What Are Some Behavioral Challenges Typical In Persons with Down Syndrome?
The definition of a "behavior problem" varies but certain guidelines can be helpful in determining if a behavior has become significant.
- Does the behavior interfere with development and learning?
- Are the behaviors disruptive to the family, school or workplace?
- Is the behavior harmful to the child or adult with Down syndrome or to others?
- Is the behavior different from what might be typically displayed by someone of comparable developmental age?
The first step in evaluating a child or adult with Down syndrome who presents with a behavior concern is to determine if there are any acute or chronic medical problems related to the identified behavior. The following is a list of the more common medical problems that may be associated with behavior changes.
- Vision or hearing deficits
- Thyroid function
- Celiac disease
- Sleep apnea
- Gastroesophageal reflux
Evaluation by the primary care physician is an important component of the initial work-up for behavior problems in children or adults with Down syndrome.
The behavioral challenges seen in children with Down syndrome are usually not all that different from those seen in typically developing children. However, they may occur at a later age and last somewhat longer. For example, temper tantrums are typically common in 2-3 year olds, but for a child with Down syndrome, they may begin at 3-4.
When evaluating behavior in a child or adult with Down syndrome it is important to look at the behavior in the context of the individual's developmental age, not only his or her chronological age. It is also important to know the individual's receptive and expressive language skill levels, because many behavior problems are related to frustration with communication. Many times, behavior issues can be addressed by finding ways to help the person with Down syndrome communicate more effectively.
What Are Some of the Common Behavior Concerns?
The most important thing is the safety of the child. This would include good locks and door alarms at home and a plan written into the IEP at school regarding what each person's role would be in the event of the child leaving the classroom or playground. Visual supports such as a STOP sign on the door and/or siblings asking permission to go out the door can be a reminder to the child or adult with Down syndrome to ask permission before leaving the house.
A description of the child or adult's behavior during a typical day at home or school can sometimes help to identify an event that may have triggered non-compliant behavior. At times, oppositional behavior may be an individual's way of communicating frustration or a lack of understanding due to their communication/language problems. Children with Down syndrome are often very good at distracting parents or teachers when they are challenged with a difficult task.
Individuals with Down syndrome can have ADHD but they should be evaluated for attention span and impulsivity based on developmental age and not strictly chronological age. The use of parent and teacher rating scales such as the Vanderbilt and the Connors Parent and Teacher Rating Scales can be helpful in diagnosis. Anxiety disorders, language processing problems and hearing loss can also present as problems with attention.
These can sometimes be very simple; for example, a child may always want the same chair. However, obessive/compulsive behavior can also be more subtly repetative, manifesting through habits like dangling beads or belts when not engaged directly in an activity. This type of behavior is seen more commonly in younger children with Down syndrome. While the number of compulsive behaviors in children with Down syndrome is no different than those in typical children at the same mental age, the frequency and intensity of the behavior is often greater. Increased levels of restlessness and worry may lead the child or adult to behave in a very rigid manner.
Autism Spectrum Disorder
Autism is seen in approximately 5-7% of individuals with Down syndrome. The diagnosis is usually made at a later age (6-8 years of age) than in the general population. Regression of language skills, if present, also occurs later (3-4 years of age). Potential intervention strategies are the same as for any child with autism. It is important for signs of autism to be identified as early as possible so the child can receive the most appropriate therapeutic and educational services.
How Should Parents and Caregivers Approach Behavior Issues in Individuals With Down Syndrome?
- Rule out a medical problem that could be related to the behavior.
- Consider emotional stresses at home, school or work that may impact behavior.
- Work with a professional (psychologist, behavioral pediatrician, counselor) to develop a behavior treatment plan using the ABC's of behavior. (Antecedent, Behavior, Consequence of the behavior).
- Medication may be indicated in particular cases such as ADHD and autism.
Intervention strategies for treatment of behavior problems are variable and dependent on the individual's age, severity of the problem and the setting in which the behavior is most commonly seen. Local parent and caregiver support programs can often help by providing suggestions, support and information about community treatment programs. Psychosocial services in the primary care physician's office can be used for consultative care regarding behavior issues. Chronic problems warrant referral to a behavioral specialist experienced in working with children and adults with special needs.
What About Behavioral Changes in Adulthood?
These can be caused by a number of factors: difficulty with transitions into adolescence or young adulthood, with the loss of social networks, departure of older siblings, death of loved ones, move out of the home or transfer from a protective school environment into a work situation; sensory deprivation, either visual (e.g. cataracts) or auditory (hearing loss); emotional trauma; hypothyroidism; obstructive sleep apnea; depression; and Alzheimer’s disease. While Alzheimer’s disease occurs earlier and more often in adults with Down syndrome than in the general population, not every behavioral or cognitive change in an adult with Down syndrome should be ascribed to this form of dementia. The reversible causes enumerated above should be considered, sought after and treated.
