Study Shows NeuroStar TMS Therapy(R) Improved Key Elements of Cognition in Patients with Major Depressive Disorder
Unlike Electroconvulsive Therapy (ECT), NeuroStar TMS Therapy Is Not Associated With Memory Loss
Diminished ability to think, concentrate, and make decisions is a core symptom of depression. This is often further worsened by some common depression treatments, such as some classes of medications. Most notably, electroconvulsive therapy (ECT), while extremely effective, has high rates of cognitive impairment and long-term or even permanent memory loss.
"In this study, NeuroStar TMS Therapy demonstrated no negative effect on cognition, and evidence suggests that it may even improve certain cognitive functions in depressed patients," said psychiatrist
About the Study
Cognitive function was examined in a multi-site, randomized controlled trial of NeuroStar TMS Therapy in patients with pharmacoresistant major depressive disorder (N=155 active TMS, N=146 sham TMS). Specific measures of global cognition (Mini Mental Status Examination), short-term (Buschke Selective Reminding Test) and long-term memory (Autobiographical Memory Interview-Short Form) were obtained prior to first treatment, and at four and six weeks during an acute treatment course of daily TMS. The results showed no significant difference between active TMS and placebo TMS treatment conditions on any of these measures of cognitive function, which indicates that NeuroStar TMS Therapy had no negative effect on cognition.
Additionally, each treatment group was stratified by clinical outcome (HAMD24 responder) at the end of six weeks. Within the TMS group only, there was a statistically significant improvement on the Buschke Selective Reminding Test in the TMS responders compared to TMS non-responders for both short-term recall (P = 0.0116 at four weeks; P = 0.0038 at six weeks) and delayed recall (P = 0.0463 at four weeks; P = 0.0012 at six weeks). This improvement in cognitive function was not seen in placebo-treated patients.
"We believe that the reason for the lack of negative cognitive effects with NeuroStar TMS Therapy is likely due to the focused stimulation of a key brain region, rather than the whole brain effects of both medications and ECT," said

Depression affects at least 14 million American adults each year. Researchers estimate that by the year 2020, depression will be the second leading cause of disability worldwide. Each year, over 30,000 people in the US commit suicide, 60% of which suffer from depression. The economic burden of depression in 2000 was estimated at
