Although DAT scans are often claimed to show a loss of dopamine producing cells, DAT scans can instead show a reduced activity of the dopamine producing cells. Most of the cells are there. They just aren't as active as they should be. In typical PD the activity is about 25%. In severe PD the activity can be less than 10%.The level of activity is constantly changing, which is why symptoms can fluctuate.
