The researchers believe that what they've found in these impairments is a biological marker of bipolar disorder that could be the makings of a test. "We're excited about this because the potential is huge," says Lagopoulos, "but we have to temper our enthusiasm" until further research can confirm these differences as statistically bullet-proof...
...doubt about whether what we're seeing in these types of studies is illness pathology or an effect of drug treatment. And is there a chance that sufferers of straight (unipolar) depression might show the same processing irregularities as bipolar patients? Which would be the death knell of a test purported to separate the two. Malhi and Lagopoulos doubt this would be the case - the two types of depression are quite different, they say-but Malhi adds: "No study has directly compared the two groups... and this would be the ideal experiment."
