Lewy body disease, a lesser-known condition, can lead to devastating disorders like Lewy body dementia and Parkinson’s disease.
It’s characterized by the accumulation of abnormal protein clusters called Lewy bodies in the brain. Until now, diagnosing Lewy body disease was only possible post-mortem.
However, researchers at Lund University in Sweden have made a landmark discovery that could change this.
Understanding Lewy Body Disease
Lewy body disease might not be a household name, but its impact is significant. It causes Lewy body dementia and Parkinson’s disease, affecting both movement and cognitive functions.
The disease is characterized by the buildup of abnormal protein clusters known as Lewy bodies in the brain.
A Game-Changing Discovery
Previously, the only way to definitively diagnose Lewy body disease was by examining the brain after death. However, the Swedish research team has developed a new method.
They use a test on the fluid surrounding the brain and spinal cord to detect these problematic proteins. When applied to over 1,100 individuals with no cognitive or motor issues, the test revealed signs of Lewy bodies in almost 10% of cases.
This groundbreaking finding means early diagnosis, even before symptoms appear, is now possible.
A Surprising Connection to the Sense of Smell
Researchers also uncovered a strong link between Lewy body disease and a loss of the sense of smell. Individuals testing positive for Lewy bodies were already experiencing smell-related issues before other symptoms emerged.
This suggests that people over 60 might benefit from a smell test. If they perform poorly, a more detailed examination involving spinal fluid could confirm Lewy body disease.
The Importance of Early Diagnosis
Timely diagnosis is crucial for brain-related diseases. Scientists are working on medications to slow down or halt the progress of Lewy body disease.
Early diagnosis could enable healthcare providers to administer these treatments before severe damage occurs.
Additionally, some individuals with Lewy body disease also had protein build-ups associated with Alzheimer’s, allowing medical professionals to predict disease progression more accurately.
What Lies Ahead
While researchers are optimistic, they acknowledge that creating a blood test for Lewy body disease might be challenging due to lower protein concentrations in the blood.
Nevertheless, this discovery opens new avenues for early diagnosis and treatment, offering hope to millions affected by this condition and their families.
In conclusion, Lund University’s groundbreaking discovery allows for the early detection of Lewy body disease, previously only diagnosable post-mortem.
This development holds great promise for improving the lives of those impacted by this condition and advancing our understanding of neurodegenerative diseases.
The research has been published in the prestigious science journal, Nature Medicine.
