May 26, 2010— -- People with Olfactory Reference Syndrome feel they are the elephant man of body odor -- so repugnant to society that no one would ever want to stand near them never mind go on a date.

Often sufferers fall into depression and shut out the world because of their stench. But doctors say the stench is entirely in their head.

Instead of a glandular problem, these people actually suffer from Olfactory Reference Syndrome (ORS).

"A lot of them got to see GI doctors, surgeons, or dentists and dermatologists -- one patient in our study had their tonsils removed because they thought that their breath smelled so bad," said Dr. Katharine Phillips, a psychiatrist at Rhode Island Hospital and a professor of psychiatry at Brown University.

"More than one third of our patients received these types of treatments and in no case did the treatment help the ORS symptoms," she said.

Phillips presented a study on 20 people with ORS -- one of the few studies in the literature -- at the American Psychiatric Association meeting in New Orleans Tuesday.

She found the relatively unknown syndrome wrought havoc on people's lives. Sixty-eight percent of people with ORS) have thoughts of suicide, and 32 percent attempt it.

On average they spent three to eight hours a day obsessively thinking about their various odors that no one else can smell. Forty percent of people in the study spent at least a week housebound for fear that others could smell them.

The imagined source of the smell can come from almost anywhere, but most commonly 75 percent of people thought their stench came from bad breath. Sixty percent of people in the study thought body odor from their armpits would bother others, and 35 percent thought there were odors from their genitals.

Phillips said patients can be so delusional about the smell that they are often misdiagnosed as schizophrenic. Her study found 85 percent of the subjects had delusional beliefs that they had overpowering body or chemical odors. The fact that 15 percent of people had an idea that they really didn't smell convinces many that the problem is a mental one, not an extreme sensitivity to a specific odor.
