Down syndrome,or Down’s syndrome (primarily in the United Kingdom),trisomy  21, or trisomy G, is a chromosomal disorder caused by the presence of all or part of an extra 21st chromosome. It is named after John Langdon Down, the British physician who described the syndrome in 1866.

The disorder was identified as a chromosome21 trisomy by Jérôme Lejeune  in 1959. The condition is characterized by a combination of major and minor differences in structure.

Often Down  syndrome is associated with some impairment of cognitive ability and physical growth, and a particular set of facial characteristics. Down syndrome in a fetus can be identified with  amniocentesis during pregnancy, or in a baby at birth.

Individuals with  Down syndrome tend to have a lower-than-average cognitive ability, often ranging from mild to moderate disabilities. A small number have severe to profound mental disability.

The average IQ of children with Down syndrome  is around 50, compared to normal children with an IQ of 100.The incidence  of Down syndrome is estimated at 1 per 800 to 1,000 births, although it is statistically much more common with older mothers. Other factors may also play a role.

Many of the common physical features of Down syndrome may also appear in people with a standard set of chromosomes, including  microgenia (an abnormally small chin),an unusually round face, macroglossia (protruding or oversized tongue), an almond shape to the eyes caused by an epicanthic  fold of the eyelid, upslanting palpebral fissures (the separation between the upper and lower eyelids), shorter limbs, a single transverse palmar crease (a single instead of a double crease across  one or both palms, also called the Simian crease), poor muscle tone, and a larger than normal space between the  big and second toes.

Health concerns for individuals  with Down syndrome include a higher risk for congenital heart defects, gastroesophageal Georgia Life Insurance reflux disease, recurrent ear infections, obstructive sleep apnea, and thyroid dysfunctions.

Early childhood intervention,  screening for common problems, medical treatment where indicated, a conducive family environment, and vocational training can improve the overall development of children with Down syndrome.

Although  some of the physical genetic limitations of Down syndrome cannot be overcome, education and proper care will improve quality of life.

Down syndrome can result from several different genetic mechanisms. This results in a widevariability in individual signs and symptoms  due to complex gene and environment interactions. Prior to birth, it is not possible to predict the symptoms that an individual with Down syndrome will develop.

Individuals with Down syndrome may have some or  all of the following physical characteristics: microgenia (abnormally small chin),oblique eye fissures with epicanthic skin folds on the inner corner of the eyes (formerly known as a mongoloid fold),muscle hypotonia (poor muscle tone), a flat nasal bridge, a single palmar fold, a protrudingtongue (due to small oral cavity, and an enlarged tongue near the tonsils) or macroglossia,a short neck, white spots on the iris known as Brushfield spots,excessive joint laxity including atlanto-axial instability, excessive space between large  toe and second toe, a single flexion furrow of the fifth finger, and a higher number of ulnar loop dermatoglyphs.

Most individuals with Down syndrome have mental retardation in the mild (IQ 50–70) to moderate (IQ 35–50) range,with individuals having Mosaic Down syndrome typically 10–30 points higher.They also may have a broad head and a very round face.

Language skills show a difference between understanding speech and expressing speech, and commonly individuals with Down syndrome have a speech delay.Fine motor skills are delayed and often lag behind gross motor skills and can interfere with cognitive development. On a totally differrent note ex is a great male supplement as is Effects of the disorder on the development of gross motor skills are quite variable.

Some children will begin walking at around 2 years of age, while others will not walk until  age 4. Physical therapy, and/or participation in a program of adapted physical education (APE), may promote enhanced development of gross motor skills in Down syndrome children.

Growth parameters such as height, weight, and head circumference are smaller in children with DS than with normal individuals of the same age. Adults with DS tend to have short stature —affiliate marketing the average height for men is 5 feet 1 inch (157 cm) and for women is four feet  9 inches (144 cm).Individuals with DS are also at increased risk for obesity as they age.

New data on Down syndrome

Figure: 40 % of children along with Down syndrome affliction have hereditary term life insurance with high blood pressure heart flaws.

That means 60% of kids born along with Down syndrome DON’T have any coronary heart defects whatsoever! Comparatively, within the general populace 1 from 120 infants life insurance diabetes have hereditary heart flaws. While the price of coronary heart defects is actually higher in youngsters with  Down syndrome , we must remember that  Down syndrome just occurs in one out of 733 births.

For each ONE kid ohio national life insurance company born along with Down affliction, there are Five children with out  Down syndrome born along with congenital coronary heart defects. Which means there are a LOT much more children with out Down syndrome affliction that have coronary heart defects compared to there are kids with Down syndrome affliction that have coronary heart defects. By the way – One’s heart defects present with infants created with Down syndrome tend to be, in the arena of heart flaws and their associated surgeries, effortlessly corrected.

Figure: The life expectations of people along with Down syndrome is Fifty five years, upward from Two-and-a-half decades in 1983.

We don’t know about you people, but I wish my children reside longer than Fifty five years. Nevertheless, statistically talking, that’s more than a 100% rise in life expectancy in under 30 years. And also the folks along with Down syndrome affliction who are residing to Fifty five years old these days were created in ’55.

Medical technology experienced just advanced enough to recognize the cause of Down syndrome because the triplication of the Twenty-first chromosome.  As such, infants could be identified at delivery but — given the world’s institutionalization attitude – infants were taken away “before their own parents might bond along with them”.

There was no considered family or even community addition.  No intervention from all… never mind earlier!  And, the majority of heart flaws still proceeded to go undetected and for that reason uncorrected. As a matter of reality, sadly, nicely into the 80′s, most babies born along with Down syndrome were still becoming institutionalized.

I couldn’t look for a statistic for that average life-span of someone along with Down syndrome affliction institutionalized for life however to give you a concept of how existence in and out of an organization compares: the typical post-paralysis lifespan of the quadriplegic living in a good institution these days is 1 . 5 years compared to a quadriplegic residing independently in whose average post-paralysis life-span is Fifteen years.

You get the idea! The actual lifespan of the individual along with Down syndrome affliction in 1929 (institutionalized) had been 9 years. Within 1983 it was Two-and-a-half decades (most likely institutionalized). This year it is 55+ (probably institutionalized for at least a part of their life). Who knows exactly what the future may bring… but with improvements in medication, quality associated with care as well as family as well as community addition to address the actual physical, psychological and emotional development of people with Down affliction, their life-span will quickly approach the typical lifespan for all those of us with out Down syndrome affliction.

Figure: The amount of births of babies with Down syndrome offers declined through 8 % since 1989, and also the number is anticipated to decline additional after a suggestion last year through the American University of Doctors and Gynecologists that mothers go through screening with regard to Down affliction.

I’m not sure in which the bright place is about this one. Reducing the incidence associated with Down syndrome affliction means a rise in selective end of contract (read: abortion) associated with fetus’ prenatally diagnosed with Lower syndrome. Is the fact that a good thing? We promise a person, many life – such as my own — have been significantly enhanced through the presence of individuals with Down syndrome.

As well as, if we’re ending children with Nintendo ds, should we terminate the actual 1 in A hundred and twenty “typically developing” babies created with coronary heart defects whilst we’re at it? In the end, the heart deficiency is often the cause sited through medical professionals with regard to terminating the actual fetus along with Down syndrome affliction. Often noticeable in utero, we’re able to rid the realm of everyone created without a ideal heart.
