October
is Down Syndrome Awareness Month, a chance to spread awareness. During
the month of October, we celebrate people with Down syndrome and make
people aware of our abilities and accomplishments. It’s not about
celebrating disabilities, it’s about celebrating abilities.
We can learn all about our history. We have a right to speak out about what it’s like to have Down syndrome and to learn the real story of people like us. People with Down syndrome and their loved ones can spread awareness about Down syndrome by going to their local Buddy Walk® and we can speak out about our needs. This is how we advocate. Our parents can teach us about education and how to advocate for ourselves – and give us love, support and encouragement.
Remember that this is a very important month – we have to spread awareness about Down syndrome and learn more about ourselves.

What Is Down Syndrome?
Down
syndrome (or Down's syndrome) is a chromosomal disorder caused by an error in cell
division that results in an extra 21st chromosome. The condition leads to
impairments in both cognitive ability and physical growth that range from mild
to moderate developmental disabilities. Through a series of screenings and
tests, Down syndrome can be detected before and after a baby is born.
The only factor known to affect the probability of having a baby with Down syndrome is maternal age. That is, less than one in 1,000 pregnancies for mothers less than 30 years of age results in a baby with Down syndrome. For mothers who are 44 years of age, about 1 in 35 pregnancies results in a baby with Down syndrome. Because younger women generally have more children, about 75 - 80% of children with Down syndrome are born to younger women.

What
causes Down syndrome?
Down syndrome occurs because of an
abnormality characterized by an extra copy of genetic material on all or part
of the 21st chromosome. Every cell in the body contains genes that are grouped
along chromosomes in the cell's nucleus or center. There are normally 46
chromosomes in each cell, 23 inherited from your mother and 23 from your
father. When some or all of a person's cells have an extra full or partial copy
of chromosome 21, the result is Down syndrome.
The most common form of Down syndrome is known as Trisomy 21, a condition where individuals have 47 chromosomes in each cell instead of 46. This is caused by an error in cell division called nondisjunction, which leaves a sperm or egg cell with an extra copy of chromosome 21 before or at conception. Trisomy 21 accounts for 95% of Down syndrome cases, with 88% originating from nondisjunction of the mother's egg cell.
The remaining 5% of Down syndrome cases are due to conditions called mosaicism and translocation. Mosaic Down syndrome results when some cells in the body are normal while others have Trisomy 21. Robertsonian translocation occurs when part of chromosome 21 breaks off during cell division and attaches to another chromosome (usually chromosome 14). The presence of this extra part of chromosome 21 causes Down some syndrome characteristics. Although a person with a translocation may appear physically normal, he or she has a greater risk of producing a child with an extra 21st chromosome.
