Clinical guidance
The investigators operationalized DESR using the eight-item Emotional Dysregulation (ED) subscale of the Barkley Current Behavior Scale. They then used receiver operating characteristic curves to identify the optimal cutoff on the Barkley ED Scale that would categorize patients as having high- vs. low-level DESR.
“We wanted to give some guidance to clinicians, using a very simple rating scale that was developed by Dr. Barkley. It is one we think configures this syndrome of emotional dysregulation and emotional impulsivity,” Dr. Biederman said.
The study included 441 newly referred 18- to 55-year-old men and women who met DSM-5 diagnostic criteria for ADHD.
Using a cutoff score of 8 to represent high levels of DESR, the researchers identified 191 adults as having high-level DESR and the rest as having low-level DESR.
Those with high-level DESR had significantly more severe symptoms of ADHD, executive dysfunction, autistic traits, levels of psychopathology, and worse quality of life, compared with those with low-level DESR.
The problem of emotional dysregulation in ADHD is widespread and affects many people, Dr. Biederman noted.
“If you take 5% of adults at a minimum and 10% of children with ADHD [and] if 50% of those have emotional dysregulation, we’re talking about millions of people. And it is very morbid,” he said. “Having emotional dysregulation problems will get you in hot water.”
Promising results
Commenting on the findings for this news organization, Ira D. Glick, MD, professor emeritus of psychiatry and behavioral sciences, Stanford (Calif.) University, said the new studies are important.
He noted that, although ADHD has become more accepted as a “disease of the brain” over the past 20 years, patients with the disorder and their families often are not accepting of the diagnosis.
“Instead, they try to downplay it. They say this is just a ploy by psychiatrists to get business or this is just normal boys’ behavior, [and] they don’t need medicines,” said Dr. Glick, who was not involved in the current research.
“Biederman is trying to make clear that ADHD is a brain disease, and DESR symptoms are cardinal signs of a brain illness,” he said.
Dr. Glick also agreed that text messaging could be very useful for these patients.
“Text messaging might be helpful, especially in this population which can often be disorganized or forgetful. The results of that study were very promising,” he said.
Dr. Biederman is in the process of commercializing the text program used in the study. Dr. Glick reports no relevant financial relationships.
