Feeling depressed makes our brain less reactant. New study shows that depression has a serious impact on the way we are able to visualise and perceive information.
Depression is a disease that has many effects on the human mind and it can be encountered in many forms and manifestations.
People feeling depressed and with a low energy might have the feeling that their thinking ability is not that sharp anymore or that it has turned quite foggy.
A recent study has proved that the effect is scientifically proven and it actually exists, which categorizes this condition as a mood disorder.
For their experiment, scientists from the medical school of Michigan University have observed a number of 612 women. Up to 60% of them of them have been dealing with severe depression or bipolar disorder in the past and were given brain scans.
Participants in the study were asked to have a fast reaction when specific letters flashed quickly before their eyes while being mixed with other letters. The results showed that both depression or bipolar disorder women, presented the same delayed reaction of noticing, compared with the women with no mental disorders.
Even if the majority of the women suffering from depression or bipolar disorder showed similar results with the healthy participants, almost all those who made it in the bottom 5% was suffering from one of the mental disorders.
The brain scans results showed that the women dealing with depression or bipolar disorder presented different levels of activity in a certain region of the brain known as the right posterior parietal cortex.
Women suffering from depression, presented higher activity in that brain area, compared to healthy women, while the ones suffering from bipolar disorder presented lower activity.
This particular brain area, where the differences were spotted, aids in controlling executive functions, such as memory, finding solutions for problems and reasoning.
The results of the research might be helpful for doctors in finding different perspectives of diagnosing and treating depression, explained the lead author of the study, neuropsychologist Kelly Ryan.
People dealing with the so called “fuzzy thinking” are advised reduce the stress factors from their daily routine, take more care of their emotional state and be more careful about the environment they exposing themselves to.
Trying to remain positive and induce a calm state is an amazing therapy for the brain. The first changes have to be made in the daily lifestyle and people should reflect on what possibly could be provoking the mental fogginess, explained experts.
