Testing for Depression
In the past, depression could only be diagnosed based on a patient’s reported symptoms. However, researchers at the University of Illinois may have found a medical test that can accurately diagnose depression.
A protein called Gs Alpha is normally found in a specific area in the brain. When this protein has moved, it is a biomarker indicative of depression. The test also helps doctors determine whether an antidepressant is working within four to five days instead of the month or so that it normally takes.
Though this research is in the early stages and will not be available to the public for years, it's an encouraging step for doctors to better diagnose depression patients sooner. Check back here for regular updates on depression research. [Science Daily]
