Huntington’s Patients with Low Perceived Psychological Distress May Have Weaker Social Cognitive Skills

Patients with Huntington’s disease with low levels of perceived psychological distress may have weaker social cognitive skills, according to a new study. However, researchers think that this association (self-reporting of psychological distress and social cognitive test performance) may be due to apathy and/or impaired insight, which are common in this disease.

Protein May Prevent Neuron Death in Huntington’s Patients, Study Finds

A protein called Nrf2 can help maintain healthy levels of proteins associated with neurodegenerative diseases, including Huntington’s disease, thereby protecting neurons from death, according to new research. Results of the study, “Nrf2 Mitigates LRRK2- And α-synuclein–induced Neurodegeneration By Modulating Proteostasis,” were published in the journal PNAS. Neurodegenerative disorders…

Judgment Task, Called Reversal Learning, Diminishes as Huntington’s Advances, Study Suggests

The ability to apply reversal learning, which involves adapting behavior according to changes in stimulus-reward situations, appears to be diminished in patients with Huntington’s disease and to worsen as the disease progresses, according to new research. This study, “Reversal Learning Reveals Cognitive Deficits And Altered Prediction Error Encoding In The Ventral Striatum…

Huntington’s Patients’ Inability to Recognize Facial Emotions May Be Due to Multi-brain-area Dysfunction, Study Says

Huntington’s disease patients’ inability to recognize people’s emotions from their facial expressions appears to be linked to dysfunction in more than one area of the brain, according to a study. The brain areas include “emotion–related regions, such as front-striatal networks and limbic areas, and regions associated with visual processing,” according…
