At the University of Michigan completed a multi-year experiment to identify signs of dementia in the earliest stages. The state of the body, when the usual alarming symptoms do not exist, and the disease is already progressing, can be calculated from the selective loss of smell. For example, if a person suddenly stopped feeling the smell of gasoline or soap.
The study lasted 10 years, much longer than similar programs, which allowed us to find subtle patterns that develop very slowly. In the mixed racial group, there were 2,462 middle-to-old-age people. All of them were regularly forced to take tests to reveal Parkinson’s by medical methods, as well as to pass tests for smell.
It was not exotic flavors that sniffed the experimental, but 12 common smells, from cinnamon and lemon to gasoline and soap. And give your assessment of the intensity of the fragrance, from weak to strong. Later, at the end of the experiment, 42 patients officially confirmed Parkinson’s disease according to proven markers-all of them had a very weak scent throughout the experiment. More precisely, the analysis of statistics gave such a result: in people with a weak sense of smell at the beginning of the research, the chance to get dementia was 5 times higher than that of their colleagues with a normal sense of smell.
Scientists insist that they have corrected the data and took into account such factors as smokers, smoking, head trauma and personal psychiatric abnormalities. It should be noted that this study is of a fundamental nature, and no specific tests have yet been made to determine the signs of Parkinson’s disease according to the state of the person’s sense of smell .
