How does the brain deal with depression? Rather, there are many possible causes of depression, including faulty mood regulation by the brain, genetic vulnerability, stressful life events, medications, and medical problems.

Depression is a mood disorder that affects the way you think, feel, and behave. It causes feelings of sadness or hopelessness that can last anywhere from a few days to a few years. This is different than being upset about a minor setback or disappointment in your day. It’s complicate and there are multiple causes of major depression. Factors such as genetic vulnerability , severe life stressors , substances you may take (some medications , drugs and alcohol ) and medical conditions can affect the way your brain regulates your moods.

The biological factors that contribute to depression include: Physical changes to the brain – it is known that some part of a depressed brain show less activity. Neurotransmitters – these chemical messengers in the brain have been implicated in the cause. Hormones – hormone changes may.

Early childhood trauma.

Traumatic events during childhoo such as physical or emotional abuse , or loss of a parent, may cause changes in the brain that make a person more susceptible to depression. There is also evidence that reduced dopamine levels can contribute to depression in some people. When other treatments have faile medications that behave like dopamine or stimulate the release of the neurotransmitter in the brain have worked for some people with depression. Certainly in many cases, there is a reduction in the amount of certain neurotransmitters found (monoamines such as serotonin and norepinephrine) in depressed people.

In some people, a chronic illness causes depression. A chronic illness is an illness that lasts for a very long time and usually cannot be cured completely. However, chronic illnesses can often be controlled through diet, exercise, lifestyle habits, and certain medications. While poor sleep habits are a common symptom of major depression , there is some suggestion that lack of adequate sleep may also be a risk factor for developing depression.

Excessive alcohol consumption or the abuse of drugs or other substances often occur in tandem with major depression. Actually, there are numerous chemical reactions that take place both inside and outside of our brain ,. In summary, we know that depression causes a smaller hippocampus in the brain , but we can reverse this damage. Our thoughts and emotions play a huge role in our mental health, but conventional medicine doesn’t seem to guarantee a recovery, or even a small breakthrough, in many cases.

Most likely, depression is caused by a combination of genetic, biological, environmental, and psychological factors, according to the NIMH. Certain medical conditions may also trigger depression , including an underactive thyroid glan cancer, heart disease, prolonged pain and other significant illnesses. The medical community largely presumes that depression is caused by low levels of so-called feel-good brain chemicals, usually serotonin and sometimes dopamine. But this is only a theory — albeit a very widely held one! It stimulates a tiny electrical current in a part of the brain linked to depression.

TMS does not cause a seizure and appears to have few side effects.

But doctors are still fine-tuning this. By measuring these metabolites, researchers can gain an understanding of the effects of changes in neurotransmitters in the brain. It is unknown whether changes in levels of neurotransmitters cause the development of depression or depression causes changes in neurotransmitters.

It may happen both ways.
