Windmills, Tulips, and Kimchi: A Dutch intelligence researcher studies Alzheimer’s disease in Gwangju

Alzheimer’s is a nasty brain disease. The nerves in the brain are slowly rotting away until they die. It becomes increasingly difficult for the brain cells to communicate with each other, so the processing of information by the brain slows down dramatically. This means the scores on IQ tests get lower and lower, and even the simplest tasks previously become too difficult.
