A novel study presented that the effect is indisputably tangible, calculating that this condition falls into the category of disposition illnesses.
University of Michigan school of medicine and depression center researchers conducted a study about depression by analyzing 612 women.
More than 2/3 of the subjects experienced either bipolar disorder or mental depression.
The depressed women or those with bipolar disorder both performed poorly on the test, which required continuous unrelenting concentration.
The test conducted required them to react promptly when certain letters were flashed fleetingly on a screen during a random sequence of other letters.
Associating the individual which has no mental health conditions, the groups with either of the two diagnosis lagged conspicuously on this standard test of cognitive control.
The researchers found out on their brain scans, that women who were mentally depressed or had bipolar disorder registered different levels of activity as compared to healthy women in a certain location in the brain called the right posterior parietal cortex.
For persons with mental depression, this area had higher activity levels than in healthy individuals, while those with bipolar disorder it was identified as lower.
The specific area within the brain where the differences were “seen” supports in the control of “executive function”, activities like reasoning, problem solving and working memory.
“The results can transform the way doctors and patients think about, diagnose and treat depression,” said Kelly Ryan, a neuropsychologist and the lead author of the study.
