Phasic and tonic alertness in preterm 5-year-old healthy children.

Preterm delivery may interrupt the intrauterine brain development and implies a risk factor for the developing brain. In the long term, most frequently particular forms of attention deficits are described which refer to the basic aspects of attention i.e.

Reduction of the event-related potential P3 in preterm born 5-year-old healthy children.

Objectives: An abbreviated gestational period may interrupt intrauterine brain development and constitutes a serious risk factor. Many preterm children show some form of attention deficits in later life. However, there is ambiguity about the nature and extent of these attention deficits in the literature.

ATTENTION FUNCTIONING IN CHILDREN WITH PRENATAL DRUG EXPOSURE.

Children born to drug abusers are exposed to teratogenic influences on intrauterine brain development and undergo postnatal withdrawal. We investigated the interplay of different domains and levels of attention functioning in 24 prenatally exposed and 25 nonexposed children who were 5 to 6 years old. Assessment included parent ratings and neuropsychological and electrophysiological methods.
