abnormalcy is a condition where a baby’s head is much smaller than expected. throughout physiological conditions, a baby’s head grows as a result of the baby’s brain growing. abnormalcy will occur because a baby’s brain has not developed properly during pregnancy or has stopped growing once birth, which ends up during a smaller head size. abnormalcy will be an isolated condition, which means that it will occur with no alternative major birth defects, or it can occur together with other major birth defects.

Severe abnormality could be a lot of serious, extreme variety of this condition wherever a baby’s head is far smaller than expected. Severe microcephaly may end up as a result of a baby’s brain not developing properly throughout pregnancy, or the brain beginning to develop properly and so was broken at some purpose during pregnancy.
Medical terms
Microcephaly (my-kroh-SEF-uh-lee) is a rare medical condition within which an Associate in Nursing infant' head is way smaller than the heads of alternative kids of identical age and sex. Generally detected at birth, nanocephalous disease often happens once there may be a problem with brain development within the uterus or when the brain stops growing at birth. nanocephalous are often caused by a range of genetic and environmental factors. Kids with microcephaly often have biological process issues. Though there' no treatment for microcephaly, early intervention with speech, activity and other confirmatory therapies might enhance a child's development and improve quality of life.
Microcephaly is a rare disorder in which the circumference of the head is smaller than normal because the brain has not developed properly or has stopped growing Most babies with microcephaly are born without any signs but some have an abnormally small head an unusually large forehead developmental delays and epilepsy (seizures) There is currently no known cure for microcephaly Treatment focuses on managing symptoms to improve quality of life.
Microcephaly is when a baby or child's head is much smaller than expected. This can happen because of birth defects (congenital) genetic problems, developmental delay or brain damage that happened after birth Microcephaly can cause serious health and development problems.
Symptoms Microcephaly
The primary symptom of abnormality is a head size that's a lot tinier than that of different children of an equivalent age and sex. Head size could be a live of the gap round the high of the child' head (circumference). exploitation standardized growth charts, health care suppliers compare the activity with other children' measurements in percentiles. Some children simply have small heads, with a measurement that falls below a longtime price for kids of the same age and sex. In children with microcephaly, head size measures much smaller than average for the child' age and sex. a baby with more-severe abnormalcy might also have a sloping forehead. apart from a perceptibly smaller head, the subsequent are the foremost common symptoms of microcephaly:
A high-pitched cry
Feeding problems
Hearing and vision problems
Convulsions (seizures)
Increased movement of the arms and legs (spasticity)
Hyperactivity (overly active)
Developmental delays, or problems learning how to speak, stand and walk
Intellectual disabilities (trouble with learning)
As the kid grows older, his or her face continues to grow whereas the os will not. This causes the child to develop an oversized face, a receding forehead and a loose, often wrinkled scalp.

Craniosynostosis (kray-nee-o-sin-cos-TOE-sis). Early fusing of the joints (sutures) between the bony plates that kind associate baby' os keeps the brain from growing. Treating craniosynostosis sometimes means that an infant wants surgery to separate the amalgamated bones. This surgery relieves pressure on the brain, giving it enough house to grow and develop.
Genetic changes. Down syndrome and other conditions may result in microcephaly.
Decreased oxygen to the fetal brain (cerebral anoxia). Certain complications of pregnancy or delivery can impair oxygen delivery to a baby's brain.
Infections passed to the fetus during pregnancy. These include toxoplasmosis, cytomegalovirus, German measles (rubella), chickenpox (varicella) and Zika virus.
Exposure to drugs, alcohol or certain toxic chemicals in the womb. Any of these may affect fetal brain development during pregnancy.
Severe malnutrition. Not getting enough nutrients during pregnancy may hurt fetal brain development.
Uncontrolled phenylketonuria (fen-ul-kee-toe-NU-ree-uh), also known as PKU, in the mother. PKU hampers the mother' ability to interrupt down the organic compound essential amino acid and will have an effect on brain development of the craniate throughout pregnancy.
Complications Microcephaly
Some kids with microcephaly come through organic process milestones albeit their heads can continually be little for his or her age and sex. however looking on the cause and severity of the microcephaly, complications might include:
Developmental delays, including speech and movement
Difficulties with coordination and balance
Dwarfism or short stature
Facial distortions
Hyperactivity
Intellectual delays
Seizures
Can a child with microcephaly be normal?
The medical term microcephaly refers to a condition in which the head is smaller than normal when compared to age- and sex-matched peers It is a nonprogressive disorder called primary microcephaly and occurs when there are insufficient fetal brain cells during the first two months after conception resulting in an abnormally small head In some cases parents may also give birth to a stillborn baby or newborn with microcephaly However only if the surviving baby lives longer than 6 months can it be diagnosed as secondary microcephaly (Source: Dr Richard Warshak www.drdickw.

How can you prevent microcephaly?
Microcephaly is the most common birth defect associated with Zika virus It occurs when babies are born with abnormally small heads which can cause delayed development of motor functions and intellectual disabilities However to date there have been no reported cases of microcephaly in America due to exposure to Zika virus The CDC recommends several ways to minimize mosquito bites: wear long-sleeved shirts and pants; use insect repellent containing DEET; spray insect repellent on your hands and then apply it to your face; avoid areas where mosquitoes congregate such as standing water or man-made containers that can retain water.

Once the baby is born, abnormalities are often diagnosed by measuring the baby’s head circumference (all the approach around) and comparing it with traditional head sizes of newborns. The doctor will perform an entire physical examination and procure a complete prenatal and birth history of the child. The doctor would possibly raise the elders concerning biological process milestones such as travel and walking, since abnormality is commonly among intellectual disabilities. to work out if your kid has microcephaly, your supplier possibly can take a radical prenatal, birth and case history and do a physical exam.
