Cells in the brain communicate with each other via electric signals and by using messenger substances, called "neurotransmitters." If there are too few neurotransmitters, communication is disrupted, which causes the symptoms of depression and anxiety.

Depression strikes people of all ages, backgrounds, and ethnic groups. Depressive disorders affect about 34 million American adults.
