All these manifestations are best controlled by selecting a suitable environment, and as a rule the character of the environment is determined by the temperament and disposition of those who live in close contact with the patient. Like the tiny children with whom we have dealt so far, the behaviour of neuropathic persons is subject wholly to the direction of stronger and more dominant natures. With faulty management at the hands of those around them, no matter how loving and patient these may be, the conduct of the neurotic tends to become abnormal. In children beyond earliest infancy we recognise a gradual approach to the conditions of adult life. Fractiousness and naughtiness, ungovernable fits of temper, inconsolable weeping and inexplicable fears should disappear with early childhood even if management has not been perfect. If they persist to older childhood we shall find in an increasing percentage of cases evidence of definite neuropathic tendencies which urgently call for investigation and for a precise appreciation of the nature of the abnormality. It may be that the only effective treatment is that which we recognise as essential in the grosser mental disturbances--removal from the surroundings in which the abnormal conduct has had free play, and separation from the relatives whose anxiety and alarm cannot be hidden. In young nervous children fear is the most prominent psychical symptom. The children are afraid of everything strange with which they come in contact. They are afraid of animals, of a strange face, or an unfamiliar room. Older children usually manage to control themselves, suppress their tears, and prevent themselves from crying out, but it is nevertheless easy to detect the struggle. Often we find those distressing attacks to which the name "night-terrors" has been given. The child wakes with a cry,--usually soon after he has gone to sleep,--sits up in bed and shows signs of extreme terror, gazing at some object of his dreams with wide-open startled eyes, begging his nurse or mother to keep off the black dog, or the man, or whatever the vision may be. Even after the light is turned up and the child has been comforted, the terror continues, and half an hour may elapse before he becomes quiet and can be persuaded to go back to bed. In the morning as a rule he remembers nothing at all.
