The Science Daily article entitled Body dysmorphic disorder patients who loathe appearance often get better, but it could take years discusses the disorder as highlighted in the Journal of Nervous and Mental Disease (JNMD).
The JNMD article reports the results of the longest-term study so far to track people with body dysmorphic disorder (BDD). The study was conducted by researchers at Brown University and Rhode Island Hospital. The good news? The researchers “found high rates of recovery, although recovery can take more than five years.”
This is a small study with only 15 BDD patients who were followed over an eight-year span. An excerpt:
After statistical adjustments, the recovery rate for sufferers in the study over eight years was 76 percent and the recurrence rate was 14 percent. While a few sufferers recovered within two years, only about half had recovered after five years.
The subjects were a small group diagnosed with the disorder out of hundreds of people participating in the Harvard/Brown Anxiety Research Project (HARP). Study co-author Martin Keller, professor of psychiatry and human behavior and principal investigator of the HARP research program which has been ongoing for more than 20 years, said that because the BDD sufferers were identified through this broader anxiety study, rather than being recruited specifically because they had been diagnosed with BDD, they generally had more subtle cases of the disorder than people in other BDD studies. In comparing the HARP study with the prior longitudinal study of BDD, it is possible that the high recovery rate in the HARP study is due to participants having less severe BDD on average.
About body dysmorphic disorder:
— In its simplest definition, it is an obsessive preoccupation with a slight, imperceptible, or actually nonexistent anatomic irregularity to the degree that it interferes with normal adjustment within society. Read more »

Scientists know that our perceptions about taste and texture drive our food preferences. They know quite a lot about the role of taste in this regard, and the results of some recent experiments have shed new light on the role of texture as well, particularly as it relates to foods containing starch.
Starch is a major component of potatoes, rice, corn, wheat and the enormous variety of foods derived from them. It is also added to many other products from maple syrup to pudding. In fact, starch accounts for 40 to 60 percent of the calorie content in the average Western diet, and more than that in many Asian and third-world diets.
Humans begin digesting starch in the mouth, where the salivary glands secrete an enzyme known as amylase. This enzyme breaks down starch and other complex carbohydrates into simpler sugar molecules which end up being absorbed from the small intestine into the bloodstream. Read more »

Not as often as you think, even though Medicare may be willing to pay for it every two years. Via Science Daily:
Now a new study led by Margaret L. Gourlay, MD, MPH of the University of North Carolina at Chapel Hill School of Medicine finds that women aged 67 years and older with normal bone mineral density scores may not need screening again for 10 years.
“If a woman’s bone density at age 67 is very good, then she doesn’t need to be re-screened in two years or three years, because we’re not likely to see much change,” Gourlay said. “Our study found it would take about 16 years for 10 percent of women in the highest bone density ranges to develop osteoporosis. That was longer than we expected, and it’s great news for this group of women,” Gourlay said.
The researchers suggest that for T scores > -1.5, repeat testing needn’t be done for 10 years. Women with T scores between -1.5 and -2.0 can be re-screened in 5 years, and those with T scores below -2.0 can have every other year testing as is done now.
To be honest, I’ve been spacing out bone density testing in woman with good baseline scores for some time, but not knowing how long I can go. This is great information for me and for my patients.
