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?

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.

Important drug targets yielded by new genetic study of HD

Important drug targets yielded by new genetic study of HD

It’s a great mystery why different people with the same HD mutation sometimes develop symptoms at vastly different ages. Last year a huge genetic analysis gave us some interesting clues, and now, researchers are focusing in on the most promising results. A recent study shows that tiny changes within genes that repair damaged DNA can have a big effect on age of onset in HD and related diseases.

Thinking clearly about the earliest symptoms of HD and which brain regions control them

Thinking clearly about the earliest symptoms of HD and which brain regions control them

Dr Tamara Maiuri on April 18, 2016

Cognitive deficits, or difficulties thinking clearly, often appear well before the traditional clinical diagnosis of Huntington’s disease (HD). While many contend that the earliest cognitive deficits are caused by damage to the striatum – a structure deep in the brain known to be severely affected in HD – recent evidence suggests that this claim may paint an incomplete picture of the widespread changes occurring in the brains of HD patients during the very early stages of the disease.

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.

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.

Building a Better Mouse(trap): A New Model of Huntington’s Disease

Building a Better Mouse(trap): A New Model of Huntington’s Disease

Melissa Christianson on March 16, 2015

Most research on Huntington’s disease is done using animal models that mimic the human disease. However, these models typically recreate only a few of the disease’s symptoms, and there are some important symptoms that don’t show up in any model at all. Now, exciting new research is making great strides against these problems – and teaching us about the disease at the same time.

Can sad mice help treat Huntington's disease?

Can sad mice help treat Huntington's disease?

Dr Jeff Carroll on July 17, 2013

Many Huntington's disease patients suffer from depression. New mouse work from Asa Petersen's group in Lund, Sweden, suggests that part of the brain called the "hypothalamus" might play a role in this symptom of HD.
