Depression is an illness that mostly results from an imbalance of chemicals in the brain. These chemicals are called neurotransmitters. The ones affected are associated with neural pathways that control mood.

There isn’t just one cause for depression. In fact, finding a cause can be rather complex in its nature. Many of the causes that scientists and doctors have come up with are still being tested. Start with this list and follow up with your doctor for more in-depth information.

1. Heredity – Like other conditions such as alcoholism, you are at a greater risk if someone in your family also has the condition. Those with family members suffering from depression or who have succumbed to a depressive symptom (suicide) are more likely to develop depression according to the experts. They have not identified which types of depression that includes as yet.
2. Illness – There seems to be a correlation between illness and depression. This refers to prolonged illness like cancer, HIV/AIDS, diabetes and heart disease. If you already have been exhibiting symptoms of depression before these illnesses your risk is greater.
3. Personality type – People who exhibit low self-esteem, poor body image, inability to handle stress, feelings of isolation and negative thinking are more likely to become depressed.
4. Nutritional deficiencies – What you eat is important. When your diet lacks vitamins and minerals instrumental in brain health, depression could become a reality in your future.
5. Medications – Some medications may have side effects that can lead you to depression. If you’ve ever read the list on the bottle, prolonged use of some can increase depressive symptoms.

Are you concerned that something in your life may be a cause for depression? You won’t know for sure unless you see a professional.
