What Is Depression? (Major Depressive Disorder)
Depression is a mood disorder characterized by persistent sadness, low energy, loss of interest, or feelings of hopelessness. Depression can affect anyone, regardless of age or background, making awareness essential.
Causes of Depression
Depression does not have one single cause. Instead, depression arises from a combination of biological, psychological, and environmental factors.
1. Genetic Factors
People with a family history of depression may have a higher risk. Genetics can influence how brain chemicals respond to stress or emotions.
2. Biochemical Imbalances
Changes in neurotransmitters such as serotonin, dopamine, and norepinephrine can trigger depression symptoms. Many depression medications target these chemical imbalances.
3. Environmental Stressors
Stressful life events can increase depression risk:
-
trauma or abuse
-
financial problems
-
chronic stress
-
loss of a loved one
-
relationship issues
Stress management can reduce depression risk and improve mental health.
4. Medical Conditions
Chronic illnesses, hormonal changes, vitamin deficiencies, and certain medications can contribute to depression symptoms.
5. Psychological Factors
Low self-esteem, negative thinking, unresolved trauma, or prolonged worry can increase the risk of depression.
