Down syndrome is not a disease, as many people believe today. It is a condition that occurs when a person is born with more than 46 chromosomes, which is common. Although it is not very clear why this extra chromosome is generated, it is believed that it is due to a process known as “trisomy 21”, and that is why month 3 and day 21 were chosen to celebrate Down Syndrome day. World Down Syndrome Day aims to ensure the right to equality, opportunity, and full happiness for people who have this condition, which causes incomplete development at the brain level. This Down Syndrome day, we must take advantage of the opportunity to celebrate life and diversity, understanding that it is very important to create a society where there is respect, tolerance, and acceptance towards all kinds of people.
