Steven Loch doesn’t know why his obsessive-compulsive disorder subsides while he’s dancing, but he’s grateful for the relief it provides from the “torture” of his symptoms. In a compelling interview with Brendan Kiley of The Seattle Times, Loch gives a candid description of the disturbing thoughts that cause his unpleasant behavior and prompted him to find treatment at psychiatric hospitals.

Kiley’s excellent article also features an explanation by Dr. Sam Zinner, a specialist in neurological development, of OCD’s medical origins.

“The human brain has a cluster of neurons called the basal ganglia. Put together, he explained, they’re the size of a walnut, and take in the deluge of cognitive, motor, memory, emotional and sensory information that floods through our brains when we, say, kick a soccer ball or watch out for poisonous snakes while walking through a swamp. The basal ganglia are supposed to filter out all the extraneous noise so we can focus on the task at hand. “In every picosecond of time,” Zinner said, “the basal ganglia have to decide what is relevant, what not to block out so you can survive.”

But the basal ganglia in brains with OCD — and related conditions, including Tourette syndrome and attention deficit hyperactivity disorder (ADHD) — are, in his words, “leaky filters.” Those leaks lead to information overload and behavior that, to the casual observer, might seem odd — like compulsively touching a magazine three times before picking it up, or hiding on a bathroom floor in costume during a ballet performance to avoid horrifying, intrusive thoughts.”
