Depression is caused by complex interactions between biological, psychological, and social factors. Life events like loss, childhood adversities, and unemployment can cause or increase the chances of someone developing depression.

Depression can be treated by the use of pharmacological and psychological treatments. However, support services and treatment for depression in low- and middle-income countries are underdeveloped or unavailable. Over 70% of people suffering from depression in these countries cannot receive treatment.

Depression affects several aspects of a person’s life. It affects their relationship with friends and family, their productivity at work, performance at school, and their ability to be involved in community activities.

Research indicates that there is a connection between depression and physical health. Depression affects people of all ages and economic statuses. However, women are more likely to suffer from depression compared to men.

  • Abuse – emotional, physical, and sexual abuse can lead to depression later in life.
  • Age – the elderly are more likely to suffer from depression. This factor can worsen if they live alone or lack social support.
  • Certain medications -medication such as corticosteroids often increase the risk of depression.
  • Conflict – disputes with friends and family members can increase the risk of depression in biologically vulnerable people.
  • Gender – women have a higher chance of developing depression compared to men. This could be a result of the hormonal changes that women go through.
  • Genes – having a family history of depression increases the risk of depression. However, it is not clear how genes increase the risk of depression.
  • Loss or death – grief and sadness that occurs when a person loses their loved one increases the risk of depression.
  • Major events – interestingly, even good events such as getting married or graduating can increase the risk of depression. Negative events such as losing a source of income and divorce also increase the risk of depression.

The link between Depression and Major Risk Factors

How is depression linked to biology?

Researchers have identified differences in the brains of people suffering from clinical depression and those without. People who have previously suffered from depression have a smaller hippocampus compared to people who have never suffered from depression.

Additionally, they have fewer serotonin receptors. However, it has not been established why this is so. Some scientists believe that people who suffer from depression are born with a smaller hippocampus.

Does depression occur with grief?

Grief is a common response to loss. Grief can be caused by a loss in the form of loss of a job, death, loss of a pet, separation from a loved one, retirement, and divorce.  Anyone can experience loss and grief.

However, not everyone who experiences loss and grief suffers from clinical depression. Depression is different from grief. Symptoms of depression include a feeling of low self-worth and esteem, suicide, and negative thoughts of the future. Grief is characterized by feeling empty and longing for a loved one.

What is the link between chronic pain and depression?

Chronic pain interferes with a person’s sleep, productivity at work, relationships, and ability to exercise physically. These effects are likely to leave one feeling isolated, sad, and depressed.

what is the link between chronic illness and depression?

chronic illness in some people leads to depression. Chronic illnesses that are likely to cause depression include heart disease, diabetes, kidney disease, HIV and AIDS, lupus, multiple sclerosis, and arthritis.

Can certain drugs cause depression?

Certain drugs can cause depression in certain people. Medications such as acne isotretinoin, barbiturates, and benzodiazepines have been linked to some cases of depression. Medications used to control blood pressure are also linked to depression.

How is genetics Linked to Depression?

Sometimes depression can run in the family suggesting that there is some link between genetics and depression. No single gene is responsible for depression but rather several genes that contribute small effects that lead to depression when they interact with their environment.


Depression is a form of mental illness. Several factors such as age, gender, loss, substance abuse to name but a few, are the causes of depression.
