[Sleep cycles of hydrocephalic infants (author's transl)]

The authors have studied the sleep of 6 hydrocephalic infants. In 4 cases disturbed sleep was noticed, characterized by insomnia in 2 cases, and frequent interruptions of sleep in the other 2 cases. In the last cases no other particular alterations were observed. The research was continued in 2 cases, operated on with the Pudenz Valve. In one of which the valve functioned well, sleep was restructured. In the second case the valve did not function well and sleep was not restructured. This suggests the hypothesis that the endocranial hypertension may alter the sleep cycles.
