Detecting suicidal thoughts in antidepressant-takers

Posted Apr 10 2010 8:48pm

Reporting in the April edition of the peer-reviewed journal Acta Psychiatrica Scandinavica, Aimee Hunter, an assistant research psychologist in the UCLA Department of Psychiatry, and colleagues report that by using quantitative electroencephalographic (QEEG), a non-invasive measurement of electrical activity in the brain, they were able to observe a sharp reduction of activity in a specific brain region in individuals who proved susceptible to thoughts of suicide — within 48 hours of the start of treatment. The researchers treated 72 people suffering from major depressive disorder (MDD) with one of two SSRIs, fluoxetine or venlafaxine, or with a placebo. All were evaluated by a clinician using the Hamilton Depression Rating Scale, a standard instrument that assesses the severity of a wide range of depression symptoms. Of the 37 participants on medication, five (13.5 percent) had worsening thoughts of suicide. (ScienceDaily)
