Obviously, no two individuals become depressed in the same way. For example, one might become depressed from stress while another person might have a genetic predisposition to the disease. To add to the complication of depression, there are various types of the illness. Treatment for depression is prevalent and given the time-effective. Scientific findings have found neurotransmitters, norepinephrine, dopamine, and serotonin most involved with depression.
Findings propose that when one is in a depressed state, the neurotransmitters wane.
For example, serotonin helps you feel relaxed and content. But when serotonin levels drop one might become more agitated, anxious, impulsive, and sad. Suppose you are taking an exam and you reach an unexpected snag. As you feel yourself getting anxious, neurons send serotonin to neuro-receptors. When the serotonin hits the neuro-receptor, it passes along the message that you should remain calm.
