March is Developmental Disabilities Awareness Month and we have put together some of the things we feel that you should know about Developmental disabilities.
What are Developmental Disabilities?
These are a group of conditions due to an impairment in physical, learning, language, or behavior areas. These conditions begin during the developmental period, may impact day-to-day functioning, and usually last throughout a person’s lifetime.
What are Developmental Milestones?
Skills such as taking the first step, smiling for the first time, and waving “bye-bye” are called developmental milestones. Children reach milestones in how they play, learn, speak, behave, and move (for example, crawling and walking). Children develop at their own pace, so it’s impossible to tell exactly when a child will learn a given skill. However, the developmental milestones give a general idea of the changes to expect as a child gets older.
As a parent, you know your child best. If your child is not meeting the milestones for his or her age, or if you think there could be a problem with the way your child plays, learns, speaks, acts, and moves talk to your child’s doctor and share your concerns. Don’t wait. Acting early can make a real difference!
Developmental Monitoring and Screening
A child’s growth and development are followed through a partnership between parents and health care professionals. At each well-child visit, the doctor looks for developmental delays or problems and talks with the parents about any concerns the parents might have. This is called developmental monitoring.
Any problems noticed during developmental monitoring should be followed up with developmental screening. Developmental screening is a short test to tell if a child is learning basic skills when he or she should, or if there are delays.
Causes and Risk Factors
Developmental disabilities begin at any time during the developmental period and usually last throughout a person’s lifetime. Most developmental disabilities begin before a baby is born, but some can happen after birth because of injury, infection, or other factors. Most developmental disabilities are thought to be caused by a complex mix of factors.
These factors include:
- Genetics; parental health and behaviors (such as smoking and drinking) during pregnancy.
- Complications during birth; infections the mother might have during pregnancy or the baby might have very early in life; and exposure of the mother or child to high levels of environmental toxins, such as lead.
For some developmental disabilities, such as fetal alcohol syndrome, which is caused by drinking alcohol during pregnancy, we know the cause. But for most, we don’t.
The following are some examples of what we know about specific developmental disabilities:
At least 25% of hearing loss among babies is due to maternal infections during pregnancy, such as cytomegalovirus (CMV) infection; complications after birth; and head trauma.
Some of the most common known causes of intellectual disability include fetal alcohol syndrome; genetic and chromosomal conditions, such as Down syndrome and fragile X syndrome; and certain infections during pregnancy.
Children who have a sibling with autism are at a higher risk of also having autism spectrum disorder.
Low birth weight, premature birth, multiple birth, and infections during pregnancy are associated with an increased risk for many developmental disabilities.
Untreated newborn jaundice (high levels of bilirubin in the blood during the first few days after birth) can cause a type of brain damage known as kernicterus. Children with kernicterus are more likely to have cerebral palsy, hearing and vision problems, and problems with their teeth. Early detection and treatment of newborn jaundice can prevent kernicterus.
Who Is Affected by Developmental Disabilities?
Developmental disabilities occur among all racial, ethnic, and socio-economic groups. Recent estimates in the United States show that about one in six, or about 17%, of children aged 3 through 17 years have one or more developmental disabilities, such as:
- Autism spectrum disorder
- Cerebral palsy
- Hearing loss
- Intellectual disability
- Learning disability
- Vision impairment and other developmental delays.
Living With a Developmental Disability
Children and adults with disabilities need health care and health programs for the same reasons anyone else does—to stay well, active, and a part of the community. Having a disability does not mean a person is not healthy or that he or she cannot be healthy. Being healthy means the same thing for all of us—getting and staying well so we can lead full, active lives. That includes having the tools and information to make healthy choices and knowing how to prevent illness.
Some health conditions, such as asthma, gastrointestinal symptoms, eczema and skin allergies, and migraine headaches, have been found to be more common among children with developmental disabilities. Thus, it is especially important for children with developmental disabilities to see a health care provider regularly.
