Neurodegenerative diseases such as Alzheimer’s, Parkinson’s, and Huntington’s have long been likened to raging fires, with toxic protein clumps engulfing the brain. But behold, a group of brilliant scientists has now identified the ignition point of at least one of these devastating diseases and even uncovered a way to extinguish the flames!


The groundbreaking study focuses on Huntington’s disease, a rare inherited brain disorder that tragically curtailed the life of renowned songwriter Woody Guthrie. However, the implications of this research extend far beyond Huntington’s, encompassing other degenerative brain conditions, notably Alzheimer’s.

Corinne Lasmézas, an esteemed neurodegenerative disease researcher at the Wertheim UF Scripps Institute in Jupiter, Florida, excitedly declares that this finding “opens the path” to identifying the initial event responsible for ailments like Alzheimer’s and Parkinson’s. The magnitude of this breakthrough cannot be overstated.


In the case of Huntington’s, afflicted individuals progressively lose control over their motor functions, experience cognitive impairment, and ultimately succumb to the disease, explains Randal Halfmann, a researcher at the Stowers Institute for Medical Research in Kansas City, Mo., and one of the study’s authors.


Similar to other neurodegenerative disorders, Huntington’s occurs when proteins in the brain fold abnormally and clump together. These clusters of aberrant proteins then trigger nearby proteins to misfold and form their own clumps.

Halfmann compares the progression of the disease to witnessing a forest fire, desperately seeking to discern its initial spark. Understanding the molecular matchstick responsible for this destructive blaze became the primary goal for his team.

To achieve this, the researchers devised a method to capture a fleeting and typically invisible event called nucleation. They created multiple versions of a protein segment called PolyQ, which becomes toxic in Huntington’s, through genetic manipulation. By introducing various iterations of PolyQ into cells and observing signs of misfolding and clumping, they embarked on an enlightening journey.

Halfmann likens their approach to navigating a dark room, where constant bumping into objects ultimately reveals the room’s shape. Through perseverance and trial and error, the team succeeded. They discovered that the initial fire in the brain is ignited by a single molecule of PolyQ.

With this pivotal breakthrough, the researchers were then able to prevent the spread of the harmful molecule—at least within their laboratory setting. They achieved this by flooding the cell with proteins that effectively smothered the flame before it could cause any damage.

The next step on this exhilarating scientific journey involves developing a drug that can replicate this effect in humans, affirms Halfmann. Ultimately, the success of this research lies in creating a therapy that will benefit those affected by neurodegenerative diseases. The potential impact is not limited to Huntington’s alone; it has the power to revolutionize treatments for other brain disorders by interrupting the cascade of events that lead to debilitating brain damage.

Lasmézas underscores the importance of addressing the root cause of these diseases, stating that prevention should start at the moment the fire ignites rather than allowing it to consume the entire forest. The field of Alzheimer’s research, for instance, has begun recognizing this crucial lesson. Earlier drug attempts targeted the large amyloid plaques found in the brains of individuals with Alzheimer’s but yielded unsatisfactory results. These drugs focused on the remnants of a forest that had already burned.

However, Lasmézas points out that recent drugs like lecanemab demonstrate a more precise approach. They not only eliminate large amyloid clumps but also target the smaller, more toxic clumps that form before the appearance of plaques. This targeted approach reflects a

deeper understanding of the initial triggers of Alzheimer’s.


Studies like the one delving into Huntington’s disease signify a remarkable advancement in the quest to slow down or halt neurodegenerative diseases, including Alzheimer’s and Parkinson’s, Lasmézas asserts. Over the past 15 years, a veritable explosion of knowledge has propelled scientists forward, unveiling the mechanisms that underpin these enigmatic conditions.


The discovery of the spark behind neurodegenerative diseases is an incredible stride toward unlocking effective treatments and prevention strategies. With each breakthrough, we edge closer to a future where these devastating fires are tamed, allowing hope and healing to prevail.
