A breakthrough study has uncovered a hidden player in Parkinson’s disease—24-OHC, a cholesterol metabolite that fuels the spread of harmful protein clumps in the brain. Researchers found that high levels of this metabolite accelerate neuron damage and motor dysfunction,

Parkinson’s disease may be linked to a cholesterol by-product that helps harmful protein clumps spread in the brain, a breakthrough study has revealed. Researchers discovered that having excess levels of the metabolite speeds up neuron damage and motor decline.
