Microcephaly [edit on Wikidata] Microcephaly is a medical condition in which the brain does not develop properly resulting in a smaller than normal head. Microcephaly may be present at birth or it may develop in the first few years of life. Often people with the disorder have an intellectual disability, poor motor function, poor speech, abnormal facial features, seizures, and dwarfism.

Function i Microcephaly 5, primary, autosomal recessive (MCPH5). The disease is caused by mutations affecting the gene represented in this entry. Disease description A disease defined as a head circumference more than 3 standard deviations below the age-related mean.Brain weight is markedly reduced and the cerebral cortex is disproportionately small.Despite this marked reduction in size, the gyral pattern is relatively well preserved, with no major abnormality in cortical architecture. Affected individuals are mentally retarded.he disease is caused by mutations affecting the gene represented in this entry. Disease description A disease defined as a head circumference more than 3 standard deviations below the age-related mean.

Commonly Missed Diagnoses in the Childhood Eye Examination Amblyopia (lazy eye) is defined as a reduction in best-corrected visual acuity that is not directly attributable to any structural abnormality of the eye or visual pathway. With a prevalence of 2 percent,6 it is the most common cause of uncorrectable loss of vision in children. The visual outcome can range from 20/25, or nearly normal, to worse than 20/200, or legally blind. With effective detection and early treatment, most vision loss associated with this condition can be avoided.

Microcephaly The disorder may stem from a wide variety of conditions that cause abnormal growth of the brain, or from syndromes associated with chromosomal abnormalities. A homozygous mutation in one of the microcephalin genes causes primary microcephaly. In general, life expectancy for individuals with microcephaly is reduced and the prognosis for normal brain function is poor. The prognosis varies depending on the presence of associated abnormalities.

Microcephaly Microcephaly is a condition in which a person's head size is much smaller than that of others of the same age and sex. Head size is measured as the distance around the top of the head. A smaller than normal size is determined using standardized charts.

Overview Anencephaly is a serious developmental defect of the central nervous system in which the brain and cranial vault are grossly malformed. The cerebrum and cerebellum are reduced or absent, but the hindbrain is present. Anencephaly is a part of the neural tube defect (NTD) spectrum. This defect results when the neural tube fails to close during the third to fourth weeks of development, leading to fetal loss, stillbirth, or neonatal death.

Anencephaly Anencephaly can often be diagnosed before birth through an ultrasound examination. The maternal serum alpha-fetoprotein (AFP screening) and detailed fetal ultrasound can be useful for screening for neural tube defects such as spina bifida or anencephaly.
