A single-cell organism’s accidental encounter with a bacterium 1.5 billion years ago gave rise to the mitochondria, the powerhouse of our cells. This ancient event has significant implications for understanding Parkinson’s disease, a neurodegenerative disorder linked to dopamine deficiency. Recent research suggests that mitochondrial dysfunction may play a key role in its development. The discovery highlights the importance of mitochondria, not just as energy-producing structures, but also as cellular “motherboards” that carry genetic information from parents to children. While there is no known treatment for Parkinson’s, early detection and prevention strategies, including regular exercise, diet rich in fruits and vegetables, stress reduction, and caffeinated drinks, may help mitigate its effects.
