Gene linked to Alzheimer’s disease Impairs Memory by Disrupting brain’s ‘Playback System’

Mice with apoE4 had fewer ripples than mice with the normal apoE3 protein, and they had less slow gamma activity during the ripples. Based on these results, the scientists questioned whether these differences in activity affected the ability to form and replay memories. Image is for illustrative purposes only.

Scientists at the Gladstone Institutes have discovered how the major genetic risk factor for Alzheimer’s disease causes memory impairment. A specific type of brain activity important for memory replay is disrupted in mice with the E4 version of the apolipoprotein E (apoE4) gene, which may interfere with memory formation...
