Re-energizing Mitochondria to Treat Alzheimer’s Disease

Alzheimer’s nerve cells manifest a decrease in the connections between nerve cells, called synapses, shown here within the blue circles. Half the synapse is marked with a red fluorescent stain and the other half with a yellow stain. Credit: Scripps Research

Nerve cells in the brain demand an enormous amount of energy to survive and maintain their connections for communicating with other nerve cells. In Alzheimer’s disease, the ability to make energy is compromised, and the connections between nerve cells (called synapses) eventually come apart and wither, causing new memories to fade and fail.

A Scripps Research team, reporting in the journal Advanced Science, has now identified the energetic reactions in brain cells that malfunction and lead to neurodegeneration...
