Researchers at Indiana University School of Medicine have reported that a combination of the stimulant drug methylphenidate with a process known as cognitive-behavioral rehabilitation is a promising option to help people who suffer from persistent cognitive problems following traumatic brain injury.
The study is believed to be the first to systematically compare the combination therapy to alternative treatments. It was published recently online in the journal Neuropsychopharmacology , a Nature publication.
“The researchers, led by Brenna McDonald, PsyD, associate professor of radiology and imaging sciences, and Thomas McAllister, MD, chairman of the Department of Psychiatry, compared the effectiveness of two forms of cognitive therapy with and without the use of methylphenidate, a drug used to treat attention-deficit/hyperactivity disorder and better known by its trade name, Ritalin,” a press release by Indiana University reads. “In the Memory and Attention Adaptation Training intervention – also used to assist patients with cognitive issues following breast cancer chemotherapy – therapists work with patients to help them develop behaviors and strategies to improve performance in memory and other cognitive tasks. In this study, this ‘metacognitive’ approach was compared with Attention Builders Training, which Dr. McDonald likened to more of a ‘drill and practice’ approach.”
Seventy-one people participated in the six-week study. The adult participants had at one time or another experienced either a traumatic brain injury or a blow to the head with some alteration of consciousness. All participants had experienced the TBI at least four months prior to the study and all had complained of having cognitive issues or had identified with cognitive problems in testing.
“The participants were divided into four groups: the two cognitive therapy approaches with the drug therapy, and the two approaches with placebo. After six weeks, the researchers found that participants in the combination metacognitive-Ritalin group improved significantly better in word list learning, nonverbal learning and measures of attention-related and executive function,” the press release reads. “However, Dr. McDonald cautioned that due to the relatively small number of participants in the each of the four arms of the trial – 17 to 19 people each – the results of the trial should be considered preliminary.”
Nonetheless, the work breaks new ground in providing evidence for the combination therapy.
