Quantitative EEG (QEEG) Method to Identify Individuals at Risk for Adverse Antidepressant Effects

Detailed Technology Description

The invention utilizes output from quantitative electroencephalographic (QEEG) recordings for an individual that are obtained at two time-points: baseline (T1; prior to the start of drug) and (T2; early in the course of antidepressant treatment). From these recordings, a single measure is generated that can be used to determine the chance or percent likelihood that the individual will experience medication-related increases in anxiety, agitation, hostility, and/or suicidal ideation during continuation of the specific antidepressant over the subsequent two months.

Title: Quantitative EEG method to identify individuals at risk for adverse antidepressant effects
Usefulness: Quantitative EEG method to identify individuals at risk for adverse antidepressant effects
Summary: A method of identifying subjects at risk for adverse effects from a psychotropic or central nervous system (CNS) active treatment such as antidepressant treatment, e.g., within two days of initiating antidepressant treatment determine one's risk of experiencing increased anxiety, agitation, hostility, and/or suicidal ideation with continuation of that medication. It determines one's risk of experiencing overall clinical worsening of depressive symptoms with continuation of that medication. It determines the safety of putative antidepressant and other psychotropic compounds at various doses.
Novelty: Risk identification method for a psychotropic treatment involves determining change in cordance before and after two days of treatment by calculating a difference between the two resultant values calculated using two sets of physical values

State Of Development

In data from depressed patients randomized to antidepressant treatment, our QEEG biomarker predicted worsening suicidal ideation with 97% accuracy (80% sensitivity, 100% specificity) and .86 Area under the Receiver Operating Curve. (These results need to be prospectively replicated in independent samples.) The biomarker did not predict suicidal worsening among depressed subjects treated with placebo.

*Abstract

This invention is a method that uses human EEG output to determine, early in the course of antidepressant treatment, whether an individual has an elevated risk of developing adverse medication effects. In the clinical setting, this method will provide a neurophysiologic marker, early during antidepressant treatment, that will help determine one’s risk of experiencing anxiety, agitation, hostility, and/or increases in suicidal ideation with continuation of that medication.
