Having a schoolmate commit suicide significantly increases the chance that a teenager will consider or attempt suicide themselves, according to a new study in the Canadian Medical Association Journal (CMAJ).
The study surveyed more than 22,000 Canadian children aged 12 to 17. They were asked if anyone in their school, or anyone they knew personally had died by suicide and if they had seriously considered attempting suicide themselves in the past year. The researchers found that the risk of suicide was magnified even if the child did not know the deceased student personally.

Attention-deficit/hyperactivity disorder, or ADHD, is often considered something children outgrow. But researchers say the disorder can carry over into adulthood.
A new study published in this week's Pediatrics journal finds that about a third of those diagnosed as children continue to have ADHD as adults, and more than half of those adults have another psychiatric disorder as well.
Suicide rates were nearly five times higher in adults who had childhood ADHD compared to those who did not, according to the study. Researchers aren't exactly sure why; they speculate that problems associated with childhood ADHD, such as lower academic achievement and social isolation, make people more prone to life issues as adults.

Drinking coffee and tea rich in antioxidants may not lower your risk of dementia or having a stroke, according to a new study published Wednesday in the online journal Neurology.
The study may call into question other research suggesting a diet high in antioxidants helps reduce the risk of dementia and stroke.
Researchers followed approximately 5,400 people aged 55 years and older for nearly 14 years. The participants had no signs of dementia when they began the study and most had never had a stroke. They were questioned about how often they ate 170 foods over the course of the past year and they were divided into three groups based on the levels of antioxidants in their diet - low, moderate or high.

It's a heated question: should women take antidepressants during pregnancy? Some experts argue for it and some against, but a new study may ease the minds of women facing the decision.
Researchers say taking a common type of antidepressant does not increase the risk of having a stillborn child or losing an infant early in life. The study was published in this week's Journal of the American Medical Association (JAMA).
"It does strengthen the view that these meds are safer than we once thought," explains Dr. Jennifer Payne, director of the Women's Mood Disorders Center at Johns Hopkins School of Medicine in Baltimore. FULL POST

Sleepy school children make crabby classmates, while students who get plenty of sleep are better behaved, according to a new study published this week in the journal Pediatrics.
"Extending sleep opens the door to an effective, feasible way to improve children's health and performance," says study author Reut Gruber, director of the Attention Behavior and Sleep Lab at the Douglas Research Center in Quebec, Canada.
Gruber and his colleagues wanted to find out if the behavior of elementary school children was affected by how much sleep they got. The researchers, with the permission of parents, enrolled 34 students ages 7 to 11 in the study. These were healthy kids who didn't have sleep problems or behavior or academic issues.

Teenagers are often characterized as over-emotional, prone to outbursts that confuse their parents and leave teachers reeling.
But a study published in the July issue of the journal Archives of General Psychiatry says 1 in 12 adolescents may in fact be suffering from a real and severe anger problem known as intermittent explosive disorder (IED).
Study author Katie McLaughlin, a clinical psychologist and psychiatric epidemiologist, says IED is one of the most widespread mental health disorders - and one of the least studied.
"There's a contrast between how common the disorder is and how much we know about it," she said.

For many couples, the division of household chores is a hot-button issue that stirs up questions about the essential fairness, or unfairness, of their relationship.
Chores can stir up emotions, too. Unpaid domestic work can be physically demanding, monotonous and isolating, and when one partner - usually the woman - is responsible for the lion's share of the work, research has shown, that partner's mental health can suffer.
This fact was largely borne out in a new study of more than 700 Swedish men and women, published this week in the journal PLoS ONE. Predictably, the researchers found that 42-year-old women bear a greater burden of housework than their male counterparts, and also that they're more likely to experience restlessness,nervousness, anxiety and other symptoms of psychological distress.

Receiving psychotherapy over the phone is showing promise for people with depression, according to new research. A study published Tuesday found patients counseled over the phone were less likely to drop out of treatment compared to those who got face-to face counseling. Researchers also found people who talked to their therapist on the phone got better at the same rate as those who spent time on the counselor's couch.
"This research gives us a pretty clear indication that providing therapy via technology can be a useful strategy," says Lynn Bufka, assistant executive director, practice research and policy at the American Psychological Association.
Researchers at Northwestern University in Chicago conducted the study which was the first large trial comparing face-to-face therapy with telephone therapy. Their findings were published in the Journal of the American Medical Association.

Imagine the incessant, grating sound of buzzing in your ears - or constant beeping, whistling, dripping, or clicking. Imagine the chatter of crickets or birds resonating in your head all day long.
Then realize that there are no actual birds or crickets. No dripping faucet. No clicking or whistling happening in the vicinity.
That is a small glimpse of life with tinnitus: The perception of sound, that doesn't exist, manufactured by the brain.
"I hear tree frogs and crickets and bugs, and really loud noise on top of that," said Ginny Morrell, 60, who has suffered with tinnitus for two years. "It started one day and never went away. It never wavers, 24 hours a day."

How does a parent know if their child or teen is experiencing normal adolescent sadness or moodiness or - a more serious form of depression? The answer may one day lie in a simple blood test, if the results of a new early study are confirmed in larger populations.
The results are published in Translational Psychiatry.
Early-onset major depressive disorder is a mental illness that affects people under 25. While about 2 to 4% of cases are diagnosed before adolescence, the numbers skyrocket to 10-25% with adolescence, explains lead researcher Eva Redei, professor of psychiatry and behavioral sciences at Northwestern University Feinberg School of Medicine.
