Depression Can Affect Your Ability to Focus, Make Your Brain Go Fuzzy
Mood swings, poor appetite and constant tiredness are few symptoms that anyone suffering from depression could experience. But another symptom which surfaces and seems to get worse over time is a person's inability to focus or think. According to a study done at the University of Michigan, 'people with depression often feel that their thinking ability has gotten fuzzy, or less sharp than before their symptoms began. This also applies to people with bipolar disorder.'

The study appeared in the journal BRAIN and proved that the condition 'fuzzy thinking' falls under the category of mood disorders and isn't completely unrelated. This could change the way doctors think about, diagnose and treat their patients.

For the study, researchers from the University of Michigan's medical school and depression centre analysed 612 women, over two-thirds of whom had experienced either major depression or bipolar disorder. Seen as groups, women with depression or bipolar disorder did equally badly on the test, which required sustained concentration.

The test asked them to react rapidly when certain letters flashed briefly on a screen amid a random sequence of other letters. Compared with the group with no mental health conditions, the groups with either diagnosis lagged noticeably on this standard test of cognitive control.

On the brain scans, the researchers found that the women with depression or bipolar disorder had different levels of activity than healthy women in a particular area of the brain called the right posterior parietal cortex. The level of brain activity in those suffering from depression was higher than the level of brain activity in healthy individuals. For those with bipolar disorder, the brain activity was even lower. The area where the differences were seen helps control "executive function" - activities such as 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. So if you feel like you can't concentrate or focus on a particular task, are distracted and unable to follow orders, then maybe it's a by-product of depression or bipolar disorder.
