Sorry folks, the PRIDE-HD trial did NOT show that Pridopidine slows the progression of Huntington's disease

Sorry folks, the PRIDE-HD trial did NOT show that Pridopidine slows the progression of Huntington's disease

Dr Jeff Carroll on September 30, 2016

A recent press release from Teva Pharmaceuticals has the HD community excited, claiming "Pridopidine Demonstrates Slowing of Progression of Huntington Disease in PRIDE-HD Study". What's pridopidine, and what can we really say about HD progression in patients treated with it?

Ultra-rare mutations highlight the importance of the HD gene in brain development

Ultra-rare mutations highlight the importance of the HD gene in brain development

Megan Krench on August 29, 2016

A relatively new technology called exome sequencing has identified a few families with novel mutations in their HD genes. These are different than the mutation that causes HD, but allow researchers to better understand the normal role of the HD gene.

Deutetrabenazine for Huntington's disease: a positive trial but the FDA says no? Not exactly...

Deutetrabenazine for Huntington's disease: a positive trial but the FDA says no? Not exactly...

Dr Peter McColgan on August 17, 2016

A scientific paper declares positive results for a trial of deutetrabenazine in Huntington's disease, but the headlines report the FDA has rejected the drug. Confusing stuff! The reality is positive overall for this new way of treating uncontrollable movements in HD, but patience will be needed to see where it all ends up.

Slightly long CAG repeats are more common than we thought

Slightly long CAG repeats are more common than we thought

Dr Jeff Carroll on July 05, 2016

Everyone with Huntington's disease has inherited the same type of mutation from their mother or father, an extra-long repetitive stretch of the sequence C-A-G in their HD gene. But the length of the mutation varies between individuals, and longer repeats are associated with earlier onset of symptoms. A huge new international study reveals that slightly longer-than-normal CAG stretches are much more common than we thought. Surprisingly, this turns out to be good news.

Through a Broader Lens: Looking at Non-Motor Symptoms in HD

Through a Broader Lens: Looking at Non-Motor Symptoms in HD

Melissa Christianson on January 25, 2016

Common depictions of HD emphasizing only its movement symptoms paint an incomplete picture of the real disease. HD causes both motor and non-motor symptoms that, together, affect the entire body. Now, scientists are using a broader lens to explore this full set of HD symptoms and determine how symptoms might be related in the disease.

Looking Past the Spin: Results from a Clinical Trial of Cysteamine

Looking Past the Spin: Results from a Clinical Trial of Cysteamine

Melissa Christianson on December 18, 2015

In early December, Raptor Pharmaceuticals released clinical trial results evaluating a drug called cysteamine in Huntington’s disease. News headlines about this trial are heavy on media spin, and so HDBuzz is here to break down what these new results really mean for the Huntington's community.

Through the eyes of a friend: changes in mood and behavior in early HD

Through the eyes of a friend: changes in mood and behavior in early HD

Leora Fox on December 02, 2015

The family and friends of individuals with HD often tell doctors that they began to notice changes in behavior long before a diagnosis was made. To better understand these early signs, researchers analyzed a psychological questionnaire filled out yearly for a decade by thousands of HD mutation carriers and their companions. The companions were more likely to perceive worsening symptoms over time.

Liftoff: First humans treated with gene silencing drugs for HD!

Liftoff: First humans treated with gene silencing drugs for HD!

Dr Jeff Carroll on October 22, 2015

Today brings news that the first Huntington's Disease patients have been successfully dosed with gene silencing drugs targeting the HD gene. These brave volunteers are the first HD patients to ever be treated with drugs designed to attack HD at its root cause, a treatment approach with huge potential. What about this news has us so excited?

Switching it up: variety in the HD gene affects symptom onset

Switching it up: variety in the HD gene affects symptom onset

Melissa Christianson on May 29, 2015

Just like it is difficult to predict exactly when a storm will hit, predicting when Huntington’s disease symptoms will arise for any particular person is hard to do. However, new research suggests that tiny changes in the on switch of the Huntington’s gene affect symptom onset – and may provide important information in the search for Huntington’s therapies.
