I have gotten the chance to see many individuals involved in the program. A lot of the Best Buddies community show signs of diagnosis of Down syndrome, prompting this week's disorder. What is down syndrome?Down syndrome is the most common genetic chromosomal disorder, and it is caused by a chromosome mutation. This happens when atypical cell division occurs on chromosome 21. This disorder ranges in severity and is linked to both intellectual and developmental deficits. signsSome common symptoms include:
What causes it?The average human cell is made up of 23 chromosomes, half come from one’s mother and the other half come from the father. Down syndrome occurs when there is a mutation during cell division, specifically involving chromosome 21, which results in an extra full or partial chromosome 21. Different variations of this can occur including:
the brain & Down SyndromeThose with Down syndrome usually develop at a slower rate physically and also struggle intellectually. Research found that chromosome 21 interferes with learning and memory areas of the brain in those with Down syndrome. This was specifically seen in the hippocampus of the brain, which is a key area for memory storage and learning. Learning language and basic tasks strongly relies on recalling them. If the main area that stores memories in the brain is compromised, then learning for an individual can be very difficult and frustrating. take away 🎈Down syndrome is the most common genetic chromosome related disorder and is caused when chromosome 21 does not form typically. Some signs of Down syndrome generally involve a slower development of physical features as well as slower learning. Although Down syndrome is a disorder due to chromosome mutation, an atypical formation linked to chromosome 21 is shown to inhibit the hippocampus. This can cause individuals with Down syndrome to struggle with memory as well as learning. links
