Researchers have identified a key molecular interaction that accelerates Parkinson's disease by damaging the brain's energy systems. This interaction leads to brain cell damage. Scientists have designed a new treatment that stops this harmful process, protects cells and restores their function. In laboratory and animal models, this approach improved movement and cognitive performance. At the same time, it reduced inflammation in the brain. The findings point to a new generation of therapies targeting the root cause of Parkinson's disease, not just the symptoms.
