Problematic behaviorsthat are not features of a bona fide psychiatric disorder are often best understood through functional behavioral analysis, which examines antecedents and consequences of problematic behaviors and identifies their predictable outcomes, such as gaining attention, avoiding a task, or securing a desired item. Rather than being given a prescription for psychoactive medication, many adult patients with IDD and problematic behaviors might be best served by having you order consultation with a certified behavior analyst. The analyst will conduct an evaluation and, along with family or residential staff and the patient, craft a behavioral support plan to address core drivers of the undesired behavior. Behavioral support plans might be enriched by multidisciplinary input from a speech and language pathologist, habilitation professionals, occupational and physical therapists, a neuropsychologist, and others.23
Antipsychotic medications are often initiated without a careful diagnosis. In addition, they often lead to insulin resistance, metabolic syndrome, and massive weight gain.
Resources to help you address the physical, mental, and behavioral health problems of these patients are available online through Vanderbilt Kennedy Center’s “Toolkit for primary care providers” (https://iddtoolkit.vkcsites.org).
CASE
During your examination, you review Ms. S’s vital signs, including body mass index (BMI). You calculate that she is morbidly obese—BMI, 37—in the setting of a known comorbidity, diabetes.
Ms. S tells you that she is interested in having a healthy lifestyle, but feels frustrated because she does not know how to make the necessary changes. You discuss with her how some medications, including risperidone, can promote weight gain, and that it is important for her mental health provider to carefully reassess whether she needs to continue the drug.
Weight management in a patient population that tends to be sedentary
Patients with IDD are more likely to live a sedentary lifestyle. Compared to adults who do not have IDD, adults with IDD—especially women and patients with Down syndrome—are reported to have a higher prevalence of obesity.24
