The result of depression can in fact affect a person’s state of mind, a new study revealed, which is classified as a mood disorder.
The University of Michigan’s medical school and Depression Centre researchers had evaluated 612 women to study further.
It showed that more than two-thirds of the women evaluated had episodes of depression and may even have bipolar disorder.
The women were then grouped according to severeness and came out that those suffering depression and bipolar disorder did the same in the examination which were as bad . The need for a longer period of concentration is suggested.
During the evaluation, they were expected to respond quickly as particular letters briefly display on a screen among other letters in no definite order.
The study found that the group with depression or bipolar disorder had clearly showed they were falling behind than those without any mental health problem on the standard evaluation of cognitive control.
The researchers conducted brain scans that revealed women with depression or bipolar disorder had distinct degree of activity than those women who were healthy in a certain part of the brain which is known as the right posterior parietal cortex.
The activity in this area in those who had depression was higher than in those who were healthy when it showed lower in those with bipolar disorder.
The differences that resulted in the evaluation in the area helps control “executive function” which includes working memory, problem solving and reasoning.
“The results could transform the way doctors and patients think about, diagnose and treat depression,” said Kelly Ryan, neuropsychologist and lead author of the study.
