Study: The Smell Of Ear Manufacturers Can Reveal The Beginning Of Parkinson's Disease

JAKARTA - Recent research shows the smell of human ear impurities could be an early indicator of Parkinson's disease, a serious neurological disorder that can cause progressive brain damage. These findings provide new hope in Parkinson's early detection, which has often been recognized for its faint initial symptoms.

Reporting from the New York Post page on Friday, June 27, according to a study published in the journal Analystical Chemistry, volatile chemical compounds (volatile organic compounds/VOCs) contained in the sebum, namely oily substances found in ear impurities, show striking differences between healthy people and people with Parkinson's disease. This difference was detected through a distinctive odor emitted by the compound.

Parkinson's disease is a condition that affects the central nervous system, causes symptoms such as shaking, muscle stiffness, and slow motion. Along with the development of the disease, brain damage will further spread, impacting motor and cognitive functions.

The most interesting thing is that scientists found that the smell of ear impurities can reflect internal processes such as chronic inflammation, oxidative stress and neurodegeneracy, which are early signs of Parkinson's.

Four compounds identified as potential biomarkers are:

- Ethylbenzene

- 4-ethyltoluene

- Pentanal

- 2-pentadecyl-1.3-dioxolane

Researchers in China use data from ear impurities to train a system based on smell artificial intelligence (AIO). This technology is able to simulate the sense of human smell and identify differences in smell with an accuracy of 94%.

If it continues to be developed, this technology has the potential to be used as a low-cost, fast, and non-invasive initial screening tool, much more practical than tests such as MRI or spinal liquid retrieval.

Parkinson's early detection is very important because today's treatment can only slow symptoms, not cure disease. The sooner Parkinson's is detected, the greater the chance of maintaining patient's quality of life and delaying further brain damage.

"Ideally, this method can replace more invasive approaches such as biopsy or brain scans," said Dr. Joohi Jimenez-Shahed, a neurologist from Icahn School of Medicine at Mount Sinai, who was not involved in the study.

Although the results are promising, this study is still limited to one clinic in China with a limited number of participants. The researchers stated that further studies in various locations and various ethnicities were needed to ensure the validity and accuracy of this method globally.

"It needs wider testing before this technology can be used clinically." said Hao Dong, the study's lead researcher.

The discovery that the smell of ear droppings can reveal the risk of brain damage due to Parkinson opens new avenues in the field of neurological diagnosis. If further developed, this technology could be a major breakthrough in early detection of serious brain disease, as well as providing hope for millions of people around the world.
