Stroke risk greater for older women with atrial fibrillation
In a study that examined use of the anticoagulant medication warfarin and risk of stroke following a diagnosis of atrial fibrillation in older patients, women, especially those 75 years or older, had a higher risk of stroke than men, regardless of their risk profile and use of warfarin, suggesting that current anticoagulant therapy to prevent stroke might not be sufficient for older women.

Depression - now blood test can diagnose depression in teens
A breakthrough approach that allows an objective diagnosis of major depression in teens by measuring a specific set of genetic markers found in a patient's blood. The current method of diagnosing depression is subjective. It relies on the patient's ability to recount his symptoms and the physician's ability and training to interpret them.

Earlier sign of autism can be noticed in 6 months old infants
In their first year of life, babies who will go on to develop autism already show different brain responses when someone looks at or away from them. Although the researchers are careful to say that the study, reported in the Cell Press journal Current Biology, is only a first step toward earlier diagnosis, the findings do suggest that direct brain measures might help to predict the future development of autism symptoms in infants as young as six months.

Age for diagnosis and treatment of ADHD in children expands 4 to 18
Now it possible to diagnose and manage ADHD in children from ages 4 to 18 (the previous AAP guidelines, from 2000 and 2001, covered children ages 6 to 12). The new guidelines describe the special considerations involved in diagnosing and treating preschool children and adolescents.

Local biosurveillance data can improve individual patient care
By taking local biosurveillance data into account when assessing patients for communicable diseases, doctors may be able to make better diagnostic decisions, according to researchers at Children's Hospital Boston.

People seek early diagnosis of Alzheimer's disease
Results of an international survey reveal that over 85% of respondents in the five countries surveyed say that if they were exhibiting confusion and memory loss, they would want to see a doctor to determine if the cause of the symptoms was Alzheimer's disease. Over 94% would want the same if a family member were exhibiting the symptoms.

Cancer mortality rates higher in men than women
Overall cancer mortality rates are higher for men than women in the United States. Men are more likely to die from cancer than women. For many cancers, men have poorer survival than women but the differences are slight, and this is due to the greater frequency of cancer diagnosis, rather than poorer survival once the cancer occurs.

Men may have greater allergy risk than women
