What Chemical In The Brain Causes Depression

And just like those illnesses depression is not something a person can snap out of Its believed that a combination of genetic biological environmental and psychological factors cause depression. While serotonin dopamine and norepinephrine have long been considered the big three neurotransmitters involved in depression recent research suggests that what causes depression may be more complicated than just having not enough or too much of these neurotransmitters in certain parts of the brain.

Depression Types

Other chemicals called hormones may affect the delicate balance of chemicals in the brain.

What chemical in the brain causes depression. Activity in the amygdala is higher when someone experiences depression.

Forest Pharmaceuticals state on their website that research indicates the cause of depression is a chemical imbalance most notably serotonin imbalance. Schildkraut suggested norepinephrine was the brain chemical of interest for depression when he presented the catecholamine hypothesis of mood disorders. When your brain gets flooded with cortisol for long periods of time it can slow or stop the growth of new neurons in the hippocampus.

For example researchers point out that if depression were solely due to chemical imbalances treatments that target neurotransmitters such as selective serotonin reuptake inhibitors.

Some of the neurotransmitters believed to be linked to depression are serotonin norepinephrine and dopamine. However the causes of this imbalance are not clearly known. Evidence indicates that brain biochemistry is a significant factor in depressive disorders.

Schildkraut proposed depression occurred when there is too little norepinephrine in certain brain circuits. The potential relationship between depression and hormones focuses on 3 main areas. It was claimed that mental illness including anxiety disorder was caused by an imbalance of neurotransmitters in the brain.

Depression is a real illness just like diabetes or heart disease. However the role that brain chemistry plays in depression is significant. Neurotransmitters are chemicals that carry signals to.

Depression medication controls depression by increasing amounts of different brain chemicals like serotonin norepinephrine and dopamine. Part of the brain called the hippocampus releases the hormone cortisol when youre stressed which includes episodes of depression. Although dopamine was thought initially to be crucial to the reward system in the brain and the neurons that control feelings related to pleasure it more directly.

Examples include norepinephrine and serotonin. In addition they assert Lexapro an antidepressant is thought to work by restoring the brains chemical balance Jarrett 2015. They never indicate what exactly that balance is.

In the 1960s Joseph J. Chemical changes in the brain may contribute to the symptoms of the disease. For instance the imbalance of serotonin in your brain can cause depression.

Someone with depression often has an imbalance of neurotransmitters. The fight-or-flight response the thyroid hormones and the sex hormones. Changes might include fluctuations in the concentration of neurotransmitters or damage to nerve cells.

The amygdala is a structure deep within the brain that is associated with certain emotions such as sorrow fear anger and pleasure. Neurotransmitters are natural chemicals that help ease the communication between your nerve cells. Depression is biological and largely brain-based.

These chemical reactions affect your mood.
