Nerve Cell Communication And Depression
Neurotransmitters facilitate communication between nerve cells and target cells. Studies have linked changes in neurotransmitter activity with symptoms of depression.
A review of these studies found that reduced or abnormal activity of neurotransmitter systems within parts of the limbic systems may cause depression and anxiety.
However, the exact causes of depression and other mental health conditions remain unclear. Biological, psychological, and environmental factors may all play a part.

What are the signs of a chemical imbalance?
According to the American Psychiatric Association, an imbalance in specific brains chemicals , namely an imbalance with serotonin and dopamine, can produce depression, bipolar disorder, schizophrenia, delusions, and other psychiatric conditions in some people. In a person with major depressive disorder, symptoms of a chemical imbalance or a dysfunction in their serotonin system include:
- Persistent feelings of sadness, despair, or hopelessness
- Loss of interest in the activities that you used to enjoy
- Fatigue and low energy
- Sleep difficulties
- Trouble concentrating or making decisions
- Thoughts of suicide or harming yourself
If you or a loved one are experiencing suicidal thoughts, reach out for help by calling the National Suicide Prevention Lifeline at 1-800-273-8255. The National Suicide Prevention Lifeline is free, confidential, and available 24/7.
How do you fix a chemical imbalance?
Only a healthcare professional can diagnose a chemical imbalance. Chemical imbalances in the brain are usually treated with a combination of psychiatric drugs , talk therapy, and lifestyle modifications. Of the several types of antidepressants that work to balance brain chemicals and boost serotonin activity, selective serotonin reuptake inhibitors are among the most commonly prescribed for treating depression and other mood disorders.

Chemical Imbalance And Depression
Some types of depression may be due to chemical changes in the brain. It is believed that the level of dopamine, or the way in which dopamine receptors work can be a cause of depression. While dopamine has long been considered the reward system of the brain, these neurons can also affect feelings related to pleasure, motivation, and habit forming. When you are bombarded by these changes in the brain, it can affect everything in your daily life.
However, a chemical imbalance does not have to rule your behavior. In therapy, you can be taught new ways to cope with feelings of depression so that you can live a happy, healthful, and normal life.
Use Of Prescription Drugs
Among the neurotransmitters mentioned above, a drop in the serotonin level suggests that a person might feel dejected and hopeless. Because serotonin is also in charge of other bodily functions like sleep, sense of appetite, and the amount of pain we feel, prescription medication like antidepressants claim to bring back the level of serotonin in the body, thereby regulating the imbalance and helping a person feel better again.

Treatment Implications Of The Neurobiological Model
The neurobiological sequelae and repercussions of chronic or recurrent MDD indicate that interventions for MDD should be focused on achieving optimal treatment early. Longitudinal studies have shown that one of the best predictors of remission status at 2 years was response to acute treatment, i.e. initial 6 weeks . In addition, the adequacy of treatment may also have prognostic implications. For patients with late-life depression, exposure to previous inadequate trials of antidepressants resulted in a reduced response rate to pharmacological intervention augmented by psychotherapy compared with treatment of naive patients, even after controlling for baseline severity . Similarly, in a large observational study of 996 patients with MDD, non-response or incomplete response to initial antidepressant treatment was a significant predictor of eventual treatment resistance . On the positive side, an early response to antidepressants has been shown to predict greater treatment adherence .

The Role Of Stress In Depression
There is clear evidence showing that emotional and social stress can lead to clinical depression. While it may seem intuitive how stress can contribute to symptoms of depression, stress doesnt just make us feel overwhelmed and frazzled: it changes our biology.
Stress can trigger the release of hormones and other chemicals that affect many systems in the body. For example, stress can lead to inflammation, changes in blood sugar and the gut microbiome, and more.
When our bodies are not healthy, this response to stress can become exaggerated, leading to chronic or higher levels of inflammation and other changes. This can set the stage for depression.

Molecular Processes Mediating Neurobiological Changes
The alteration in the hippocampus signifies a potential outcome of injurious feedback that occurs via neuroendocrine dysregulation. A consistent finding in patients with MDD is a high level of the stress hormone cortisol, which may cause impairment in neuroplasticity and cellular resistance . An imbalance between glucocorticoid and mineral corticoid receptors in MDD along with high-density glucocorticoid receptors may also contribute to the hippocampus susceptibility to neuronal damage . Subsequent hippocampal atrophy could result in further neuroendocrine dysfunction and hence a potential run-away system . Postmortem comparisons of brain tissue in patients with MDD and age-matched healthy controls have shown hippocampal shrinkage in depressed subjects that was caused by increased density of neuronal cells and a significant reduction in neuropil .

Depression The Chemical Imbalance Myth And What Causes Depression
Depression affects a relatively large portion of Americans. It is normal to feel depressed on occasion, but severe negative moods and lack of interest in what was once considered a pleasurable activity, for a prolonged length of time , may reflect major depressive disorder. Approximately 16% of Americans will experience major depressive order at some point in their lives . Major depressive disorder varies in severity and can persist anywhere from months to years. For some people it becomes debilitating and can contribute to other health problems. Depression is the leading risk factor for suicide, and is among the top three causes of death for people between ages 15 and 35 . Depression may not only alter the life of those who experience it, but also the lives of those close to the sufferer. If you have ever been close with someone suffering major depression you have probably witnessed the life disruption it entails.
Most antidepressants promote the growth of new cells and new brain connections it may be that the primary mechanisms underpinning successful drug treatment involve these factors. Jarrett suggests that the most important action of antidepressants might be to increase the growth of new brain cells.

Do We Have Anything Faster And/or More Effective
Ketamine is known to be faster and ECT is typically more effective. Duman and Aghajanian found that prefrontal cortex and hippocampal damage reversed with ketamine. Ketamine and ECT seem to be more able to stimulate synaptic genesis and turn on rapid-response genes that activate structural genes in the limbic system neurons. It is important to note, however, that even though their focus was on ketamine and its rapid response, other things like antidepressants, exercise, and environmental changes also effectively reverse this damage, albeit more slowly.

Chemical imbalance, which can be triggered by emotional or psychological disorders can cause feelings of depression and anxiety. Let us find out how this malady can be treated.
The human brain is made up of billions of neurons, or nerve cells, which are continuously firing electrical impulses down the axon. One end of the neuron shoots out a chemical, which traverses a synapse and transmits the chemical to another nerve cell. These chemicals are also referred to as neurotransmitters. It is believed that an imbalance in these neurotransmitters is the cause of a chemical imbalance in the brain, and gives rise to feelings of anxiety and mental depression. Some of these neurotransmitters are GABA , dopamine, serotonin, epinephrine, norepinephrine, just to name a few. There are ways to treat this imbalance, which includes the administration of prescription drugs, as well as the use of certain herbal supplements.
A Surprising New Study Published In The Journal Molecular Psychiatry Recently Asserted That There Is No Scientific Evidence To Support The Idea That Depression Is Caused By An Imbalance Of Serotonin In The Brain The Researchers Further Says That Despite That Lack Of Evidence The Public Widely Believes That Low Serotonin Or Chemical Imbalances Cause Depressionand People Are Being Prescribed Antidepressants In Huge Quantities
In an interview with online biotech magazine NEO.LIFE, however, Columbia Bioethics Program Director Dr. Robert Klitzman disagrees with the studys conclusion: Psychiatrists use the term chemical imbalance as a metaphor so the public can understand it. It is more accurate to say, rather than an imbalance, that something chemical is going on in the brains of people with depression.
Klitzman continues by examining the studys focus on serotonin levels in the bloodstream. If depression is caused by low levels of serotonin in the brain, does it follow that correspondingly low levels of this neurochemical would be found in the bloodstream? I would argue that depression may be caused by low serotonin levels in the microscopic spaces or synapses between neurons in various parts of the brain, but that such low levels might not necessarily be found in the bloodstream, said Klitzman.

Depression Treatments On The Horizon
Researchers are studying other molecular pathways in the brain to see what role they may play in depression. It may be that rather than a simple deficiency in one specific brain chemical being the causative factor, some depression symptoms could be related to the relative levels of each type of neurotransmitter in different regions of the brain.
Rather than being a simple equation of some unknown factor causing low levels of one or more neurotransmitters and these low levels creating the symptoms of depression, the actual basis of depression is much more complex. While this complexity is often evident to people living with depression, medical professionals and researchers are still trying to understand the intricate nature of diagnosing and treating the condition.
For example, in addition to the role of neurotransmitters, we know there are multiple factors involved in causing depression ranging from genetic factors and childhood experiences to our present day-to-day lives and relationships. Even inflammation is being explored as a potential contributing factor.
Chemical Imbalance In Depression: What Causes Them
Low neurotransmitter levels may contribute to depression. Studies have identified several possible reasons for chemical imbalances in the brain, such as the following:
- Low levels of enzymes that aid in the production of neurotransmitters
- Insufficient receptor sites to accept the neurotransmitters
- Presynaptic cells reabsorb the neurotransmitter before it reaches the receptor cell
- Insufficient molecules that contribute to the formation of neurotransmitters
- Insufficient production of a specific neurotransmitter

Depression Medications And Treatment
Depression treatment typically uses medications as well as therapy.
Many depression medications increase levels of serotonin and other neurotransmitters in the brain. They do this by preventing nerve endings from reabsorbing the neurotransmitter or preventing the neurotransmitter from being broken down. In either case, the neurotransmitter is more readily available to signal surrounding nerves. Some of the common medications used to treat depression include:
- SSRIs or selective serotonin reuptake inhibitors, which block the reabsorption of serotonin
- SNRIs or serotonin-norepinephrine reuptake inhibitors, which block the reabsorption of serotonin and norepinephrine
- TCAs or tricyclic antidepressants, which block the reabsorption of serotonin and noradrenaline
- NDRIs or norepinephrine-dopamine reuptake inhibitors, which prevent reabsorption of norepinephrine and dopamine
- MAOIs or monoamine oxidase inhibitors, which prevent the breakdown of norepinephrine, serotonin and dopamine
Often, medication is not enough to relieve the symptoms of depression. In addition to medication, therapy can be highly beneficial. One example of therapy for depression is cognitive-behavioral therapy. The goal of this therapy is to modify the thought processes that might be contributing to depression.
There are also methods for chemical imbalance treatment without medication, such as exercise, diet and exposure to light.
Is There A Test To Identify A Chemical Imbalance In The Brain
There are no reliable tests to diagnose a chemical imbalance in the brain.
Doctors can perform tests to assess the levels of serotonin and other chemicals in your blood. However, this is not an accurate representation of the amount of these present in your brain.
A wide range of factors may contribute to a person developing depression. However, family genetics does appear to play a role.
Research shows that a family history of depression 37 percent .
Many smaller studies had identified genetic components that may be associated with depression. However, further, more conclusive research is required to fully assess the exact role genetics has in depression.
