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.

A multiple sclerosis drug that works for Huntington's disease: the real deal or too good to be true?

A multiple sclerosis drug that works for Huntington's disease: the real deal or too good to be true?

Melissa Christianson on November 24, 2015

Thinking problems in Huntington’s disease take a huge toll from early in the disease. Now, new work suggests that a drug already approved by the FDA to treat another brain disease – multiple sclerosis – may stave off these problems in HD mice. Could these results be real, or are they too good to be true?

Does high-dose creatine "slow the onset" of Huntington's Disease?

Does high-dose creatine "slow the onset" of Huntington's Disease?

Dr Jeff Carroll on February 11, 2014

The results of a new study called PRECREST, investigating whether the nutritional supplement creatine can slow Huntington's disease progression, have just been published. Uniquely, this studied the effects of high-dose creatine supplementation in people carrying the HD mutation, but without clear disease symptoms.

Buzzilia Video: Day 2

Dr Ed Wild on October 19, 2013

Here's Buzzilia, video 2: highlights and interviews from the World Congress on Huntington's disease 2013 in Rio de Janeiro. Jeff and Ed discuss biomarkers and talk to Dr Ralf Reilmann about quantitative motor assessment, and Dr Julie Stout about cognitive problems.

HDAC inhibitor drug protects memory in HD mice

HDAC inhibitor drug protects memory in HD mice

Dr Ed Wild on December 13, 2011

Thinking skills and disordered control of gene switching are both problems in Huntington's disease. Now Spanish researchers have linked the two, through a protein called CBP. And a 'histone deacetylase inhibitor' drug can prevent both problems in HD mice.

What do sheep brains have to do with HD?

What do sheep brains have to do with HD?

Dr Jeff Carroll on March 09, 2011

A leading HD researcher is studying how well sheep adapt to change. Believe it or not, this work could be important for the development of cutting-edge treatments for HD.

Memantine in HD: dose is everything

Memantine in HD: dose is everything

Dr Jeff Carroll on January 15, 2011

A drug used to treat the symptoms of Alzheimer’s disease might be beneficial in HD through altering the balance of good and bad messages coming into neurons. New research in HD mice suggests that low doses of memantine might be best, and hopefully a planned trial of low-dose memantine in HD patients will give us the answer.

Dimebon: disappointing in Alzheimer’s but might work in HD

Dimebon: disappointing in Alzheimer’s but might work in HD

Dr Jeff Carroll on December 23, 2010

Dimebon, a drug developed in Russia as an anti-allergy medication, is under investigation as a possible treatment to improve thinking problems in HD. There was disappointment when a recent large trial of Dimebon to treat Alzheimer’s disease in the USA showed no benefit, but hope remains in HD where the DIMOND trial is continuing across Europe.
