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.

EU Calls for Research Proposals on Common Links in Neurodegenerative Diseases

The European Union is inviting researchers in 20 countries to work together on projects focusing on Huntington’s disease (HD) and other degenerative diseases. The agency sponsoring the effort, the Joint Programme — Neurodegenerative Disease Research (JPND), said in a press release that neurodegenerative conditions have become a global health epidemic, with heavy economic…

Mitochondrial Energy Processes in Huntington’s May Be Normal After All

Mitochondrial abnormalities may not contribute to the degeneration of neurons in the striatum in patients with Huntington’s disease, according to a study that provides evidence contradicting several earlier findings. The study explored mitochondrial processes in a mouse model of Huntington’s disease and found that mitochondria from the striatum — the…

Targeting Astrocyte Brain Cells That Turn Toxic Could Help Treat Huntington’s, Other Diseases

A subtype of brain cells called astrocytes could be contributing to the death of neurons in neurodegenerative diseases such as Huntington’s disease (HD), according to a new study published in the leading scientific journal Nature. This new finding presented in a report titled “Neurotoxic reactive astrocytes are induced by activated microglia” is important because it provides opportunities for scientists to develop new treatment approaches to treat Huntington’s and other neurodegenerative diseases.

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…
