Microcephaly
Causes of Microcephaly
Correct Statement
Microcephaly is a rare neurological condition characterized by an abnormally small head and brain size, typically found in infants. It can result in various developmental issues, including intellectual disabilities, motor delays, and speech problems.
Causes of Microcephaly
- Genetic Factors: Microcephaly can be caused by genetic factors, such as certain genetic mutations or chromosomal abnormalities.
- Maternal Infections: Infections during pregnancy, such as Zika virus or cytomegalovirus, can increase the risk of microcephaly in infants.
- Maternal Malnutrition: Poor maternal nutrition during pregnancy can also contribute to the development of microcephaly in infants.
- Maternal Exposure to Toxic Chemicals: Exposure to toxic chemicals, such as alcohol, certain medications, or environmental toxins, can potentially lead to microcephaly in infants.
Correct Statement
Both statements are correct. Microcephaly is indeed a rare neurological condition found mainly in infants, and it can be caused by various factors, including maternal exposure to toxic chemicals.

Consider the following statements with reference to the Microcephaly:1...
Recently, a study revealed that a gene called SASS6 and its variants have been implicated in a developmental process that causes microcephaly.
- It is a rare neurological condition in which an infant's head is much smaller than the heads of other children of the same age and sex.
- Sometimes detected at birth, microcephaly often occurs when there is a problem with brain development in the womb or when the brain stops growing after birth.
- It can be caused by a variety of genetic and environmental factors. Children with microcephaly often have developmental issues.
- Most children with microcephaly also have a small brain, poor motor function, poor speech, and abnormal facial features, and are intellectually disabled.
- The most common causes include:
- Infections during pregnancy: toxoplasmosis (caused by a parasite found in undercooked meat), Campylobacter pylori, rubella, herpes, syphilis, cytomegalovirus, HIV and Zika;
- Exposure to toxic chemicals: Maternal exposure to heavy metals like arsenic and mercury, alcohol, radiation, and smoking;
- Pre- and perinatal injuries to the developing brain (hypoxia-ischemia, trauma);
- Genetic abnormalities such as Down syndrome; and severe malnutrition during fetal life.
- Symptoms: Many babies born with microcephaly may demonstrate no other symptoms at birth but go on to develop epilepsy, cerebral palsy, learning disabilities, hearing loss and vision problems.
- Treatment: There is no specific treatment for microcephaly.
Hence both statements are correct.
