(National Monitor) – It can be difficult to focus when you are suffering from depression or anxiety. A new study reveals that you are not imagining things – brain function does in fact diminish in certain areas leading to what is commonly referred to as ‘fuzzy thinking’.

The University of Michigan School and Depression Center recently published their findings in Oxford’s Journal of Neurology. Researches found that the part of the brain responsible for reasoning and working memory (collectively called ‘executive functions’) has different levels of activity in normal people and in people suffering from bipolar disorder or depression.

The scientists recruited 612 female participants to take a simple test. Nearly two-thirds of them had suffered or were suffering from some sort of mental affliction, such as depression, bipolar disorder, or anxiety.
