Sometimes, parents are too busy themselves to notice the distress signs. Depression may affect any child who suffers from stress. This is also a hereditary illness. It runs in families and breaks out when there is a combination of factors like environmental stress and brain chemistry. Some brains can't cope with high stress levels and there is chemical imbalance in the brain.
Medical treatment includes anti-depressants to correct the chemical imbalance.
On the domestic scene, parents can help by paying more attention to their children. Discuss the child's academic work, school, friends,feelings, loves and hates. If they reveal some sadness, offer solutions or stand by them to give moral support. Initial combat of depression can involve the family physician. If he recommends further professional help, then seek a psychiatrist.
