Causes
The exact cause of depression is not fully understood, but several factors play a role, including:
- Brain Chemistry: An imbalance in neurotransmitters, such as serotonin and dopamine, is thought to contribute to depression.
- Genetics: Having a close relative with depression increases your risk of developing the condition.
- Stressful Life Events: Significant challenges, such as losing a loved one or experiencing trauma, can trigger depression.
- Medical Conditions: Chronic illnesses like diabetes or ongoing pain can lead to depression.
- Medications and Substances: Certain medications and substance use, including alcohol, can worsen or contribute to depression.
Types of Depression
According to the DSM-5, depression is classified into several types:
