â€œAnencephaly is a congenital anomaly characterized by an open neural tube in the cephalic region with an exposed mass of degenerate neural tissue on the skull floorâ€ (Cohen, C et al. 2001, p.704). It results when neural tube fails to come into contact during the first few days of embryogenesis. Anencephaly leads to alteration of the normal behavior of an individual. It alters with the normal reasoning, hearing, and movement coordination of an individual. This paper aims at providing detailed information on possible causes of anencephaly, its signs and symptoms, treatments, and prognosis.

Thus, individuals suffering from anencephaly lack cerebrum and cerebellum which constitute the largest portion of human brain. Neural tube is the main element of central nervous system of an embryo. Since anencephaly roots itself from the complications of the neural tube, it is justifiable to classify it also as a neural tube defect. Individuals suffering from this disease also lack some bones of the skull (Cohen, et al. 2001).

In some cases, thin layers of squamous epithelium may also be present. Although the cer...
