Impairment in emotional recognition — the process of identifying human emotion, most typically from facial expressions, particularly happy ones — seems to be linked with apathy in Huntington’s disease patients, a study showed. The article, “Apathy Associated With Impaired Recognition of Happy Facial Expressions…

The progressive death of brain nerve cells observed in Huntington’s disease is likely preceded by the retraction of their neurites — long projections that establish connections throughout the brain, a mouse study reveals. Understanding this mechanism, which is exacerbated during aging, stress, and neurodegenerative diseases, may open new avenues…

The loss of a type of nerve cell called a Purkinje cell in a brain region known as the neocerebellum is associated with the presentation of motor symptoms in Huntington’s disease, a study finds. The study, “Cerebellar degeneration correlates with motor symptoms in Huntington’s disease,” was published…

Late-onset Huntington’s disease (emerging at age 59 or older), progresses similarly to common-onset Huntington’s except that late-onset patients more frequently showed gait and balance problems as their first symptom, new research has found. This finding suggests that observing problems with gait and balance might be helpful in diagnosing late-onset Huntington’s disease…

A therapy for Huntington’s disease called INT41 was granted orphan drug designation by the U.S. Food and Drug Administration (FDA), bringing the treatment a step closer to being tested in a clinical trial. The announcement was made by Vybion Inc., a…
