Children reach developmental milestones at their own pace. Minor, temporary delays are usually no cause for alarm, but an ongoing delay or multiple delays in reaching milestones can be a sign there may be challenges later in life.
Delay in reaching language, thinking, and motor skills milestones is called developmental delay.
Developmental delay may be caused by a variety of factors, including heredity, problems with pregnancy, and premature birth. The cause isn’t always known.
If you suspect your child has developmental delay, speak with their pediatrician.
Developmental delay sometimes indicates an underlying condition that only doctors can diagnose. Early intervention will help your child’s progress and development into adulthood.
Fine motor skills include small movements like holding a toy or using a crayon. Gross motor skills require larger movements, like jumping, climbing stairs, or throwing a ball.
Children progress at different rates, but most children can
Exhibiting some of the following signs can mean that your child has delays in developing certain fine or gross motor functions:
- floppy or loose trunk and limbs
- stiff arms and legs
- limited movement in arms and legs
- inability to sit without support by 9 months old
- dominance of involuntary reflexes over voluntary movements
- inability to bear weight on legs and stand up by about 1 year old
Falling outside the normal range isn’t always cause for concern, but if your child is unable to perform tasks within the expected time frame, speak to your doctor.
According to the National Institute on Deafness and Other Communication Disorders (NIDCD), the most active time for learning speech and language is the first three years of life, as the brain develops and matures.
The language learning process begins when an infant communicates hunger by crying. By
Speech and language delay aren’t the same. Speaking requires the muscle coordination of the vocal tract, tongue, lips, and jaw to make sounds.
A speech delay occurs when children aren’t saying as many words as would be expected for their age.
A language delay occurs when children have difficulty understanding what other people say or can’t express their own thoughts. Language includes speaking, gesturing, signing, and writing.
It can be hard to distinguish between speech and language delay in young children. A child who understands things and can express their needs (maybe by pointing or signing) but isn’t speaking as many words as they should may have an isolated speech delay.
Poor hearing can cause speech and language delay, so your doctor will usually include a hearing test during diagnosis. Children with speech and language delay are often referred to a speech-language pathologist. Early intervention can be a big help.
Autism spectrum disorder (ASD) is a neurodevelopmental disorder that can impair your child’s ability to communicate and interact with others.
Classic ASD usually includes language delay and intellectual disabilities. Symptoms are sometimes obvious early on, but may not be noticed until a child reaches 2 or 3 years of age.
Signs and symptoms of ASD vary, but usually include delayed speech and language skills and difficulty communicating and interacting with others. Each child will have a unique pattern of behavior with differing levels of severity. Some symptoms include:
- failure to respond to their name
- resistance to cuddling or playing with others
- lack of facial expression
- inability to speak or difficulty speaking, carrying on a conversation, or remembering words and sentences
- repetitive movements
- development of specific routines
- coordination problems
There is currently no cure for ASD, but early intervention and education can help your child progress more fully.
According to the
Most developmental disabilities occur before a child is born, but some can occur after birth due to infection, injury, or other factors.
Causes of developmental delay can be difficult to pinpoint, and a variety of things can contribute to it. Some conditions are genetic in origin, such as Down syndrome. Infection or other problems during pregnancy and childbirth, as well as premature birth, can also cause developmental delay.
Developmental delay can also be a symptom of other underlying medical conditions, including:
- autism spectrum disorders (ASDs)
- cerebral palsy
- fetal alcohol spectrum disorders
- Landau Kleffner syndrome
- myopathies, including muscular dystrophies
- genetic disorders, such as Down syndrome and fragile X syndrome
Remember that children develop at different rates. However, if you think your child is developmentally delayed, talk to your doctor.
If your school-age child is diagnosed with developmental delay, you may be eligible for special services. Specialized services vary according to need and location.
Check with your physician and your school district to find out what services are available. Specialized education, especially when started early, can help your child progress and achieve more in school.
Treatments for developmental delays vary according to the specific delay. Some treatments include physical therapy for help in motor skill delays, and behavioral and educational therapy for help with ASD and other delays.
In some cases, medications may be prescribed. An evaluation and diagnosis from a pediatrician is crucial to come up with a treatment plan specially designed for your child.
Many genetic and environmental factors figure into a child’s development and can contribute to delays in their development. Even women who have a healthy pregnancy and proper care during and after pregnancy can have children with developmental delays.
Although causes of delays can be hard to pinpoint, there are many treatments and support services available to manage developmental delays. Be sure to speak to your doctor if you see your child exhibiting symptoms of developmental delays.
The sooner you can diagnose a delay, the better it will be for your child’s development into adulthood.
