what cause depression : Causes and Risk Factors Must Read | Technihelps

what cause depression Depression is one of the most common mental disorders in the United States. It can affect anyone at nearly any age, but the reasons some people become depressed are not always known. Researchers doubt there are actually many different causes of depression and that it is not always preventable. Parts that can contribute to depression include heredity, brain chemistry, some medical conditions, substance use, stress, and poor nutrition.

It is expected that 10% to 15% of the global population will feel clinical depression in their lifetime. The World Health Organization estimates 5% of men and 9% of women feel depressive disorders in any provided year.

 

Brain & Body Risk Factors

There are several different things that can make depression including factors related to the brain and body. Amazing things that can increase your risk for depression include the understanding.

Brain Chemistry Inequalities

One possible biological cause of depression is an imbalance in the neurotransmitters which are included in mood regulation.2 Certain neurotransmitters, including dopamine, serotonin, and norepinephrine, play an important role in mood.

Neurotransmitters are synthetic substances that help different areas of the brain communicate with each other. When certain neurotransmitters are in short supply, it may lead to the signs we recognize as clinical depression.

This theory of depression suggests that having too much or too little of certain neurotransmitters causes, or at least offers to, depression. While this information is often cited as a primary cause of depression, it remains unproven and many experts believe that it doesn’t paint a complete picture of the complex parts that contribute to depression.

Medications to treat depression often focus on altering the levels of certain chemicals in the brain. Some of these treatments include selective serotonin reuptake inhibitors (SSRIs), serotonin-norepinephrine reuptake inhibitors (SNRIs), monoamine oxidase inhibitors (MAOIs), and tricyclic antidepressants (TCAs).

Physical Health & Certain Medical Conditions

You may be more likely to feel symptoms of depression if you have a chronic illness, sleep disorder, or thyroid condition. Depression rates also tend to be higher among people who have chronic pain, diabetes, multiple sclerosis, and cancer.1

The mind and the body are linked. If you are experiencing a physical health problem, you may discover changes in your psychic health as well. 

Illness is related to depression in two ways. The stress of having a chronic disease may trigger an episode of major depression. In addition, certain illnesses, such as thyroid disorders, Addison’s disease, and liver disease, can cause depression symptoms.3

Female Sex Hormones

It has been widely documented that women experience major depression about twice as often as men. Because of the incidence of depressive disorders peaks as women’s reproductive years, it is believed that hormonal risk factors may be at play.4

Women are especially prone to depressive disorders during times when their hormones are in flux, such as around the time of their menstrual period, pregnancy, childbirth, and perimenopause.

Hormone changes caused by childbirth and thyroid conditions can also contribute to depression. Postpartum depression may occur after a woman has given birth and is believed to occur from the rapid hormonal changes that take place immediately after giving birth.

In addition, a woman’s depression risk declines after she goes through menopause.

Family History & Genetics

A family history of depression is another significant risk factor. You are more likely to experience symptoms of depression if others in your family also have depression or another type of mood disorder. Estimates suggest that depression is approximately 40% determined by genetics.4

Twin, adoption, and family studies have linked depression to genetics. While studies suggest that there is a strong genetic component, researchers are not yet certain about all the genetic risk factors for depression.1

Researchers have found that having a parent and grandparent with depression doubles the risk of depression.2

It is still unclear exactly which genes play a role in depression and other mood disorders, but researchers do know that there are many different genes that can play a role. By better understanding how they function, gene researchers hope to be able to create more effective treatments.

It is important to remember that no single cause of depression acts in isolation. Genetic factors may be a major risk factor, but scientists also believe that genes and the environment interact to control exactly how these genes are expressed.
