For decades, a Parkinson’s diagnosis meant accepting inevitable decline – trembling hands, shuffling steps, and lost independence. This merciless disease has stalked millions, with no cure in sight. But recently, CUHK scientists have developed a single-shot gene therapy that can stop Parkinson's in its tracks. Their microscopic weapon infiltrates the brain, stopping rogue proteins from forming deadly clusters that trigger neurodegeneration. The research offers tangible hope to transform an unstoppable disease into a manageable one.
