Depression: Recognizing the Physical Signs Depression seems to be related to improper regulation in nerve cell networks or pathways that connect the brain areas that process emotional information. Some of these networks also process information for sensing physical pain. So many experts think that depression can make you feel pain differently than other people.

What causes depression? Certain areas of the brain help regulate mood. Researchers believe that — more important than levels of specific brain chemicals — nerve cell connections, nerve cell growth, and the functioning of nerve circuits have a major impact on depression.mygdala: The amygdala is part of the limbic system, a group of structures deep in the brain that's associated with emotions such as anger, pleasure, sorrow, fear, and sexual arousal. The amygdala is activated when a person recalls emotionally charged memories, such as a frightening situation.

Dopamine May Play New Role in Depression July 28, 2005 -- A chemical in the brain normally associated with feelings of happiness and pleasure may also raise the risk of depression. Researchers say they've found a new way in which prolonged exposure to the chemical messenger dopamine may play a role in depression as well as drug addiction. If confirmed by further studies, they say the discovery could lead to a new understanding of these complex disorders as well as better treatments.

Can Depression Cause Memory Loss? Electroconvulsive therapy (ECT) can cause memory loss. ECT alters brain chemistry, which can reverse the symptoms of depression and other mental illnesses. If you have ECT, your doctor will perform it while you’re under general anesthesia. During ECT, your doctor sends small electric currents through your brain, triggering a brief seizure. People can experience confusion and short-term memory loss after receiving ECT treatments.

Is Depression Just a Chemical Imbalance? Depression is at least as correlated with these things as it is with brain chemicals. In terms of brain chemicals, the only conclusive thing we can say is that depression is associated with lower levels of certain chemicals in the brain, not that depression is “caused by” by the levels of those chemicals.

Neurotransmitters are chemicals that relay messages from neuron to neuron. An antidepressant medication tends to increase the concentration of these substances in the spaces between neurons (the synapses).

Stress and Depression Both types of stress lead to overactivity of the body's stress-response mechanism. Sustained or chronic stress, in particular, leads to elevated hormones such as cortisol, the stress hormone, and reduced serotonin and other neurotransmitters in the brain, including dopamine, which has been linked to depression.

Causes of Major Depression The wide range of potential causes has lead to the development of numerous depression treatments. Biological Cause of Major Depressive Disorder. A change in brain activity is almost always associated with major depressive disorder. There is decreased activity in the left frontal lobe during depression and a rise in activity following stabilization of mood. These discrepancies between over-active and under-active regions of the brain are at the biological cause of major depressive disorder. Neurotransmitters Could Cause Depression The release and reuptake of neurotransmitters (serotonin, norepinephrine, and dopamine) in the brain is linked to a person’s mood.
