Down syndrome is a genetic disorder that involves an extra chromosome.
The healthcare needs of children with Down syndrome are better understood than ever before. Much can be done to prevent and treat medical problems that go along with Down syndrome.
Although children with Down syndrome may be slow in their achievements and must cope with their limitations, most lead productive, fulfilling lives. You can help your child reach his or her potential by making sure your child has regular checkups and gets proper therapy and medical treatment.
People normally have a total of 46 chromosomes. Most children with Down syndrome have a total of 47 chromosomes. Down syndrome results from this extra genetic material. Scientists are still learning about what causes this extra genetic material and exactly how it causes the problems of Down syndrome.
The chance of having a baby with Down syndrome increases as parents get older. The chance of having a Down syndrome baby goes up quickly when the mother is 35 years of age or older.
Down syndrome may be diagnosed before birth, or shortly after birth during a baby's first physical exam.
The diagnosis before birth may be based on:
The diagnosis after birth is usually based on how the child looks. The diagnosis is confirmed by a blood test on the baby that checks the baby’s chromosomes.
Growth and development is unique to every child. Children learn to walk, run, use their hands and eyes, understand language, speak, think, and solve problems at different rates. Children with Down syndrome do all of these things too. However, children with Down syndrome generally grow more slowly, learn more slowly, and have more trouble with reasoning and judgment than other children.
Specific growth and developmental milestones for children with Down syndrome have been developed.
As your child reaches adolescence, he or she will become more aware of his or her limitations. Emotional problems sometimes occur at this age. Your child may need extra help learning how to control sexual impulses. Doctors believe that a child's emotional health is best supported by staying involved in home, school, and community activities.
Children with Down syndrome usually have many health problems. Some have a heart problem at birth or later in life. As your child grows older, he may have vision, hearing, bone, joint, hormone, or dental problems. Because of these problems, a child with Down syndrome needs more medical and dental care and educational help to reach his or her full potential.
Breast-feeding a baby with Down syndrome is usually successful and helps the baby's ability to fight infection.
Children with Down syndrome tend to have a small mouth and a large tongue. This may cause spilling of liquids out of the side of the mouth. This problem usually goes away during infancy as tongue control improves. You may be taught special feeding techniques before you take your baby home.
Because many children with Down syndrome are born with heart defects, your child should be checked by a pediatric cardiologist soon after birth. A test called an echocardiogram, which uses sound waves to create a picture of the heart, is used.
Babies in nearly all states are tested in the hospital shortly after birth for low thyroid hormone levels. This is usually one of several tests known as the "newborn screen." Children with Down syndrome sometimes have low thyroid hormone levels.
Thyroid screening tests should be repeated for children with Down syndrome at 6 months, 12 months, and then each year after that.
Many children with Down syndrome have hearing problems. Often this is due to frequent ear infections or fluid in the middle ear. There may be other reasons for poor hearing. Hearing problems may come and go or always be present. Any cause of hearing loss should be treated by your doctor. Good hearing helps with language development.
7 of every 10 children with Down syndrome will need glasses. Around 20% of children with Down syndrome have eyes that point in slightly different directions. This needs to be treated. Most children with Down syndrome need to see an eye doctor at about one year of age.
The teeth of a child with Down syndrome usually come in later than the teeth of most children. The first tooth usually appears between 12 and 48 months. Fifty percent of children with Down syndrome are missing one or more teeth.
Teeth often will not be in the best position for chewing. For example, a child may have an overbite (the upper teeth coming out forward) or a crossbite (the lower teeth set to one side of the upper teeth). Gum disease is more common in children with Down syndrome.
Children with heart defects who are going to have dental work done often need antibiotic medicine before the procedure.
Air passages in the nose, mouth, and chest are smaller than in children without Down syndrome. As a result of the narrowing, a number of problems can occur. Mouth breathing may develop and this can lead to teeth problems. Snoring may be a sign of a narrowed airway. Narrowing may become so severe that the airway becomes blocked, causing air flow to stop. This problem is known as sleep apnea.
Check with your doctor if your child snores a lot, especially if they have loud snoring, followed by silence, a snort, partial awakening, and then snore again.
Between the ages of 3 and 5 years, all children with Down syndrome should have X-rays of the upper spine. The X-rays are taken to look for too much movement of the bones in the upper spine when the neck is held in different positions.
Dislocation, or slippage, of the bones in the upper spine is not common but can result in serious injury. Usually, the child would have several weeks of symptoms before this happened. Symptoms would include: neck pain, head tilt, breathing changes, weakness, or changes in walking ability. If your child has these symptoms, tell your doctor so the spine can be checked. A careful neck exam is important before your child plays in sports.
Ignore outbursts unless your child is destructive. Then use time outs or mild physical restraint until he is calm. Reward your child for times when outbursts don't occur. Ask about local Down syndrome support groups where parents can share ideas and experiences.
Teach your child to not stare at others, make sexual comments, or touch their private parts in public.
Help your child deal with his frustration. Suggest other activities that your child can do. Behavioral training programs may help your child learn how to respond calmly and appropriately.
Children with Down syndrome tend to become dependent on others and need experiences that encourage independence.
You will probably hear of many treatments for children with Down syndrome. They may range from megavitamin therapy to facial surgery. Many of these treatments are unproven and some may be harmful. Check with your child's doctor before trying any treatment.
Get therapy and other services started when your child is young. Government programs are available for children starting at birth. This will help your child reach his or her greatest potential.
The professionals who can provide services include:
Often mental health specialists can help design behavioral training programs. For emotional and behavioral problems, medicines may help control moods and inappropriate behavior.
