HealthDay (10/16, Preidt) reports that, according to a study published online in the journal Clinical Psychological Science, adolescent “girls have more relationship-related stress than boys, which puts them at greater risk for depression.” After assessing “400 white and black American teens” for depression four times at intervals of approximately seven months, researchers found that “girls had more relationship-related stress (such as fights with parents or friends) than boys, which increased their risk for depression.”

Medwire News (10/16, Piper) reports that according to a 634-patient study published online Oct. 13 in the journal Bipolar Disorders, “experiencing verbal abuse in childhood has a lasting negative effect on the course of bipolar disorder [BD].” Researchers found that “verbal abuse in isolation was associated with an earlier onset of bipolar disorder and worse prognosis compared with no abuse.” What’s more, “the effect of verbal abuse on age of bipolar onset was related to its frequency, with patients reporting having experienced verbal abuse ‘occasionally’ or ‘frequently’ developing bipolar disorder earlier than those experiencing it ‘never’ or ‘rarely.’”

In print and in its “Well” blog, the New York Times (10/14, D5, Brody) reports that obsessive-compulsive disorder (OCD) “is often socially, emotionally and vocationally crippling.” But, when the condition is “properly treated, 60 percent to 85 percent of patients improve significantly and remain better for years, although booster sessions often are needed to maintain improvement.”

The most effective treatment technique is a form of cognitive behavior therapy called “exposure and response prevention…done once or twice a week for up to 30 hours total.” Patients with OCD may also suffer from anxiety and depression. Treatment is more effective if started sooner than later, and the condition will not go away on its own.

HealthDay (10/14, Preidt) reports that according to a study presented Oct. 7 at the Eating Disorders Association of Canada’s annual meeting, “eating disorders can begin before puberty and may be linked with other mental health issues.”

After evaluating some 215 eight- to 12-year-old children, researchers found that “more than 15 percent of the kids made themselves vomit occasionally, and about 13 percent had bulimic-like behaviors.” Notably, “psychiatric problems were present in 36 percent of the children’s families, and many of the children had mental health issues such as anxiety and mood and attention disorders, the study found.”

The New York Times (10/13, A10, Kolata, Subscription Publication) reports that according to research published online Oct. 12 in the journal Nature, “researchers created what they call Alzheimer’s in a Dish – a petri dish with human brain cells that develop the telltale structures of Alzheimer’s disease.”

By so doing, “they resolved a longstanding problem of how to study Alzheimer’s and search for drugs to treat it; the best they had until now were mice that developed an imperfect form of the disease.” Essentially, investigators at the Massachusetts General Hospital grew human neurons in a gel. The neurons had been given “genes for Alzheimer’s disease.”
