Alzheimer and its cause found

"Cell biologists led by Utrecht University’s Professor Casper Hoogenraad have discovered the protein that may be the crucial traffic regulator for the transport of vital molecules inside nerve cells. When this traffic regulator is removed, the flow of traffic comes to a halt. The resulting ‘traffic jams’ are reported to play a key role in neurodegenerative diseases such as Alzheimer and Parkinson’s disease." from https://www.uu.nl/en/news/cell-biologists-discover-crucial-traffic-regulator-in-neurons
