Blood Tests Diagnose Depression?

Published by:

Blood Tests Diagnose Depression? New blood tests to diagnose depression may lead to better treatment and less stigma. Diagnosing teenage depression the way it’s done now — by letting teens take the Beck Depression Inventory (BDI) and asking them to describe their own symptoms, and then relying on psychiatrists to interprete these — can be tricky since mood swings are normal during the adolescent years.

But diagnosing depression in teenagers is urgent because these youngsters are highly vulnerable to the mental disorder: Teenage years are the prime time for depression to start and rates of major depressive disorders jump from two to four percent in pre-adolescent kids to 10 to 20 percent by late adolescence.

It’s been less than one month since two studies — conducted independently by researchers in the United States and Italy — concluded that bariatric surgery may be the best treatment for obese people who suffer from type 2 diabetes.

Now a new study, conducted by yet another institution, also in Italy, comes to the same conclusion. All three studies found that patients who underwent weight loss surgery enjoyed improved diabetes outcomes compared to patients who received standard therapy and medications to control diabetes.

Obesity and diabetes are two major health challenges across the world, and for both diseases, the increasing prevalence has reached epidemic proportions. Even as the prevalence of diabetes in the U.S. and across the world is surging in parallel with obesity’s rise, the link between the two conditions is also well established: Some 80 percent of the 23 million adult Americans who have type 2 diabetes are either overweight or obese.
