Causes of Depression

Causes of Depression

The key to understanding the causes of depression – and, in fact, makes any mental disorder – is that still do not know what causes these mental disorders. It is generally believed that all mental disorders are caused by a complex interaction and combination of biological, psychological and social factors. This theory is called the bio-psycho-social model of causality and is the most widely accepted cause of disorders such as depression by professional theory.

Some types of depression run in families, suggesting that a biological vulnerability can be inherited. This seems to be the case with bipolar disorder. Studies of families in which members of each generation bipolar disorder found that people with the disease have a somewhat different from those who do not become ill develop genetic makeup. However, the opposite is not true: Not everybody with the genetic makeup that causes vulnerability to bipolar disorder will have the illness. Apparently additional factors, possibly stresses at home, work or school, are involved in its onset.

In some families, major depression also seems to occur generation after generation. However, it can also occur in people who have no family history of depression. Whether inherited or not, major depressive disorder is often associated with changes in brain structures or brain function.

People who have low self-esteem, who consistently view themselves and the world with pessimism or who are readily overwhelmed by stress, they are prone to depression. Whether this represents a psychological predisposition or an early form of the disease is unclear.

In recent years, researchers have shown that physical changes in the body can be accompanied by mental changes. Medical illnesses such as stroke, heart attack, cancer, Parkinson’s disease, and hormonal disorders can cause depressive illness, making the sick person apathetic and unwilling to care for their physical needs, thus prolonging the recovery period . Also, a serious loss, difficult relationship, financial problem, or any stressful change (unpleasant or even desired) in life patterns can trigger a depressive episode. Very often, a combination of genetic, psychological and environmental factors are involved in the occurrence of a depressive disorder.

  2. Biological / Biochemical / Medicines
  3. Dietitian
  4. Environmental
  5. Socio Cultural factors / situations / Relationships / Personality

In some families, depression seems to run through the generations. Such cases are hereditary and is believed to a particular chromosome may be the culprit. This issue is still under investigation and no particular chromosome has been identified yet.

  1. Biological / Biochemical / Medicines

Some diseases or medical conditions may also cause depression. These are – hormonal disorders (eg, perimenopause or hypothyroidism in women), cancer, heart disease leading to stroke, diabetes, Parkinson’s disease and Alzheimer’s disease. A long-term illness that lasts for years is also a cause of depression. The elderly is combined with various diseases can lead to manic depression. Some people can suffer from multiple diseases simultaneously. This can strain the physical body and the emotional mind, resulting in depression.

Sometimes the cause of depression is biochemical. chemical equilibrium of the human body may be interrupted due to various factors resulting in depression. When there is an imbalance in the level of chemicals which act as neurotransmitters in the brain, it can cause depression.

Causes of depression medication

Certain medications we take to cure the disease can in turn become a cause of depression. Examples include: – medicines to control seizures (eg, Neurontin and Lamictal), drugs to control blood pressure, sleeping pills to induce sleep; antibiotics to control the spread of infection, all can induce depression in people using these drugs.

However, a factor that can not be overlooked here is substance abuse or drug abuse that often leads to depression. Self-medication is considered as drug abuse often leads to depression. Alcohol, people take to feel better, can lead to depression, if taken in large quantities, or when a person becomes addicted. Older people are more likely to become depressed when under medication, that young people are.

Many people around the world do not have access to proper diet and daily intake of nutrients, protein, vitamins and minerals to be deficient. They are in a high risk category. Deficiency of folic acid and vitamin B12 is related to the onset of depression. By contrast, people who regularly consume foods rich in what makes them obese also suffer from depression.

  1. Environmental

The appearance of certain seasons also lead to depression. These are commonly known as seasonal affective disorder. The exact cause is reduced or increased the amount of sunlight that disturbs the chemical balance of the body and especially the brain chemistry. This in turn makes it inhibits production or excess mood control chemicals which can result in depression.

  1. Socio-cultural factors / human relations / personality / Situations

Social factors such as discrimination based on sex, cast, religion and social status are factors that lead to depression known. Living and working in stressful social conditions, harassment of various forms, isolation, denial and violation of the rights of other social causes of general depression, those belonging to lower sectors of society with limited access to health services access are at a higher risk of becoming depressed. that persons belonging to other sectors of society. Similarly, older people living alone in a closed society, are at greater risk of depression than others. Normally women are more susceptible to depression than men in any society.


Cultural factors that impose various forms of restrictions, for example, in expression, communication, movement, diet, etc. can lead to depression. limited interaction decreases consciousness that leads to an inability to learn ways to cope with various medical and physical conditions also leads to depression. Women are more likely to develop depression due to cultural factors that impose more responsibility to them than men. With the restrictions on movement and links with the outside world, women are mostly ignorant about depression, as well as the many ways to deal with it.


Human relationships and behavior are the main factors are often the source of depression. Discontent, seclusion, undisciplined and abusive behavior, obsessive-compulsive disorder (OCD), bereavement and long-term disease of the near and dear ones can lead to depression.

adverse situations that people face in their everyday life regarding employment, income, family, are causal factors that lead to depression.

All these causes may act either individually or in combination, and will result in different levels of depression in humans. The human brain is more developed than that of animals. It is able to react to various stimuli. It is therefore logical that all humans experience some degree of depression.
