1. DEVELOPMENTAL CHALLENGES IN PRENATAL DEVELOPMENT

Chromosomal Abnormalities

These involve an incorrect number or structure of chromosomes.

Down Syndrome

(Trisomy 21) Caused by an extra copy of chromosome 21, leading to flattened facial features, heart defects, and intellectual impairment.

Turner Syndrome

Occurs when a female is born with a missing or partially missing X chromosome (XO).

Klinefelter Syndrome

Occurs in males with an extra X chromosome (XXY).

Single Gene Disorders

Inherited illnesses where one or both parents carry a gene for a specific disease (e.g., Sickle Cell Anemia, Cystic Fibrosis, Tay

Central Nervous System Malformations

Issues with the development of the brain and spinal cord.

Alcohol

Can lead to Fetal Alcohol Spectrum Disorders (FASD), characterized by small head size, abnormal facial features, heart defects, and intellectual disability.

Smoking

Linked to low birth weight, weakened immune system, poor respiration, neurological impairment, premature birth, and stillbirth.

Psychoactive Drugs

Associated with low birth weight and neurological impairment; babies born with heroin addiction may experience withdrawal.

Rubella

(German Measles) Can cause birth defects and deafness.

Cytomegalovirus (CMV)

Can lead to neurological problems, hearing loss, and intellectual delay.

Toxoplasmosis

An infection that can affect the developing fetus, caused by a parasite in animals.

Herpes Viruses

Congenital transmission can lead to long-term neurological problems

Sexually Transmitted Infections (STIs)

Like Gonorrhea and Chlamydia; can cause ophthalmia neonatorum (leading to blindness if untreated).

Zika Virus

Can cause microcephaly and other severe brain defects.

Diabetes (Uncontrolled)

Increases the risk of congenital anomalies, stillbirth, and macrosomia (large baby).

Folic Acid Deficiency

A key factor in causing neural tube defects (spina bifida).

Iron Deficiency

(Anemia) Can lead to tiredness, weakness, and other symptoms in the mother.

Placental Abruption

The placenta separates from the uterus prematurely.

Placenta Previa

The placenta partially or completely covers the cervix.

Placenta Accreta

The placenta attaches too deeply into the uterine wall.

Placental Insufficiency

The placenta is damaged or improperly formed, leading to inadequate nutrient and oxygen delivery.

Polyhydramnios

Too much amniotic fluid; can lead to premature membrane rupture and preterm labor.

Oligohydramnios

Too little amniotic fluid; can cause pressure on the fetus and damage to lungs.

Intrauterine Growth Restriction (IUGR)

The fetus grows too slowly, often due to issues with the placenta or maternal health.

Prematurity and Low Birth Weight

Babies born before 37 weeks; higher risk for health problems due to underdeveloped organs.

Rh Factor Incompatibility

An immune reaction from the mother's body against the baby's blood type.

Gestational Diabetes

High blood sugar levels in the mother during pregnancy; can lead to a large baby and complications during delivery.

Preeclampsia

High blood pressure in the mother during pregnancy, potentially impacting blood flow to the placenta and fetal growth.

Umbilical Cord Abnormalities

Issues with the umbilical cord's attachment or position (e.g., umbilical cord prolapse).

Miscarriage and Stillbirth

Loss of pregnancy before (miscarriage) or after (stillbirth) 20 weeks gestation.

Chronic Maternal Illnesses

Conditions like obesity, high blood pressure, and autoimmune diseases.

Maternal Age

Pregnancies in very young or older mothers (over 35) tend to have higher risks.
