Which physical characteristic is most indicative of an individual with Down syndrome?

Down syndrome is usually identified at birth by the presence of certain physical traits: low muscle tone, a single deep crease across the palm of the hand, a slightly flattened facial profile, and an upward slant to the eyes.

What are the physical characteristics of a person with Down syndrome?

Some common physical features of Down syndrome include: A flattened face, especially the bridge of the nose. Almond-shaped eyes that slant up. A short neck.

What are the physical characteristics of a child with Down syndrome?

Short neck, with excess skin at the back of the neck. Flattened facial profile and nose. Small head, ears, and mouth. Upward slanting eyes, often with a skin fold that comes out from the upper eyelid and covers the inner corner of the eye.

What are characteristic symptoms of Down syndrome?

How does Down syndrome affect physically?

Children with Down Syndrome tend to have quite floppy muscles (hypotonia or low muscle tone). This makes it harder for them to move and can affect all aspects of their physical development.

Down syndrome (trisomy 21) - causes, symptoms, diagnosis,

What are the early signs of Down syndrome in babies?

On an ultrasound (an image of a developing fetus, also called a sonogram), visible signs a baby may have Down syndrome include: Excess skin in the back of the neck (nuchal translucency) A shorter-than-normal femur (thigh) bone. A missing nose bone.

How does Down syndrome affect physical development in adults?

Adults with DS are at age-related increased risk for dementia, skin and hair changes, early onset menopause, visual and hearing impairments, adult onset seizure disorder, thyroid dysfunction, diabetes, obesity, sleep apnea and musculoskeletal problems.

Which of the following terms can be used to describe Down syndrome?

Down syndrome, also called Down's syndrome, trisomy 21, or (formerly) mongolism, congenital disorder caused by the presence in the human genome of extra genetic material from chromosome 21.

What are the cognitive characteristics of a person with Down syndrome?

A specific cognitive profile has been associated with the syndrome, individuals with DS being most likely to have more pronounced language and verbal memory challenges, and relatively stronger non-verbal abilities and implicit memory skills^3,4.

Which of the following oral features are frequently associated with Down syndrome?

People with Down syndrome may have large tongues or they may have an average size tongue and a small upper jaw that makes their tongue too large for their mouth. It is also common for people with Down syndrome to have grooves and fissures on their tongues.

Is Down syndrome a physical disability?

Down's syndrome is the commonest identifiable cause of intellectual disability, accounting for around 15-20% of the intellectually disabled population. It is believed that people with Down's syndrome have always existed.

Does Down syndrome always affect appearance?

It varies, but people with Down syndrome often share certain physical traits. For facial features, they may have: Eyes shaped like almonds (may be shaped in a way that's not typical for their ethnic group) Flatter faces, especially the nose.

How Down syndrome affects the physical and cognitive development?

Characteristic difficulties

Motor skills develop at a slower rate for children with Down syndrome than for those without. These delays in motor development reduce infants' opportunities for exploring and learning about the world around them and therefore further affect cognitive development.

Which of the following terms can be used to describe Down syndrome quizlet?

T/F In order to create the possibility of generating a trisomy, nondisjunction must occur during meiosis II. The incidence of Down syndrome, also known as trisomy 21, increases with increasing maternal age.

What is true about Down syndrome?

Also known as Down syndrome, trisomy 21 is a genetic condition caused by an extra chromosome. Most babies inherit 23 chromosomes from each parent, for a total of 46 chromosomes. Babies with Down syndrome however, end up with three chromosomes at position 21, instead of the usual pair.

How is Down syndrome defined?

Listen to pronunciation. (...SIN-drome) A genetic condition caused by having an extra chromosome 21 in some or all of the body's cells. Down syndrome is marked by growth, developmental, and learning delays that vary from mild to severe.

Which condition do older adults with Down syndrome tend to develop?

Many but not all people with Down syndrome develop Alzheimer's disease when they get older. People with Down syndrome are born with an extra copy of chromosome 21, which carries a gene that produces a specific protein called amyloid precursor protein (APP).

How does Down syndrome affect a child's growth and development?

Down syndrome is a genetic condition that happens when a child is born with an extra chromosome. The extra chromosome affects the way the child's brain and body develop, leading to developmental delays, intellectual disability and an increased risk for certain medical issues.

What are the causes of Down syndrome?

Down syndrome is usually caused by an error in cell division called “nondisjunction.” Nondisjunction results in an embryo with three copies of chromosome 21 instead of the usual two. Prior to or at conception, a pair of 21st chromosomes in either the sperm or the egg fails to separate.

Which of the following assessment findings would lead the nurse to suspect Down syndrome in an infant?

Which of the following assessment findings would lead the nurse to suspect Down syndrome in an infant? 1. Answer: A. Transverse palmar crease.

What makes a Down syndrome learner unique?

Down Syndrome Learning Strengths

Some of the specific learning strengths that characterize many children with Down syndrome include: A distinct preference for visual learning. High capacity for empathy and social understanding. Strong visual short-term memory.

Why do Down syndrome stick out tongue?

Some babies have decreased muscle tone. Since the tongue is a muscle, and is controlled by other muscles in the mouth, decreased muscle tone can cause the tongue to stick out more than usual. Several conditions may cause decreased muscle tone, such as Down syndrome, DiGeorge syndrome, and cerebral palsy.

What causes the facial features of Down syndrome?

The most common live-born human aneuploidy is trisomy 21, which causes Down syndrome (DS). Dosage imbalance of genes on chromosome 21 (Hsa21) affects complex gene-regulatory interactions and alters development to produce a wide range of phenotypes, including characteristic facial dysmorphology.

What is physical disability?

Physical disability indicates any physical limitations or disabilities that inhibit the physical function of one or more limbs of a certain person. It can be temporary or permanent. The causes of this kind of disease are various.

How is the Down syndrome diagnosed?

Diagnostic Tests. Amniocentesis, chorionic villus sampling (CVS) and ultrasound are the three primary procedures for diagnostic testing. Amniocentesis — Amniocentesis is used most commonly to identify chromosomal problems such as Down syndrome.
