Down Syndrome-Symptoms, Causes, Treatment, Pictures

 

Down syndrome is a hereditary disorder that may lead to life long deceleration of mental abilities, developmental delay and other physical issues. This condition varies in terms of severity, which is why development issues may range from moderate to severe. The syndrome is considered as one of the most common factors resulting in learning disabilities in children. It is believed that diagnosing and understanding the prevalence of the syndrome may make a big different in the physical abilities of the affected child as well as adults.

Symptoms of Down syndrome

Children afflicted with Down syndrome have anomalous facial features or appearance. However, not all of them may have noticeable facial irregularity. Here are some signs of the condition related to facial appearance.

• Flattened features of the face

• Protruding tongue

• Comparatively shorter neck

• Smaller head as compared to face

• Slightly upwards leaning eyes

• Unusually shaped or deformed ears

 

Other symptoms of Down Syndrome

• Poor residual muscles tension or poor muscles tone

• Broader and usually shorter palm with lesser or single crease

• Comparatively shorter fingers

• Flexibility to excessive extent

Infants with Down syndrome may be born in average size; however, their growth rate remains slow which makes them shorter as compared to other children of same age. For a child with this condition it takes double the time for walking and crawling as compared to a normal child. Most affected children also face mental retardation to certain extent, usually mild to moderate level.

Causes of Down syndrome:

Defects in chromosome is believed to be the chief cause of Down syndrome. It is studied that normally human cells contains chromosomes in pairs and there are 23 such pairs. Each pair of chromosome comes from is contributed by both mother and father, one comes from paternal side and the other from maternal side. When any one of the 3 cell division irregularity occurs related to chromosome 21, it may result in Down syndrome. In case all 3 cell division abnormality of chromosome 21 occurs it may cause issues related to development as well as characteristic features of this condition.

Trisomy 21:

Trisomy 21 is considered as a common factors causing Down syndrome as over 90 percent of cases are attributed to this particular cause. In this case an affected child carries 3 copies of chromosome 21 in all his cells rather than two copies as in normal cases. This factor causes anomalous cell divisions at the time of development of spermatozoan cell or cells of egg.

Mosaic Down syndrome:

This is a rare kind of Down syndrome. In this type of condition affected children have some cell containing additional copy of chromosome 21. This assortment of normal or anomalous cell is resulted by abnormal division of cell post fertilization.

Translocation Down syndrome:

The condition may also result if portion of chromosome 21 becomes translocated or attached to another chromosome during or prior to conception. Children affected with such kind of condition carries conventional two copies of chromosome 21 but they may also contain extra material this chromosome which is attached to the translocated chromosome. This is an uncommon kind of Down syndrome.

Most people may link the condition with some other causes. It should be known that there are no environmental or behavioral factors that may lead to such condition. The above mentioned are few causes understood by the medical industry. In most cases the condition may not be genetic, in fact it can be said that the syndrome is caused by mistake related to cell division during developmental stage of spermatozoa, egg or embryo. However, translocation type syndrome is the only kind of Down disorder which cab be inherited. Nevertheless even this condition is rare as only 4 percent of all Down syndrome cases are attributed to translocation of chromosomes. Out of this four percent only half of the affected children inherit the condition from one of their parents. If the father is carrier then there are 3 percent chances of the child being affected with the condition. Whereas, if the mother is carrier then there are approx 10 to 15 percent chances that the child will suffer from translocation Down syndrome.

Team efforts:

Team efforts make it easy for your child to understand and learn better. The results obtained through team care are better than individual care. There is a team of specialist who will provide medical care to your child as well as try to develop physical skills as far as possible. Apart from the primary health care expert or pediatrician, the team of experts may include:

• Cardiologist

• Pediatric Gastroenterology expert

• Endocrinologist

• Pediatric Neurologist

• Developmental expert

• Audiologist

• Speech and language pathologist

• Occupational therapist also abbreviated as OT

• Physiotherapist also referred to as physical therapist

For a child affected with this syndrome, it may take double the time to learn walking, crawling etc. However, when early intervention program is adopted immediately, it may help your child to learn and grab things faster as compared to other child with same physical issues but not medical aid. Hence, timely diagnosis as well as early intervention plan may help your child lead a close- to- normal life even under prevalence of Down syndrome.
