Of every 800 to 1000 babies that are born, one is diagnosed with Down syndrome. Older women have a higher chance of having a baby with Down syndrome. If they have a procedure known as amniocentesis, pregnant mothers can be told whether their foetus has Down syndrome. Sound scans may also diagnose the presence of Down Syndrome. Mothers whose foetus is diagnosed as having Downs syndrome may choose to have an abortion. In the United Kingdom and Europe 92% of such cases are aborted.
