Which theory about the cause of depression is supported by research?
a. Heredity or genetics
b. Altered neuroendocrine function
c. Psychosocial factors
d. Neurotransmitter level imbalance
D
Research suggests that depression may be caused by an imbalance of brain chemicals called neurotransmitters (e.g., serotonin, dopamine, and norepinephrine). Communication between neurons in the brain occurs by the movement of these chemicals across a small gap called a syn-apse. Neurotransmitters are released from one neuron and cross the synapse where they may be accepted by the receptor sites on the next neuron. When neurotransmitter levels decrease or be-come imbalanced, the neurons may be less able to communicate with each other, which may lead to depression and other mood changes.
