The concept of life without a brain may seem unthinkable, but in the realm of medical conditions and abnormalities, it’s a harsh reality for some. Anencephaly is a congenital malformation that arises from an unfathomable complication during fetal development, leading to partial or total absence of the brain and skull. This article delves into this complex subject, examining its causes, diagnosis, implications on survival and quality of life, as well as presenting ethical dilemmas parents face when confronted with such a diagnosis.
Anencephaly: a Congenital Malformation Explained
Understanding Anencephaly
Anencephaly is a rare malformation of the central nervous system. It is characterized by partial or total absence of the brain and skull. This condition raises complex questions about life, birth, and the potential onset of human consciousness given its severe impact on normal brain functions.
The Formation Process
This congenital abnormality typically forms between the 20th and 28th day after conception when part of the neural tube fails to close. This failure impedes the development of vital structures like scalp, cranial vault, meninges, cerebral hemispheres, and cerebellum. Newborns with anencephaly usually have parts of the brainstem intact but lack structures responsible for life-sustaining functions such as reasoning abilities, awareness state and motor coordination.
Living up to its name derived from Greek roots meaning ‘without brain’, we now turn to examine what could possibly cause such an anomaly.
