It has been found out from a new study conducted by the eminent researchers of the Duke University Medical Center, in Durham, NC that lesions or scratches that are found in common owing to the application of MRI in the brains of the aged patients tend to have an indication of a potential sign of more widespread injury to the brain tissue.

According to the finding of the investigative study, hyperintense lesions have been identified as a general conclusion on neuroimaging and has been associated directly with aging, medical illness and a quantity of invasive medical procedures. To get a definite conclusion there was a definite investigative study that consisted of 82 patients between the range of 60 and the very elders. The candidates were meticulously chosen so that during the investigation they didn't get depressed and with no prior history of neurologic illness. A brain MRI with Diffusion Tensor Imaging or DTI was applied on each patient as a part of the process.   The next step that was followed by the researchers was the measurement of the volume of white matter lesions and gray matter lesions, along with the measurement of the fractional anisotropy in the white matter of frontal regions, the internal capsule, and corpus callosum. As a general rule, the increased lesion volumes were found to be connected with lower Fractional Anisotropy or FA values. This has been described as a precise evaluation of both the direction and the intensity of water diffusion and is in due course utilized as a surrogate marker in case of the integrity of the tissues.

When being asked by this correspondent about the future of the aged patients affected with these scratches in their brains DR. Warren Taylor, MD, and the most prominent person behind of the study said, "These hyperintensities are seen in most everyone as we age, although they can be more severe in some than others. We feel they're important as greater severity of these lesions is associated with a number of conditions including dementia and memory problems, depression, risk of falls, incontinence, and even higher mortality." He also went on saying, "What we found in the study is that these lesions may just be the visible sign of more widespread disease in the brain. That is, in people with more severe lesions, even brain areas that appear normal on MRI may also be affected, particularly brain areas involved in reasoning." "One theory we've used is that lesion location may distinguish why some people with a lot of these lesions seen on MRI may get depressed or develop memory problems, while others don't have these problems and do fine. The development of depression or dementia may be because a lesion occurred in areas of the brain that help control mood or memory," he concluded.
