World Down Syndrome 1 Day is on March the 21st every year. It is on this day because the number 21 is important in the identification of Down Syndrome. The condition is created by a 21st, extra chromosome 2 being replicated 3 three times, thus causing the condition. The day is organized by Down Syndrome International (DSI), which runs different annual campaigns. DSI aims to create global awareness 4 about Down Syndrome and encourage countries to help sufferers play a bigger role in their societies. DSI says sufferers are able to make significant contributions to society. Down Syndrome is common throughout the world. Estimates are that the incidence of the condition is over 1 per 1,000 births.


Down Syndrome is a disorder 5 of the chromosomes 6. Most people have 20 chromosomes, but the presence of an extra 21st chromosome creates the disorder. It is named after the British doctor, John Langdon Down, who first described the syndrome in 1866. Sufferers experience a limitation in their cognitive 7 ability and physical growth, as well as changes in their facial appearance. People with Down Syndrome range from having slight developmental disabilities to very serious mental disability. Down Syndrome also increases the risk of heart defects, kidney disease and insomnia 8. Nowadays, loving care and good education can provide sufferers with a good quality of life and enable them to make valuable contributions to their fields of work.
