According to the World Health Organization, depression is the leading cause of disability and contributes significantly to the global burden of disease.

It is a complex disorder that influences mood, thinking, behavior, and physical functioning. It is characterized by profound sadness, loss of interest, changes in appetite and sleep, fatigue, guilt feelings, and difficulties in concentration.

In any case, specialized medical attention is required for timely diagnosis and treatment.

It is not a simple decline in mood or emotional state, as it can lead to the emergence of other diseases such as stress, phobias, anxiety, obsessive disorders, and in the worst of cases lead to suicide.

The genetic composition and functioning of brain neurotransmitters, defined as those chemical substances, that help transmit messages between nerve cells in the brain, have a significant influence.

Its causes are multiple, and include personal and/or family history of depression; chemical, genetic, and hormonal composition, exposure to stressful situations and traumas, economic problems, employment or unemployment, loss or illness of a loved one or pet, breakups, divorce, among others.
