abnormally small cranium marked by premature fusion of the skull sutures and also underdeveloped brain.
Term used to describe a congenital birth defect that results in the baby having an unusually small head and some degree of mental retardation. A microcephalic head is more than two standard deviations below average circumference for age, sex, race and gestational age. Causes include an autosomal recessive disorder, chromosomal abnormality, or some toxic stimulus. Other causes include maternal infection or trauma, especially during the third trimester.
(mi·cro·ceph·a·ly) NOUN: Anomalous smallness of the head, usually accompanied by varying degrees of cogntive disability. People with microcephaly were popular in the freak shows of the late nineteenth and early twentieth centuries.

small head size in relation to the rest of the body; below the third percentile on growth charts.
Small size of the head in relation to the rest of the body. May result in developmental delay (especially in the areas of speech and motor skills), mental retardation or seizures.
An abnormally small cranium as a result of the premature closure of one or more fontanels.
A small skull with small cranial capacity. Microcephaly usually indicates that a baby will have learning or developmental disabilities.
abnormally small cranium typically associated with brain malfonnation
A small skull with small cranial capacity. Can indicate mental retardation.
A condition where the head is abnormally small.
The congenital smallness of the head, with corresponding smallness of the brain.
A small skull with small cranial capacity. Usually indicates mental retardation.
head circumference below normal for age (two standard deviations below the average); usually reflects lack of brain growth.
abnormal smallness of the head (often accompanied by microencephaly) that results in a lack of stimulus for the head vault to grow. Microcephalis children are usually mentally and developmentally retarded. Microcephaly can accompany various genetic syndromes, such as a chromosomal disorder.

a condition, present at birth, in which the head is much smaller than normal for an infant of that age and gender.
abnormal smallness of the head or brain case
Characterized by an exceptionally small head (head circumference is more than two standard deviations below the average size).
An abnormally small head.
A condition of abnormal smallness of the head, usually associated with mental defects.
Microcephaly is a neurological disorder in which the circumference of the head is significantly smaller than average for the person's age and sex. Microcephaly may be congenital or it may develop in the first few years of life. The disorder may stem from a wide variety of conditions that cause abnormal growth of the brain, or from syndromes associated with chromosomal abnormalities.
