Cognitive dysfunction occurs when humans face a problem in understanding data and analyzing it. It occurs as a disorder in the brain that stops or limits the ability of the brain to work efficiently. The main cause for such disorders is mainly through head injuries which might affect areas in the brain.
However, in some cases, where head injuries are not present, it gets really challenging for doctors to understand the reason behind cognitive dysfunction. Tackling this issue, a study conducted on non-brain-related injuries was aspiring to understand why cognitive dysfunction are related. The study was conducted by a team of researchers from by Western University and Lawson Health Research Institute have shown that cognitive dysfunctions might not be detected from the injury however it can still be faced as a side effect for injured patients who were admitted to the ICU.
The study included the use of 20 patients who had non-brain-injuries and were admitted to the ICU. They were assessed after leaving the ICU and showed signs of cognitive areas in the brain including the memory, decision-making, attention and reasoning
The study was published by Adrian Owen (a Western neuroscientist and a professor at Schulich Medicine & Dentistry) in the PLOS ONE journal. According to Dr. Owen, many different patients are admitted in the ICU for reasons that differ from brain injuries. He explains through his study saying, “ Many people spend time in an intensive care unit following a brain injury and, of course, they often experience deficits in memory, attention, decision-making and other cognitive functions as a result.”
