The discovery opens up for new potential methods of early intervention . Alzheimer’s disease is the most common form of dementia and strikes about 20,000 people in Sweden every year. Researchers now show that a metabolic increase in the mitochondria , the cellular power plants, is an early indicator of the disease.  Per Nilsson.

The increase in metabolism in young mice was followed by synaptic changes caused by disruption to the cellular recycling system (a process known as autophagy ), a finding that was awarded the N obel Prize in
