Answer:
Answer explained below.Step-by-step explanation:
One cause or disturbance that can influence development during the prenatal period is maternal substance use, particularly the use of drugs and alcohol during pregnancy.
When a pregnant woman uses drugs or alcohol, the substances can cross the placenta and affect the developing fetus. This can result in a range of developmental abnormalities, such as low birth weight, small head circumference, poor growth, and developmental delays. The severity of these effects can vary depending on the timing and frequency of substance use during pregnancy.
Maternal substance use during pregnancy can also have long-term effects on the child's development. Children who were exposed to drugs or alcohol in the womb may be at increased risk for behavioral problems, learning difficulties, and mental health issues. They may also be more likely to engage in substance use themselves later in life.
Furthermore, prenatal substance exposure can have lasting effects on brain development. Research has shown that exposure to drugs or alcohol during key periods of brain development can lead to changes in the structure and function of the brain, which can impact learning, memory, and emotional regulation.
Overall, maternal substance use during pregnancy can have significant and long-lasting effects on a child's development, highlighting the importance of addressing substance use disorders among pregnant women to support optimal child development.
