World Down Syndrome Day: Down syndrome appears as a genetic disorder after unusual cellular division, resulting in either a complete or partial additional chromosome 21. The body and brain development process changes due to additional genetic materials, resulting in physical disability with cognitive difficulties.

Down syndrome stands as the most prevalent genetic disorder because the disease control and prevention center (CDC) indicates that it affects 1 in 5,700 newborns every 5,700 newborns in the United States. Research on the developmental effect of an additional chromosome 21 is necessary to develop better support systems that improve the quality of life of Down syndrome patients.

A developmental behavior, a pediatrician and a teenage mental health specialist. According to Himani Narula Khanna, the genetic base of the co-founder, the co-founder of the contenta kids, includes an additional copy of the chromosome 21, leading to significant developmental differences.

There are 46 chromosomes in a human body that are present in the pattern of 23 pairs. Chromosome is present with a third copy down syndrome of 21, resulting in 47 chromosomes in total. Dr. Khanna explains that Tricomy stands as the primary cause of 21 down syndrome as it affects about 95% of births. Additional genetic materials from chromosome 21 inhibit both biological processes and developmental routes.

She further states that individuals with Down syndrome sometimes present two rare adaptations of the situation: Mosaic Down syndrome appears when only a few body cells have an additional chromosome, while in translocation down syndrome, chromosome 21 combines with another chromosome.

How an additional chromosome affects the development of the brain

Dr. Khanna says that the additional chromosome 21 results in functional changes as well as the result of down syndrome in the brain structure. Research indicates that the down syndrome affects the measurement of the volume of the brain, including the learning and memory center of the hippocampus as well as the coordinated area of ​​the cerebellum.

Changes in the brain causes delay in cognitive function due to chromosomal differences and cause difficulties to learn together with problems in speech development. Dr. Khanna also suggests that people with down syndrome develop Alzheimer’s disease in life due to the app gene located on Chromosome 21, which triggers the formation of brain plaques.

Physical development of people with Down syndrome is negatively affected. Dr. Khanna says that Down syndrome causes individuals to display four specific physical characteristics that include a flat facilitated figure and a flat eye position with small nose structures and folds of a single hand palm. She says that due to down syndrome, individuals have less muscle tones, resulting in sitting, standing and learning to learn to walk for a long time. Children with down syndrome grow separately because they reach low heights than specific colleagues.

Dr. Khanna explains that down syndrome occurs when individuals inherit an additional third copy of chromosome 21, causing organizational problems in their brain and body. Additional chromosome 21 materials cause physical difference and development problems, yet proper medical attention combined with educational resources with medical practices helps to increase the quality of life for those affected.

Studies continue to search for new methods to help people with Down syndrome help to help develop better healthcare strategies. Increasing joint social awareness with better understanding will help in building a society that promotes success for people with Down syndrome.
