilepsy. 2. Epileptic confusion eight months after explosion. 3. Mine explosion: stammering replaced by mutism; mutism replaced by epilepsy. =Case 82.= (BALLARD, 1917.) Atmospheric concussion from shell explosion, October, 1915, was followed by unconsciousness in a soldier described by Ballard. Blindness for a month followed recovery of consciousness. “Neurasthenia” (anxiety neurosis) after return of sight. Apparently nearly complete recovery after latent period of a few weeks. Return of blindness in one eye in December. Five days automatic wandering (the man was found in a west country town five days after leaving home to rejoin his dépôt and seen by a medical officer who reported that he was dazed and amnestic for that period); admission to second Eastern General Hospital, December 15. On admission he proved to be suffering from minor hysterical symptoms such as an inability to open his eyes and to see clearly when the lids were raised. The symptoms rapidly cleared up under suggestive conversation and did not return except for amnesia and slight emotional depression. He remained well until December 25. On that day he began for the first time to have definite epileptic fits and nocturnal epileptic delirium. In January he was discharged as an epileptic. There was no epileptic temperament or feeblemindedness. Finally, there had never been any personal or family neuropathic or psychopathic history. =Case 83.= (BALLARD, 1917.) A soldier was blown up, April, 1915, and had a spell of unconsciousness. Later, pains in the head, slight amnesia and a condition of asthenia developed.
