FRIDAY, Aug. 1 (HealthDay News) -- Scientists have long observed a link between depression and heart disease. Now there's research to help pinpoint the symptoms of depression that may signal cardiovascular trouble.

A study suggests that people who suffer from depression, especially certain physical symptoms such as loss of appetite, sleep problems or fatigue, may be at risk of developing heart disease.

(HealthDay News) - Children are by no means immune from the emotions and stressful times that can contribute to depression.

Here's a list of possible warning signs of depression in children, courtesy of the American Academy of Family Physicians:

* Loss of appetite, or weight loss.
* Loss of desire, among young children, for playtime.
* Lack of confidence or self-esteem.
* General disinterest in themselves, family members or once-favored activities.
* Not wanting to go to school.
* Significant changes in sleeping or eating habits.
