Scientists give emotional celebration as Huntington’s disease successfully treated for first time

by

As a long-time follower of Huntington’s research, I’m absolutely thrilled to hear about this incredible breakthrough! Scientists have finally discovered a gene therapy that can actually slow down how Huntington’s disease gets worse – it’s the first time anything like this has been possible, and it gives so much hope for the future.

Huntington’s disease is a serious, inherited brain disorder that gets worse over time. It damages nerve cells, leading to difficulties with movement, thinking, and behavior.

Huntington’s disease was first identified in 1872 by Dr. George Huntington, and unfortunately, there’s still no cure. Current treatments can only help manage the symptoms, which typically begin to appear when people are in their 30s or 40s.

After over a hundred years, researchers have finally found a method to effectively slow down this condition, which has amazed and encouraged doctors.

Researchers slow Huntington’s disease by 75% with gene therapy

Medical researchers announced on September 24, 2025, that a three-year study showed a particular gene therapy can help slow down Huntington’s disease.

So, basically, this disease happens because of a messed-up protein – the huntingtin protein – in my brain. It changes into something toxic and slowly starts destroying my brain cells. It’s like a slow, internal attack, and that’s what causes all the problems.

Scientists used gene therapy – a technique involving a modified, harmless virus – to deliver a specific set of genetic instructions directly into several deep areas of the brain. They altered the virus to carry the desired DNA and then introduced it into the patients.

Once inside the cell, the new DNA begins to work, binding with RNA and interfering with the way the huntingtin gene normally makes proteins.

This complex surgery can last from 12 to 18 hours. Doctors carefully inject the treatment using a thin tube and MRI scans, making it a demanding process for both the medical team and the patient, and likely a very costly one.

uniQure, a gene therapy company, announced results on September 24th indicating that patients showed, on average, a 75% reduction in the progression of Huntington’s disease three years after receiving treatment.

Professor Tabrizi, director of the University College London Huntington’s Disease Centre, described the trial results as “remarkable” in an interview with the BBC.

She said they never imagined the disease would progress 75% more slowly, even in their most optimistic expectations.

I was so moved when I heard the news, I actually got a little teary-eyed! Professor Ed Wild, a neurologist at the National Hospital for Neurology and Neurosurgery at UCLH, admitted he had the same reaction – it really hit him hard, too.

He explained that they weren’t sure they’d ever achieve such a significant outcome, so now that it’s happened – and the impact is even greater than they imagined – it’s hard to put into words how amazing it feels.
