Nearly 80% of people with depression have suicidal thoughts . About 10% to 15% commit suicide . It is crucial to seek help and be aware of warning signs.
In Brazil, 5.8% of the population suffers from depression . The prevalence is 19%, which means one in five people worldwide 2 .
Depression affects more than 300 million people worldwide, according to the World Health Organization 2 .
Among Brazilian teenagers, 20% have mild to moderate depression and 9% have severe depression . For young people aged 16 to 17, 17.1% have severe depression and 13.5% have mild to moderate depression .
Women between the ages of 35 and 50 are at higher risk of depression. This is due to the significant hormonal changes of menopause .
Difference between depression and sadness
Many people use the term 'depression' to refer to passing feelings of sadness. But this is not appropriate, as depression is a serious disorder. Sadness is a natural feeling that helps us cope with loss or suffering . It can last for days, but not weeks, so it is not a sign of depression .
Depression is a deep and unexplained sadness that lasts a long time and affects an individual's life. 4 5 6 It can take months or years to improve if not treated correctly. 5 6
- In sadness, losses are processed more quickly, allowing the person to move on, whereas in depression, losses are more difficult to overcome. 5
- Sadness can be overcome with leisure activities, fun programs, and the company of friends, but depression requires professional treatment that includes therapy, medication, and changes in lifestyle. 5
Sadness does not affect productivity, but depression can affect many aspects of life, such as health and relationships 4 6. In addition, depression can lead to suicidal thoughts, which does not occur with sadness 4 6 .
"Sadness seems to be the most enduring feeling, but its duration should be days, not weeks; otherwise, it may signal depression."
Understanding the difference between sadness and depression is crucial for getting the right treatment and regaining mental health 4 5 6 .
Causes of depression
Depression is a complex condition that can be caused by a combination of genetic and environmental factors . Studies show that stress can suppress the production of new neurons in the hippocampus. This contributes to the development of depression.
Furthermore, magnetic resonance imaging revealed that the size of the hippocampus in depressed women can be 9% to 13% smaller. This occurs in comparison with non-depressed women, and the difference increases with more episodes of depression 7 .
Evidence shows that depression is a hereditary disease. It affects more those whose first-degree relatives have depression. Personal characteristics, such as high neuroticism, also increase susceptibility to depression .
Genetic and environmental factors
Trauma and prolonged stress can trigger depression in genetically predisposed individuals. Unhealthy lifestyle habits , such as sedentary behavior and an unbalanced diet, also contribute to the development of depression .
Fortunately, depression is a treatable illness . The main treatment involves psychotherapy and psychopharmacology . Cure rates are high, reaching 90-95 % of cases. During pregnancy and postpartum, it is crucial to have a professional assessment and establish appropriate treatment.

Depression is a mental disorder that profoundly affects an individual's emotions, behavior, and physical health. It is characterized by persistent feelings of sadness, apathy, loss of interest in previously pleasurable activities, and difficulty performing everyday tasks.<sup> 10</sup>
In addition to emotional symptoms, depression can also lead to problems with sleep, appetite, concentration, and memory, as well as unexplained physical symptoms. It is a serious illness that requires treatment, as it significantly impairs a person's quality of life.<sup> 10</sup>
It is estimated that more than 300 million people suffer from depression worldwide 10. Around 800,000 people die by suicide each year, making it the second leading cause of death among people aged 15 to 29 10. Unfortunately, less than half of those affected worldwide (in many countries, less than 10%) receive known effective treatments for depression 10 .
In Brazil, the lifetime prevalence of depression is approximately 15.5%, according to epidemiological studies.11 The prevalence rate of depression in the primary health care network, alone or associated with a physical disorder, is 10.4 % according to the WHO.11 Studies indicate a lifetime prevalence of depression of up to 20% in women and 12% in men.11
It is important to understand that depression is a serious illness and should not be confused with passing sadness. It is essential to seek professional help to obtain an accurate diagnosis and start appropriate treatment in order to improve the quality of life of those affected. <sup>10</sup>

In Brazil, more than 11 million individuals suffer from this mental disorder. The disease can be classified according to its severity, duration, and symptoms.
There are important distinctions, such as between depression in people with or without a history of mania. Furthermore, depression can be mild, moderate, or severe, depending on the intensity of the symptoms . A mild episode may cause some difficulty, while a severe one may prevent a person from carrying out their daily activities.

Diagnosis of depression
Depression is diagnosed by a specialist doctor, usually a psychiatrist. They talk to the patient about their life and observe the symptoms. If necessary, they order tests to rule out other causes.
Medical evaluation is the first step. The psychiatrist asks about the patient's history and symptoms. More than half of people with depression do not have access to treatment . This conversation is crucial for choosing the best treatment.
The doctor may order additional tests to rule out other causes. This is important because depression can be linked to other health problems.
After analyzing everything, the psychiatrist classifies depression as mild, moderate, or severe. Less than 10% of people with depression receive effective treatment . This classification helps in choosing the right treatment.
A Careful and Personalized Approach
There is no single specific test to diagnose depression. The diagnosis is made by a doctor through conversations and mental health assessments . Each person is unique, so the assessment must be personalized.
During the pandemic, anxiety and depression increased by 25% 15. Early diagnosis and treatment are crucial for taking care of mental health.
In short, diagnosing depression is a careful process. A psychiatrist evaluates the patient and, if necessary, orders tests. This determines the severity of the depression and the best treatment for each individual.
"There is no specific test to confirm depression; the diagnosis is made by a doctor based on conversations and mental health assessment tests."
Treatment for depression
Treatment for depression involves antidepressant medication and psychotherapy.16 Medications help balance neurotransmitters in the brain. Therapy, such as CBT, helps change the patient's thinking.17 The goal is for the patient to learn to live without medication after a while .
Sometimes therapy alone is necessary. Other times, medication and therapy are used together 17. Lifestyle changes also help, such as exercising, eating well, and practicing yoga and meditation 17 .
- Cognitive Behavioral Therapy (CBT): An effective approach in the treatment of depression, focused on the present and problem-solving 17 .
- Antidepressant Medications: Frequently prescribed in cases of moderate or severe depression, with the function of replenishing brain neurotransmitters such as serotonin and norepinephrine 17 .
- Natural Treatments: Physical exercise, a healthy diet, vitamins B and D, as well as alternative therapies such as yoga, Reiki, acupuncture, and meditation, can contribute positively to combating depression 17 .
- Electroconvulsive Therapy: A treatment option in very severe cases, performed two to three times a week for a total of 6 to 12 sessions 17 .
Treatment for depression can take from 6 months to several years 17. There are new therapies under development, such as TMS, MST and tDCS, but not all are available in Brazil 18 .
"Depression can trigger cardiovascular diseases such as heart attack, stroke, and hypertension, highlighting its influence on overall health." 16
