Q

Why does the mother using drugs affect the developing fetus?

A

Because the developing brain contains the same receptors as the adult brain:
* drugs affect behavior in utero
* drugs lead to neuroadaptations in adults, and so they will can also lead to neuroadaptation in the developing fetus

Study These Flashcards
A
  • childhood cancer
  • premature birth
25
What are the teratogenic effects of weed consumption?
* reduced fetal growth * reduced head circumference * decreased inner-diameter of aorta
26
What are the long-term behavioral effects of smoking? Impairs...
* high order executive function * attention * visual memory * impulsivity
27
What neuroadaptation occurs to the fetus as a result of weed use during pregnancy?
reduction in DA D2 receptors
28
# NSDUH -2016 to 2017 rates What percent of pregnant women used weed in the past month?
7%
29
# NSDUH 2016-2017 Rates What percent of pregnant women smoke weed in the first trimester?

30
How did COVID impact weed use during pregnancy?
Increased from 6.75% (before covid) to 8.14% (after covid)
31
What terms are given to babies when they were exposed to cocaine in utero?
* crack baby * jittery baby syndrome
32
What happens to a pregnant mother using cocaine due to the drug's sympathomimetic effects?
vasoconstriction
33
What happens due to vasocontriction from cocaine use in pregnant women?
decreased blood flow, which decreases oxygen to placenta and baby
34
What can happen as a result of decreased oxygen flow to placenta and baby with cocaine use by mother?
* placental detachment * fetal death * low birth weight * preterm labor
35
What are the direct effects of mother using coke to the fetus?
Neonatal Neurological Syndrome, which includes: * poor sleeping * poor feeding * tremors/seizures
36
What are the long-term behavioral effects that can happen from cocaine use during pregnancy?
* ADHD/ other learnnig disabilities * Difficults dealing with multiple stimuli at onece * difficulty with unstructured situations
37
What are the prenatal neuroadaptations that occur as a result of cocaine use? (PFC BDNF study)
* Embyonic: less BDNF than controls * Juvenile: more BDNF than controls (women much higher than males) * Adult: more BDNF than controls (especially with men)
38
Do healthy women or men have more BDNF?
women
39
How does brain activity change for controls vs those who were prenatally exposed to coke?
* Brain activity decreases for controls over time * Brain activity increases for cocaine exposed overtime
40
What disorder occurs due to opioid use during pregnancy?
Neonatal Opioid Withdrawal Syndrome (NOWS) | previously called NAS
41
What is the rate of NOWS? How has it changed?
* rates dramatically increased due to increased opioid abuse * now at 7% (2019)
42
What are the symptoms of NOWS?
* similar to those of opioid withdrawal in adults * irritability/crying * anxiety * abnominal distress * strabismus
43
What are the long-term behavioral effects associated with opioid use during pregnancy?
* cognitive function delay * anxiety * aggression * disruptive/inattentive behavior | not well known!
44
What are the neuroadaptations associated with opioid exposure in utero? Which sex experiences this worse?
* impaired working memory * reduced neurogenesis | much worse in females (practically sex-specific)
