Researchers have discovered a molecule that accumulates with age and inhibits the formation of new neurons. The finding might help scientists design therapies to prevent age-related cognitive decline.

A study at the University of Toronto on a handful of people with suspected mild Alzheimer’s disease (AD) suggests that a device that sends continuous electrical impulses to specific “memory” regions of the brain appears to increase neuronal activity.
Results of the study using deep brain stimulation, a therapy already used in some patients with Parkinson’s disease and depression, may offer hope for at least some with AD, an intractable disease with no cure. Delete the scoop?

Karl Deisseroth, MD, PhD, a professor of bioengineering and of psychiatry and behavioral sciences at Stanford University, and postdoctoral scholar Melissa Warden, PhD, have isolated the neurons that carry the split-second decisions to act, from the higher brain to the brain stem. In doing so, they have provided insight into the causes of severe brain disorders such as depression.
