Not only does the global community celebrate Down’s syndrome, the day allows focus on a particular issue.

This year, the global theme is “Leave no one behind”

All people with Down syndrome must have opportunities to live fulfilling lives, included on a full and equal basis with others, in all aspects of society.

There will be special events at the UN in New York and Geneva and the DSA will be joining the DSi and other organisations, families and communities around the world to say that society needs to make sure that we #LeaveNoOneBehind.

It is generally accepted that both Down’s syndrome and Down syndrome can be used interchangeably. For us at the Down’s Syndrome Association, the most important thing is the use of person first terminology (e.g. “person with Down’s syndrome“, not “Down’s syndrome person“). The use of the possessive apostrophe is a recognised model that is used for a number of conditions in Britain, thus, in the UK Down’s syndrome is used more commonly, whereas in other countries the more prominent is Down syndrome.
