Environmental toxicants and fetal development is the impact of different toxic substances from the environment on the development of the fetus.This article deals with potential adverse effects of environmental toxicants on the prenatal development of both the embryo or fetus, as well as pregnancy complications.
Learning language as an infant also requires fetal memory. It is now known that the mother's voice is clearly heard from inside the womb and that the fetus can differentiate speech sounds, particularly the phonemes (a single segment of sound) in speech. This is evident in the baby when born, showing many signs of early language comprehension.
The effects of exposure to the Ramadan fast can even be observed in mental disorders. In a study conducted in Uganda it was concluded that exposure to the fast, early in a pregnancy effectively doubles the likelihood of a person having a cognitive disorder of some kind.
Prenatal cocaine exposure (PCE), theorized in the 1970s, occurs when a pregnant woman uses cocaine including crack cocaine and thereby exposes her fetus to the drug.Babies whose mothers used cocaine while pregnant supposedly have increased risk of several different health issues during growth and development and are colloquially known as crack babies.
Fetal programming, also known as prenatal programming, is the theory that environmental cues experienced during fetal development play a seminal role in determining health trajectories across the lifespan. Three main forms of programming that occur due to changes in the maternal environment are:
New research suggests fluoride exposure during pregnancy could be linked to neurobehavioral issues in kids. But even the study’s authors — who were prompted to examine the issue based on ...
Sandman and Davis studied "125 full- term infants at 3, 6, and 12 months of age" [8] to determine the effects of maternal cortisol timing differences on development. They found that "exposure to elevated concentrations of cortisol early in gestation was associated with a slower rate of development over the 1st year and lower mental development ...
Partial fetal alcohol syndrome (pFAS) refers to individuals with a known, or highly suspected, history of prenatal alcohol exposure who have alcohol-related physical and neurodevelopmental deficits that do not meet the full criteria for FAS.
