Alzheimer's disease (AD) is a progressive brain disorder which causes memory and thinking problems. The exact cause of AD is unknown. Researchers believe mitochondria (the part of your cells that produces energy) might be linked to symptoms of AD. Some studies have shown that patients with Alzheimer's disease have reduced mitochondrial activity or have fewer mitochondria present in neurons. In this study, it is believed that by targeting mitochondria, we might learn more about its influence on AD symptoms.
