Definitions for "NTD"
Neural Tube Defects, also known as Spina Bifida.
NEURAL TUBE DEFECTS. an abnormality of the spinal cord or brain
NEURAL TUBE DEFECT. An abnormality where the spine has not closed over the central nervous tissue. If this 'lesion' is at the head, the condition is called anencephaly and is incompatible with life. If it occurs anywhere lower down the spine it is called spina bifida and results in varying degrees of physical and mental disability. Detailed ultrasound scanning is the way in which these abnormalities are confirmed, often following a raised AFP blood test. Most NTDs are 'open' which means that there is no skin over the lesion in the spine; about 1 in 7 cases of spina bifida are 'closed' which means that although the spine has not covered the nervous tissue there is a covering of skin. These closed conditions are less likely to be detected antenatally by the AFP test.
Neon Tetra Disease. A parasitic disease with a high mortality rate and no known cure. Although first noticed in Neons, many fish are susceptible to one degree or another.
