More commonly, perhaps, neuropathy exhibits itself in an undue
tendency to show signs of fatigue upon exertion of any sort, mental or
physical. Sustained interest in any pursuit or task becomes
impossible. Nameless fears and unaccountable sensations of dread
establish themselves suddenly and without warning, and may be
accompanied on the physical side by palpitation, flushing, headache,
or acute digestive disturbances.

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.
