World Down Syndrome Day

World Down Syndrome Day is an international holiday dedicated to increasing public awareness of Down syndrome. It is celebrated annually on March 21. This disease is genetic, and it is impossible to get rid of it. However, it is in our power to make sure that the person grows and develops normally, and does not feel superfluous in society because of his defect.


The history of World Down Syndrome Day begins in 2005, when it was first celebrated. Numerous medical organizations, including those assisting people with Down syndrome, became involved in the day.

Historical evidence proves the presence of Down syndrome in ancient times. However, at that time children with disabilities were often killed because they were incapable of living a normal life. In any case, people with Down syndrome lived very short lives because they were predisposed to various diseases.

Down syndrome was first defined as a form of mental retardation in 1826. John L. Down, the doctor whose last name gave the disease its name, did the research. During the formation of the fetus in the womb, the 21st chromosome is tripled. However, the exact factors leading to the genetic malfunction have never been identified.

The growth of the movement of advocates for the protection and care of people with Down syndrome began in the 1950s. The first associations that raised the issue in society began to be formed. In today’s world, such people can get qualified help. Thanks to medicine, it is possible to give patients a normal life, although many signs of the syndrome will remain in them for life.
