What is depression?
In the following paragraphs, we will attempt to clarify the most important types of diagnosed depression, one of the most common and widespread mental health problems, which can significantly and negatively impact daily life.
A person with depression may remain in a low mood, find it difficult to experience joy, lose interest in their usual pursuits, and lack the energy to engage in any activities.
These symptoms are not temporary but persist for extended periods, weakening their ability to live a normal life.
There is no single type of depression, but some types are situational, psychotic, or dysthymic, in addition to bipolar disorder, and other types.

What causes depression?
Depression is a psychological problem that doesn’t have a single direct cause. Rather, it develops as a result of many factors, including biological, environmental, personal, and genetic ones.
- Regarding biological factors, these are primarily related to brain chemistry; an imbalance in the levels of certain chemicals negatively affects psychological and emotional state.
- As for environmental factors, these can be expressed as psychological and emotional stress, deeply saddening events, and other environmental factors.
- Regarding personal factors, the chances of suffering from depression increase for those who are self-critical or who strive for perfection.
- Regarding genetic factors, if a family member has suffered from depression, your chances of experiencing it increase.
- Chronic inflammation and excessive cortisol production.
- Systemic diseases such as diabetes and heart disease.
How is depression diagnosed?
Depression is diagnosed by assessing the patient’s condition based on their symptoms, medical history, and mental health history.
This does not preclude the possibility of needing some tests and examinations to rule out the possibility of a specific health problem contributing to the development of the depression.
How is depression treated?
Most people with depression who seek proper treatment experience significant improvement.
For mild depression, a doctor may recommend individual and family therapy, along with some exercise. If there is no improvement, talking therapy may be considered.
For moderate or severe depression, medication is prescribed in addition to talking therapy.
What is the prognosis of depression?
The prognosis of depression varies widely. With appropriate treatment, about 70–80% of patients experience significant symptom improvement, although full remission rates are lower (around 30–50%).
Acute depressive episodes may resolve within several months, but some cases persist longer or become chronic if untreated.
Relapse is common, with rates ranging from 30% to 80%, particularly within the first two years after recovery.
Early detection and timely treatment significantly improve outcomes and reduce the risk of recurrence.
Can I prevent depression?
Depression cannot be completely prevented due to biological and environmental factors. However, evidence shows that lifestyle modifications, such as stress management, regular physical activity, a healthy diet, adequate sleep, and strong social connections, can significantly reduce the risk.
Additionally, psychological interventions like cognitive behavioral therapy and early support for high-risk individuals can further lower the likelihood of developing depression.
When should I see my healthcare provider about depression?
You should consult the healthcare provider if bothersome symptoms persist for an extended period, negatively impacting your daily life, work, studies, sleep, and your mental, emotional, and psychological conditions.
You should also seek immediate medical consultation if you experience suicidal thoughts or self-harm.
