Scheduling a meal time and following the same improves motor activity and sleep quality, according to new research published in eNeuro.
These findings suggest that eating on a strict schedule could improve quality of life for patients with neurodegenerative diseases for which there are no known cures.
Christopher Colwell and colleagues used a well-studied mouse line that models the genetic cause and symptoms of Huntington's disease, including sleep disruptions that appear to be a general feature of neurodegenerative disorders.
In addition, these mice showed improved heart rate variability, a marker of cardiovascular health, and more typical gene expression in the striatum, a brain region involved in motor control that is susceptible to degeneration in Huntington's disease.
This study, which manipulated the availability but not the quantity of food, points to the time of feeding as an additional environmental signal that might work in conjunction with light to regulate the body clock.
