Aprosexia and bird-like movements.
Case 446. (Chavigny, October, 1915.)
A soldier of the dragoons, 25, entered Chavigny’s service May 30, 1915. He acted like a mechanical figure, requiring guidance. The face was without expression except for the mobile eyes, and sudden bird-like movements of the head, continually attracted to new noises and objects. An interlocutor was glanced at but not responded to. If an intense electrical shock was passed through his abdomen, for example, the man would look for a moment in that direction, but only the most fugitive defence reaction would be made, and the stimulus could be repeated with the same result, a moment later.
After three days, this aprosexia began to clear, and in four or five days, answers to questions and ordinary associations set in. Memory reappeared. It seems that he had been in concealment in the loft of a barn, when he saw his commanding officer carried by, having lost an arm and a leg. He lost consciousness and fell three meters, through the trapdoor of the loft. There was thus a combination of trauma and emotional shock. No external lesion was produced in the fall. His memory showed a very sharply defined gap for the period of his aprosexia with the bird-like movements, of eight days, and his memory was perfectly good up to the time of the fall. This is one of five cases observed by Chavigny, who remarks that there is something in the attitude of the young child which recalls the aprosexia of these patients. (Perhaps the phrase of James, “buzzing, blooming confusion” might be used.) One must go back to a period in the child’s development when he is not yet able to smile or keep his glance fixed on a shining object. On the whole, the resemblance is closer to the attitude of certain caged birds.
