Traumatic events have long-term impact on children

A recent study found that nearly all children who experienced a traumatic event exhibited acute stress symptoms, with roughly half continuing to experience post-traumatic stress symptoms after 18 months. The researchers also discovered that indirectly-exposed children were at risk of developing full-blown post-traumatic stress disorder.

Depression alters immune systems by decreasing physical activity

Women with mild to moderately severe depression exhibit altered immune systems due to lower levels of physical activity, according to a recent study. The researchers found that physical activity accounted for up to 63% of the differences in specific immune functions between depressed and non-depressed women.

Depression's role in sudden cardiac death downrated

New research suggests that depression may not play a significant role in increasing the risk of sudden cardiac death after an acute heart attack. The study found that increased social contact with family and friends during the time of the heart attack may actually heighten the risk, while participation in pleasurable activities lowers it.

Work overcommitment impacts the heart

Research from The Netherlands reveals that individuals with high work overcommitment scores may be predisposed to cardiovascular disease due to an impaired natural blood clot-dissolving system. This association suggests a potential physical mechanism behind the observed link between work-related stress and heart disease.
