In laboratory experiments, scientists treated damaged neurons with specific fatty acid supplements and found that within just 48 hours, the cells regained their energy production and normal activity.

"We've shown that healthy neurons rely on fats for fuel, and when this pathway fails in conditions like HSP54, it may be possible to repair the damage and reverse the neuropathologies."

These studies will determine whether similar approaches could eventually be used in humans, and whether this fat-based energy system might also play a role in treating other neurological diseases that currently lack effective therapies.

Researchers from the University of Chicago Medicine and Columbia University discovered that eating more fruits and vegetables during the day was linked to more restful, higher-quality sleep later that night.

For the research, healthy young adults logged their daily food intake using an app and wore a wrist monitor that tracked their sleep.
