The incoördinations of the nervous system in which there may be nocturnal enuresis are those commonly found in extremely neurotic children, and children who are under-nourished and anemic. Chorea, neurasthenia and hysteria are examples of conditions in which nocturnal enuresis is very common. Nervous children are easily disturbed during sleep and are prone to dream, at such times the innate interpretation of the vibrations produced by the urine in the bladder reaches the educated mind and there is not sufficient reasoning of the conscious mind to enable the child to realize where he is or to prevent the following of the natural desire to urinate. The inability of the child to control the bladder during acute illness must not be mistaken for habitual nocturnal enuresis; for this will be only temporary, and will disappear when the child recovers from the acute attack. Highly Acid Urine In some cases, the urine being highly acid, produces vibrations in the bladder which results in Innate Intelligence causing the sphincter muscle to relax, which results in the voiding of the urine. This is an adaptative action on the part of Innate to prevent the acidity of the urine from setting up an irritation in the bladder. If the urine remained in the bladder it would damage the tissues and call for an expenditure of energy for reparation; this is all prevented by getting the urine out of the bladder as soon as possible. The hyperacidity of the urine is the result of the lack of the expression of mental impulses in the body and should receive immediate attention, that the cause of the incoördination may be removed. When this is accomplished the nocturnal enuresis will cease. Excessive Quantity of Urine In some incoördinations there is abnormal thirst which results in the child drinking more water than is required for the normal bodily processes. The natural channel through which this excessive amount of water is excreted is through the kidneys. This results in the bladder being filled often, which necessitates the frequent passing of urine. The child might be able to control the bladder during waking hours and make his wants known; but in sleep, as the bladder becomes full, Innate would relax the sphincter muscle, which would allow the urine to escape in order to relieve the pressure. To overcome the nocturnal enuresis in a case of this kind, it is necessary to adjust for the cause of the excessive thirst; and when this is corrected, the bed wetting will cease.
