One day we may be able to consistently choose medications that offer optimal benefit and minimal adverse events—without subjecting our patients to unsuccessful trials. Thanks to quantitative EEG (OEEG) testing and pharmacogenetic testing, that day may be coming closer.
How quantitative eeg works
QEEG adds modern computer and statistical analyses to traditional EEG recordings. The computer creates a graphic display on a schematic map of the head. The procedure is often called brain electrical activity mapping (BEAM) or simply “mapping.” New tool: Genotyping makes prescribing safer, more effective, Current Psychiatry, September 2004.) Physicians can order any combination of gene tests, which cost about $150 to $200 each, or all available tests for a discounted price of approximately $600.
Genelex and Signature Genetics can create individualized CYP-450 function reports to facilitate prescribing and customized reports that take into account the patient’s medication and diet regimen. Genelex also offers an Internet-based software tool, GeneMedRx, which allows doctors to customize medication regimens based on both potential drug-drug interactions and genomic information.
Signature Genetics offers a prospective assessment of drugs based on genetic test results. This assessment provides a comprehensive report of which medications are affected by the test results.
Genetic profiling can help psychiatrists improve the likelihood of treatment success and minimize potential drug-drug interactions and adverse reactions. Patients will be more satisfied, knowing that their medications fit their individual needs. Also, as more is learned about genetic analysis, genetic testing could one day reveal susceptibility to Alzheimer’s disease, heart attack risk, or other medical problems.
As with quantitative EEG, however, few insurance companies cover genetic testing. Also, patients found to have a higher likelihood of developing certain diseases could potentially be charged higher health insurance premiums.
