PET May Detect Dementia: Revealed Through Decade Long Research

The decade long researches conducted by the scientists had revealed the secret of detecting dementia, a usual and dangerous Alzheimer’s disease of old age, through Positron Emission Tomography (PET), which had been published in a journal on Nuclear Medicine in its January edition. Their researches were based on various studies made to assess technique of molecular image which relates an injected biomarker, called 18F-FDG, with PET, which provides images of the functions of biological procedures, to detect the main resource of reduction of the metabolic structure of mind that may cause dementia. This imaging of neurodegenerative disease through PET makes the disease evident to the physicians which may help in diagnosing the disease more accurately than in earlier days.

“The new data support the role of 18F-FDG PET as an effective addition to other diagnostic methods used to assess patients with symptoms of dementia,” says Nicolaas Bohnen, MD, PhD, lead author of the study and professor of radiology and neurology at the University of Michigan, Ann Arbor, Mich. “The review also identified new literature showing the benefit of this imaging technique for not only helping to diagnose dementia but also for improving physician confidence when diagnosing a patient with dementia. This process can be difficult for physicians, especially when evaluating younger patients or those who have subtle signs of disease.”

Dementia can not be defined as a particular disease but it is a collection of signs that may cause a reduction in the ability to recognize things which is caused due to some injury or the retrospective affect of certain disease which may influence the part of brain that controls the recognizing instinct of the person like language, memory, mobility and language. Dementia can be seen in various forms which may cause due to effect of disorder on various parts of brain, showing its different effects. The forms of dementia can be differentiated accurately by the physicians by the use of PET-FDG and diagnose it for proper treatment. The significance of evaluating dementia through molecular imaging system has been felt enough as it is now used as the documentary proof of the state of brain of the patient of dementia.

Thus, it can be concluded in the words of Bohnen, who told that the use of molecular imaging technique through18F-FDG PET improves the correctness of diagnosing dementia helps the physician to reach to an accurate and better treatment of the patient.
