Differences In Brain Function Found For Attention Deficit Disorder
Researchers found a clear difference in brain activation between boys with ADD and those without, specifically in the striatal region involved in motor control. Ritalin improved impulse control in both groups but had different effects on brain activity in those with and without ADD.
Study Finds Heart Attack Symptoms -- Except Chest Pain -- Are Often Ignored
A study found that despite high awareness of chest pain as a heart attack symptom, many people are unaware of other critical symptoms like arm numbness and shortness of breath. The research highlights the need for targeted education about complex heart attack symptoms to reduce delay in seeking medical care.
Scientists Finger A Molecular Kingpin In Body's Response To Cigarettes
Scientists have identified a specific gene, the AH receptor, as a vital link in the chemical cascade that causes cancer when exposed to cigarette smoke. The study found that mice without this receptor showed no damage from cigarette smoke, suggesting it plays a crucial role in controlling gene damage.
Childhood Loss Linked To Later Health Problems
Young children who lose a parent or experience poor family relationships may be more likely to develop increases in blood pressure and disruptions in hormone release later in life. Research suggests that early loss or lack of good quality family relationships may have a 'permanently' increased overall cardiovascular activity among adults.
Friends, Family Can Help Heart Patients Avoid Depression
Researchers found that heart patients with high levels of social support show fewer symptoms of depression, while those with low social support tend to have higher levels of depression. Interventions that decrease hostility and increase social support may also benefit heart disease patients.
"Job Strain" Linked To High Blood Pressure, Heart Disease Risk
A large longitudinal study found that job strain is a significant risk factor for high blood pressure and heart disease. Men with highly demanding jobs experience higher blood pressure, while those who move to less demanding roles see their blood pressure decrease over time.
