To better understand what causes depression, it is necessary to explore a variety of biological, psychological and environmental factors that may play a role in the development of this condition.
Biological factors
Biological factors play an important role in the onset of depression.

These chemicals, known as neurotransmitters, are responsible for regulating mood, energy and motivation.
In addition, genetics can also influence the predisposition to depression. Studies have shown that people with a family history of depression have a higher risk of developing the disease. Although genetics does not definitively determine who will develop depression, it can increase a person's vulnerability to triggers.
Neurobiology of depression
The neurobiology of depression is an area research in constant evolution. It has been found that certain brain regions, such as the hippocampus and prefrontal cortex, may show structural and functional differences in people with depression. These alterations can affect the brain's ability to regulate emotions and respond appropriately to stress.
In addition, neuroimaging studies have revealed that depression may be associated with changes in the connectivity of brain networks, which can influence cognitive and emotional processes. Understanding the neurobiology of depression is essential for the development of more effective and personalized treatments.
Psychological factors

Identifying environmental factors that contribute to depression can help people take steps to improve their emotional well-being and reduce their vulnerability to illness.
In conclusion, depression is a complex mental disorder that results from the interaction of multiple biological, psychological and environmental factors.
