As reported in Discover Magazine, Saxena took a scientific approach to understanding the minds of such hoarders. He devised a study comparing the brain scans of those with no disorders, those with Obsessive-Compulsive Disorder (OCD) (characterized by a compulsion to act on anxieties) and those with Obsessive-Compulsive Hoarding. He and his team were able to glean some interesting findings. "In the brain of compulsive hoarders was a unique, distinct pattern. They did not have the typical areas of elevated activity we saw in all the other OCD patients, instead they actually had low activity in certain parts of the brain that were involved in visual-spatial orientation, and in other parts of the brain involved in tension, motivation and decision-making."
