Anencephaly is the absence of a major portion of the brain, skull, and scalp that occurs during embryonic development. [1] It is a cephalic disorder that results from a neural tube defect that occurs when the rostral (head) end of the neural tube fails to close, usually between the 23rd and 26th day following conception.

Stephanie Keene [1] was born at Fairfax Hospital in Falls Church, Virginia, a hospital in the Washington metropolitan area.At the time of her birth, she was missing most of her brain, including the cortex; only the brainstem, the portion of the brain responsible for autonomic and regulatory functions, such as the control of respiration, the heartbeat and blood pressure, had developed.
Anencephaly (without brain) is a severe neural tube defect that occurs when the anterior-most end of the neural tube fails to close, usually during the 23rd and 26th days of pregnancy. This results in an absence of a major portion of the brain and skull.
They told them the baby had anencephaly, which means she was missing parts of her skull and brain. Last Wednesday, they went to the University of Kentucky medical center, where doctors confirmed ...
Because the neural tube gives rise to the brain and spinal cord any mutations at this stage in development can lead to fatal deformities like anencephaly or lifelong disabilities like spina bifida. During this time, the walls of the neural tube contain neural stem cells , which drive brain growth as they divide many times.
The study was focused on analyzing tau, a protein in the brain that plays a key role in Alzheimer's. In people with the neurological disease, tau proteins undergo chemical changes, forming tangled ...
As Alzheimer’s disease is the most common form of dementia — affecting an estimated 6.7 million Americans — it’s not surprising that people who experience memory loss may suspect AD.. In ...
