Huntington's disease may result from defects in support cells called glia, say researchers. The discovery may put new therapies in reach.

Artificial intelligence can check blood samples to predict and explain the progress of neurodegenerative diseases like Alzheimer's, researchers report.

Research with mice shows how sensory and motor signals have different paths and effects on our behavior, which could lead to Parkinson's treatments.

The confirmation that the brain's support cells are key contributors to Huntington's disease offers a new path to potential treatments.
